Your credit score looks like a single mysterious number, but it is really a summary of your borrowing behavior. Scoring models weigh five factors. They do not weigh them equally, and knowing which ones matter most tells you exactly where to focus. Here is each factor in plain English, ordered roughly by importance.
1. Payment history: the heavyweight
This is the biggest factor by a wide margin. It asks one question: do you pay your bills on time. Every on time payment builds your record. Late payments, collections, and bankruptcies damage it, with more recent and more severe problems hurting the most.
2. Amounts owed and utilization: the second big one
The next biggest factor looks at how much of your available credit you are using. This is called credit utilization. If you have a card with a ten thousand dollar limit and you carry a two thousand dollar balance, your utilization on that card is twenty percent. Lower is generally better.
3. Length of credit history: the quiet contributor
This factor looks at how long your accounts have been open, including the age of your oldest account and the average age of all accounts. Longer history generally helps, because it gives the scoring model more evidence of how you handle credit.
4. New credit: the small ding
Opening several new accounts in a short period can lower your score a bit. Each application typically triggers a hard inquiry, which is a lender checking your credit because you asked for credit. One inquiry is minor. A burst of them suggests you are hungry for credit, which reads as risk.
5. Credit mix: the finishing touch
The smallest factor looks at the variety of credit types you have: credit cards, installment loans like auto or student loans, a mortgage. A healthy mix can help slightly, because it shows you can handle different kinds of borrowing.
Do not open accounts just to improve your mix. Taking out a loan you do not need costs real money to chase a small scoring benefit. If your life naturally includes different credit types over time, the mix takes care of itself.
What does not affect your score
A few things people worry about needlessly. Checking your own credit is a soft inquiry and never hurts your score. Your income, savings, and job title are not factors. Debit card use does not build credit. And being an authorized user can help or hurt depending on how the primary user manages the account, so choose that arrangement carefully.
How to use this knowledge
If your score needs work, the priority list writes itself. First, get every payment on time and keep it that way. Second, pay down revolving balances to lower utilization. Third, leave old accounts open and avoid opening new ones right before you need credit. Fourth, let time do its work. There is no legitimate shortcut. Anyone selling rapid score repair is selling something else.
The bottom line
Payment history matters most, utilization is next, then length of history, new credit, and mix round it out. That order is your action plan. Pay on time, keep balances low, be patient, and the number takes care of itself.

Questions people ask me about this
What should I know about the heavyweight?
This is the biggest factor by a wide margin. It asks one question: do you pay your bills on time. Every on time payment builds your record. Late payments, collections, and bankruptcies damage it, with more recent and more severe problems hurting the most. A single 30 day late payment can sting, and a 90 day late payment stings much worse.
What should I know about the second big one?
The next biggest factor looks at how much of your available credit you are using. This is called credit utilization. If you have a card with a ten thousand dollar limit and you carry a two thousand dollar balance, your utilization on that card is twenty percent. Lower is generally better. High utilization signals risk to lenders.
What should I know about the quiet contributor?
This factor looks at how long your accounts have been open, including the age of your oldest account and the average age of all accounts. Longer history generally helps, because it gives the scoring model more evidence of how you handle credit. The practical takeaway: think twice before closing your oldest card.
What should I know about the small ding?
Opening several new accounts in a short period can lower your score a bit. Each application typically triggers a hard inquiry, which is a lender checking your credit because you asked for credit. One inquiry is minor. A burst of them suggests you are hungry for credit, which reads as risk. Rate shopping gets special treatment.
