Fuel Cards for Owner-Operators: Finding the Real Savings

A fuel card does not save money because the provider advertises a large discount.

It saves money only when the carrier buys fuel at a lower net operating cost than the realistic alternative.

That result depends on more than cents per gallon.

It depends on:

• the station’s starting price;
• the card’s final price;
• network coverage;
• route deviation;
• transaction and account fees;
• payment timing;
• fuel quality and amenities;
• fraud control;
• tax records;
• whether the card is consistently accepted.

An owner-operator should therefore compare fuel cards as route-finance tools, not as coupon programs.

The number that matters: net delivered fuel cost

The most useful fuel-card calculation is:

Net delivered fuel cost = fuel purchase + card fees + route cost + payment cost − rewards retained

This is broader than the pump receipt.

Fuel purchase

• gallons multiplied by the actual card price.

Card fees

• transaction;
• account;
• card;
• network;
• transfer;
• funding;
• statement.

Route cost

• diesel burned during the detour;
• driver time;
• tolls;
• schedule disruption;
• parking risk.

Payment cost

• late fee;
• returned payment;
• financing cost;
• credit-card funding surcharge;
• lost cash availability.

Rewards retained

• loyalty points;
• free showers;
• parking credits;
• other benefits the owner actually uses.

The card with the greatest advertised discount can lose after all five categories are included.

Start with final price, not discount size

Suppose two truck stops are available on the route.

Location	Posted price	Card discount	Final price
Stop A	$4.19	$0.55	$3.64
Stop B	$3.79	$0.20	$3.59

Stop A advertises the larger discount.

Stop B sells the cheaper diesel.

On 150 gallons:

• Stop A: $546.00;
• Stop B: $538.50;
• Stop B saves another $7.50.

The discount is only meaningful when its reference price is known.

Four common discount structures

Fuel-card programs can describe savings in several ways.

Retail-minus pricing

The card subtracts a stated amount from a retail or posted price.

Example:

• posted diesel: $4.05;
• discount: $0.25;
• card price: $3.80.

Questions:

• Is the reference the credit price or cash price?
• Is the discount fixed?
• Does it vary by station?
• Is it delivered as an immediate price or later rebate?

Cash-price discount

The program can advertise a reduction from the station’s cash price.

This avoids comparing the card with a higher credit-card price.

Confirm the actual price shown in the app or network directory.

Cost-plus pricing

The price can be based on a wholesale or rack-related fuel cost plus:

• taxes;
• freight;
• merchant margin;
• network margin;
• provider charge.

Cost-plus can create strong savings at participating locations.

It can also vary significantly by market and day.

The phrase does not reveal the final price by itself.

Rebate pricing

The driver pays the pump price and receives a later rebate or statement credit.

The carrier should confirm:

• rebate calculation;
• timing;
• exclusions;
• gallon cap;
• station eligibility;
• effect of late payment;
• whether the rebate can be forfeited.

Immediate discounts improve cash flow more directly than rewards paid later.

Published savings are marketing measures

Current trucking fuel-card websites advertise savings in different forms.

Examples available in July 2026 include:

• average savings;
• maximum savings;
• in-network discounts;
• no in-network transaction fees;
• a discounted price visible in an application;
• broad acceptance combined with a smaller discount network.

These measures are not directly comparable.

Average discount

Ask:

• average across which customers;
• which dates;
• which network;
• compared with which price;
• weighted by gallons or transactions.

Maximum discount

A maximum can occur:

• at one location;
• for one fuel type;
• during one pricing period;
• under a promotion.

It should not be used in an annual budget.

Network count

Thousands of stations can sound extensive.

The useful count is the number that fits:

• the carrier’s lanes;
• truck access;
• hours;
• diesel availability;
• parking and operational needs.

Network coverage is a route question

An owner-operator running the same regional lanes needs a different card from a truck that crosses the country.

Map the last:

• 30 days;
• 90 days;
• full seasonal cycle.

For each fuel purchase, identify:

• route;
• gallons;
• station;
• price;
• distance from route;
• card eligibility;
• transaction fee;
• parking or service need.

Then calculate the percentage of gallons that could realistically receive the discount.

Nominal coverage versus usable coverage

A card can advertise 4,000 participating stations.

Only 20 can matter to a particular carrier.

A smaller network can be superior when it covers:

• home terminal;
• regular shipper lane;
• primary interstate;
• preferred overnight stops.

Do not force every purchase into one network

The cheapest fuel plan can use:

• Card A on primary lanes;
• Card B as regional backup;
• ordinary payment where neither card is competitive.

The second card must justify its own:

• monthly fee;
• deposit;
• funding requirement;
• reconciliation work.

Calculate the detour

A discounted station can sit several miles away from the efficient route.

The detour creates two fuel purchases:

1. fuel bought at the station;
2. fuel consumed to reach it.

Illustrative detour

Assume:

• 20 additional route miles;
• truck efficiency: 6.5 mpg;
• diesel: $4.00 per gallon.

Detour fuel consumed:

• 20 ÷ 6.5;
• approximately 3.08 gallons.

Detour fuel cost:

• 3.08 × $4.00;
• approximately $12.32.

Now assume the discount station saves:

• $0.35 per gallon;
• on 150 gallons;
• equals $52.50.

Net fuel saving before time:

• $52.50 − $12.32;
• equals $40.18.

The stop can still be worthwhile.

The decision changes when the detour is longer, gallons are lower or schedule time is expensive.

Add time

Suppose the detour adds:

• 35 minutes.

If the owner’s working time is valued at $40 per hour:

• 35 minutes costs approximately $23.33.

Adjusted saving:

• $40.18 − $23.33;
• equals $16.85.

The advertised $52.50 saving has become $16.85.

Payment model changes the card’s value

Fuel cards can operate through different funding structures.

Prepaid card

The carrier loads funds before purchases.

Advantages

• accessible without a large credit line;
• direct spending control;
• no ordinary credit balance;
• limited exposure if card controls are strong.

Costs and risks

• cash tied up before fueling;
• transfer delay;
• rejected transaction when balance is low;
• account-funding fee;
• difficulty covering unexpected price or gallon increases.

A prepaid discount can be attractive but provide no working-capital relief.

Debit-linked or pay-as-you-go program

The transaction draws from a linked bank account or payment method.

Advantages

• no large prefunded balance;
• automatic settlement;
• simple one-truck workflow.

Costs and risks

• insufficient-funds failure;
• bank timing;
• returned-payment fee;
• card-funded payment surcharge;
• direct account exposure.

The carrier should maintain an operating buffer above expected fuel spend.

Charge card

The provider permits purchases during a billing period and requires the balance to be paid under short payment terms.

Advantages

• payment float;
• consolidated statement;
• no need to preload each transaction;
• useful spend controls.

Costs and risks

• late-payment fee;
• suspension after missed payment;
• personal or business guarantee;
• short repayment cycle;
• automatic debit.

A charge card can provide days of working capital without behaving like a revolving credit card.

Credit product

The carrier receives a credit line and repays according to the agreement.

Advantages

• working-capital flexibility;
• broader acceptance in some programs;
• emergency capacity.

Costs and risks

• interest or finance charges where applicable;
• late fees;
• credit review;
• guarantee;
• lower limit than expected;
• rewards lost after delinquency.

The owner should compare the fuel discount with the financing cost.

Structure	Cash required before purchase	Main risk
Prepaid	Yes	Insufficient loaded balance
Debit or pay as used	Funds available in linked account	Returned payment or account interruption
Charge	No, within approved terms	Short due date and late-payment exposure
Credit	No, within credit limit	Interest, fees and credit dependency

Build the complete fee inventory

A provider can say:

• no transaction fees;
• no monthly fees;
• no hidden fees.

The contract can still contain charges in another category.

Review the complete fee schedule.

Account setup fee

Charged when the account is opened.

It can apply:

• once per company;
• per program;
• after reactivation.

Monthly account fee

Charged regardless of the number of transactions.

A card needs enough monthly gallons to overcome it.

Per-card fee

A one-truck owner can still need:

• primary card;
• driver card;
• replacement or backup card.

Confirm whether inactive cards generate fees.

Transaction fee

Can apply:

• per fuel purchase;
• outside a discount network;
• for cash advance;
• for non-fuel purchases;
• at certain merchant types.

A small transaction fee can materially reduce savings on partial fills.

Out-of-network fee

A card can be widely accepted but charge for transactions outside its preferred network.

Wide acceptance is not the same as wide discount coverage.

Funding or transfer fee

Possible when loading a prepaid account through:

• ACH;
• debit card;
• credit card;
• wire;
• expedited transfer.

The payment method can cost more than the discount.

Late-payment fee

Charge-card and credit programs can impose substantial late fees.

A missed automatic debit can also cause:

• card suspension;
• discount removal;
• reduced limit;
• returned-payment fee.

Replacement-card and express-shipping fee

A lost card can require overnight replacement.

The owner should know the emergency option before the card is lost.

Statement or research fee

Possible for:

• paper statements;
• reproduced reports;
• transaction research;
• custom data.

Electronic access should be tested during the application period.

Current public fee examples

Public provider pages show why account-specific terms matter.

TCS

TCS states that owner-operator customers receive no transaction fee when fueling at more than 2,300 in-network locations.

The carrier still needs the complete agreement for:

• out-of-network use;
• funding;
• account operation;
• payment terms.

WEX Fleet One EDGE

WEX states that the Fleet One EDGE card has no transaction fee at specified discount locations and that an out-of-network fee can apply at other OTR locations.

This is the classic network distinction:

• accepted;
• discounted;
• fee-free

are three different questions.

RTS

RTS publicly advertises average savings, thousands of participating locations and owner-operator programs with no monthly fee.

The individual proposal should still define:

• card option;
• payment structure;
• transaction charges;
• factoring bundle;
• network.

Comdata

Comdata’s small-fleet page displays different plan structures.

One published plan shows:

• $8 per card per month;
• $50 account setup;
• no card transaction fee.

Other Comdata options show different account charges or bundles.

The product name and fee summary must match the application being signed.

AtoB

AtoB publicly displays plan structures that include active-card charges and a flat fee for certain small Flex accounts.

Its owner-operator materials also describe a setup fee for specified plans.

Partner versions can use different pricing.

Mudflap

Mudflap states that its fuel card has no annual fee, monthly service fee or interest.

State offer summaries can still identify avoidable charges such as:

• non-ACH payment fee;
• late fee;
• returned-payment fee.

The lesson is not that a “no fee” claim is false.

It is that the carrier must distinguish:

• program fee;
• account fee;
• payment fee;
• delinquency fee.

Translate every fee into cents per gallon

A monthly fee becomes easier to evaluate when spread across actual gallons.

Example

Owner buys:

• 1,500 gallons per month.

Card charges:

• $15 monthly account fee;
• $5 in total transaction fees.

Total monthly fees:

• $20.

Fee per gallon:

• $20 ÷ 1,500;
• approximately $0.0133.

The card needs to save more than:

• 1.33 cents per gallon

before route and payment costs.

Low-volume month

If the owner buys only:

• 400 gallons,

the same $20 becomes:

• 5 cents per gallon.

Fixed fees punish low utilization.

Multiple cards

Suppose two backup cards each cost $8 per month.

Annual backup-card cost:

• $16 × 12;
• equals $192.

The carrier should identify the emergency or discount value that justifies $192.

Compare net savings per gallon

Use:

Net savings per gallon = realistic alternative price − card price − fee per gallon − route cost per gallon

Example:

• realistic route price: $3.85;
• card price: $3.55;
• account and transaction cost: $0.03 per gallon;
• route cost: $0.06 per gallon.

Net saving:

• $3.85 − $3.55 − $0.03 − $0.06;
• equals $0.21 per gallon.

On 1,500 monthly gallons:

• $315 monthly;
• $3,780 annualized.

That is a defensible savings estimate.

Cash flow can be worth more than discount

Compare two cards.

Card A

• prepaid;
• saves $0.35 per gallon;
• requires $4,000 loaded before the week begins.

Card B

• charge account;
• saves $0.20 per gallon;
• payment due after the billing period.

At 1,000 gallons:

• Card A gross saving: $350;
• Card B gross saving: $200.

Card A saves $150 more.

Card B leaves thousands of dollars available temporarily for:

• insurance;
• repair;
• payroll;
• tolls;
• emergency.

The correct answer depends on liquidity.

The owner should not pay an excessive fuel price for financing, but should recognize that prepaid and credit products solve different problems.

Credit limit and daily operating reality

A fuel-card approval does not guarantee a usable limit.

Determine:

• total line;
• daily card limit;
• transaction limit;
• gallon limit;
• fuel-type restriction;
• merchant-category restriction;
• reset time;
• weekend funding.

Stress test

Can the card support:

• diesel price spike;
• two fills in one day;
• reefer fuel;
• emergency detour;
• replacement driver;
• temporary route change?

A limit sized to average fuel spend can fail on the most expensive operating day.

Fuel only or broader purchasing?

Some cards allow:

• diesel;
• gasoline;
• DEF;
• maintenance;
• tires;
• tolls;
• lodging;
• cash or checks.

Broader acceptance creates convenience.

It also expands misuse risk.

Owner-driver

A single owner can benefit from one controlled business-payment method.

Hired driver

A small fleet should restrict:

• merchant category;
• purchase type;
• dollar amount;
• gallons;
• time;
• location;
• cash access.

The card should require prompts such as:

• driver ID;
• unit number;
• odometer;
• PIN.

Fraud control is part of the financial return

Fuel theft can exceed the discount.

Useful controls include:

• card lock;
• purchase limits;
• driver PIN;
• unit assignment;
• odometer prompt;
• location restriction;
• product restriction;
• real-time alert;
• unusual-volume alert.

Reconcile, do not merely receive alerts

Match each purchase to:

• truck;
• driver;
• location;
• gallons;
• tank capacity;
• odometer;
• route;
• date and time.

Investigate:

• gallons above tank capacity;
• two distant purchases close together;
• fuel during maintenance downtime;
• non-fuel purchase;
• repeated round amounts;
• transaction outside route.

A card cannot prevent fraud when controls are never configured.

Loyalty programs can change the practical result

A fuel-card discount and a truck-stop loyalty program can sometimes operate together.

Confirm:

• whether points are earned;
• whether cash-price treatment applies;
• whether showers are credited;
• whether the card discount reduces rewards;
• whether the provider or driver keeps the benefit.

Value benefits conservatively

Do not count a reward the owner does not use.

A free shower has economic value when it replaces a purchase.

A point balance that expires unused has none.

Parking availability can also justify a slightly higher fuel price when it protects legal HOS planning and avoids a second stop.

Fuel-card records and IFTA

A fuel-card transaction report can become an important part of IFTA documentation.

Under the IFTA Procedures Manual, a valid retail receipt, invoice or transaction listing used to support tax-paid fuel credit should contain information including:

• purchase date;
• seller name and address or identifiable vendor code;
• quantity;
• fuel type;
• price per gallon or total price;
• vehicle identification;
• purchaser name.

The base jurisdiction controls filing and audit administration.

Test the export

Before relying on the card for tax records, export a real report and confirm it shows:

• unit number;
• location;
• date;
• gallons;
• fuel type;
• amount;
• merchant;
• jurisdiction where possible.

A fuel statement does not replace distance records

IFTA requires more than fuel purchases.

The carrier still needs reliable:

• total distance;
• jurisdiction distance;
• vehicle assignment;
• trip records;
• reconciliation.

The fuel card can support one side of the calculation.

It does not calculate a defensible return merely because the app displays an IFTA tab.

Discounts and fuel-tax price differences

The lowest pump price can reflect different state tax structures.

An owner-operator should not route solely by displayed fuel price without considering:

• IFTA tax reconciliation;
• route miles;
• truck efficiency;
• operational needs.

The price paid at the pump and the final fuel-tax obligation are related but not identical.

The dedicated IFTA article explains the calculation.

How to test a fuel card for 30 days

Do not replace the current card based only on a sales quote.

Run a measured trial.

Week 1: map availability

Record live discounted prices on regular lanes.

Compare with:

• cash price;
• current card;
• nearby competitors;
• planned stops.

Week 2: test operations

Use the card for normal purchases.

Test:

• activation;
• PIN;
• limits;
• app pricing;
• receipt;
• alerts;
• support;
• declined transaction process.

Week 3: test records

Export:

• transaction report;
• invoice;
• card statement;
• IFTA-related data.

Confirm vehicle identification and merchant detail.

Week 4: calculate economics

Add:

• gallons;
• actual card price;
• all fees;
• detour miles;
• extra time;
• loyalty value;
• payment costs.

Compare with the realistic alternative.

Do not compare against posted credit price when the alternative is cash

The baseline must be the price the carrier could actually obtain without the card.

Three owner-operator profiles

Profile 1: stable regional lanes

Best fit usually favors:

• deep network discount on repeated locations;
• strong cash-price visibility;
• low fixed fees;
• simple route planning.

A smaller network can work extremely well.

Profile 2: irregular nationwide freight

Best fit usually favors:

• broad acceptance;
• multiple discount partners;
• reliable out-of-network option;
• second card;
• strong app search.

The deepest regional discount may be less important than consistent availability.

Profile 3: new authority with tight cash

Best fit usually balances:

• discount;
• low setup cost;
• realistic funding;
• no punitive minimum;
• sufficient credit or fast ACH;
• no disruptive hold.

The cheapest diesel is not useful when the payment structure prevents the truck from fueling.

When two cards are better than one

A primary and backup card can provide:

• larger network;
• emergency acceptance;
• regional pricing advantage;
• protection during outage;
• alternative after account suspension.

The carrier should avoid:

• duplicate monthly fees;
• excess deposits;
• inconsistent reporting;
• cards used too rarely to justify the cost;
• driver confusion.

Assign roles

Example:

• Card A: primary discounted network;
• Card B: broad-acceptance backup;
• ordinary business card: emergency non-fuel use.

Drivers should know which card to use and why.

The 12 questions to ask the provider

Pricing

1. What is the final price formula?
2. Which price is used as the discount baseline?
3. Is the discount immediate or rebated?
4. Can I see live prices before fueling?

Network

5. Which locations are discount eligible?
6. What happens outside the network?
7. Are truck-lane purchases treated differently?

Fees

8. What setup, monthly, per-card and transaction fees apply?
9. What funding, late and returned-payment fees apply?
10. Can fees change after account opening?

Operations

11. What spending controls and emergency support are available?
12. Does the export contain the fuel records needed for accounting and IFTA support?

Require the answers for the exact card offer.

A practical comparison sheet

Measure	Card A	Card B	Card C
Final price on five common stops	Record	Record	Record
Usable discounted gallons	Estimate	Estimate	Estimate

The comparison should use the same:

• routes;
• gallons;
• time period;
• baseline price.

Eight mistakes that erase fuel-card savings

Choosing by maximum discount

Use final prices on actual lanes.

Ignoring route deviation

Every discount station has a travel cost.

Confusing acceptance with discount coverage

An accepted purchase can still be full price or carry a fee.

Ignoring payment fees

Card-funded account payments can be expensive.

Letting fixed fees accumulate across backup cards

Annualize every inactive-card cost.

Failing to configure controls

Discount does not compensate for unauthorized purchases.

Trusting an IFTA label without testing the export

Verify the actual transaction fields.

Paying late

One large penalty can erase months of fuel savings.

The final calculation

At the end of each month, calculate:

Gross card savings

• realistic alternative price minus card price;
• multiplied by gallons.

Then subtract:

• account fees;
• card fees;
• transaction fees;
• funding fees;
• late or returned-payment fees;
• route deviation;
• extra driver time.

Then add only rewards actually retained.

The result is:

Net fuel-card value

Track it as:

• dollars per month;
• cents per gallon;
• dollars per mile.

A card should be replaced when another tested option delivers a meaningfully better result without unacceptable payment or network risk.
