Should you prepay a personal loan or invest?
Because unsecured personal loans commonly have higher rates, prepayment can offer a strong predictable benefit. The answer can change when foreclosure charges are high or very little tenure remains.
What the comparison includes
- Interest and tenure saved by a lump-sum prepayment
- Compounding if the lump sum is invested instead
- Investment of EMIs freed after the loan closes early
- Prepayment charges, inflation and an optional loan tax benefit
What numbers cannot decide
- Investment returns are uncertain; loan savings are more predictable
- Prepayment reduces liquidity and access to emergency money
- Being debt-free may matter more than the highest expected return
- Rates, taxes and lender rules can change during the remaining tenure
A practical decision rule
Enter the exact prepayment charge and keep the loan tax-benefit input at zero unless professional advice confirms otherwise. Test a conservative investment return because the loan saving does not depend on market performance.
Keep an emergency fund before using surplus cash for either option. If the result is close, splitting the amount between prepayment and investment can reduce regret and concentration risk.

How to use this result
Confirm the lender's foreclosure or part-payment charge and minimum holding period. Personal loans normally do not provide the same interest tax benefit as qualifying home loans.
