1. What is the Debt Payoff Calculator?

The Debt Payoff Calculator estimates how many months it will take to pay off a debt based on your current balance, interest rate, and monthly payment amount. This helps in financial planning and debt management.

2. How Does the Calculator Work?

The calculator uses the debt payoff equation:

\[ Months = \frac{\log(1 + (Balance \times r / PMT))}{\log(1 + r)} \]

Where:

\( Balance \) — Current debt amount (USD)
\( r \) — Monthly interest rate (decimal)
\( PMT \) — Monthly payment amount (USD)

Explanation: The equation calculates the time required to pay off debt by considering the compounding effect of interest on your payments.

3. Importance of Debt Payoff Calculation

Details: Knowing your payoff timeline helps with budgeting, comparing repayment strategies, and understanding the true cost of debt.

4. Using the Calculator

Tips: Enter your current debt balance in USD, monthly interest rate as a decimal (e.g., 0.05 for 5%), and your fixed monthly payment amount. All values must be positive.

5. Frequently Asked Questions (FAQ)

Q1: Why does the result sometimes show as invalid?
A: This happens when your monthly payment doesn't cover the interest (payment ≤ balance × rate), meaning you'll never pay off the debt.

Q2: How accurate is this calculator?
A: It assumes fixed payments and interest rates. Actual results may vary if these change.

Q3: Should I include fees in the payment amount?
A: Yes, include all amounts that reduce your principal when calculating payoff time.

Q4: What's the difference between APR and monthly rate?
A: Monthly rate = APR/12. This calculator needs the monthly rate as a decimal.

Q5: How can I pay off debt faster?
A: Increase monthly payments, make biweekly payments, or reduce interest rates through refinancing.
