Good Debt vs Bad Debt in India: A Framework to Decide

What Makes a Debt "Good" or "Bad"?

The popular definition is simple: good debt makes you richer; bad debt makes you poorer. But in practice the line blurs. A home loan can be good debt that becomes a trap if the EMI consumes 60% of your take-home pay. The real framework has three questions:

1. Does the borrowed asset appreciate or generate income?
2. Is the interest rate below your expected investment return?
3. Is the repayment comfortably within your cash flow?

If you can answer "yes" to all three, the debt is almost certainly working for you. If even one answer is "no", you need to think carefully before borrowing.

The Classic Good Debts in India

Home loan. Property in metro and tier-1 cities has historically appreciated at 6–10% per year. Interest rates on home loans currently sit around 8.5–9.5% p.a. After accounting for the Section 24(b) deduction (up to ₹2 lakh on interest for self-occupied property) and Section 80C benefit on principal, the effective cost can drop to 6–7% for a 30% bracket taxpayer. If you buy in a city with strong demand, the math favours borrowing.

Worked example: Rohan buys a ₹60 lakh flat in Pune with ₹15 lakh down and a ₹45 lakh home loan at 9% for 20 years. His EMI is ₹40,490. Over 20 years, the property appreciates to approximately ₹1.8 crore (at 5.7% p.a. CAGR). His total interest outgo is ₹52 lakh — but his net gain after adjusting for the original down payment and interest paid is still ₹68 lakh in nominal terms, plus he had a home to live in.

Education loan. An MBA from a top IIM can cost ₹25–30 lakh in fees alone. Many students fund this with education loans at 10–12% p.a. If the degree lifts annual salary from ₹8 lakh to ₹25 lakh, the loan pays for itself in under 18 months of incremental earnings. The key condition: the return on education (income uplift) must exceed the cost of debt (interest rate). This holds for professional degrees at recognised institutions — it is far less certain for overpriced private colleges with poor placement records.

Business loan. A small business borrowing ₹10 lakh at 14% to buy machinery that generates ₹3 lakh additional profit per year is doing exactly what debt is meant to do: leveraging capital to earn a return above its cost.

The Classic Bad Debts in India

Credit card revolving balance. This is the most destructive debt available to ordinary Indians. Interest rates range from 36% to 44% per annum — compounded monthly. A ₹50,000 balance paid with minimum payments takes over 5 years to clear and costs ₹1.1 lakh in interest. No investment in India reliably returns 40% p.a. to offset this cost.

Consumer durables loans and BNPL. "Zero-cost EMI" schemes on phones, televisions, and appliances often include a processing fee and GST on interest that translate to an effective annualised rate of 14–18%. Unlike a home or education, the asset depreciates instantly — a ₹80,000 phone is worth ₹40,000 in two years.

Personal loans for lifestyle spending. Wedding loans, vacation loans, and "top-up" personal loans for discretionary spending cost 12–18% p.a. There is no asset and no income on the other side — only a liability. Indians take personal loans for weddings averaging ₹5–10 lakh. At 15% interest over 3 years, the total repayment is ₹12–24 lakh for an event that lasted a week.

Gold loans used impulsively. Gold loans are sometimes the only option for those without credit history. At 18–24% annualised, they are expensive. Used for a productive short-term purpose (bridging a business payment gap), they can be justified. Used to fund consumption, they are dangerous.

The Grey Zone: Debts That Could Go Either Way

Two-wheeler and car loans. Vehicles depreciate, so strictly speaking they are bad debt. But a motorbike or car may be required to reach your job. Treat these as a necessary cost, not an investment. Keep the tenure short (3 years maximum), put a large down payment to reduce interest, and avoid top-end models that require high loans.

Gold as collateral for investment. Some investors use gold loans to fund SIP top-ups or equity purchases during market corrections, intending to repay quickly. This is speculative and only appropriate for financially disciplined individuals.

The Debt-to-Income Ratio Test

A healthy debt-to-income (DTI) ratio in India is below 40% — meaning your total EMIs should not exceed 40% of your gross monthly income. Beyond 50%, you are in stressed territory where any income disruption becomes a crisis.

Worked example: Sunita earns ₹80,000 per month. She has a home loan EMI of ₹22,000 and a car loan EMI of ₹8,000. Her DTI is (₹30,000 / ₹80,000) = 37.5% — manageable. If she now adds a personal loan EMI of ₹8,000, her DTI rises to 47.5%. Any month she falls sick or loses a client, she is in trouble.

How to Apply the Framework Before Borrowing

Ask these questions in order:

1. What is the interest rate after tax? (Adjust for any deduction like 24(b) or 80E.)
2. What return does this debt enable — capital appreciation, income, or nothing?
3. What is my DTI before and after this loan?
4. What happens to my repayments if my income drops 30%?

If the after-tax rate is below your expected return and the DTI stays below 40% even under stress, the debt is defensible. If the debt funds consumption with no asset on the other side and pushes DTI above 45%, walk away.

The Takeaways

• Good debt funds assets that appreciate (home, education, business) at a cost below the asset's return; bad debt funds consumption at rates no investment can match.
• Credit card revolving balances at 36–44% p.a. are the most toxic debt available — always pay the full statement balance.
• Personal loans for weddings and vacations are lifestyle debt: the asset depreciates to zero the moment the event ends.
• Keep your total EMI burden below 40% of gross income to maintain financial resilience.
• Before borrowing, run the three-question test: Does the asset appreciate or earn? Is the rate below your return? Does the EMI fit your cash flow comfortably?
• Good debt used wisely — like a home loan with proper tax planning — can accelerate wealth building; bad debt even in small amounts compounds silently into a major setback.
