About this app
Surcharge Calculator is a dual pricing calculator for merchants, cashiers, and POS operators. Enter any sale amount and instantly see the total with taxes, service charges, surcharges, and fees.
Dual pricing, made simple
Show the cash price and the card price side by side. Dual pricing lets you recover credit card processing costs while staying transparent with every customer.
Surcharges, service charges, and fees
Set your own surcharge percentage and tax rate. The calculator applies taxes first, then fees, so you can quote:
• Total — the amount you entered
• Total + Taxes — amount after sales tax
• Total + Taxes & Fees — final amount with surcharge or service charge
Built for the counter
Large keypad, clear totals, and a layout that works on phones and tablets. Perfect for retail, restaurants, salons, auto shops, and any business that adds a card surcharge, convenience fee, or service charge.
