How long does it take to build credit?

FICO generates your first score after one account has been open for at least 6 months and reported within the last 6 months. Most people starting from zero see a first score of 650–680 around month 6–7. Reaching 720+ typically takes 12–24 months of consistent on-time payments and low utilization.

The timeline depends on two things: when you open your first reporting account and how you manage it. myFICO requires a minimum of one account open for 6 months and reported to the bureaus within the last 6 months before any score can be generated — this is the hard floor. There's no shortcut around it.

Month-by-month credit-building timeline

Month 0 — Open a secured credit card or credit-builder loan. The account is created but no score exists yet.
Month 1–5 — The account is being reported but doesn't yet meet FICO's 6-month minimum. No score is generated. Make small purchases and pay the full statement balance every month.
Month 6–7 — First FICO score typically appears. Most thin-file borrowers with no negatives land at 650–680.
Month 12–18 — Consistent on-time payments and utilization below 30% typically push scores to 680–720. Enough to qualify for most unsecured credit cards and auto loans.
Month 24+ — With a second account added (diversifying credit mix) and continued clean history, scores often reach 720–760+. At this range, most lenders offer near-prime rates.

What accelerates the timeline

Becoming an authorized user on a parent's or family member's long-standing, clean account — that account's history can appear on your report immediately, potentially generating a first score in weeks rather than months.
Opening a credit-builder loan alongside a secured card — adds installment payment history and improves credit mix from the start.
Keeping utilization under 10% — not just under 30%. The top score tier is associated with single-digit utilization.
Experian Boost or rent-reporting services — adds utility/phone/rent payment history to your Experian file, sometimes boosting VantageScore immediately (FICO impact is more limited).

What resets or slows the clock

A single late payment can erase months of progress

Payment history is 35% of your FICO score. One 30-day late payment can drop a newly established 670 score by 60–80 points — and stays on your report for 7 years. Set autopay for at least the minimum on every account. The clock on building credit is patient; the damage from a miss is not.

Key takeaways

First FICO score: 6 months after your first reporting account opens.
First usable score (650–680): month 6–7 with no missed payments.
Good credit (680–720): month 12–18 with consistent clean history.
Excellent credit (720+): month 24+ with at least two accounts and credit mix.
Autopay is non-negotiable — one missed payment can set back months of progress.
