Choosing a Debt Repayment Strategy
The Debt Avalanche method is a mathematically optimized approach. By theoretically targeting the debt with the highest APR first, you aim to minimize the total interest paid over the life of your debts. Conversely, the Debt Snowball method prioritizes psychological momentum; by clearing smaller balances first, you create "quick wins" that can help maintain long-term motivation.
This UK debt calculator uses a standard compounding interest formula to simulate how additional monthly contributions can accelerate your debt-free journey. Whether you are managing credit cards, personal loans, or car finance, seeing a projected debt-free date can be a powerful tool for intentional spending and financial planning.
