Credit Card Payoff Formula and Instructions

Method 1: Monthly Interest

  • Monthly interest rate = Annual Rate / 12 / 100.
  • Interest Paid = Starting Balance x monthly interest rate.

Method 2: Principal Reduction

  • Principal Paid = Payment - Interest Paid.
  • Ending Balance = Starting Balance - Principal Paid.

Method 3: Payoff and Savings

  • Simulation runs month by month until balance reaches zero.
  • Savings projection compares base plan with an extra monthly payment scenario.
