Practical Worked Example

A cardholder owes Rs 1,00,000 on a card at 36% APR and pays only the 5% minimum payment each month.

01.Month 1: Pay Rs 5,000 (Rs 3,000 interest + Rs 2,000 principal).
02.As the balance decreases, the 5% minimum payment drops, slowing principal reduction to a crawl.
03.Total Payoff Timeline = 14.8 Years (178 Months).
04.Total Interest Paid = Rs 1,42,800 on a Rs 1,00,000 purchase.
14.8 Years | Rs 1,42,800 InterestPaying only the minimum allows the credit card issuer to extract 140%+ of your principal in pure interest.
