How Your Credit Works — and How Debt Affects It
Your credit score is mostly about two things: paying on time and how much you owe. Here's what's really in the score, how debt moves it, and the myths to ignore.
Credit scores run from 300 to 850, and in the FICO model two factors drive most of the result: payment history (about 35%) and amounts owed, mainly your credit utilization (about 30%). That's roughly two-thirds of your score. Debt affects it most when balances push your utilization up or when payments are missed — so paying on time and keeping balances low are the biggest levers.
What is a credit score?
A credit score is a number lenders use to estimate how likely you are to repay. The most common models, FICO and VantageScore, both run on a 300–850 scale, with higher numbers signaling lower risk (myFICO; VantageScore). It's built from the information in your credit reports — not your income or savings.
What makes up your FICO score?
| Factor | Weight | What it means | |
|---|---|---|---|
| Payment history | 35% | Whether you pay on time | |
| Amounts owed (utilization) | 30% | How much of your available credit you're using | |
| Length of credit history | 15% | How long you've had credit | |
| New credit | 10% | Recent applications and new accounts | |
| Credit mix | 10% | The variety of credit types you manage |
How does debt affect your score?
Debt moves your score mostly through two of those factors. High balances raise your credit utilization — the CFPB suggests keeping it under 30% of your limits — which can pull the 30% "amounts owed" component down. And a missed payment hits payment history, the single biggest factor. The flip side is encouraging: paying on time every month and reducing balances are the two most reliable ways to help your score over time.
What credit myths should you ignore?
- Myth: checking your own credit hurts it. Reality: pulling your own report is a soft inquiry and does not affect your score (CFPB).
- Myth: you must carry a balance to build credit. Reality: paying your statement in full still builds positive payment history — you don't need to pay interest to score well.
- Myth: closing an old card always helps. Reality: closing a card can raise your utilization and shorten your history, which may lower your score.
How does a debt management plan fit in?
Because a debt management plan keeps your accounts current and helps you pay balances down, it tends to support the two factors that matter most — payment history and utilization — over time. It is not the same as debt settlement, which usually requires falling behind. We don't promise a specific score change; your counselor will explain what to expect for your situation.
Credit scoring is general here and simplified; the exact weighting can vary by person and model. For your own reports and scores, check with the credit bureaus and your lenders.
