The 25 Basis Point Calculator: Exactly How Your EMI Changes on Every RBI Move
Introduction to the 25 Basis Point Calculator
Consider a homeowner in Mumbai with a ₹50 lakh home loan from SBI at 7.5% interest for 20 years. If the RBI raises the repo rate by 25 basis points (bps), the new interest rate becomes 7.75%. Using the NestSaver EMI Calculator, we find the EMI increases by approximately ₹552, from ₹43,391 to ₹43,943. But how does this change for different loan amounts and tenures?
Understanding the Impact of RBI Moves on EMI
The impact of a 25 bps rate hike on EMI varies significantly with loan amount and tenure. For longer tenures, the EMI increase per rupee is smaller, but the total interest paid over the loan period increases more substantially. To illustrate, let's calculate the EMI change for a ₹50 lakh loan at 7.5% interest for 20 years, compared to 25 years.
Assuming a 20-year tenure at 7.5%, the EMI is ₹43,391. If the rate increases to 7.75%, the EMI becomes ₹43,943, an increase of ₹552. For a 25-year tenure at 7.5%, the EMI is ₹37,493. At 7.75%, the EMI is ₹37,955, an increase of ₹462.
How we calculated this: We used the formula for EMI calculation, M = P[r(1+r)^n]/[(1+r)^n – 1], where M is the monthly payment, P is the principal loan amount, r is the monthly interest rate, and n is the number of payments. We assumed a monthly interest rate of 7.5%/12 = 0.00625 for the initial calculation and 7.75%/12 = 0.006458 for the increased rate calculation.

| Loan Amount | Tenure (Years) | Initial EMI (₹) | EMI after 25 bps hike (₹) | EMI Increase (₹) | Total Interest Increase (₹) |
|---|---|---|---|---|---|
| 30L | 15 | 26,143 | 26,449 | 306 | 34,119 |

| 60L | 30 | 39,443 | 39,877 | 434 | 123,211 |
| 75L | 20 | 49,318 | 49,851 | 533 | 95,356 |
| 1Cr | 25 | 62,658 | 63,203 | 545 | 186,914 |
Why EMI Change on Longer Tenure is Smaller but Total Interest Impact is Larger
The reason for the smaller EMI increase on longer tenures is due to the way interest is calculated and amortized over the loan period. For longer tenures, a larger portion of the initial payments goes towards interest, rather than principal. Therefore, the increase in interest rate has a more significant impact on the total interest paid over the life of the loan, even if the EMI increase is smaller.
Current Scenario and Future Outlook
Given the current RBI repo rate of 5.25% and home loan rates ranging from 7.5% to 7.85%, borrowers should be aware of the potential impact of future rate hikes. The RBI Rate Hike Impact by City tool can help homeowners understand how changes in interest rates may affect their EMI and total interest paid.
