Illustrative example inputs
These starting values show how the math works. They are not industry averages, customer results or a quote.
| Input | Example value |
|---|---|
Original card sales before refunds Same cohort and accounting period. Exclude taxes and unrelated cash sales in this simplified example. | $50,000.00 |
Revenue reversed by completed refunds Only revenue belonging to the entered original sales, not unrelated prior-period refunds. | $5,000.00 |
All original processing expense Already included in the baseline profit. Do not subtract it again in the profit bridge. | $1,500.00 |
Original fees attributable to refunded sales Verified transaction-level amount, not an assumed proportional share of monthly fees. | $150.00 |
Confirmed original-fee credits Only credits actually supported by the agreement and records. An unknown refund-credit policy is not zero. | $0.00 |
New fees for processing the refunds Separate new charges, excluding original fees that were retained. | $25.00 |
Baseline profit before these refunds Includes the original revenue, associated costs and original processing fees. | $8,000.00 |
Recognized reversal of associated job costs Same-period expense reversal confirmed with the bookkeeper. A returned part or supplier cash receipt is not automatically a profit adjustment. | $2,000.00 |
Additional nonpayment return costs Separate restocking, return handling or other new costs not already counted. | $100.00 |
Example results
| Measure | Result |
|---|---|
Revenue after entered refunds | $45,000.00 |
Payment costs attached to the refunded sales Attributable original fees − actual fee credits + new refund fees. | $175.00 |
Complete processing expense after refund adjustments | $1,525.00 |
Profit after the refund scenario | $4,875.00 |
Calculation detail
| Measure | Result |
|---|---|
| Profit change from the refund scenario | -$3,125.00 |
| Processing expense divided by original card sales | 3.05% |
| Processing expense divided by revenue after refunds | 3.39% |
| Refunded share of original card revenue | 10% |
Model assumptions
- Starting figures are fictional planning examples, not a quote, verified outcome or small-business margin benchmark.
- This is a matched-cohort same-period management scenario. Do not mix prior-period refunds with current sales without an accountant-approved reconciliation.
- Fee credits and new refund charges are entered from actual terms and records. The fictional zero credit and $25 charge are not BlueFinch pricing or a universal provider policy.
- Original processing fees are already deducted in baseline profit. Only actual fee credits and new charges change that expense in the bridge.
- The total expense divided by post-refund revenue is a cost ratio, not evidence that a processor increased its contractual rate.
Read alongside these results
- Negative differences remain visible. A negative profit denominator gives a signed mathematical ratio, not a share of positive profit. Zero denominators are unavailable.
- A retained processing expense does not determine what the customer is legally owed. Confirm the customer refund separately.

A refund doesn’t automatically give you back the fee for the original card sale. The refund and the fee credit are separate entries. If the provider keeps the original fee, your shop still pays to process a sale even when some or all of its revenue is reversed. Track that expense separately from the money you owe the customer.
Stripe says its original processing fees aren’t returned, and refunds after successful payment might incur a fee. That’s one provider’s documented example, not a rule for every BlueFinch account. Read your own written terms and check the actual fee records. If the refund-credit rule is unknown, leave it unresolved. Don’t turn it into zero in a savings estimate.

PPF kit returns: reconcile supplier credit and card costs
Reconcile a returned PPF kit from supplier credit to customer correction. Use the ledger to keep retained processing costs and refund status separate.
Check your own costs: calculate your effective processing rate or upload a merchant statement for analysis.
Keep the refunded sales and original charges together
Start with completed sales and the refunds tied to those same sales. In this fictional example, original card revenue is $50,000, and $5,000 is reversed later in the same accounting period. The original processing expense is $1,500. Transaction records show $150 of that expense came from the sales being refunded. Enter that amount from the evidence, not a monthly average.
A refund issued this month for a sale booked last year needs a different accounting-period reconciliation. Don’t drop that older refund into this month’s sales denominator without explaining why. The IRS identifies period-specific income statements as a reason to keep reliable records. Keep the original sale reference, refund reference, and fee-credit reference in the approved business system. Use aggregate totals only in this public calculator.

Count retained fees without charging the business twice
Keep those two totals separate. The refunded jobs have $150 in original fees and $25 in new charges, with no fee credit. That puts their payment costs at $175. Across all sales, add just the new $25 to the original $1,500 bill. The total is $1,525, since the $150 was already on that original bill.
Change the fee-credit field only when your account records back it up. If a verified $100 credit arrives, the refund-related payment cost drops to $75, and total processing expense drops to $1,425. Keep a one-time provider goodwill credit separate from any contractual refund-fee policy. The merchant statement analyzer helps trace assessed fees, but your agreement and transaction records establish the amount you should enter.

A higher cost ratio does not prove a rate increase
After the $5,000 revenue reversal, $45,000 remains. Processing cost is $1,525: 3.05% of the original $50,000, but about 3.39% of the remaining $45,000. Those percentages use different denominators, so that bigger second number doesn’t prove the processor raised its contractual rate. Refunds shrank the revenue base while much of the cost stayed put.
If all entered revenue is reversed, the post-refund ratio is unavailable because the denominator is zero. The retained dollar cost still matters. The calculator keeps it visible instead of forcing a misleading percentage. Use this view to compare periods with similar refund treatment. Label whether a report divides fees by original card sales or sales after refunds.

Separate the revenue reversal from the related cost reversal
Say profit before refunds was $8,000, after the original $1,500 processing expense. Reverse $5,000 in revenue. Assume the bookkeeper also recognizes a $2,000 reversal of associated job costs in the same period. With no fee credit, there are $25 in new refund fees and $100 in other return costs. The modeled result is $4,875. Don’t subtract the original processing expense again.
A returned part, supplier credit, or inventory adjustment doesn’t automatically reverse the expense in the same period. Confirm that treatment with the person keeping the books. Use the Books workflow to review the source records before posting an adjustment. Customer entitlement is a separate issue, covered by the dual-pricing refund guide. This calculation shows the cost left after the approved refund. It does not give you permission to deduct that cost from the customer’s money.
