Quick Summary: If your loan interest rate is higher than your expected investment returns, prepay the loan. If your investment returns are higher than your loan rate, invest instead. For most home loans at 7-9%, investing in diversified assets often gives better long-term results.
The Core Question
You have $10,000 in extra savings. Your home loan interest rate is 8.5%. Should you prepay $10,000 on your loan or invest that money instead?
The answer depends on one simple comparison: your loan interest rate vs your expected investment return rate.
Scenario 1: Prepay the Loan
If you prepay $10,000 on a $200,000 loan at 8.5% with 15 years remaining:
- You save approximately $18,500 in future interest payments
- Your loan tenure reduces by approximately 14 months
- This is a guaranteed return of 8.5% on your $10,000
Scenario 2: Invest the Money
If you invest $10,000 in a diversified portfolio for 15 years at various return rates:
- At 7% annual return: $10,000 grows to $27,590 (profit $17,590)
- At 10% annual return: $10,000 grows to $41,770 (profit $31,770)
- At 12% annual return: $10,000 grows to $54,740 (profit $44,740)
When to Prepay Your Loan
- Your loan interest rate is high (above 10-12%)
- You are in the early years of the loan (more interest to save)
- You have no high-interest debt (credit cards, personal loans)
- You have an emergency fund already in place
- You value the peace of mind of being debt-free
When to Invest Instead
- Your loan rate is low (below 8%) and you expect market returns above 10-12%
- You have employer-matched retirement contributions you are not maximizing
- You have tax advantages from keeping the loan (mortgage interest deduction)
- You are young and have a long investment horizon ahead
Important: Always maintain an emergency fund of 3-6 months of expenses before either prepaying your loan or investing. Financial security comes first.
