How this is calculated
Method and background

How this is calculated

The fee is a percentage plus a flat amount, and tax applies to the total. A quoted two percent on a small transaction can land near five once a three rupee flat fee and eighteen percent tax are added, which is why low-value businesses feel gateway costs far more than the headline suggests. The effective rate shown here is the number to compare between providers.

Frequently asked questions

Why is my effective rate above the quoted one?
The flat fee per transaction and the tax on the fee. On small tickets the flat component dominates, which is why the effective rate falls as ticket size rises.
