How to Use This Calculator
Convert to EMI tab
Enter your credit card outstanding amount, the bank's EMI conversion interest rate, and choose a tenure (6/9/12 months). The calculator shows your monthly EMI, total interest, processing fee with GST, and total cost. Use this to check if EMI conversion makes sense for your bill.
EMI vs Minimum Payment tab
Enter your outstanding balance and compare two paths: paying only the minimum due (5%) at revolving interest (36-42% p.a.) versus converting to a 12-month EMI at 15% p.a. See the total interest difference, time to clear debt, and how much you save by choosing EMI.
No-Cost EMI Reality Check tab
Enter the product MRP and the processing fee per instalment (check the fine print). The calculator reveals the effective annual interest rate hidden inside "No-Cost EMI" offers. Most no-cost EMIs have a 5-12% effective rate once processing fees and GST are factored in.

The Formula
Credit card EMI is calculated using the standard reducing balance EMI formula:
EMI = P × r × (1 + r)n / [(1 + r)n − 1]
Where:
P = Principal (outstanding amount)
r = Monthly interest rate (annual rate / 12 / 100)
n = Number of months (EMI tenure)
EMI = Equated Monthly Instalment
Total Interest:
Total Interest = (EMI × n) − P
Total Cost:
Total Cost = (EMI × n) + Processing Fee + GST on Fee
No-Cost EMI Effective Rate:
Effective Rate = (Total Fees with GST / MRP) × (12 / Tenure) × 100
Minimum Payment Simulation:
Each month: Interest = Balance × Monthly Rate
Payment = max(Balance × Min%, &rupee;100)
New Balance = Balance + Interest − Payment
Repeated until balance reaches zero.
Revolving credit interest (36-42% p.a.) is charged on the entire outstanding from the transaction date. Unlike EMI where interest is on reducing balance, revolving interest makes minimum payments extremely expensive over time.
Example
Rahul — Mumbai IT professional, &rupee;1,00,000 credit card bill
Rahul has a &rupee;1,00,000 outstanding on his credit card after a medical emergency. He needs to decide: pay minimum 5% each month, or convert to 12-month EMI at 15% p.a.?
Step 1: Minimum payment path (5% at 42% p.a.)
Step 2: EMI conversion path (12 months at 15% p.a.)
Step 3: The verdict
By converting to EMI, Rahul saves over &rupee;73,000 in interest and clears his debt in 12 months instead of 44. The structured EMI also protects his credit score, which would have been damaged by revolving credit.
