When you take a loan, calculating your EMI (equated monthly instalments) becomes crucial to managing your finances. But did you know there are different ways to calculate EMI? One of the most popular methods is the reducing balance method. Let us break it down in the simplest way possible, so you can understand how it works, why it is useful, and how it applies to home loans.

What is the reducing balance method?

The reducing balance method calculates interest only on the outstanding loan amount, not the original amount borrowed. This means your interest burden decreases with each EMI payment, as a part of the principal amount gets repaid every month.

Imagine this:

  • You borrow Rs. 5,00,000 as a loan.
  • Each month, you pay back some of the principal plus the interest on the remaining balance.
  • As the balance reduces, the interest you pay also reduces.
This method is especially helpful for home loans, as it minimises the overall interest you pay over the loan tenure.

Formula to calculate EMI in reducing balance method

The formula for EMI calculation is:

EMI = [P x R x (1+R)^N] / [(1+R)^N - 1]

In this formula,

  • P:is the principal amount
  • R:is the monthly interest rate
  • N:is the number of months
Let us break it down:

1. Loan amount (P): The amount you borrow from the lender. For example, Rs. 10,00,000.

2. Monthly interest rate (r): If the annual interest rate is 12%, the monthly rate will be 12%÷12=1% or 0.01.

3. Loan tenure (n): If your loan tenure is 5 years, it means 5 × 12 = 60 months.

How the reducing balance method works

Each EMI consists of two parts:

  • Principal repayment
  • Interest on outstanding loan
Let us take an example to understand this better:

  • Loan amount: Rs. 1,00,000
  • Annual interest rate: 12%
  • Tenure: 12 months
Step 1: Calculate monthly interest rate
Step 2: Calculate EMI using the formula.
Step 3: Understand the breakdown.

In the first month, the interest is calculated on Rs. 1,00,000. But in the second month, it is calculated on a reduced balance because you have already paid back part of the principal. This is how the reducing balance method ensures you pay less interest over time.

Benefits of the reducing balance method

  • Lower total interest: You save money as the interest reduces with every payment.
  • Encourages early repayment: The sooner you repay, the less interest you will pay overall.
  • Perfect for long-term loans: This method is ideal for home loans, as the savings on interest can be significant over a longer tenure.

Comparing flat rate vs. reducing balance

It is easy to confuse the reducing balance method with the flat rate method. Let us compare:

FeatureFlat rate methodReducing balance method
Interest calculationOn the entire loan amountOn the outstanding balance
EMI amountFixed throughoutReduces over time
Overall interestHigherLower


For example, if you take a Rs. 5,00,000 loan for 5 years at a 10% interest rate, you would pay significantly less interest with the reducing balance method than with the flat rate method.

Why it matters for home loans

Home loans typically involve large amounts and long tenures, making the reducing balance method a smart choice. With this method, you are not just paying off the loan; you are saving on interest every step of the way. You can use an EMI calculator to estimate your monthly payments.

Frequently asked questions

How is EMI calculated on reducing the balance method?
EMI in the reducing balance method is calculated based on the outstanding loan balance after each payment. Interest is charged only on the remaining amount, ensuring that both the interest and EMI decrease over time as the principal is repaid.

How to calculate monthly home loan interest rates on reducing balance methods?
To calculate monthly interest, divide the annual interest rate by 12. Then, multiply this monthly rate by the outstanding loan balance. The interest amount decreases each month as the principal reduces through EMI payments.

Is fixed rate higher than reducing balance?
Yes, fixed-rate methods usually result in higher interest payments compared to reducing balance methods. Fixed-rate calculates interest on the entire loan amount throughout the tenure, while reducing balance charges interest only on the outstanding balance.

What is the formula for calculating home loan EMI?
The formula is: EMI = [P × R × (1+R)^N] / [(1+R)^N - 1], where P = principal, R = monthly interest rate, and N = loan tenure in months. This formula works for the reducing balance method.
