About this calculator

How-to: enter your current credit score, total balances, total credit limits and account age, then toggle the actions you're considering. We model directional impact using FICO's category weights (Payment History 35%, Amounts Owed 30%, Length of History 15%, Credit Mix 10%, New Credit 10%). These are estimates — actual FICO / Experian / Equifax reactions vary.

Frequently asked questions

Should I close old credit cards?

Generally no. Closing lowers your total credit limit (raising utilisation) and shortens your average account age. Only close if the annual fee outweighs the score cost.

How fast do late payments come off?

Late payments stay on your credit report for 7 years, but their impact fades — the biggest hit is in the first 12 months. A 90+ day late or collections is far more damaging than a single 30-day late.

Does checking my own score hurt it?

No. Soft inquiries (self-checks, pre-approvals) don't affect your score. Only hard inquiries (new credit applications) do, and each typically costs 5–10 points for 12 months.
