Quick answer
Pay-later plans look free, but a fixed fee turns into a yearly cost. Splitting ₹6,000 into 3 monthly payments with a ₹150 fee means ₹2,050 a month and ₹6,150 in total. That ₹150 works out to about 16% a year, close to a credit card EMI. Late fees add more, and missed payments can hurt your credit score.
How to use this calculator
- Enter the purchase amount.
- Pick the number of monthly payments in the plan.
- Add every fee shown at checkout, plus the late fee from the terms.
Formula
Instalment = (amount + fees) ÷ number of payments
Effective yearly cost = the yearly rate at which the instalments equal the purchase amount (monthly rate compounded over 12 months)
Fees and terms vary by provider. Read the plan details before you confirm.
