Debt Payoff Calculator
Calculate how long it will take to pay off your debt and how much interest you'll pay over time.
Who This Is For
If you have a single loan, credit card, or other debt and want to know exactly when it will be paid off, this calculator is for you. Whether you're just starting to tackle debt or exploring how extra payments could help, this tool gives you a clear timeline.
Example Scenario
Say you owe $5,000 on a credit card at 18% APR and pay $200/month. This calculator shows you'll be debt-free in about 32 months, paying roughly $1,314 in interest.
Adding just $50/month extra cuts the timeline to about 25 months and saves you around $350 in interest.
Use this calculator to find out exactly how long it will take to pay off your debt and how much interest you'll pay. Simply enter your current balance, interest rate, and monthly payment amount to see your complete payoff timeline.
The calculator shows you the total interest you'll pay, your payoff date, and a detailed month-by-month payment schedule. You can also add extra payments to see how much faster you could become debt-free and how much interest you could save.

A 18% Interest Rate Is Silently Draining You
At 18% APR, nearly half your payment goes to interest instead of reducing your balance. Understanding how interest compounds is the first step to fighting back.
🎉 Now That You're Debt-Free...
Don't let lifestyle inflation eat your progress. Redirect that payment toward building wealth and securing your future.

Your 18% Rate Is Costing You Thousands
That interest rate is eating your progress. Refinancing to a lower rate could save you significant money and cut months off your timeline.
How It Works
This calculator uses month-by-month simulation to determine your debt payoff timeline. Each month, interest is calculated on your remaining balance, then your payment is applied.
The calculator assumes:
- Fixed monthly payments
- Consistent APR throughout the loan
- No additional charges or fees
- Payments made on time each month
Assumptions and Formula
Assumptions used in this model:
- Fixed APR across the entire payoff period.
- Fixed monthly payment and optional fixed extra payment.
- Monthly compounding with payments applied each cycle.
Core monthly update: new balance = prior balance + monthly interest - payment, where monthly interest = balance × (APR / 12).
How to Interpret Your Results
| Signal | What It Means | Action |
|---|---|---|
| Payment barely exceeds interest | Principal is shrinking slowly | Increase payment by 10-20% |
| Large interest share of total paid | Rate is dominating the plan | Model refinance scenarios |
| Small extra payment cuts many months | You are near a payoff acceleration threshold | Automate that extra payment monthly |
