Prepay Loan vs Invest: Where Should Your Extra Money Go?

Prepaying an 8.5% home loan gives a guaranteed, risk-free return equal to your effective post-tax loan interest rate (~7.5% - 8.5%). Investing in equity mutual funds offers potential 12% returns with market risk.

Key Financial Takeaways

  • Effective home loan interest rate is 8.5% (or ~7.2% if claiming Section 24b tax deductions under Old Regime).
  • Equity mutual fund expected return is 11% to 13% long term.
  • The Hybrid Strategy: Prepay 50% of surplus to reduce debt stress and invest 50% into equity SIPs.

The Psychological vs Pure Mathematical Angle

Mathematically, investing beats prepaying as long as net investment returns exceed loan interest rate by at least 3-4%.

Psychologically, being debt-free provides immense mental peace and eliminates monthly cash flow vulnerabilities.

Frequently Asked Questions

Should I prepay expensive personal loans first?

Always! High-cost loans (personal loans at 12-18% or credit card debt at 36-42%) should be paid off aggressively before making any discretionary investments.
