Pay off high-interest debt first, and invest alongside low-interest debt. If a loan costs more than the realistic post-tax return you can expect from investing, repaying it is the better use of spare money. In practice, as of October 2026, that means clearing credit card dues (about 30-45% a year) and expensive personal loans before stepping up investments, while home loans at around 7.5-9.5% can usually run alongside SIPs. Keep a small emergency fund in place before doing either.
The core rule: compare rates after tax
Every rupee used to repay a loan "earns" the loan's interest rate, risk-free, because that is the interest you no longer pay. So the question is:
Is my loan's effective interest rate higher than my expected post-tax investment return?
- If yes, repay the loan.
- If no, invest, but only if you are comfortable with the investment's risk.
- If close, split the money between the two.
Two adjustments make the comparison fair:
- Tax on the loan side. Some loan interest is tax-deductible under the old regime, which lowers its effective cost.
- Tax and risk on the investment side. Equity returns are not guaranteed, and gains are taxed (equity LTCG at 12.5% above ₹1.25 lakh a year for holdings over 12 months; FD interest at your slab rate).
Typical loan rates and what to do
Indicative ranges as of October 2026. Your rate depends on your lender and credit profile.
| Debt type | Typical annual cost | Usual priority |
|---|---|---|
| Credit card revolving balance | About 30-45% | Repay first, urgently |
| Instant app / small-ticket loans | Often 20-36%+ plus fees | Repay first |
| Personal loan | About 10% to 24% | Repay early if rate is in mid-teens or above |
| Car loan | Roughly 8.5-12% | Usually invest alongside; prepay if rate is high |
| Education loan | Varies; interest deductible in old regime | Usually invest alongside |
| Home loan | Roughly 7.5-9.5% | Invest alongside; prepay partly if you prefer certainty |
The RBI raised the repo rate by 25 basis points to 5.50% on 7 October 2026, so rates on repo-linked floating loans may rise over the coming months. See how the repo rate affects your EMI.
A step-by-step order of priorities
- Pay every EMI and the full card bill on time. Missed payments damage your CIBIL score and add penalties.
- Build a starter emergency fund of at least 1 month of essential expenses. Without it, any shock goes straight back onto a credit card. See how much emergency fund you need.
- Get adequate health and term insurance, so an illness does not create new debt.
- Clear high-interest debt: credit card balances, app loans, expensive personal loans. Target the highest rate first (avalanche) or the smallest balance first (snowball) if quick wins keep you motivated.
- Complete the emergency fund to 6 months of essentials.
- Invest for long-term goals through SIPs, PPF, NPS, while paying low-cost debt such as a home loan on schedule.
- Use extra surplus to prepay the home loan if you value guaranteed savings and lower stress.
If you have several costly loans, our guide on debt consolidation explains how to combine them at a lower rate.
Worked example 1: credit card debt vs SIP
Arjun has ₹1 lakh revolving on his credit card at 3.5% a month and ₹1 lakh in spare savings.
Option A: invest ₹1 lakh, keep the card balance. If the card balance compounds at 3.5% a month for 12 months, it grows to about ₹1,00,000 × 1.035¹² = ₹1,51,107, roughly ₹51,000 of interest (before GST on interest and other charges). Even if the investment earned an illustrative 12% in a year, that is only about ₹12,000.
Option B: clear the card. He avoids roughly ₹51,000 in interest, a guaranteed saving.
The card wins by a wide margin. See how credit card interest works for why balances snowball so fast.
Worked example 2: personal loan
Meera has a ₹2 lakh personal loan at 14% for 3 years. Her EMI is about ₹6,836, and total interest over the full tenure is about ₹46,079. If she gets a ₹50,000 bonus in month 6 and prepays it, she cuts the outstanding principal and saves future interest at 14%, which is hard to beat with a low-risk investment. Before prepaying, she should check the lender's prepayment charges; many personal loans are fixed-rate and may carry a fee. Use the EMI calculator to see her EMI and interest.
Worked example 3: home loan prepayment vs SIP
Rahul has a ₹40 lakh home loan at 8.5% and ₹5 lakh to deploy. He is in the 30% slab under the old regime, and his yearly home loan interest is already above ₹2 lakh, so the ₹2 lakh deduction is fully used either way.
| Prepay ₹5 lakh | Invest ₹5 lakh in equity fund | |
|---|---|---|
| Return | 8.5% saved, guaranteed | Illustrative 11% a year, not guaranteed |
| Tax effect | None at the margin (deduction cap already used) | LTCG at 12.5% above ₹1.25 lakh a year after 12 months |
| Risk | None | Can fall 20-30% or more in bad years |
| Liquidity | Money locked in the house | Can redeem, but maybe at a loss |
Because Rahul's interest already exceeds the ₹2 lakh cap, the extra interest saved by prepaying is not tax-deductible anyway, so his effective cost is the full 8.5%. An equity fund might beat that over 10-15 years, but with real risk of underperforming. A reasonable middle path is to continue SIPs and prepay part of the loan each year. If he were on the new regime, there is no deduction for self-occupied home loan interest, which makes prepaying slightly more attractive.

When to invest even with debt
- Your employer deducts PF automatically. Employee PF (12% of basic) continues regardless, and it is a sound retirement base.
- Your loan rate is low relative to the long-term returns you can reasonably expect, and you have a long horizon.
- You have a time-bound goal, such as a child's education, where delaying investment would hurt more than paying low loan interest.
- Liquidity matters. Money used for prepayment cannot be taken back easily; investments can be redeemed if needed.
When to prioritise repayment
- Any revolving credit card balance or app loan.
- Personal loans at mid-teen rates or higher.
- Loans whose EMIs take more than about 40% of take-home pay, leaving no room for savings.
- You are close to retirement and want to enter it debt-free.
- Debt is causing stress or sleepless nights; peace of mind has real value.
Mistakes to avoid
- Redeeming investments in a market fall just to prepay a low-rate loan.
- Paying only the minimum amount due on cards while running SIPs. See the minimum amount due trap.
- Using the whole emergency fund to prepay, leaving no buffer.
- Ignoring prepayment charges on fixed-rate or business loans. RBI rules bar such charges on floating-rate loans to individuals for non-business purposes.
- Taking a new loan to invest. Borrowing to buy market-linked assets magnifies losses.
Key takeaways
- Compare each loan's effective cost with a realistic post-tax return; repay when the loan costs more.
- Clear credit card and app loan debt first; it costs about 30-45% a year or more.
- Home loans at around 7.5-9.5% can usually run alongside SIPs; splitting surplus is reasonable.
- Keep a starter emergency fund and insurance in place before aggressive prepayment.
- All returns shown are illustrative; markets are volatile and nothing here is personalised advice.
Frequently asked questions
Should I invest while I have credit card debt?
Generally no. Credit card interest in India commonly runs at about 2.5% to 3.75% a month, or roughly 30% to 45% a year, which no safe investment can reliably beat. Clear revolving card dues first, while keeping a small emergency cushion.
Is it better to prepay a home loan or invest in SIPs?
It depends on your loan rate, tax benefit and risk appetite. Prepaying gives a guaranteed saving equal to the loan rate, while equity SIPs may earn more over 10 years or longer but without any guarantee. Many people split surplus money between the two.
Should I stop my SIPs to repay a personal loan?
If the personal loan rate is in the mid-teens or higher and the lender allows prepayment at low cost, redirecting new surplus to it often makes sense. Pausing SIPs briefly is reasonable, but avoid redeeming long-term investments in a market fall just to prepay.
Do I lose a tax benefit if I prepay my home loan?
Possibly, under the old tax regime. Interest on a self-occupied home loan is deductible up to ₹2 lakh a year (old Section 24(b), now Section 22 of the Income-tax Act, 2025), so prepaying reduces that deduction. Under the new regime, there is no such deduction for a self-occupied house.
Are there prepayment charges on floating-rate loans?
RBI rules bar banks and NBFCs from charging foreclosure or prepayment penalties on floating-rate term loans to individuals for non-business purposes. Fixed-rate loans and business loans may carry charges, so check your loan agreement.
