Which strategy is usually best for saving money?

Avalanche usually saves the most interest because it overpays the highest APR debt first. But the best strategy is the one you can follow every month.

What counts as real data in this tool?

Your debt inputs are real data. The tool can also use live UK sources such as Bank of England base rate and Postcodes.io region lookup for context.

What counts as an estimate?

Debt-free dates and total interest are estimates based on your inputs and the assumption that payments stay consistent each month.

Can I trust the payoff month?

Use it as a planning estimate. It is reliable when your APR and payments stay stable, but real lender changes can move the date.

Can I export the plan?

Yes. You can export strategy results as CSV and review them later.

Quick Tips

Jump-start your understanding with these essential tips

Enter the latest balance, APR and minimum payment from each statement. Real values give far better results than memory-based estimates.

Run a second scenario with a lower or higher overpayment amount so you can see how sensitive your debt-free date is.

Update the tool after rate changes, balance transfers or income changes to keep your plan realistic.

Step-by-Step Guide

Follow these steps to get the most from this tool

For each debt, enter the current balance, annual interest rate (APR), and minimum monthly payment. If one of these is missing, your plan can be misleading.

💡 Pro Tips:

•Keep debt names clear so you can action the plan quickly.
•If your APR is variable, update it when your lender changes it.

The planner calculates all three strategies from the same inputs. You can compare total interest, debt-free date, and monthly pressure before picking one.

💡 Pro Tips:

•Avalanche usually saves the most interest.
•Snowball can feel easier to stick with because smaller debts clear earlier.

Set up your overpayment on payday and keep minimums active for all debts. Re-run the tool if your budget changes so your next payment order stays optimal.

💡 Pro Tips:

•Export CSV to keep a record.
•Pair this with your monthly household budget review.
