Practical Example
Formula: months = −log(1 − D × r / M) / log(1 + r), where D = debt, r = monthly rate, M = monthly payment. Total interest = M × months − D.
Frequently Asked Questions
How long will it take to pay off my debt?
It depends on your balance, interest rate, and monthly payment — higher payments dramatically shorten the payoff period.
Should I pay off the highest-rate debt first?
Generally yes — the avalanche method (highest APR first) saves the most interest, while the snowball method (smallest balance first) builds momentum.
Does this account for fees or extra charges?
No — this estimate uses balance, rate, and payment only; late fees and balance-transfer fees can change the timeline.
How do interest rates affect my monthly payment?
Interest rates have a major impact on monthly payments. Even a 0.5% difference in APR can change your payment by $50-$200 per month on a typical loan. Use this calculator to compare different rate scenarios side by side.
Should I choose a fixed or variable rate?
Fixed rates give you predictable payments for the life of the loan, while variable rates start lower but can rise over time. Fixed is usually safer for long-term loans (mortgages, auto); variable can make sense for short-term borrowing when you expect rates to fall.
