Formula
Months to Payoff = -log(1 - (Debt × Monthly Rate) / Payment) / log(1 + Monthly Rate)
Total Interest = (Monthly Payment × Months) - Debt
Example Calculation:
If debt $10,000, rate 18% (1.5% monthly), payment $300/month:
• Monthly interest = $10,000 × 1.5% = $150
• Principal paid = $300 - $150 = $150
• Months to payoff: ~42 months
• Total interest: ~$2,600

Frequently Asked Questions
How long will it take to pay off my debt?
Payoff time depends on your debt amount, interest rate, and monthly payment. Higher payments significantly reduce payoff time. Use this calculator to see your specific timeline based on your payment amount.
How much interest will I pay?
Total interest depends on debt amount, interest rate, and how long you take to pay off. The calculator shows your exact total interest based on your monthly payment. Higher payments reduce total interest.
Should I pay more than the minimum?
Yes! Paying more than the minimum significantly reduces payoff time and total interest. Even small increases can save hundreds or thousands in interest and reduce payoff time by months or years.
What if my payment is too low?
If your monthly payment is less than or equal to the monthly interest, you won't be able to pay off the debt - the balance will grow. You must pay more than the monthly interest to make progress on paying off debt.
