RBI repo rate cut: Prepay your home loan now to save interest outgo; here’s how

Cheer for loan borrowers! The latest repo rate cut by the Reserve Bank of India (RBI) has brought additional relief to borrowers, especially home loan customers with long-term loans. With the repo rate reduced by another 25 basis points, the fourth cut this year which takes the cumulative reduction in 2025 to a hefty 125 basis points, banks have begun passing on the benefit. Lending rates linked to external benchmarks and repo rates have come down across major lenders, making home loans and other retail loans cheaper for both new and existing borrowers.

Lower EMIs are welcome, but they should not distract borrowers from a more fundamental truth about debt: the real cost of a loan lies not in the monthly instalment, but in the total interest paid over its lifetime. And that cost rises sharply the longer the tenure stretches.


Even after the recent cuts, most home loans are priced around 7.9-8.2%. That is significantly higher than what savers earn on fixed deposits, small savings schemes or most other fixed income instruments today, especially on a post-tax basis. In other words, many borrowers are simultaneously paying a higher rate on their loans while earning a lower rate on their investments. It’s a clear case of negative arbitrage.

This makes a strong case for retiring high-cost and long-term loans as early as possible, particularly for borrowers who have surplus funds in fixed income instruments. Prepaying a home loan is not just about emotional comfort or becoming debt-free; it is a sound financial decision grounded in simple arithmetic. Every rupee used to reduce the outstanding loan saves future interest at the loan rate, year after year. Effectively, prepayment delivers a guaranteed, risk-free return equal to the loan interest rate, which is typically around 8% today.

It is hard to find any fixed income investment that can match this return after tax. For someone in the higher tax brackets, a fixed deposit yielding 6.5% before tax translates into barely 4.5-4.8% post tax. Against this, prepaying a home loan offers a far superior outcome, with zero volatility and no reinvestment risk.

The argument becomes even stronger for borrowers opting for the new income tax regime. Under the new regime, interest paid on a self-occupied home loan does not qualify for any deduction. The long-standing tax shield that once softened the burden of home loan interest has effectively disappeared. Without tax benefits, the logic of carrying a long-tenure loan weakens considerably.

Another often overlooked aspect is how loans are structured. In the early years of a long-tenure loan, a large portion of the EMI goes towards interest rather than principal repayment. This means borrowers pay heavily upfront but reduce their outstanding balance very slowly. By prepaying early in the loan cycle, borrowers attack the interest component at its most expensive stage, shortening the tenure and sharply reducing the total interest outgo.

Many borrowers hesitate to prepay because they prefer liquidity or believe they can “earn more” by investing elsewhere. But this assumption rarely holds true for fixed income investments, especially after tax. Liquidity concerns can be addressed by retaining an adequate emergency fund, while surplus money beyond that is usually better deployed towards loan reduction.

Ultimately, debt should be viewed as a tool, not a companion for life. When interest rates on loans exceed what your money can safely earn elsewhere, holding on to long-term debt becomes an avoidable drag on wealth. Retiring high-cost loans early is not just prudent, it is one of the simplest and most effective ways to improve long-term financial health.
