What is Debt Payoff?

Debt payoff is the process of eliminating your outstanding debt by making regular payments until the balance reaches zero. A Debt Payoff Calculator estimates how many months or years it will take to pay off your debt based on your current balance, interest rate, and monthly payment. It also allows you to explore how making extra payments can shorten your repayment period and reduce the total interest paid.

  • Debt Balance: The current amount you owe.
  • Monthly Payment: The fixed amount you commit to paying each month.
  • Interest Rate: The annual rate at which your debt accrues interest, converted to a monthly rate for calculations.

Calculation Formulas

To estimate the payoff time for your debt, we use a common formula for fixed-rate loans:

$$ n = \frac{\ln\left(\frac{M}{M – r \times B}\right)}{\ln(1+r)} $$

Where:

  • \( n \) is the number of months required to pay off the debt.
  • \( M \) is your monthly payment (including any extra payment).
  • \( B \) is the current debt balance.
  • \( r \) is the monthly interest rate (annual rate divided by 12).

Additionally, the total interest paid over the life of the debt can be calculated by:

$$ \text{Total Interest} = (M \times n) – B $$

Key Concepts

  • Monthly Payment (M): The amount you plan to pay each month towards your debt.
  • Debt Balance (B): The current outstanding debt amount.
  • Interest Rate (r): The annual interest rate, which is converted to a monthly rate for these calculations.
  • Payoff Time (n): The number of months required to completely pay off your debt.
  • Extra Payments: Additional payments made to reduce the principal faster, thereby lowering the overall interest and shortening the payoff period.

Step-by-Step Process

  1. Input Your Debt Details:

    Enter your current debt balance (\(B\)), annual interest rate, and your desired monthly payment (\(M\)). Include any extra payment amount if you plan to make additional contributions.

  2. Convert Annual Interest Rate to Monthly Rate:

    Calculate the monthly interest rate:

    $$ r = \frac{\text{Annual Interest Rate}}{12} $$

  3. Apply the Payoff Formula:

    Substitute your values into the payoff formula:

    $$ n = \frac{\ln\left(\frac{M}{M – r \times B}\right)}{\ln(1+r)} $$

  4. Calculate Total Interest (Optional):

    Compute the total interest paid using:

    $$ \text{Total Interest} = (M \times n) – B $$

  5. Review the Results:

    The calculator displays the estimated number of months to pay off your debt, along with the total interest (if calculated). Compare different monthly payment scenarios to see how extra payments affect your payoff timeline.

Practical Examples

Example: Paying Off a \$10,000 Debt

Scenario: Suppose you have a debt balance of \$10,000 with an annual interest rate of 12% and you plan to pay \$300 per month.

  1. Convert the Interest Rate:

    $$ r = \frac{0.12}{12} = 0.01 $$

  2. Apply the Payoff Formula:

    $$ n = \frac{\ln\left(\frac{300}{300 – 0.01 \times 10000}\right)}{\ln(1+0.01)} $$

    Since \(0.01 \times 10000 = 100\), the formula simplifies to:

    $$ n = \frac{\ln\left(\frac{300}{200}\right)}{\ln(1.01)} $$

    This gives an approximate payoff time of around 42 months.

  3. Calculate Total Interest:

    $$ \text{Total Interest} = (300 \times 42) – 10000 \approx \$260 $$

  4. Interpretation:

    With a monthly payment of \$300, it will take roughly 42 months (3.5 years) to pay off your \$10,000 debt, with total interest of approximately \$260. Increasing your monthly payment will shorten this timeline.
