Frequently Asked Questions
Is the Debt Avalanche always better?
Mathematically, yes. The Avalanche method will *always* save you the most money because it eliminates the most expensive debt first. However, personal finance is personal. If the Snowball method keeps you motivated to not quit, then it is the 'better' method for you.
Should I include my mortgage in this calculator?
We recommend excluding your mortgage unless you are aggressively trying to pay it off early. Mortgages are generally low-interest 'good debt' that stretches over 30 years. This calculator is best suited for high-interest consumer debt like credit cards (20%+) and personal loans.
What is a 'Minimum Payment'?
This is the lowest amount your lender requires you to pay each month to avoid late fees. Paying only the minimum is a trap—it often barely covers the interest, keeping you in debt for decades. This calculator assumes you pay the minimums on all debts, plus a specific 'Extra Payment' allocated to one target debt.
How do I find my interest rates?
Check your latest monthly statement from your lender. It will be listed as 'APR' (Annual Percentage Rate). For credit cards, it is often found in the fine print at the end of the statement.
