Paying off a credit card in 12, 24 or 36 months: monthly payment and total interest

The rate we used and why

The Federal Reserve's G.19 consumer credit release, published October 7, 2026, reports commercial bank interest rates on credit card plans. For Q2 2026 it shows 22.15% on accounts assessed interest and 20.94% on all accounts. We use 22.15% as the central case because it reflects cards that actually carry a balance, and 28% as a higher example rate for store cards, fair-credit cards or penalty pricing. Neither number is your rate; use the purchase APR on your statement.

Method: fixed monthly payment, interest at APR / 12 per month, no new purchases, no fees, no rate changes. Issuers compute interest daily on the average daily balance, so your figures will differ by a few dollars. Rounding to the cent is ours.

$12,000 balance

The pattern is the same at every size: stretching from 12 to 36 months cuts the monthly payment by about 60% but roughly triples the interest. On $12,000 at 22.15%, the 36-month plan costs $3,043.83 more interest than the 12-month plan. At the all-accounts average of 20.94%, the 12-month payment would be $1,117.02 with $1,404.24 of interest.

Choosing a timeline you will finish

Pick the shortest plan whose payment fits after essentials and a small emergency buffer. A plan you abandon in month five costs more than a slower plan you finish. Two rules help. First, stop using the card you are paying down: the CFPB says that when you carry a balance, new purchases generally accrue interest from the day they are made. Second, if you have several balances on one card, Regulation Z section 1026.53 sends any amount above the minimum to the highest-APR balance first, so a cash advance balance gets cleared before purchases.

Compare your plan with the minimum payment warning on your statement. Regulation Z requires it to show the monthly payment that would pay the balance off in 36 months along with the total cost and the savings versus paying the minimum. If your chosen payment is lower than that 36-month figure, your plan is slower than three years.

• Write the balance, APR and minimum from the latest statement.
• Pick 12, 24 or 36 months from the tables and round the payment up to the next $5 or $10.
• Set autopay for that fixed amount, a few days before the due date.
• Re-check the balance every three months; a lower rate or a windfall lets you shorten the plan.
• If you have more than one card, decide the order using our avalanche-or-snowball guide.

Putting the plan into a budgeting app

A payoff plan works when the payment is treated as a bill, not as whatever is left. YNAB's debt page describes organizing a payoff plan and experimenting with its Loan Planner, and offers training on building a debt paydown plan. YNAB lists $14.99 a month or $109 a year, with a 34-day free trial and a free 365-day trial for college students.

Monarch's public debt payoff calculator takes each debt's balance, minimum payment and interest rate plus a total monthly debt budget, compares avalanche and snowball, and returns a payoff timeline, total interest and a debt-free date. Monarch says only members get its debt calculator that uses historical data. Inside the app, Monarch's planning page says you can create goals with a target amount and planned monthly contribution, including paying off credit card debt. Monarch lists $14.99 a month or $99.99 a year, and its pricing page says the first week is free.

A spreadsheet works too: one row per month with starting balance, interest at APR / 12, payment and ending balance reproduces the tables above. The app's advantage is that the payment sits next to your other spending each month.
