You Don’t Have a Debt Problem. You Have a Missing Date.
Nobody panics about the balance. They panic about not knowing when it ends. That gap — the not-knowing — is what keeps people paying minimums for years without ever checking if there’s a faster way out.
The average UK cardholder is carrying £2,601 at 24.65% APR right now — a rate the Bank of England hasn’t recorded this high in over three decades. In the US it’s $6,715 per person at 21.52% APR, according to TransUnion and the Federal Reserve. Neither number moves on its own. It sits there compounding, silently, for every month there’s no plan attacking it.
This debt payoff calculator gives you that date in under two minutes. Enter what you owe, on what, at what rate, and what you can actually put toward it each month — it runs the exact amortisation maths lenders use internally, including any extra payments you plan to make, and hands back a real month you’ll be debt-free. Not a guess.
It tests three strategies against your numbers — Avalanche (highest interest rate first, saves the most money overall), Snowball (smallest balance first, gets you a win fastest), and Smart Focus (an AI-weighted blend of both) — then charts which one gets you free soonest and what each one actually costs you in interest. Multiple debts, GBP, USD, or CAD — all handled in one run.
Unlike a debt payoff spreadsheet you have to keep rebuilding by hand, or an app that wants your bank login before it’ll tell you anything, this recalculates the second you change a number — no account, no download, no card details.

What Your Results Actually Mean
Your debt-free date isn’t a prediction — it’s arithmetic. The calculator runs standard amortisation, the same maths banks use internally, against the exact numbers you entered. Change your real minimum payments, your APR, or an extra payment plan, and the date moves with you. It’s only ever as accurate as what you put in.
Two moves make the biggest difference from here. First, try the What If simulator above — even £50 or $50 extra a month can strip years off a high-APR balance. Second, if your result shows minimum payments are barely denting the total, take that seriously: our Minimum Payment Trap Calculator breaks down exactly how much of every payment is going to interest versus your actual balance.
If you’re in the UK and this plan still shows years of repayment ahead on unmanageable balances, an IVA or the government’s Breathing Space scheme could change the maths entirely — read what an IVA actually involves, how Breathing Space works, or check the DRO eligibility checker if your total debt is under £50,000. In the US, if the numbers don’t work even with a tighter budget, look at what a negotiated settlement could realistically save you with the Debt Settlement Calculator before assuming bankruptcy is the only door left.
Paying off debt also moves your credit score — usually upward, once your utilisation drops. See how with the AI Credit Score Roadmap. For the wider strategy, start with the US debt payoff hub or the step-by-step payoff plan guide if you’re UK-based.

Questions People Actually Ask About This
Is this debt payoff calculator actually free?
Yes — no account, no card details, no cap on how many times you run it. Change your budget, add a debt, test a strategy, rerun it as many times as you want. There’s no premium tier hiding behind it.
How accurate is the debt-free date this gives me?
As accurate as what you enter. It runs the same amortisation formula lenders use internally — balance minus payment plus interest, month by month, until it hits zero — assuming your APR, minimum payments, and monthly budget stay constant. If your real rate changes or a month gets tight, rerun the numbers and the date updates with them.
Can I save my numbers and come back to them later, like a tracker?
Not right now — every run is free and unlimited, but nothing is stored on our end once you close the tab. If you want a record, screenshot your results or copy the numbers into a note. We’d rather tell you that upfront than have a spreadsheet-style “tracker” claim that isn’t true.
What’s the difference between the Avalanche and Snowball method?
Avalanche throws every spare pound or dollar at your highest-APR debt first, regardless of size — mathematically it always saves you the most in total interest. Snowball ignores the interest rate and clears your smallest balance first, so you finish a debt completely sooner — for a lot of people that’s the difference between sticking with a plan and giving up on it. Neither is wrong. The comparison table above shows the actual difference for your specific debts.
Will using this tool affect my credit score?
No — it’s a calculator, not a credit application, so it never touches your credit file and involves no search, hard or soft. What it does show is how paying down balances is likely to move your score over time, since credit utilisation — how much of your available credit you’re using — is one of the biggest factors most scoring models weigh.
What if I can’t even afford my minimum payments right now?
If your monthly budget doesn’t cover your total minimums, this calculator flags it rather than handing you a false date. That’s a sign the calculator alone isn’t enough — read what actually happens if you stop paying and know your rights before creditors or collectors get involved. Then talk to a free debt charity directly — StepChange in the UK, the NFCC in the US — rather than relying on a calculator alone.
What’s Smart Focus, and how is it different from Avalanche or Snowball?
Smart Focus ranks your debts by monthly interest cost — balance multiplied by rate — rather than pure APR or pure balance. In practice it usually lands between Avalanche and Snowball: it goes after whichever debt is bleeding you the most money right now, which is sometimes a mid-sized balance at a brutal rate rather than your single highest APR card. It’s a reasonable default if you’re not sure which of the other two suits you.
Does this tool report anything to my bank, lender, or credit file?
No. Nothing you enter is shared with any bank, lender, or credit reference agency — it stays in your browser for this session and isn’t saved anywhere afterward.
Can I use this if my debts are in more than one currency?
The tool calculates in one currency at a time — switch using the GBP, USD, or CAD buttons at the top. If your debts genuinely span currencies, run the calculation once per currency group and add the results together manually, since exchange rates fluctuate and this doesn’t convert between them.
