What Is a Credit Score?
A credit score is a numerical summary of your creditworthiness — essentially, how reliably you've managed borrowed money in the past. Lenders use it to decide whether to approve you for credit cards, loans, and mortgages, and at what interest rate. Landlords and some employers also check credit reports during their vetting process.
Scores typically range from 300 to 850, with higher being better. The exact scale and calculation method can vary by country and credit bureau, but the underlying principles are consistent.
What Goes Into a Credit Score?
While different scoring models weigh factors slightly differently, the main components are generally:
| Factor | Approximate Weight | What It Measures |
|---|---|---|
| Payment history | ~35% | Do you pay bills on time? |
| Credit utilization | ~30% | How much of your available credit are you using? |
| Length of credit history | ~15% | How long have your accounts been open? |
| Credit mix | ~10% | Do you have a variety of credit types? |
| New credit inquiries | ~10% | Have you applied for a lot of new credit recently? |
What's Considered a Good Score?
- 800–850: Exceptional — you'll qualify for the best rates available
- 740–799: Very Good — access to most credit products at favorable terms
- 670–739: Good — generally acceptable to most lenders
- 580–669: Fair — may face higher interest rates or limited options
- Below 580: Poor — most traditional lenders may decline applications
How to Improve Your Credit Score
1. Pay Every Bill on Time
Payment history is the single largest factor in your score. Even one missed payment can have a noticeable negative impact. Set up automatic payments for at least the minimum amount due so you never accidentally miss a deadline.
2. Reduce Your Credit Utilization
Credit utilization is the percentage of your available credit that you're currently using. For example, a $2,000 balance on a $10,000 credit limit equals 20% utilization. Most experts recommend keeping utilization below 30%, with under 10% being ideal for the highest scores.
3. Don't Close Old Accounts
Closing a credit card reduces your total available credit (which raises your utilization ratio) and can shorten your average credit history length. Unless a card has fees you can't justify, it's usually better to keep it open with occasional small purchases.
4. Limit Hard Inquiries
When you apply for new credit, the lender performs a "hard inquiry" on your report. Multiple hard inquiries in a short period signal financial stress to lenders. Only apply for new credit when you genuinely need it.
5. Check Your Credit Report for Errors
Errors on credit reports are more common than people realize. Incorrect accounts, wrong balances, or fraudulent entries can all drag your score down. You're entitled to free periodic credit report checks — review yours and dispute any inaccuracies with the relevant credit bureau.
How Long Does It Take to Improve a Credit Score?
There's no overnight fix. Building a strong credit score is a gradual process. Consistent on-time payments and lowering utilization can show results within a few months. Recovering from a missed payment or default can take a year or more, but the impact does diminish over time.
Key Takeaways
