How to calculate Step Up EMI for a loan.?

A Step-Up emi is a repayment method where your EMI increases every year (or at fixed intervals). It helps you start with a lower EMI and gradually pay more as your income grows.

To calculate Step-Up EMI, you normally follow these steps:

1. Start with the base EMI

Use the normal EMI formula:

EMI=((1+r)n−1)P⋅r⋅(1+r)n​

Where:

P = Loan Amount

r = Monthly Interest Rate

n = Total Months

2. Apply the Step-Up Percentage

Decide how much the EMI will increase — for example:

5% increase every year

10% increase every two years

₹2,000 fixed increase every year

3. Recalculate outstanding balance each year

After every 12 months:

Subtract total EMIs paid

Find the new outstanding balance

Increase EMI by the step-up rate

Continue the same process until the loan closes

Simple Example

Loan: ₹20,00,000

Tenure: 20 years (240 months)

Interest: 9% annually

Step-Up: 5% increase every 12 months

Year 1: EMI = ₹17,995

Year 2: EMI = ₹17,995 × 1.05 = ₹18,894

Year 3: EMI = ₹18,894 × 1.05 = ₹19,838

…and so on, until loan is completed.
