10,000 credit card debt at 22% with 200 minimum monthly takes 94 months (7.8 years) and costs 8,800 in interest. Adding 100 extra cuts it to 52 months (3.9 years) and 3,300 interest. 100/month extra saves 5,500 and 4 years. Motivation is the hardest part — seeing the numbers can help.
Run it with sensible defaults
Using debt balance of 10,000, annual rate of 22%, minimum monthly of 200, extra monthly of 100, the calculation works out to 52 months. Nudge the inputs toward your own situation and the output recalculates instantly. The defaults are meant as a starting point, not a recommendation.
The levers in this calculation
The inputs — Debt Balance, Annual Rate, Minimum Monthly, and Extra Monthly — do not pull with equal force. Not every input has equal weight. Flip one at a time toward extreme values to feel which ones move the needle most for your situation.
How the math works
Month-by-month simulation. Interest added each month, then payment deducted. Stop when balance clears. The working is transparent — you can verify every step yourself in the formula section below. No black box, no opaque "proprietary model".
Reading the output honestly
The payoff date assumes every payment lands on time and at the amount you entered. In reality, months with unexpected expenses happen. Treat the figure as the best-case timeline and add a buffer for life if you want a realistic target.
What this doesn't capture
Real payoff journeys include missed payments, fee changes, balance transfers, and promotional rates that reset. The calculation assumes a steady plan; reality is rarely that clean. Use the figure as the best-case plan against which actual progress gets measured.
Debt payoff months produce a timeline based on the inputs provided.
