Debt isn't automatically bad — but some of it is genuinely toxic, and the difference is mostly the interest rate. Before investing aggressively, it's worth ranking what you owe and clearing the expensive end.
The hierarchy of debt
Toxic (clear first, urgently):
- Credit-card revolving balances — roughly 36–42% a year. No investment reliably beats this. Paying only the "minimum due" is a trap that keeps the balance compounding against you. Pay in full, every month.
- Personal loans / BNPL / consumer EMIs — often 12–24%. Convenient and costly.
Tolerable (manage, don't fear):
- Home loan — typically ~8–9%, secured against an asset, with a tax deduction on interest (up to ₹2 lakh a year under Section 24(b), old regime) that lowers the effective rate further.
- Education loan — interest qualifies for deduction under Section 80E (no cap, for 8 years).
The rule is simple: attack the highest interest rate first, regardless of balance size. A ₹40,000 card balance at 40% costs more than a ₹4 lakh home loan at 9%.
The prepay-vs-invest question
Once the toxic debt is gone, the common dilemma is: extra money — prepay the home loan, or invest it?
Think of prepaying as a guaranteed, risk-free return equal to the loan's after-tax interest rate. Prepaying a 9% loan effectively "earns" you 9%, certain. Investing might earn more (equity, long-term) — but it's uncertain and taxable.
So the comparison is: after-tax loan rate vs. realistic after-tax expected return, adjusted for risk.
- If your effective home-loan rate is ~7–8% after the Section 24(b) benefit, long-term equity may beat it — but with volatility and no guarantee.
- A guaranteed 8–9% (prepaying) is genuinely attractive, especially for the risk-averse or those near retirement.
There's no universal answer, but some guardrails:
- Never prepay at the cost of your emergency fund, insurance, or employer-matched retirement contributions (EPF/NPS).
- High-rate loans (anything in double digits) — prepay before investing.
- Low-rate home loans held by disciplined long-term equity investors can reasonably run their course while they invest the surplus.
- Don't ignore the behavioural value: many people sleep better debt-free, and that's a legitimate reason to prepay even when the spreadsheet is a coin-flip.
The order of operations
A sensible sequence: (1) clear toxic debt, (2) emergency fund + insurance, (3) capture any employer retirement match, then (4) split surplus between prepaying tolerable debt and investing — weighted by the rate gap and your temperament.
Debt isn't the enemy. Expensive debt is.
