What This Calculator Does

Simulate payment shock when an ARM resets to a higher rate.

It combines Remaining Balance, Years Remaining, Current ARM Rate, Reset Rate to estimate Payment Shock, Current Payment, Reset Payment.

Formula & Method

Core equations: Payment shock when ARM resets: \Delta M = M_{reset} - M_{current} \text{Shock \%} = \frac{\Delta M}{M_{current}} \times 100 Inputs are applied in base units, then derived metrics are computed from the same equations and rounded for display.

Notation used in the formulas: R = Payment Shock; x_{1} = Remaining Balance; x_{2} = Years Remaining; x_{3} = Current ARM Rate; x_{4} = Reset Rate.

Method summary: inputs are normalized to consistent units, core equations are evaluated, then secondary values are derived and rounded for display.

Use this calculator for quick scenario analysis. Start with baseline values, change one driver at a time, and compare how sensitive the results are to each input shown above.

Inputs Used

  • Remaining Balance: Used directly in the calculation.
  • Years Remaining: Used directly in the calculation.
  • Current ARM Rate: Used directly in the calculation.
  • Reset Rate: Used directly in the calculation.
