Your credit score is one of the most influential factors in determining your loan terms. This three-digit number can mean the difference between affordable monthly payments and costly debt, or between approval and rejection. Understanding this relationship helps you make informed borrowing decisions and potentially save thousands of dollars.
Key Takeaways
- Credit scores directly impact interest rates - higher scores mean lower rates
- A 100-point difference can change your rate by 5% or more
- Loan amounts and terms also vary based on credit score
- Different lenders have different credit score requirements
- Improving your score before applying can save significant money
Understanding Credit Score Ranges
Credit scores typically range from 300 to 850, with higher scores indicating better creditworthiness. Lenders categorize these scores into tiers, each with different loan terms and rates.
| Credit Score Range | Rating | Typical APR Range | Approval Likelihood |
|---|---|---|---|
| 800-850 | Exceptional | 5.5% - 8% | Very High |
| 740-799 | Very Good | 6% - 10% | High |
| 670-739 | Good | 8% - 15% | Good |
| 580-669 | Fair | 15% - 25% | Moderate |
| 300-579 | Poor | 25% - 36% | Low |
The Direct Impact on Interest Rates
The most immediate effect of your credit score is on the interest rate you'll receive. This relationship is nearly universal across all types of loans, from personal loans to mortgages.
Example: $20,000 Personal Loan (5-Year Term)
| Credit Score | APR | Monthly Payment | Total Interest Paid |
|---|---|---|---|
| 750+ | 7% | $396 | $3,761 |
| 700-749 | 10% | $425 | $5,496 |
| 650-699 | 15% | $476 | $8,548 |
| 600-649 | 22% | $555 | $13,290 |
| Below 600 | 30% | $647 | $18,839 |
As shown above, the difference between excellent and poor credit can mean paying over $15,000 more in interest on the same loan amount!

What If You Have Bad Credit?
Having a low credit score doesn't mean you can't get a loan, but it does limit your options:
Alternative Options:
- Secured loans: Use collateral to reduce lender risk
- Co-signed loans: Add someone with better credit
- Credit unions: Often more flexible than banks
- Online lenders: Some specialize in bad credit
- Peer-to-peer lending: Individual investors may be more flexible
