Question 1

What is the difference between the debt snowball and debt avalanche?

Accepted Answer

The debt snowball pays off your smallest balance first (regardless of interest rate), then rolls that payment into the next-smallest debt. The debt avalanche pays off your highest-interest debt first, which saves the most money mathematically. The snowball gives you faster psychological wins; the avalanche gives you lower total interest. This calculator shows both so you can compare.

Question 2

Which debt payoff method is better?

Accepted Answer

Mathematically, the avalanche always wins — it minimizes total interest paid. But personal finance is personal: many people stay motivated by the quick wins of the snowball method and are more likely to finish. If the difference in total interest is small, the snowball's motivation advantage may matter more. If it's large, the avalanche is worth the discipline.

Question 3

What is the 'extra payment' and why does it matter so much?

Accepted Answer

The extra payment is any amount you pay above the combined minimums each month. It's the single biggest lever in getting out of debt. Even a small extra amount dramatically shortens your payoff timeline because it goes entirely toward principal — and as each debt is cleared, its freed-up minimum gets added to the snowball, accelerating everything.

Question 4

What happens if my minimum payments don't cover the interest?

Accepted Answer

If your combined minimum payments are too low to cover the interest charged, your balances will grow instead of shrink, and you'll never pay the debt off. This calculator caps its projection and will flag this situation. The fix is to increase your monthly payment — even a modest extra amount can turn the math around.

Question 5

Should I pay off debt or invest first?

Accepted Answer

A common rule of thumb: pay off high-interest debt (roughly 7%+ APR, like most credit cards) before investing, because guaranteed interest savings usually beat uncertain market returns. For low-interest debt (like some student loans or mortgages), it can make sense to invest while paying the minimums. Always capture any employer 401(k) match first — that's an instant 100% return.
