The Three-Year Personal Loan

What 36 months costs at common amounts

Fixed rate, equal monthly payments and no fees: the table gives the monthly payment and, in brackets, the total interest over the three years. These are worked examples, not offers. Your own rate depends on your credit, your income and the lender.

Every five points of APR adds roughly $25 a month per $10,000 borrowed over three years. Pick the amount first, then use the payment by loan size calculator to test the rates you are actually offered.

36 months against shorter and longer terms

The trade is always the same: fewer payments mean bigger ones and less interest. Here is $15,000 at a 15% APR across four common lengths.

Going from 36 to 24 months raises the payment by about $207 and saves about $1,264. Going from 36 to 60 lowers it by about $163 and costs about $2,692 more. Lenders also tend to price longer terms higher, which widens the gap: the figures above hold the rate equal for all four terms. The loan term comparison lays out every length side by side for your own amount.

Three rings: what each year of the loan does

A three-year loan grows three rings, and they are not equal. In the first year of $10,000 at 15% APR, you pay $4,159.84 and $1,309.30 of it, about 31%, is interest; the balance falls to $7,149.46. In the second year interest takes about 20% of what you pay, and in the third year about 8%. The principal you repay grows each year: $2,850.54, then $3,308.78, then $3,840.68.

That shape matters for two decisions. Extra payments do the most good in the first ring, when the balance and the interest on it are highest. And refinancing in the third year rarely saves much, because most of the interest has already been paid; a fee on the new loan can cost more than the interest left on the old one.

When three years is the right length

• The payment fits with margin. If the 24-month payment would leave you short in an ordinary month, 36 months buys room without doubling the interest.
• The thing you pay for lasts longer than the loan. A repair, a move or consolidated card balances are gone or settled long before year three ends; you are not still paying for them years later.
• You want a set end date. Unlike a credit card balance, a three-year installment loan is paid off on a known date if you make every payment.

Thirty-six months is a poor fit when the payment only works because the amount was stretched to cover things you do not need, or when your income will drop soon. In the first case, borrow less; in the second, a longer term with extra payments when you can afford them keeps the required payment low. Choosing a term for your amount walks through the decision.

Who offers 36-month loans

Almost every personal lender does: banks, credit unions, online lenders and licensed finance companies all treat three years as a standard term. The Federal Reserve tracks bank personal loan pricing with a 24-month loan rather than a 36-month one; its survey of commercial banks put that average APR at 11.90% for the third quarter of 2026. Expect three-year offers from the same bank to be priced near that level, and higher from lenders that approve weaker credit.

Reading a 36-month offer

1. 1 Check the number of payments. The Truth in Lending disclosure lists it; it should say 36, and the payment schedule should show when the first one is due.
2. 2 Look at the amount financed. If an origination fee is taken out, it will be lower than the loan amount, and the APR will be above the interest rate.
3. 3 Read the finance charge. It is the dollar cost of the loan over all 36 months, including the fee; set it against the same figure on any 24- or 48-month offer.
4. 4 Confirm the payment date. Ask to move it to a few days after payday if the first one falls just before.

Paying a 36-month loan off sooner

On a simple-interest loan, any extra payment goes to the balance and stops interest on that amount for the rest of the term. Most personal loans have no prepayment penalty, but some do; it must be shown in the loan disclosures. Ask the lender to apply extra payments to principal and confirm it on your next statement. Even one extra payment a year shortens a three-year loan by a few months and trims the interest of the last ring.
