Debt-Free Date Calculator
Name the deadline and get the payment. Enter every debt and the number of months you want to be free of them, and this solves for the smallest monthly payment — to the cent — that clears every balance in time.
Your debts and your deadline
Whole months from now, up to 360. The payment is solved to the cent for the deadline you set.
A month across all debts — $526.87 more than the $430.00 of minimums. The last payment lands in month 24.
- Total balances
- $20,200.00

| Plan | Monthly payment | Time to clear | Total interest |
|---|---|---|---|
| Your deadline | $956.87 | 2 years | $2,764.80 |
| Minimums only | $430.00 | 6 years, 8 months | $13,889.66 |
Hitting the deadline saves $11,124.86 in interest against paying only the minimums. Payoff order: Store card → Rewards card → Car loan.
What other deadlines cost each month
Why the payment is searched for rather than solved
A single loan has a closed-form payment: the standard annuity formula inverts cleanly. A set of debts paid in an order does not. How much interest the plan accrues depends on which debt the surplus happens to be sitting on when each of the others clears, and that depends on the payment you are trying to find. So the payment is found by search instead.
The calculator simulates the plan month by month: interest accrues on every balance at one twelfth of its APR, every minimum is paid, and the whole remainder goes to the debt the strategy names — highest APR, or smallest balance. Freed-up payments roll forward. Candidate payments are tested in whole cents, halving the search range each time, until the smallest amount that clears everything by your deadline is found. Testing in cents is what makes the answer exact: a cent less genuinely misses the date.
Floor = Σ minimums; Ceiling = Σ balances × (1 + highest monthly rate) + Floor- Floor
- Nothing below the minimums is a payment plan
- Ceiling
- Enough to clear everything in a single month
- Search
- Bisection on whole cents between the two
If the minimums alone already beat your deadline, the minimums are returned — there is no honest way to ask for less. And if the minimums never clear the debts at all, that path is reported as having no payoff date rather than a fabricated one.
$20,200 of debt gone in two years
Take a $6,000 store card at 24.99% APR (minimum $120), a $3,200 rewards card at 18.5% (minimum $70), and an $11,000 car loan at 8.9% (minimum $240): $20,200 owed against $430 of minimums. To be debt-free in 24 months paying the highest rate first, the required payment is $956.87 a month — $526.87 above the minimums. The plan costs $2,764.80 in interest and clears the store card, then the rewards card, then the car loan.
Paying only the $430 of minimums, the same debts take 80 months and cost $13,889.66 in interest. The deadline therefore saves $11,124.86 in interest and more than four and a half years.
Moving the deadline moves the payment far more than it moves the interest. Twelve months needs $1,796.61 a month and costs $1,359.22 in interest; 24 months needs $956.87 and costs $2,764.80; 36 months needs $684.22 and costs $4,431.76. Each extra year takes several hundred dollars off the monthly figure and adds between $1,400 and $1,700 of interest — the trade-off worth understanding before committing to any of them.
What this calculator assumes
- Every APR is fixed for the whole payoff period.
- Minimum payments are fixed dollar amounts. Real card minimums fall as the balance falls.
- The required payment is paid in full every month, starting this month, with no missed or partial payments.
- Interest accrues monthly at one twelfth of the APR, before payments are applied.
- Freed-up payments roll onto the next target debt, keeping the total monthly outlay constant.
- No new charges, fees, or rate changes. Money values are rounded to the nearest cent for display.
Understanding the Debt-Free Date Calculator
Most debt calculators ask what you can pay and tell you when you will finish. This one runs the other way: you name the date, and it solves for the monthly payment that gets you there. That is the question people actually ask — out before the lease renews, before the baby arrives, before the wedding — and it is the harder one, because a set of debts paid in an order has no closed-form answer.
The payment is found by searching, to the cent, for the smallest total monthly amount that clears every balance by your deadline. Below it sits the same plan under the minimums alone, so you can see what the deadline is costing you each month and what it is saving you in interest.
Who this calculator is for
- Anyone with a date in minda wedding, a move, a career change — who needs the payment that reaches it.
- People negotiating with themselves about a budgetwho want to know exactly how much the ambitious deadline costs per month.
- Couples agreeing on a planwho need one number to commit to rather than a vague intention.
- Anyone paying minimumswho wants to see the gap between the minimum path and a deliberate one.
- People preparing for a mortgage applicationwho need consumer debt gone by a specific point in the process.
Why it matters
- It answers the question in the form people ask it: a date in, a payment out.
- It solves to the cent rather than rounding to a comfortable number, so the figure shown genuinely meets the deadline and a cent less genuinely does not.
- It shows the same debts under minimums alone beside your plan, which is usually the most persuasive number on the page.
- It reports the payoff order, so you know which account the extra money is actually attacking each month.
- It compares a one-year, two-year, and three-year deadline at a glance, which turns an abstract ambition into a monthly figure you can test against your budget.
How to use this calculator
- List every debt with its balance, APR, and required minimum payment.
- Enter the number of months you want to be debt-free in.
- Choose the payoff order: highest APR first costs the least interest, smallest balance first clears whole accounts sooner.
- Read the required monthly payment, and the amount of it that sits above your minimums.
- Compare it against the one-year, two-year, and three-year cards. If the payment is out of reach, move the deadline rather than abandoning the plan.
How to read your result
The headline is the total you must pay across all debts each month to finish on time — not per debt, and not on top of the minimums. The figure beneath it separates out the part above your minimums, which is the money you have to find. If that number is uncomfortable, the comparison cards show what a longer deadline asks for instead; the relationship is not linear, and moving from one year to two often halves the payment while adding far less than double the interest.
The minimums-only row is the honest counterfactual. It is what happens if nothing changes, and on most debt sets it is measured in years rather than months, with an interest figure several times larger. If it reads 'never at the minimums', your required minimum payments do not cover the interest being charged — the deadline payment is not an optimisation in that case, it is the only path that ends.
- The payment is the total across every debt, including the minimums, not an extra on top of them.
- Every APR is assumed fixed. Variable rates move with prime, and a missed payment can trigger a penalty rate that makes the deadline unreachable at the payment shown.
- New charges break the plan. The model assumes nothing further is added to any balance.
- Minimum payments are treated as fixed dollar amounts. Real card minimums fall as the balance falls, which changes the shape of the plan slightly.
- A deadline you cannot sustain is worse than a longer one you can. The calculator will happily solve for a payment your budget cannot support.
- Clearing consumer debt before a mortgage application affects your ratios, but lenders look at the whole file. Use the debt-to-income calculator alongside this one.
- Set the deadline first, then check the payment against your actual budget rather than the other way round — it is the only order that produces a plan you keep.
- Automate the minimums and move the extra by standing order on payday, so the plan does not depend on willpower at the end of the month.
- Re-run it whenever your income changes. The payment is a target, not a contract, and a raise usually buys months rather than dollars.
Frequently asked questions
How is the required payment calculated?
By search, not by formula. A set of debts paid in an order has no closed-form solution, because which debt the surplus sits on when each one clears changes the interest. The calculator tests candidate payments in whole cents, narrowing until it finds the smallest one that clears every balance by your deadline.
Why can't the payment be lower than my minimums?
Because paying below a required minimum is a missed payment: it triggers fees, can trigger a penalty APR, and is reported to credit bureaus. The sum of your minimums is the floor of any real plan, and if it already beats your deadline, that sum is what the calculator returns.
Should I choose highest APR or smallest balance first?
Highest APR first — the avalanche — always costs less interest for the same payment. Smallest balance first — the snowball — clears whole accounts sooner, which many people find easier to stick with. The snowball vs. avalanche calculator prices the exact difference for your debts.
What does 'never at the minimums' mean?
It means the interest charged each month is at least as large as the sum of your minimum payments, so the balance never falls. There is no payoff date and no total cost to report for that path. The deadline payment shown is not an improvement on it — it is the difference between a debt that ends and one that does not.
Does the calculator account for the payment I free up as debts clear?
Yes. Your total monthly payment stays constant, so as each debt is cleared its share rolls onto the next target. That rolling effect is why the last debts fall much faster than the first, and it is already built into the required payment.
Are my inputs saved or shared?
No. Every calculation runs in your browser; nothing is stored on our servers or sent to analytics. A shareable link only encodes the numbers you choose to share.
Before you commit to the payment
The payoff order matters as much as the amount — the snowball vs. avalanche calculator prices both orders against each other. If the required payment is out of reach, see what the minimum payment trap costs by comparison, or whether a consolidation loan changes the arithmetic. And if the reason for the deadline is a mortgage application, the debt-to-income calculator shows the ratio lenders will actually read.
