3,050 is the example result. Read it using the units and relationship stated below.
Payment Processing Fee uses processed sales, percentage fee (%), fixed fee per transaction.
Keeping timing visible in cash decisions
For payment processing fee, the relationship is Result = [Processed sales] × [Percentage fee (%)] ÷ 100 + [Fixed fee per transaction] × [Transactions]. The amount depends on the supplied processed sales, percentage fee (%), rather than a live market price or a value imported from another record. Profit does not state when money reaches the bank. Receivables, supplier payments and inventory can absorb cash while sales remain healthy. A cash comparison needs the payment window and outstanding balance, not only the invoice total.
What the model includes
Result = [Processed sales] × [Percentage fee (%)] ÷ 100 + [Fixed fee per transaction] × [Transactions] Record whether amounts include tax, credit notes or disputed balances. Where a model converts annual flows into days, keep the balance and flow definitions consistent. Supplier terms and collection delays may move independently. Use the result to identify the next collection or payment question. A financing decision also needs contractual fees, settlement timing and repayment terms that may sit outside this model.
Example with the supplied inputs
Processed sales: 100000; Percentage fee (%): 2.9; Fixed fee per transaction: 0.3; Transactions: 500. Result: 3,050. The values are illustrative.
Compare one changed input
Processed sales changes from 100000 to 110000. The result becomes 3,340. All other inputs remain fixed.
Calculation rule
Result = [Processed sales] × [Percentage fee (%)] ÷ 100 + [Fixed fee per transaction] × [Transactions]
Inputs and output
| Input | Example value | Entry convention |
|---|---|---|
| Processed sales | 100000 | Use the source quantity represented by processed sales. Keep the counted population fixed and avoid mixing a unit value with a period total. |
| Percentage fee (%) | 2.9 | Enter percentage fee (%) on the percentage scale used in the formula (20 means 20%, not 0.20). Keep its base and reporting period consistent with the other inputs. |
| Fixed fee per transaction | 0.3 | Use the source quantity represented by fixed fee per transaction. Keep the counted population fixed and avoid mixing a unit value with a period total. |
| Transactions | 500 | Use the source quantity represented by transactions. Keep the counted population fixed and avoid mixing a unit value with a period total. |
Output: 3,050 is the example result. Read it using the units and relationship stated below. Use the formula to distinguish a cash amount, count, percentage or ratio.
How to use the page
Collect the inputs
Gather Processed sales, Percentage fee (%), Fixed fee per transaction. Use one period and the units shown in the form.
Run the calculation
Enter the values and select the action. The calculation rule above explains how the inputs produce the result.
Compare a scenario
Change Processed sales on its own, keeping the other inputs fixed. Read both results before changing another assumption.
Worked example
With the example inputs listed above, the result is 3,050.
Change Processed sales from 100000 to 110000 while keeping every other value fixed. The result becomes 3,340. This comparison isolates that input; it does not forecast how other variables will respond.
Check the stated formula, units and limits before using the result in a decision.
Keep the displayed formula, input units and model scope with the result. Corrections or questions can be sent through the request section on this page.
