A browser-based calculator estimates the merchant fees businesses may owe under an upcoming UPI fee rule, using payment-export files.

Landing page captured for the 2026-09-26 issue.

For: Businesses accepting UPI payments
Worth noticing: It explains that the ₹300 cap applies per payment, and shows estimates both with and without 18% GST because GST treatment is unconfirmed.

Field notes

The workflow allows files to be grouped into segments, such as separate branches or online sales, before comparing the resulting fees. The page says PhonePe exports are recognized instantly, while other bank, Paytm, or card-machine reports may need column matching. It warns that mixed UPI-and-card files count only UPI payments, and that the estimate does not cover several named payment categories.
