How It Works
Enter your debt 1 balance, debt 1 apr (%), debt 1 min payment, debt 2 balance, debt 2 apr (%), debt 2 min payment, extra monthly payment, and the calculator instantly computes your payoff duration, total interest, years to pay off. For example, with Debt 1 Balance: $3,000, Debt 1 APR (%): 18%, Debt 1 Min Payment: $75, Debt 2 Balance: $8,000, Debt 2 APR (%): 22%, Debt 2 Min Payment: $200, Extra Monthly Payment: $100, the payoff duration comes out to 42 months.

Practical Tips
- →Shop multiple lenders — even a small rate difference saves real money over the loan term
- →Always compare the APR, not just the headline interest rate
- →Extra payments toward principal shorten your payoff time and cut total interest
- →Avoid extending loan terms just to lower the monthly payment — it usually costs more overall
