What Makes Up Your Credit Score: The Five Factors
Your credit score can feel mysterious, but it's built from five understandable factors. Once you know what they are and how much each one weighs, you can focus your effort where it actually moves the needle.
The five factors, roughly weighted
Most scoring models are built from the same five ingredients. The exact math is proprietary, but the general weighting is well understood:
1. Payment history — the biggest factor
Whether you pay on time is the single most important input, making up roughly a third or more of your score. A history of on-time payments builds your score steadily; late payments, collections, and defaults hurt it significantly. This is why setting up autopay for at least the minimums is one of the highest-value habits you can build.
2. Credit utilization — how much you're using
This is the share of your available revolving credit that you're currently using. If you have $10,000 in total credit card limits and carry $4,000, your utilization is 40%. Lower is better, and keeping utilization well below 30% — ideally lower — helps. This factor updates quickly, so paying down balances is one of the fastest ways to improve a score.
3. Length of credit history
The longer your accounts have been open and in good standing, the better. This is why closing your oldest credit card can sometimes backfire, and why opening many new accounts at once can pull down your average account age.
4. Credit mix
Having a healthy variety of credit types — revolving accounts like credit cards and installment loans like a car or student loan — can modestly help your score. It's a smaller factor, so it's not worth taking on debt you don't need just to diversify.
5. New credit and inquiries
Applying for a lot of new credit in a short window can ding your score, since it can signal risk. A single mortgage-shopping period is usually treated gently by scoring models, but opening several new accounts right before applying is worth avoiding.
Quick wins vs. the long game
Some moves help fast; others take time:
- Fast: paying down credit card balances to lower utilization, and correcting errors on your credit report.
- Slow but powerful: building a long, consistent history of on-time payments. There's no shortcut for time.
Myths that waste your effort
- "Checking my own score hurts it." Checking your own credit is a soft inquiry and does not lower your score.
- "I should carry a small balance to build credit." You don't need to carry debt; paying in full still builds history and avoids interest.
- "Closing old cards helps." It can actually hurt by reducing your available credit and shortening your history.
Your score isn't the only thing lenders look at, and a lower score often means a different program rather than a dead end. If past credit events are your concern, we've written specifically about the options there.
