An additional annual instalment paid towards principal can reduce the interest charged on a home loan and shorten its term, but the savings depend on timing, lender rules and the borrower’s wider finances.
For Indian homebuyers, a long mortgage can feel manageable at first and then increasingly heavy as interest accumulates over time. Business Today’s example of a ₹50 lakh home loan at 8.5% over 20 years shows why: the monthly instalment comes to about ₹43,391, and the borrower would end up paying far more in interest than in principal if nothing changes along the way. The basic point is simple: any extra amount that goes directly towards the loan balance can reduce the interest charged in later years.
That is why the idea of paying one additional EMI a year has attracted attention. In the Business Today calculation, the extra payment is used to chip away at the outstanding principal, which in turn lowers the interest burden over the remaining loan term. Comparable examples from Finnable and BankCreds say that this approach can trim several years from a 20-year home loan, although the exact benefit depends on when the extra payment is made and how the lender applies it.
The timing matters because home loans are front-loaded with interest. Early in the repayment schedule, a larger share of each EMI goes towards interest rather than principal, so an extra payment made sooner generally has a stronger effect than one made later. That is why some lenders and financial education platforms recommend using annual bonuses, tax refunds or other windfalls for part-prepayment, rather than waiting until the end of the year.
There is, however, an important practical detail: borrowers should confirm whether the lender will apply the extra amount straight to principal and whether any conditions apply. The Reserve Bank of India banned prepayment charges on floating-rate home loans in 2012, according to Finnable, but fixed-rate loans and individual lender policies can differ. Borrowers should also weigh the trade-off against emergency savings and other household commitments before committing to aggressive prepayment.
Financial planners generally treat this as a disciplined but not universal strategy. If cash flow allows, one extra instalment a year can shorten the loan and cut total interest, but the actual saving will vary from one borrower to another. Amortisation calculators from lenders and repayment tools can help check the likely effect before money is moved, and that is especially useful for anyone deciding whether to reduce the loan term or simply lower the monthly EMI.
