How long does it take to rebuild a credit score from 600 to 750? As few as 2–4 months if high utilisation is your only problem — and as long as 24 months if you're carrying a written-off loan. The difference isn't effort. It's knowing which problem you actually have. And while you figure that out, a 600 CIBIL score is already costing you ₹5–8 lakh in extra interest on a single ₹25 lakh home loan over 20 years.
A 600 score sits in the "Poor" band (600–649) on the 300–900 scale. Before repair timelines matter, the rupee cost of inaction should.
A 600–649 borrower pays 16–22% interest on personal loans. A 750+ borrower pays 10–14%. For sub-600 scores, that band widens further to 24–36%. That gap — between your current score and 750 — is worth ₹5–8 lakh in additional interest on a ₹25 lakh home loan over 20 years (CreditHelp India).
In my research, the number that surprised me most was how consistently people optimise for down payment size while ignoring how much their score costs them on the rate side — often multiples of what any extra savings would offset.
| Factor | Score 600–649 | Score 750+ |
|---|---|---|
| Personal loan rate | 16–22% | 10–14% |
| Home loan eligibility | Likely rejected by major banks | Approved; best-rate eligible |
| Extra interest (₹25L / 20 yrs) | +₹5–8 lakh vs. 750+ borrower | Baseline |
| Premium credit card access | Denied | Full access |
Most major banks require a 700–750 minimum CIBIL score to even consider a personal or home loan application (CreditHelp India). If you're at 680, you're not in a comfortable buffer — you're at the floor.
The honest answer: your timeline to 750 depends entirely on why your score is 600. Same destination, very different routes. Understanding how a credit score is calculated in India is the foundation before anything else.
One missed payment can drop your score by 50–100 points (CreditHelp India). A written-off loan can push you below 540. These aren't the same problem, and treating them identically is why most credit repair advice fails.
| Scenario | Cause | Starting Score | Realistic Timeline to 750 |
|---|---|---|---|
| A | 2 missed EMIs, now paying regularly | 610 | 4–6 months |
| B | One settled credit card | 580 | 12–18 months |
| C | Written-off personal loan | 520 | 18–24+ months |
| D | High utilisation only, no default | 620 | 2–4 months after reduction |
For Scenario A borrowers, IndianBanker.com's data supports what I'd call the six-month sprint — six months of zero missed payments, utilisation below 30%, and no new applications. That's roughly two payroll cycles of discipline for a ₹5–8 lakh outcome. The math is absurd in your favour.
For Scenario C, I won't promise 6 months. But here's what most guides won't say clearly: defaults don't weigh on your score at full strength for all 7 years. Their impact diminishes progressively as positive history accumulates in more recent reporting cycles. Eighteen to twenty-four months of disciplined action genuinely can rebuild to 750.
Before the roadmap, here are the mistakes that silently add 6–12 months to your recovery if you make them in Month 1.
Closing old credit cards. This feels disciplined. It does the opposite of what you intend. Closing a card reduces your total available limit, which immediately raises your utilisation ratio — worth ~30% of your score. It also shortens your credit history length (~15%). A card held for five years and rarely used is one of your most valuable credit assets. Keep it open; run one small transaction every quarter to prevent dormancy.
Applying to multiple lenders simultaneously. Every application triggers a hard inquiry — 5–10 points dropped per application (IndianBanker.com). Five applications in one month can erase 25–50 points while you're trying to rebuild. With RBI's weekly reporting effective July 2026, all five inquiries appear on your report within days — signalling acute financial distress to every lender reviewing your file simultaneously. Always use soft-inquiry eligibility checkers first. Wait a minimum of 3–6 months between applications (IndianBanker.com, CreditKlick).
Assuming a "Settled" account is a "Closed" account. This one costs borrowers years. More on this below.
This is a sequence, not a tip list. Each phase attacks the highest-leverage factors first.
Month 1 — Diagnose Before You Prescribe
Pull free reports from all four bureaus: CIBIL, Experian, Equifax, and CRIF High Mark. Under CICRA 2005, you're entitled to one free annual report from each. A single major reporting error can drag your score by 30–120 points (CreditKlick, IndianBanker.com). Dispute it through CIBIL's portal — this triggers a mandatory 30-day resolution window under the NBFC Credit Information Reporting Directions 2025. In practice, some bureaus resolve in 45–60 days, which is exactly why the ₹100 per calendar day compensation clause for unresolved disputes matters and almost no one exercises it.
Months 2–3 — Attack Utilisation First
Credit utilisation carries ~30% of your score weight — and it's the fastest lever to move. Practical illustration: if you have a ₹4 lakh total credit limit, you should be using less than ₹1.2 lakh (30%). If you're using ₹85,000 on a ₹1 lakh card, that's 85% utilisation — severe score damage. Pay it down to 30%. Expected improvement: 30–80 points within 1–2 reporting cycles (CreditKlick).
One tactic competitors miss: banks report your statement balance, not your due-date payment. Pay before the statement generation date. If you've spent ₹60,000 on a ₹1 lakh card and pay ₹40,000 before the statement generates, the bureau sees ₹20,000 utilisation (20%) — not ₹60,000 (60%).
Since January 2025, lenders have moved to fortnightly reporting — a transition phase before weekly reporting kicks in on July 1, 2026. From July 2026, lenders submit data on the 9th, 16th, 23rd, and last day of each month. Good behaviour now reflects in your score within 7–10 days, not the old 30–45 day wait.
Months 3–6 — Build Positive History
Apply for exactly one FD-backed secured credit card. Minimum FD requirement: ₹10,000–₹25,000; your credit limit will be approximately 80–85% of that FD amount. Use 20–30% of the limit monthly and pay in full before each statement date.
The FD-backed card also improves your credit mix — worth roughly 10% of your score — by adding a revolving credit line to what may currently be only instalment EMIs. You don't need to optimise for this factor specifically; the secured card takes care of it automatically. For a deeper look at maximising your score long-term, see how to increase your credit score to 800 in 2026.
Payment history carries 35–40% of your total score weight — the single largest factor. Every on-time EMI is compounding. Six months of clean history creates a visible trajectory toward 750 (Moneycontrol).
This is the most consequential credit distinction that almost no personal finance content explains clearly — and it affected millions of Indian borrowers between 2020 and 2022.
A colleague of mine — salaried, disciplined, 28 years old — thought his COVID settlement was behind him. Three years later, a home loan underwriter flagged the "Settled" tag and his rate came in 2% higher than he'd budgeted for. Here's what almost no personal finance content explains clearly.
"Settled" means you paid less than the full outstanding amount. The bureau tags it as a partial default — and that tag stays on your report for 7 years from the date of the adverse event.
"Closed" means full repayment. Clean signal.
A "Settled" account at 550–580 puts you on a 12–18 month path to 750 (Olyv). A fully closed account in the same range recovers in 6–12 months. That six-month gap is the direct cost of the tag.
The conversion path most people don't know exists: some lenders will allow you to pay the remaining waived balance and update the status from "Settled" to "Closed." It requires direct negotiation with the lender — it is not automatic. But it is the only mechanism that removes the flag rather than waiting for it to age out. Given that the interest rate difference between a visible "Settled" flag and a 750+ clean file is 2–4% (CreditHelp India), this negotiation is often worth more than any other single action in this roadmap. Explore the full benefits of an 800 credit score to understand the long-term upside of clearing this flag.
Quick Recap
✅ A 600 CIBIL score costs you ₹5–8 lakh in extra interest on a ₹25 lakh home loan over 20 years — the damage is running while you read this.
✅ Your timeline to 750 ranges from 2–4 months (high utilisation only) to 24+ months (written-off loan) — cause determines everything.
✅ Every hard inquiry costs 5–10 points per application — five simultaneous applications can erase 25–50 points of progress overnight.
Action Steps
The gap between 600 and 750 is not a mystery. It is a sequence of specific, executable steps with a known timeline. You now have both.
