How much can a higher credit score save you?
On an average car loan, moving from near-prime to prime credit cuts the typical APR from 9.71% to 6.15%. That’s about $5,450 less interest over six years, or $76 a month.
The tables use the same loan amounts and national average rates as the calculator. Find your score band, then look at the row above it.
Car loan
| Score | Tier | APR | Monthly payment | Total interest | Extra vs. best tier |
|---|---|---|---|---|---|
| 781–850 | Super prime | 5.02% | $703 | $6,987 | — |
| 661–780 | Prime | 6.15% | $726 | $8,650 | +$1,663 |
| 601–660 | Near prime | 9.71% | $802 | $14,102 | +$7,114 |
| 501–600 | Subprime | 13.22% | $881 | $19,786 | +$12,799 |
| 300–500 | Deep subprime | 15.81% | $941 | $24,173 | +$17,185 |
Mortgage
| FICO® Score | APR | Monthly payment | Total interest | Extra vs. 760+ |
|---|---|---|---|---|
| 760–850 | 6.19% | $2,141 | $420,893 | — |
| 700–759 | 6.41% | $2,192 | $438,963 | +$18,069 |
| 680–699 | 6.62% | $2,240 | $456,375 | +$35,482 |

Car insurance
Insurance is a yearly premium, not interest. Insurify’s 2026 study puts the average at $1,720 a year for drivers with good or better credit (720+) and $3,180 for poor credit (300–579). It doesn’t publish averages for scores between 580 and 719.
California, Hawaii, Massachusetts and Michigan don’t let insurers use credit to set prices, so the calculator shows no savings for drivers there.
Why savings come in steps, not points
Lenders don’t price every point. They group scores into bands, and everyone in a band gets roughly the same rate.
That’s why going from 640 to 655 may save nothing on a car loan: both scores sit in the near-prime band (601–660). Cross 661 and the typical APR drops from 9.71% to 6.15%.
So the useful question isn’t “how many points can I gain?” It’s “how far am I from the next band?” If your goal lands in the same band as your current score, the calculator says so and suggests the nearest goal that changes your rate.
How the calculator works
It looks up the typical APR for your current score band and for your goal band, then works out the total interest on the same loan at each rate. The difference is your estimated saving.
M = P × r ÷ (1 − (1 + r)−n)
- M
- monthly payment
- P
- loan amount
- r
- monthly rate: the APR divided by 12, as a decimal
- n
- number of monthly payments
Total interest is M × n − P. Your saving is the total interest at your current APR minus the total interest at your goal APR, rounded to the nearest $10.
For a standard car loan or mortgage, dividing the APR by 12 gives the correct monthly rate. That’s different from investment returns, which compound.
Example: 640 to 681 on a car loan
- Take the average new-car loan: $43,610 over 72 months.
- At 640 (near prime), the typical APR is 9.71%, a monthly rate of 0.809%. The payment is $802 a month and total interest is $14,102.
- At 681 (prime), the typical APR is 6.15%, a monthly rate of 0.513%. The payment is $726 a month and total interest is $8,650.
- $14,102 − $8,650 is about $5,450 saved, or $76 less every month.
Which credit score should you enter?
Use the most recent score you have. Your bank, card issuer or a credit app usually shows one for free.
Lenders don’t all use the same scoring model. The mortgage rates here are grouped by FICO® Score and the car-loan rates by VantageScore® 4.0, so the score a lender pulls can differ from the one in your app. Treat the result as a guide.

Credit score ranges
Most scores run from 300 to 850. These ranges are a general guide; each lender sets its own cut-offs.
| Range | Score | What it usually means |
|---|---|---|
| Exceptional | 800–850 | Lenders’ best terms are likely |
| Very good | 740–799 | Strong rates on most loans |
| Good | 670–739 | Most lenders approve |
| Fair | 580–669 | Approvals possible, higher rates |
| Poor | 300–579 | Hard to qualify for most credit |
How to move up a band
No one can promise a score change, but some habits carry more weight than others. According to FICO, payment history makes up about 35% of a FICO® Score and amounts owed about 30%.
- Pay every bill on time. A payment 30 or more days late can stay on your report for up to seven years. More on payment history
- Keep card balances low compared with your limits. Lower is better; many people aim for under 30%. More on credit utilization
- Get your rent payments reported. Rent you already pay can add on-time history to your credit file. Vola rent reporting
- Get smart alerts and insights with CreditMap.
Frequently asked questions
How much does your credit score affect a car loan rate?
A lot, and in steps. In Experian’s Q2 2026 data, the typical APR is 9.71% for near-prime borrowers (VantageScore® 601–660) and 6.15% for prime borrowers (661–780). On a $43,610 loan over 72 months, that gap is about $5,450 in interest.
Will raising my score by 20 points lower my interest rate?
Only if it moves you into a better rate band. Lenders price scores in bands, so 20 points inside the same band usually don’t change your rate. Twenty points that cross a band line, such as 650 to 670 on a car loan, can.
What credit score do I need for a mortgage?
Most conventional lenders look for 620 or higher, which is why the mortgage rates in this calculator start at 620. Government-backed loans can have lower minimums. Rates keep improving as scores rise, with the best rates typically at 760 and above.
Does my credit score affect car insurance?
In most states, yes. Insurers can use a credit-based insurance score to help set your premium. California, Hawaii, Massachusetts and Michigan don’t allow it, so the calculator shows no savings for drivers there.
Why is my lender’s score different from the one in my app?
There are several scoring models and versions, and each credit bureau can hold slightly different data. A mortgage lender may use a FICO® Score while your app shows a VantageScore®. Small differences are normal.
How long does it take to raise a credit score?
It depends on what’s holding it down, and no one can guarantee a change. Lower card balances can show up after your issuer’s next report, usually monthly. Building on-time history takes longer, and late payments can stay on your report for up to seven years.
Does using this calculator affect my credit?
No. You type in your score yourself, so there’s no credit check of any kind.
Is the savings number an offer or a guarantee?
No. It’s an estimate based on national average rates for each score band. Your actual rate depends on the lender, your income and debts, the loan itself and more.
