What the Calculator Shows You

  • Your debt-free date - the exact month and year you'll make your final payment, based on a month-by-month simulation of your real numbers.
  • Total interest cost - exactly how much interest you'll pay over the full repayment, and how much you'd save by adding extra each month.
  • Which debt to attack first - snowball (smallest balance) or avalanche (highest APR) - the calculator picks based on your chosen method.

3 Steps to Your Debt-Free Date

  1. Enter each debt - name, balance, APR, and minimum payment. Credit cards, loans, overdrafts, BNPL.
  2. See the timeline - your debt-free date, total interest, and which debt to target first.
  3. Adjust extra payments - slide to see how £25, £50, or £100/month changes your date.

What Extra Payments Actually Do

Example: £10,000 total debt across 3 credit cards at average 22% APR.

  • Minimums only: 11+ years, £8,200 in interest.
  • + £100/month extra: 3.5 years, £3,100 in interest. Save £5,100.
  • + £200/month extra: 2.5 years, £2,100 in interest. Save £6,100.

Illustrative. Your actual numbers depend on your specific debts, APRs, and payments. Use the calculator for your real timeline.

Frequently Asked Questions

How do I calculate my debt-free date?

Enter each debt's balance, APR, and minimum payment into a debt-free date calculator. It runs a month-by-month simulation showing exactly when your last payment clears. With TrySnowball, this takes under 2 minutes and includes snowball, avalanche, or custom strategies.

How long does it take to pay off £10,000 in debt UK?

It depends on your interest rates and monthly payments. At 20% APR paying only minimums, £10,000 could take 10+ years and cost over £8,000 in interest. Adding just £100/month extra cuts that to around 4 years and saves thousands. Use our calculator to see your exact timeline.

Is the debt-free date calculator free?

Yes, completely free with no signup required. Enter your debts, see your debt-free date instantly. If you want to save your plan and track progress over time, you can optionally create a free account.

What's the fastest way to become debt-free in the UK?

The debt snowball method (paying smallest debts first) has the highest completion rate because of psychological momentum. The debt avalanche method (highest APR first) saves more interest mathematically. Both beat making only minimum payments. The best approach is the one you'll stick with - the calculator shows both so you can compare.

Does the calculator work for UK BNPL and overdrafts?

Yes. Any UK debt with a balance, APR, and minimum payment can be modelled - credit cards, personal loans, overdrafts, store cards, and BNPL agreements like Klarna or Clearpay.

If your minimum payments alone are out of reach, free debt advice helps more than a calculator can. These UK charities offer free, confidential support:
