We learnt recently from two excellent articles by the MileLion that the advertised MPD which banks advertise is usually not what you’ll get after the bank rounding formulas are applied to your total spend.
I’ll like to share that WhatCard now shows the effective MPD that you’re getting when you key in the amount spent for a particular merchant.
Hope everyone finds this helpful and be sure to report any bugs you come across to us 
Many thanks to the MileLion for allowing us to copy the bank rounding formulas that he has figured out.
