Equated Monthly Instalments (EMI) play a crucial role in loan repayment. The reducing balance method is a preferred choice for calculating EMIs, as it reduces interest costs over time. This method applies interest only on the outstanding principal, ensuring that borrowers pay less interest with each payment.
This article will explain how EMI is calculated in the reducing balance method. It will cover the concept, formula, step-by-step calculation using Excel, an example, and a comparison with the fixed interest method.
What is the reducing balance method and how does it work?
The reducing balance method is a way to calculate interest where the interest amount decreases over time. Instead of charging interest on the entire loan amount, it is applied only to the outstanding principal after each EMI payment.
For instance, in a home loan, if Rs. 10,00,000 is borrowed at a 10% annual interest rate for 5 years, the interest for the first month is charged on Rs. 10,00,000. In the second month, after repaying part of the principal, interest is charged on the remaining balance. This continues until the loan is fully repaid.
This method benefits borrowers as they pay lower total interest over time compared to a flat-rate method.
Planning to take a home loan and want to benefit from lower interest costs? Understanding EMI calculations is the first step, but finding the right loan offer is equally important. Check your eligibility for a home loan from Bajaj Finserv with competitive interest rates starting at 7.45%* p.a and flexible repayment tenure up to 32 years.

What is the formula for EMI calculation in the reducing balance method?
The formula to calculate EMI using the reducing balance method is:
EMI = (P x R x (1+R)^N) / ((1+R)^N - 1)
Where:
- P = Loan principal (amount borrowed)
- R = Monthly interest rate (Annual interest rate / 12)
- N = Loan tenure (in months)
Example calculation
| Parameter | Value |
| Principal (P) | Rs. 10,00,000 |
| Annual interest rate | 10% |
| Monthly interest rate | 0.0083 (10%/12) |
| Loan tenure (N) | 60 months |
Using this formula, the EMI for the above example can be calculated
While manual calculations help you understand the EMI structure, getting pre-approved for your home loan can simplify your property purchase journey.

How to calculate EMI in the reducing balance method using Excel?
Calculating EMI in Excel is a simple and efficient process. Follow these steps:
1. Open Excel and enter the following values in separate cells:
- A1: Loan Principal (Rs. 10,00,000)
- A2: Annual Interest Rate (10%)
- A3: Loan Tenure in Months (60)
2. Calculate the Monthly Interest Rate:
- In cell A4, enter =A2/12/100 to get the monthly rate.
3. Use the PMT function to calculate EMI:
- In cell A5, enter =PMT(A4,A3,-A1).
4. Press enter and the EMI amount will be displayed.
Using Excel allows users to adjust loan parameters and see real-time changes in EMI calculations.
How to calculate EMI using the reducing balance method?
To manually calculate EMI using the reducing balance method, follow these steps:
- Identify loan details: Gather loan amount, interest rate, and tenure.
- Calculate monthly interest rate: Convert annual interest into a monthly rate by dividing it by 12.
- Apply the EMI formula: Use EMI = (P x R x (1+R)^N) / ((1+R)^N - 1).
- Understand payment structure: Each EMI contains a portion for principal repayment and interest.
Example calculation
For a home loan EMI calculator, consider:
- Loan Amount = Rs. 5,00,000
- Interest Rate = 10%
- Tenure = 5 years
The monthly interest rate would be 0.0083, and using the formula, EMI can be calculated.
Reducing balance method vs fixed interest: Which one is better?
| Feature | Reducing balance method | Fixed interest method |
| Interest calculation | On outstanding loan balance | On the full loan amount |
| Total interest paid | Lower | Higher |
| EMI amount | Decreases over time | Fixed throughout the tenure |
| Best for | Long-term loans (home loans) | Short-term, small loans |
