Prepayment vs Investing: What Should You Do With Extra Money?
Should you close your loan early or invest the surplus? This decision is less about formulas — and more about clarity.
There is no universal answer. The right choice depends on loan interest, expected returns, risk tolerance and your comfort with debt.
The Question Almost Every Borrower Faces
If you have a home loan or any long-term loan, surplus money creates a dilemma:
- Should I reduce my loan faster?
- Or should I invest and let compounding work?
What Loan Prepayment Actually Does
Prepayment means paying extra toward principal, which reduces future interest.
| Benefit | Impact |
|---|---|
| Lower interest | Saves money over the loan life |
| Shorter tenure | Debt-free earlier |
| Certainty | Guaranteed, risk-free return |
What Investing Your Surplus Does
Investing means putting money into assets that can potentially earn more than loan interest.
| Aspect | Reality |
|---|---|
| Return potential | Higher than loan rate (long term) |
| Risk | Market volatility |
| Liquidity | Accessible if needed |
Prepay or Invest: A Clear Decision Framework
| Your situation | Better choice |
|---|---|
| High-interest loan (PL, CC) | Prepay |
| Early years of home loan | Lean toward prepay |
| Low-interest home loan | Consider investing |
| No emergency fund | Build liquidity first |
| Debt causes stress | Prepay for peace |
The Hybrid Strategy (Best for Most People)
You don’t have to choose one extreme.
- Make small, regular prepayments
- Continue SIP investments in parallel
- Increase investments as income rises
