How to use the debt payoff calculator

  1. List every debt: credit cards, personal loans, car loan, money owed to family. For each, enter what you still owe, the yearly interest rate and the minimum monthly payment.
  2. Enter the total you can pay each month across all debts. It must be at least the sum of the minimum payments; anything above that is your "extra".
  3. Pick a method and compare: the table shows how long each one takes and how much interest it costs.

Avalanche or snowball: which is better?

With the avalanche method, the extra money goes to the debt with the highest interest rate. Mathematically this always costs the least interest. With the snowball method, the extra goes to the smallest balance, so you close whole debts sooner. Many people find those quick wins help them stay on track.

If the difference in the comparison table is small, choose the one you will actually stick to. If the avalanche saves a lot, it is worth the patience.

Example: a credit card of 4,000 at 24% (minimum 100), a personal loan of 6,000 at 10% (minimum 180) and a store card of 900 at 15% (minimum 40). Total paid each month: 450.

Avalanche (credit card first): debt-free in 29 months, about 2,055 in interest. Snowball (store card first, gone in month 6): 30 months, about 2,152 in interest. The snowball costs about 100 more but gives a quick first win.

Tips to get out of debt faster

  • Stop adding new debt while you pay off the old one. Put the cards away.
  • Find extra money each month: cancel a subscription, sell something you do not use, or put any bonus or tax refund straight on the debt.
  • Ask for a lower rate. A phone call to your card provider, or moving the balance to a cheaper loan, can save a lot.
  • Track your spending so you know where the extra can come from. A simple cashbook like TallyKnot Local shows it in a few days.

Frequently asked questions

What is the debt avalanche method?

You pay the minimum on every debt and put every extra amount on the debt with the highest interest rate first. When it is paid off, you move to the next highest rate. It saves the most interest.

What is the debt snowball method?

You pay the minimum on every debt and put every extra amount on the smallest balance first. Small debts disappear quickly, which keeps many people motivated, even if it costs a little more interest.

What happens when one debt is paid off?

Its minimum payment stays in your monthly budget and moves on to the next debt in your plan. That is why the payoff speeds up over time.

Why does it not show a plan?

Either the monthly total is lower than the minimum payments, or it is so close to the monthly interest that the debt hardly goes down (more than 50 years). Increase the monthly amount, or look for a lower interest rate.

Should I use savings to pay off debt?

Keep a small emergency fund first, so an unexpected cost does not go on a credit card again. After that, paying off high-interest debt is usually one of the best returns you can get.
