Fuel Card Fee Calculator
Estimate card fees
Add monthly, transaction and other recurring fees.
When to Use This Calculator
Use this calculator when you have a published fee schedule or a written quote and want to convert account fees into monthly cost, annual cost and effective cost per gallon. This helps compare a low advertised discount against the fees needed to use the account.
Input Fields
| Field | What to enter | What to verify |
|---|---|---|
| Monthly fee | Recurring account, card, plan or service fee. | Whether it is per account, per truck, per card or per plan. |
| Transaction fee | Fee charged per fuel purchase or card authorization. | Whether the fee applies in-network, out-of-network or only in certain cases. |
| Fuel transactions | Expected number of fuel purchases per month. | Use expected stops, not only monthly gallons. |
| Other monthly fees | Known recurring service, statement or program fees. | Check for paper statement, late payment, returned ACH or replacement card fees separately. |
| Gallons per month | Expected diesel gallons for the same month. | Use the same gallon estimate you use for savings comparisons. |
Formula
Monthly estimated fees = monthly fee + transaction fee × fuel transactions per month + other monthly fees. Effective fee per gallon = monthly estimated fees ÷ gallons per month.
How to Read the Result
The effective fee per gallon can be compared against a stated cents-per-gallon discount. For example, if a card appears to save 15 cents per gallon but has an estimated fee load of 4 cents per gallon, the net value is closer to 11 cents before considering network fit.
This calculator does not include unknown fees. If the provider does not clearly publish a fee, treat it as a provider-confirmation item before applying. Related reading: fuel card fees explained and hidden fuel card fees.
Common Mistakes
Do not treat an unpublished fee as zero. A fee that is missing from a public page should be listed as unknown until the provider confirms the current schedule. Also avoid using monthly gallons from a busy season if the card will be used year-round by a one-truck or seasonal operation.
Transaction count can matter as much as gallons. A driver who tops off frequently can pay more per gallon in swipe fees than a driver who buys larger fills, even if both use the same monthly fuel volume.
Records to Keep With the Estimate
Keep the fee schedule, plan name, billing cycle, transaction count assumption and gallon estimate with the result. If a provider waives a monthly fee after a minimum volume, save that condition and recalculate when expected gallons change.
