Becoming debt-free starts with a clear plan. This calculator works backwards from your goal—tell it when you want to be debt-free, and it calculates exactly how much you need to pay each month to get there.
How This Calculator Works
This calculator creates your debt freedom roadmap:
- Current Balance: Total debt you want to eliminate
- Interest Rate: Your APR (Annual Percentage Rate)
- Target Payoff Date: When you want to be debt-free
- Monthly Payment: What you need to pay to hit your goal
- Total Interest: How much extra you'll pay beyond principal
The Formula Explained
Monthly Payment = P × [r(1+r)^n] / [(1+r)^n - 1]
Where:
- P = Principal (current balance)
- r = Monthly interest rate (APR ÷ 12)
- n = Number of months until payoff date
This formula solves for the fixed monthly payment needed to reach $0.

Frequently Asked Questions
How is debt payoff different from amortization?
Amortization shows how a loan is structured to be paid off over its full term. Debt payoff calculators help you pay faster than required. Minimum payments maximize lender profits; this calculator shows how extra payments dramatically reduce interest and payoff time.
Should I use the avalanche or snowball method?
Avalanche (highest interest first) saves the most money mathematically. Snowball (smallest balance first) provides psychological wins that keep you motivated. Studies show snowball often works better in practice because people stay committed. Choose what fits your personality.
Extra payments have massive impact. Example: $20,000 at 18% APR with $400/month minimum takes 9 years and costs $22,000 in interest. Adding just $200/month cuts it to 4 years and $7,500 interest—saving $14,500 and 5 years of payments!
Should I pay off debt or save/invest?
Generally, pay off high-interest debt first (anything above 7-8%). Keep a small emergency fund ($1,000-$2,000) to avoid new debt for surprises. Once high-interest debt is cleared, build emergency fund to 3-6 months, then invest. Never sacrifice employer 401(k) match—that's instant 50-100% return.
How do I stay motivated during debt payoff?
Strategies: (1) Track progress visually with a debt payoff chart, (2) Celebrate milestones (first $1,000 paid, each card eliminated), (3) Calculate how much interest you're saving, (4) Set a specific debt-free date and countdown, (5) Join debt payoff communities for accountability.
What if I can't afford the payments this calculator shows?
If the required payment exceeds your budget: (1) Extend your timeline to lower the monthly amount, (2) Look for expenses to cut temporarily, (3) Increase income with side work, (4) Consider balance transfers or debt consolidation for lower rates, (5) In extreme cases, consult a nonprofit credit counselor.
Should I close credit cards as I pay them off?
Not necessarily. Closing cards can hurt your credit score by reducing available credit and shortening credit history. Instead, keep zero-balance cards open (use occasionally for small purchases and pay immediately). Only close cards with annual fees you can't justify.
What's the impact of just paying minimums?
Minimum payments are designed to maximize lender profits. On a $10,000 credit card at 18% with 2% minimum: payoff takes 30+ years, and you pay $18,000+ in interest—nearly triple the original debt! Even $50-100 extra monthly makes an enormous difference.
Key Points to Remember
- Set a date: Vague goals rarely succeed—pick a specific debt-free day
- Pay more than minimums: Even small extra amounts save thousands
- Stop adding debt: Freeze cards or cut them up during payoff
- Attack highest rates first: Unless you need snowball motivation
- Celebrate wins: Every payment is progress—track and appreciate it
