Should You Prepay Your Home Loan or Invest the Money?
Prepay If
- Loan interest rate is higher than expected investment returns — prepayment gives a guaranteed return
- You have a sufficient emergency fund
- Your income is stable
Avoid Prepaying If
- You'll get better investment returns elsewhere (e.g. equity at 12%+ CAGR)
- Your monthly cash flow is tight or unstable
- There is job or income uncertainty
Best Time to Prepay Your Home Loan
In the initial years of a home loan, a large portion of your EMI goes towards paying interest rather than the principal amount. This is due to the way amortization works.
As a result, making prepayments during the early phase of your loan — typically within the first 5 to 7 years — can dramatically reduce the total interest payable. Late-stage prepayments, while still helpful, usually offer limited benefits compared to early action.
