Building & Repairing Credit
From a thin file to 800-plus, the moves that actually move the FICO needle: secured cards, credit-builder loans, authorised-user strategy, utilisation tactics and the 12-month plan that takes a sub-600 score into the 700s.
What is Building Credit?
Credit building is the deliberate work of generating positive payment history, credit age and utilisation data on the three major bureaus (Equifax, Experian, TransUnion). FICO and VantageScore weight five factors, payment history, amounts owed, length of history, new credit and credit mix, so the playbook is the same regardless of starting score: always pay on time, keep utilisation under 30% (ideally under 10%), age accounts, limit hard pulls and diversify only when natural.
Key Takeaways
- Payment history alone drives ~35% of a FICO score, no other lever matters as much.
- Utilisation is the only factor you can change inside 30 days; paying balances before the statement closes is the fastest score lift.
- Authorised-user history can add years of credit age overnight, used responsibly it's a legitimate accelerator, not a hack.
- Hard inquiries hurt for ~12 months and disappear from scoring after two years; soft pulls never affect the score.

Frequently Asked Questions
- How fast can I build credit from zero?
- A secured card with on-time payments typically produces a usable score in 6 months and a 700+ score in 18–24 months. The single fastest accelerator is becoming an authorised user on a seasoned account.
- Does carrying a small balance help my score?
- No, this is the most common credit myth. Pay statements in full; the bureau records the statement-date balance regardless of whether you let it ride into interest.
- Should I close old credit cards?
- Usually not. Closing an unused fee-free card shortens your average account age and raises utilisation, both score-negative.
