How the payment is calculated

Each payment is the standard amortized-loan amount: the $15,000 principal, the monthly rate (APR ÷ 12), and the number of months determine a fixed payment where early payments are mostly interest and later ones mostly principal. Total interest is the sum of the interest portion across every scheduled payment. See the amortization explainer on the home page for the formula.

Getting the rate down

On $15,000, moving from 24% to 12% APR over five years saves about $5,643 in interest. That gap is mostly credit score and, to a lesser extent, shopping several lenders within a two-week window so the hard inquiries count as one. If you are consolidating card debt, model the payoff both ways with the debt payoff calculator.

Frequently asked questions

What is the monthly payment on a $15,000 personal loan?

At 12.5% APR it is about $337.47 a month over 60 months, or $501.80 a month over 36 months. A lower APR or a longer term lowers the monthly payment; a longer term raises the total interest. The table above shows every combination.

How much interest will I pay on $15,000 over 5 years?

About $5,248 at 12.5% APR. At 24% APR the same loan costs roughly $10,891 in interest — credit score is the biggest lever on that number.

Can I get a $15,000 personal loan with bad credit?

Often yes, but expect an APR near the top of the 36% range and possibly an origination fee of 1–8%. Compare the APR (which includes the fee), not the nominal rate. If the payment looks unaffordable, a longer term or a smaller amount helps more than shopping for a slightly lower rate.

$15,000 loan over 3 years or 5 years?

Three years means a higher monthly payment ($501.80 vs $337.47 at 12.5% APR) but less interest overall. Five years is easier on the monthly budget but you pay more to borrow. Pick the shortest term whose payment you can comfortably cover every month.

Does the payment include an origination fee?

The table assumes no fee. If a lender charges one, add it to the amount borrowed: a 5% fee on $15,000 is $750, so you would run the numbers on $15,750. The main calculator below has an origination-fee field.

Can I pay a $15,000 loan off early?

Most personal loans allow early payoff with no penalty, which saves the remaining interest. Check the agreement for a prepayment clause. Extra payments go entirely to principal once the month's interest is covered.
