Question 1

How long does it take to pay off $10,000 in credit card debt?

Accepted Answer

At a typical credit card rate of 20% APR with $250/month payments, it takes about 62 months (just over 5 years) and costs roughly $5,400 in interest. Increasing payments to $400/month cuts the timeline to 32 months and saves about $2,700 in interest. Even a small increase in monthly payments makes a significant difference because more of each payment goes toward the principal.

Question 2

Should I use the debt avalanche or snowball method?

Accepted Answer

The avalanche method (paying highest-interest debt first) saves the most money mathematically. The snowball method (paying smallest balances first) provides quicker psychological wins. Research from Harvard Business Review shows people using the snowball method are more likely to stick with their plan. Choose avalanche if you are disciplined about numbers; choose snowball if motivation is your challenge.

Question 3

What happens if I only make minimum payments?

Accepted Answer

Minimum payments are designed to keep you in debt longer. On a $10,000 credit card balance at 20% APR, the minimum payment (typically 2% of balance or $25, whichever is higher) would take over 30 years to pay off and cost more than $19,000 in interest — nearly double the original debt. Always pay more than the minimum if possible.

Question 4

Is debt consolidation a good idea?

Accepted Answer

Consolidation makes sense when you can get a significantly lower interest rate than your current debts. For example, replacing 20% credit card debt with an 8% personal loan saves substantial interest and simplifies payments. However, consolidation does not reduce the principal — it only restructures it. Avoid consolidation if: (1) the new rate is not meaningfully lower, (2) you will run up the original cards again, or (3) the new loan has high origination fees.

Question 5

How do extra payments affect my debt payoff?

Accepted Answer

Extra payments go directly to reducing principal, which means less interest accrues the following month. Even $50 extra per month on a $20,000 loan at 10% can save thousands in interest and years off the timeline. The impact is greatest early in the repayment period when the balance is highest. Use the scenario comparison feature to see exactly how much different payment amounts save.

Question 6

Should I pay off debt or invest?

Accepted Answer

Compare the guaranteed return of debt payoff (your interest rate) against expected investment returns. If your debt charges 18%, paying it off is equivalent to earning an 18% guaranteed return — better than any typical investment. But if your debt is at 4% and you expect 8% investment returns, investing may win mathematically. Always maintain an emergency fund regardless, and take advantage of any employer 401(k) match (free money) even while paying off debt.

Question 7

What if my payment does not cover the monthly interest?

Accepted Answer

If your monthly payment is less than the interest charged that month, your balance actually grows — this is called negative amortization. For example, on $10,000 at 18% APR, monthly interest is $150. If you pay only $100, $50 is added to your balance each month. The calculator warns you when this happens. You must increase your payment above the monthly interest amount to make any progress.
