Your debts

Debt 1

Leave blank to pay just the minimum.

No minimum to enter: card minimums are worked out the way most issuers set them — 1% of the balance plus that month's interest, $25 at least — and recalculated every month as the balance falls.

Debt 2

Up to 15 debts. A blank row is ignored.

Anything you can pay on top of the minimums above.

Strategy

Highest rate first. The least interest.

Snowball or avalanche makes no difference here. Your extra payment does: $10,709 less interest and 228 months off the plan.

Snowball or avalanche?

The snowball pays the smallest balance first

You keep paying every minimum, then put every spare dollar on the debt with the smallest balance. When it clears, its payment joins the pile and moves to the next smallest one. Balances disappear quickly early on, and that is the point: the plan you keep doing beats the plan that looks best on paper.

The avalanche pays the highest rate first

Same rolling payment, different target: whatever charges the most interest goes first, however much it owes. That always costs the same or less than the snowball, and usually finishes at least as soon. The catch is patience — a big, expensive loan can sit at the top of the list for a year before anything gets crossed off.

The gap between them is usually smaller than the extra

Run both above with your own numbers. On most real debt loads the difference between the two orders is a few hundred dollars, while another $100 a month is worth thousands. Pick the order you will actually stick to, and spend the argument on finding the extra instead.

What a minimum payment actually does

A credit card minimum is usually about 1% of the balance plus that month's interest, with a floor near $25 — and it falls every month as the balance does. That is the trap: the payment shrinks as fast as the debt, so a $6,000 card at 24.99% APR starts around $185 a month and is still going more than twenty years later, having cost more in interest than the balance you began with. A loan is the opposite. Its payment is fixed, so the same amount buys more principal every month and the end date is set from the start. This page treats the two differently for exactly that reason: it asks a loan what you pay, and works a card's minimum out for you, month by month, the way your issuer will. Anything above the minimum goes straight at the principal, and it compounds — it lowers next month's interest, which lowers the month after that. That is the whole trick, and it is why this page asks for the extra before it asks for anything else.

When a payment can't cover its own interest

If what you pay is less than the interest a debt charges that month, the balance goes up, not down. This calculator says so, per debt, instead of quietly projecting a payoff date that will never arrive.

Promotional rates and deferred interest

A 0% promotional rate is not modelled on this page: enter the rate you'll pay when it ends, and treat the date as optimistic until then. Inside the app, a debt can carry a promotional APR with an end date, and the plan switches to the regular rate on that date. Deferred interest — where the whole period's interest lands at once if you don't clear the balance — isn't the same thing as 0%, and neither this page nor the app models it.

Questions

Is it really free? Do I need an account?
It is free and there is no sign-up. The math runs in your browser, so nothing you type is sent anywhere — there is no server to send it to. An account is only useful afterwards, if you want the plan kept up to date as you pay things down.
Which is better, the snowball or the avalanche?
The avalanche never costs more interest, so on paper it wins. The snowball crosses debts off sooner, which is what keeps most people going. Both are shown above with your own numbers, so you can see what the choice is actually worth to you.
Why doesn't it ask for my credit card's minimum?
Because a card's minimum isn't a fixed number. It's roughly 1% of the balance plus that month's interest, recalculated every statement, so it falls as the balance falls. Entering today's figure and holding it flat would flatter the answer by years. A loan is the other way round — its payment is fixed, so that one it does ask for. If you pay a card more than the minimum each month, there's an optional field for that.
Does it handle car loans, student loans and medical debt?
Yes. Any debt with a balance, a rate and a monthly payment fits. Mortgages work too, though a payoff plan that includes one usually says more about the mortgage than about everything else.
Is this the same calculator the app uses?
The same simulation, the same code. Save the plan and the date on your dashboard is the date you saw here.
