Your credit score affects your mortgage rate, car loan rate, apartment applications, and sometimes even job applications. A difference of 50 points on your credit score can mean thousands of dollars in extra interest over the life of a loan. Understanding what a good score looks like — and how to get there — is one of the most valuable things you can do for your financial health.
The most widely used credit scoring model is FICO, which ranges from 300 to 850. Here's how the ranges break down:
| Score Range | Rating | What It Means |
|---|---|---|
| 800–850 | Exceptional | Best rates available, easiest approvals |
| 740–799 | Very Good | Better than average rates, strong approvals |
| 670–739 | Good | Near or above average, most lenders approve |
| 580–669 | Fair | Some approvals, higher interest rates |
| 300–579 | Poor | Difficult approvals, very high rates or denied |
The magic number is 740. Above 740, you typically qualify for the best rates lenders offer. The difference between 700 and 760 on a $300,000 mortgage can be 0.5% in interest rate — roughly $30,000 over 30 years.
FICO scores are calculated from five factors, each weighted differently:
| Factor | Weight | What It Measures |
|---|---|---|
| Payment history | 35% | Do you pay on time? |
| Amounts owed | 30% | Credit utilization ratio |
| Length of credit history | 15% | How long accounts have been open |
| Credit mix | 10% | Variety of credit types |
| New credit | 10% | Recent applications and new accounts |
Payment history and credit utilization together account for 65% of your score. These are the two most powerful levers you have.
Credit utilization is the percentage of your available credit that you're currently using. If you have $10,000 in total credit limits and $3,000 in balances, your utilization is 30%.
For the best scores, keep utilization below 30% — and ideally below 10%. Paying down credit card balances has an immediate impact on your score, often within one billing cycle.
Example: You have a $5,000 credit limit and carry a $2,000 balance (40% utilization). Paying it down to $400 (8% utilization) could improve your score by 30-50 points within 30-60 days.
| Action | Time to See Impact | Potential Gain |
|---|---|---|
| Pay down credit card balance | 1-2 billing cycles | 20-50 points |
| Dispute and remove error | 30-45 days | Varies widely |
| Set up autopay, no missed payments | 6-12 months | 10-40 points |
| Reduce utilization below 10% | 1-2 months | 30-60 points |
| Build 2+ years of clean history | 24+ months | 50-100 points |
Here's what a better credit score means in real dollar terms on a $300,000 30-year mortgage:
| Credit Score | Estimated Rate | Monthly Payment | Total Interest |
|---|---|---|---|
| 760+ | 6.5% | $1,896 | $382,160 |
| 700-759 | 6.9% | $1,977 | $411,720 |
| 660-699 | 7.4% | $2,079 | $448,440 |
| 620-659 | 8.1% | $2,225 | $501,000 |
Moving from a 660 to a 760 credit score saves $183 per month and $118,880 over the life of the loan on a $300,000 mortgage. That's why improving your credit score before applying for a mortgage is one of the highest-ROI financial moves you can make.
