Own a shop? (and what your customers end up paying)

The fee lands on you, not on them. This works out what it costs you a month, and how much of it ends up in your prices.

This MDR is not live yet. MDR starts in 22 days.
You would pay₹472P2M after 3 months

The ₹1,00,000 a month line decides everything.

Only those bills carry a fee, so this is their average, not your overall one.

An average cannot tell us this. A ₹2,500 average could be every bill at ₹2,500, or half at ₹500 and half at ₹4,500. Only this share decides what you pay.

This bites only after 3 straight months over the line. MDR is expected to carry 18% GST on top, and a GST-registered merchant can claim that back as input tax credit, so the real cost is closer to the MDR alone.

The 18% is not in NPCI’s FAQ. It is what press reporting expects to apply to MDR. Treat the fee alone as the firm number.
