Debt Avalanche Calculator
The avalanche method targets your highest interest rate first, which usually reduces the total interest you pay. It can take longer to clear the first debt, so it suits people who are motivated by the maths rather than early wins.
If things are urgent right now
If you have missed rent, mortgage, energy, tax or court-ordered payments, are facing eviction or enforcement action, cannot afford food, or you are having thoughts of harming yourself, please speak to a person — not a calculator. Free, confidential and qualified debt advice exists in most countries, and using it does not harm your credit file.
How I Cleared My Debts provides educational information, organisational tools and estimates. It does not provide personalised financial, legal, tax or regulated debt advice. Results depend on the information you enter and may not reflect lender calculations. If you are struggling with priority bills, legal action or unaffordable repayments, contact a qualified free debt-advice organisation in your country.
Debt Avalanche Calculator does not recommend any specific regulated debt solution and does not assess affordability on your behalf.
