What interest rate can I expect with a 550 credit score?

Expect a subprime rate, and expect the lender to matter as much as the score. The Federal Reserve found that subprime borrowers paid a weighted average of about 14.6% APR at traditional lenders, meaning banks, credit unions and finance companies, and 25.4% at buy-here-pay-here dealers, on loans made from 2018 through the third quarter of 2025.

Rates: Federal Reserve, FEDS Notes, May 2026, weighted averages for subprime borrowers on loans made from Q1 2018 through Q3 2025. Payments computed on $15,000 over 60 months.

Same score, same loan amount, $90 a month apart. The Fed's averages span several years and do not break out individual scores, so read them as the gap between lender types rather than as a quote.

For the market as a whole, Experian's Q1 2026 used-car averages bracket a 550: 11.43% across all borrowers and 21.6% for deep subprime, the tier directly below. Your own offer moves with the down payment, the term, the vehicle and which lender sees the file.

If a lot is offering in-house financing at 550, see what a credit union or the dealer's outside lenders will do with the same file first. On the Fed's averages, that check is worth $90 a month on a $15,000, 60-month loan.

Is a 550 credit score subprime or deep subprime?

Both, depending on whose scale you use, and that is why the rates you find for "a 550" disagree. On Experian's scale, used in its quarterly auto finance reports, 550 is subprime. On the scale the Federal Reserve uses with New York Fed and Equifax credit data, anything below 580 is deep subprime, so 550 lands there.

Neither label is your rate. A lender prices from its own program tiers, so what matters is which program your file lands in, and the down payment and income behind it.

Is the rate lower on a new car with a 550 score?

Usually, yes: new-car rates run below used-car rates at every tier. In Q1 2026, Experian put the average at 6.39% new versus 11.43% used across all borrowers, and 15.85% new versus 21.6% used for deep subprime, the tier just below 550.

A lower rate on a newer car does not make it the cheaper deal. The bigger loan can still cost more in total, so compare the total of payments on both contracts, not the APR alone.

How does a 550 compare with a 500 or a 600?

A 550 sits in the middle of Experian's subprime tier, and that changes what is worth doing about it. In Q4 2025, Experian's used-car averages by tier were:

Experian, Q4 2025.

A 500-score borrower is one point from the subprime tier. A 600-score borrower is one point from near prime. Both of those people can sometimes buy a whole tier with a single point, which makes waiting a reporting cycle a defensible plan.

At 550 you are 49 points above the deep-subprime line and 51 points below the near-prime line. Nothing happens at 555, 560, or 575. You are priced identically across that whole stretch.

Rates: Experian, Q4 2025. Payments computed on a $15,000 loan over 60 months.

The practical reading: a 550 borrower who waits three months for a handful of points has usually bought nothing. The same three months spent adding to the down payment buys something measurable.

Approval is normal at this score. Subprime lenders are built for the 501 to 600 range, and most declines here are not score declines: the file did not support the payment.

What does a 550 car loan cost per month?

At 18.86%, the Q4 2025 subprime used-car average, a $15,000 loan over 60 months costs $388 a month.

Principal and interest at 18.86% APR, the Experian subprime average for Q4 2025.

Insurance is not in there, and at this score it is often a larger monthly line than buyers expect. Get a real quote on the specific vehicle before you agree to a payment, not after.

Total cost matters more than the monthly figure. A $15,000 loan at 18.86% over 60 months means repaying $23,277. Stretching the same loan to 72 months drops the payment to $349 and pushes total interest to $10,160.

What actually moves the deal at 550?

The score is fixed in the short run. These are not.

Down payment. This is the lever with the clearest arithmetic behind it.

Same vehicle, $2,000 more down. Rate: Experian subprime average, Q4 2025.

Two thousand dollars down takes $52 off the payment and $1,103 off the interest, and it also cuts loan-to-value, which is what the lender is actually underwriting. Typical subprime down payments run $1,000 to $2,500. See how much to put down on a car loan.

Documented income. Most subprime programs want proof of $1,500 to $2,000 a month from one primary source, and they cap payment-to-income somewhere around 15 to 20%. A second job that has been running two months usually does not count yet.

Which lender sees the file. Two lenders can price the same 550 differently on the same day, because their programs, their tier cutoffs, and their appetite for used collateral differ. This is the least visible variable and one of the largest, as the Fed's 14.6% and 25.4% averages show.

The vehicle. Older, higher-mileage collateral prices worse. A slightly newer car with a slightly better rate sometimes lands cheaper in total than the older car it seemed obvious to buy.

Should you wait to buy?

Here is the case against waiting, which is unusual for us to make.

At 600 we tell people to wait, because one point is worth 4.75 percentage points of APR. At 550 that argument does not exist. There is no boundary within reach, and the credit-building work that would take you to 601 typically takes longer than a car search does.

The exception is a specific, fixable problem: a maxed-out credit card, a collection you can validate as an error, a reporting mistake. Utilization updates monthly, and clearing a card near its limit can move a score materially in one cycle. Nobody can remove accurate information from your report, and any service claiming otherwise is selling something.

If you have no specific fix and you need the car, buying now and refinancing later is generally the stronger plan than waiting for a score that is not moving.

Is refinancing worth more than negotiating at 550?

Usually, yes. A borrower who signs at 18.86% and pays on time for twelve months frequently reaches near prime, because the auto loan is producing fresh positive history while the older damage ages.

Moving from 18.86% to 14.11%, the Q4 2025 subprime and near-prime averages, saves $38 a month on a $15,000 balance over 60 months, or $2,284 across the term. That is more than most buyers extract from haggling, and it requires no negotiation at all.

Nobody at the dealership will bring it up, because the refinance is somebody else's transaction. Put a reminder at eleven months and read when you can refinance after bad credit.

What will the lender ask for at 550?

Recent consecutive pay stubs, proof of residence, proof of insurance, references, and employment verification: the standard stips. Having them assembled before you shop is what keeps an approval from stalling at the desk.

One thing to refuse: solving an unaffordable payment by stretching the term to seven years. See what an 84-month car loan actually costs before anyone in a finance office suggests it.
