Paying Off Debt: the big picture
Paying off debt is not just about paying the minimum — it's about the order, the extra payments, and the interest you avoid by paying down the highest-rate balance first. The leverage comes from doing the math before you act, so you can see how much an extra payment shortens the term and how much interest it saves. BoringToolsKit's debt calculators model the payoff date and interest for your balances so you can pick the strategy that saves you the most.
- The avalanche method pays the highest-interest balance first.
- The snowball method pays the smallest balance first for motivation.
- Extra payments shorten the term and cut total interest.
- List every balance, its rate, and its minimum payment.
- Compare the avalanche and snowball payoff orders.
- See how an extra monthly payment changes the payoff date and interest saved.
Worked example: a $12,000 card at 22%
- Step 1: Debt Payoff Calculator — Enter $12,000 at 22% APR with a $350 monthly payment See: Paid off in about 55 months with roughly $7,000 of interest
- Step 2: Credit Card Payoff Calculator — Same balance and rate; compare a $500 payment See: A bigger payment cuts both the term and the interest sharply
- Step 3: Balance Transfer Savings Calculator — Compare transferring $12,000 to a 0% offer with a 3% fee See: The fee vs interest tradeoff shows whether the transfer wins
Numbers depend on the inputs you enter; the walkthrough shows one realistic scenario.
