Home loan prepayment vs investing: Where should extra cash go?
When you borrow money from a bank to buy a house, you have to pay it back little by little every month, plus some extra money called interest.
Interest is like a fee the bank charges for letting you use its money.
If you get some extra cash, like a bonus at work, you have two choices.
You can give some of that money to the bank early, which is called prepayment, and that lowers how much interest you will pay later.
Or you can put the money into investments, like stocks or mutual funds, hoping they grow and earn more money.
The best choice depends on how much your loan costs compared to what your investments might earn.
Paying early is often smart because interest is calculated on the money you still owe, so a smaller loan means less interest.
But you should always keep some emergency savings so you are not left without money for urgent needs.
A financial expert advises that people should think carefully about their situation and talk to a certified financial advisor before deciding.
There is no one-size-fits-all answer for everyone.
Home loan borrowers face a choice between prepaying their loan and investing surplus cash in assets such as equities or mutual funds.
Interest is calculated on the outstanding principal, so prepaying early in the loan tenure significantly lowers total interest payable.
Atul Monga, CEO & Co-Founder of BASIC Home Loan, says prepayment is better when surplus funds earn less than the borrowing cost, especially early in the loan cycle.
Borrowers should balance prepayment with liquidity, maintain a well-planned emergency fund, and consider tax implications before making a large prepayment.
Under RBI rules, banks cannot charge foreclosure or prepayment penalties on floating-rate home loans, but borrowers should check terms for fixed-rate or other loan structures.

Prepayment advocates
Investment advocates
Best use of surplus cash
Prepayment advocates
Repaying debt early lowers the interest burden, especially when surplus funds earn less than the borrowing cost and the borrower is early in the loan cycle.
Investment advocates
Investing surplus in equities, mutual funds or similar growth assets can beat inflation and generate returns that outperform the loan's cost.
Liquidity and emergencies
Prepayment advocates
Becoming debt-free as soon as possible reduces financial strain and future interest outgo.
Investment advocates
Using all surplus cash for repayment can stretch the borrower and leave inadequate liquidity for unforeseen emergencies or other financial objectives.
Tax and loan terms
Prepayment advocates
Early prepayment cuts the principal on which future interest is calculated, reducing overall borrowing costs.
Investment advocates
Borrowers must consider the tax implications and compare post-tax investment returns, and check specific terms for fixed-rate loans where penalties may apply.
