Formula Used
Total percentage rate = base percentage fee + international rate + conversion rate + platform rate.
Fee before tax = gross charge × total percentage rate + total fixed fee.
Tax on fees = fee before tax × tax rate.
Total fee = fee before tax + tax on fees.
Net payout = gross charge − total fee.
Target gross = (target net + fixed fee × tax multiplier) ÷ (1 − percentage rate × tax multiplier).
Final batch net = batch net before adjustments − refunds − dispute costs.

Why This Calculator Helps
A processing fee looks small at first. It can still change profit quickly. This calculator helps you compare the amount charged, the fee removed, and the payout kept after each payment. It is useful for store owners, freelancers, agencies, and donation pages.
Better Fee Planning
Many payment costs use a percentage plus a fixed charge. Extra settings can also matter. International cards may add a higher percentage. Currency conversion may add another percentage. Platforms can add application fees. Tax may apply to fees in some places. This tool lets you enter each part separately. You can keep the default values, or replace them with your own account terms.
Net Payout Insight
The net payout is the gross charge minus all selected fee parts. The calculator also shows the effective fee rate. This number helps you understand the real cost of a transaction. A low ticket price can have a higher effective rate because the fixed fee is larger compared with the sale amount.
Gross Up Pricing
Some users need to know what to charge so a target amount remains after fees. The target net mode solves that problem. Enter the amount you need to keep. The calculator estimates the gross customer charge required to reach it. This is helpful when pricing invoices, deposits, subscriptions, tickets, and service packages.
Batch Forecasting
One payment is only part of the story. A month may include many payments. Use the quantity field to estimate batch totals. You can also add refund and dispute assumptions. Refunds reduce retained revenue. Dispute fees reduce the final net amount. These fields help build a safer forecast.
Reporting and Records
After submitting the form, the result appears below the header. You can download the summary as a CSV file. You can also create a simple PDF report. These exports are useful for records, client planning, and quick comparisons.
Use With Care
This calculator is an estimate. Actual charges can vary by country, card type, payment method, connected account setup, custom pricing, taxes, and account settings. Always compare the result with your dashboard or pricing agreement before final billing decisions. Review saved reports often. Small pricing edits can protect margins across many routine payments each week.
FAQs
What does this calculator estimate?
It estimates processing fees, net payout, effective fee rate, batch totals, refunds, disputes, and the gross charge needed for a target net amount.
Can I change the default fee values?
Yes. The percentage fee, fixed fee, international rate, conversion rate, platform rate, and tax rate are editable fields.
What is target net payout mode?
Target net mode starts with the amount you want to keep. It then estimates the gross customer charge needed after fees.
Does the calculator include refunds?
Yes. Enter a refund amount per transaction. The tool subtracts refunds from the final estimated batch net.
Does the calculator include dispute costs?
Yes. Add the expected dispute count and dispute fee. The tool subtracts that total from the final batch result.
What is the effective fee rate?
It is the total fee divided by the gross charge. It shows the real percentage cost of the transaction.
Why can small payments have higher fee impact?
The fixed fee is a larger share of a small sale. That can raise the effective fee rate.
Are the results final billing numbers?
No. They are estimates. Actual fees may vary by region, card type, payment method, taxes, account terms, and custom pricing.
