Payment Surcharge Calculator

Calculation Breakdown
*Effective fee rate = (gateway fee ÷ amount charged to payer) × 100. This calculator is for estimation only; actual gateway charges may vary.
What Is a Payment Surcharge?
A payment surcharge is an additional fee added to a transaction to help cover costs charged by payment providers (such as Stripe, PayPal, Square, and banks). These fees usually include:
- A percentage fee (e.g., 1.75%)
- A fixed transaction charge (e.g., $0.30 per payment)
Payment surcharges are often used by businesses, clubs, associations, and organisations to avoid losing money when accepting card payments or online transactions.
Depending on policy or preference, you may choose to:
- Pass on the fee to the customer (they pay the extra cost)
- Absorb the fee (the business covers it and receives less after fees)

FAQs
Why do businesses apply surcharges?
Businesses apply surcharges to recover the costs associated with accepting specific payment methods. Processing fees can vary depending on the card type or provider, and applying a surcharge allows businesses to avoid absorbing these expenses.
Is charging a payment surcharge legal?
Legality depends on the region. In many places, surcharges are allowed but must be clearly disclosed and limited to the actual cost of processing. Some countries or states may prohibit or restrict surcharges on certain payment types.
Which payment methods are commonly surcharged?
Credit cards, some debit cards, international cards, and digital wallet payments may incur surcharges. Payments like bank transfers, direct debit, and cash typically do not include surcharges.
How should surcharges be displayed to customers?
Surcharges must be clearly shown before payment is completed. The fee should also appear as a separate line item on receipts or invoices so customers understand the amount and reason for the additional charge.
