What the score is actually measuring
Most of a credit score comes from two things: paying on time and using only a small share of the credit available to you. Everything else — account age, credit mix, new applications — matters far less at the start.
- Payment history is the largest single factor. One missed payment can sit on your file for years.
- Utilisation is your balance divided by your limit. Under roughly 30% is safe; under 10% is better.
- Length of history only grows with time, which is the entire argument for starting early.
