What is Personal Loan Interest and Why Does It Matter?
When you take a loan, the bank or lender charges interest on the borrowed amount. The interest is calculated based on the loan amount, tenure, and rate of interest. Knowing how to calculate personal loan interest allows you to:
- Estimate your total repayment amount – By understanding how to calculate the interest on a personal loan, you will be able to estimate the total repayment amount that will be made over the tenure of the loan. This will include both the principal amount and the interest.
- Compare offers from different lenders – In order to understand which lender provides a personal loan according to your needs and requirements, it is important to compare the interest rate, loan repayment, tenure, and choose the one that provides you with better offers.
- Plan monthly finances effectively – Once you calculate your personal loan amount, you will know the exact monthly amount (EMI) to be repaid. This will help you in easy management of your finances and save you from last minute trouble.
- Avoid hidden costs – Calculating personal loan amounts will help you in understanding the unnecessary high costs, hidden charges or unfavourable loan terms. This awareness protects you from unexpected financial strain during the repayment period.
Methods to Calculate Personal Loan Interest
Difference between the Flat Rate Method and the Reducing Rate Method:
| Flat Rate Method | Reducing Rate Method |
| Interest rate is calculated for the full loan amount for the entire tenure | Interest is calculated only on the outstanding principal after each EMI |
| Formula: (Loan Amount × Interest Rate × Tenure) ÷ 100 | EMI = [P × R × (1+R)^N] / [(1+R)^N – 1] |
| Principal remains the same throughout the loan tenure | Principal reduces with every EMI payment |
| Overall higher interest cost | Overall lower interest cost |
| EMIs are lower but include higher interest | EMIs reflect decreasing interest over time |
| Less transparent and can be misleading | More transparent and borrower friendly |
| Rarely used today for personal loans | Commonly used by banks and NBFCs |
| Short-term or small-ticket loans | Most personal loans and long-term loans |
1. Flat Rate Method Example:
If you borrow ₹2,00,000 at 10% interest for 3 years:
Interest = (200000 × 10 × 3) / 100 = ₹60,000
Total Repayment = ₹2,60,000
This method usually results in a higher cost compared to the reducing balance method.
2. Reducing Balance Method Example:
For a loan of ₹2,00,000 at 10% interest for 36 months:
- Monthly Interest = 10 ÷ 12 ÷ 100 = 0.0083
- EMI = ₹6,462 approx.
- Total Repayment = ₹2,32,632 (includes interest ₹32,632)
This method benefits borrowers as the interest rate reduces over time.

Frequently Asked Questions (FAQs):
How to calculate interest rate on a personal loan?
A personal loan interest rate is calculated based on the loan amount, interest rate and tenure. Most lenders prefer to follow the reducing balance method, wherein the interest is charged only on the outstanding principal amount. You can calculate it manually by using the EMI formula or use an online personal loan EMI calculator.
What is the difference between flat rate and reducing balance method?
Under the flat rate method, the interest is calculated on the entire amount for the entire term, thereby resulting in higher overall interest. On the other hand, the reducing balance system calculates the interest on the outstanding amount after each EMI, thereby making it more cost-effective.
Which method is used for personal loan EMI calculation?
The majority of banks and NBFCs in India follow the reducing balance method for calculating the personal loan EMI. This will help in reducing the interest as you pay off the principal amount, thereby reducing the total interest paid during the loan period.
Can part pre-payment reduce personal loan interest?
Yes, by making part-prepayments, the outstanding principal amount will decrease, and consequently, the interest paid in the future EMIs will be lower. This may help you in reducing the overall interest burden or may result in a shorter loan period, depending on the lender’s terms.
What is the RBI rate of interest for personal loan?
The RBI does not set the interest rates for personal loans. The interest rates are determined by banks and NBFCs depending on various factors such as credit scores, income, and repayment history, which are normally between 10% and 24% per annum.
Conclusion
With the knowledge of calculating the interest on personal loans, you are in complete control of your lending and borrowing activities and can avoid unnecessary stress. When you know how the interest is calculated, you will be able to see clearly how much you will be repaying as interest over the loan period and how it fits into your budget. It is especially important to understand the difference between the flat rate system and the reducing balance system since it directly affects the amount of interest you will be paying. Although the flat rates may seem lower at first, the reducing balance calculations are generally more economical.
Personal loan EMI calculators also make it easier for you to calculate your EMI. These calculators provide you with instant and accurate calculations of your EMI based on the loan amount, interest rate, and tenure, so you can compare different loan options with confidence.
