How to Calculate

How to calculate credit card installments: Interest-free: total amount divided by the number of months With interest: equal principal & interest (EMI) method PMT = P × r × (1+r)^n / ((1+r)^n − 1) P = total amount, r = monthly rate, n = number of months Typically 2–3 months interest-free installments are offered; beyond that, the card issuer's annual rate applies.
