FAQ
How do I calculate credit card fees on an invoice?
Multiply the invoice amount by the card percentage rate, add the fixed per-invoice fee, then multiply by the number of card-paid invoices if you want a monthly estimate.
Can I add credit card fees to an invoice?
Sometimes, but rules vary by processor, card network, location, and contract. Confirm the rules before adding a surcharge or fee line item.
Should I absorb invoice card fees?
It depends on margin, client expectations, and payment speed. Compare the fee against ACH, check, wire, and the value of getting paid faster.
Should I use this or the reverse calculator?
