How to switch your home loan to a lower rate

A balance transfer can save lakhs in interest — if the maths works. Here is when to switch home loan lenders, and the costs to weigh first.

Why a small rate cut is a big deal On a long home loan, even a 0.5% lower rate can save lakhs over the tenure, because interest compounds on a large balance for many years. A balance transfer moves your outstanding loan to another lender offering a better rate. Done right, it's one of the highest-value money moves a borrower can make.

When switching makes sense - You still have many years left on the loan (the earlier you switch, the bigger the saving). - The new rate is meaningfully lower — enough to beat the switching costs. - Your credit score has improved since you first borrowed, unlocking better offers.

Only switch if lifetime interest saved comfortably exceeds these one-off costs.

Ask your current lender first Before moving, ask your existing bank to match the lower rate — many will, for a small conversion fee, to keep you. That can capture most of the saving with none of the paperwork.

Consider keeping the EMI, cutting the tenure When you switch to a lower rate, you can either reduce the EMI or keep the EMI the same and shorten the tenure. The second option maximises interest saved and clears the debt faster.

Do the maths before you move Compare your current loan against the new offer — including all fees — to see the real net saving. If the number is large and you have years left, switch; if it's marginal, renegotiating with your current lender is often the smarter play.
