Formula:

The calculator first determines your original monthly payment (M) using the amortization formula:

M = P * [i * (1 + i)n] / [(1 + i)n - 1]

Then, it calculates the remaining loan balance (Bk) after 'k' payments:

Bk = M * [ (1 - (1 + i)-(n - k)) / i ]

  • P = Original Loan Amount (Principal)
  • i = Monthly Interest Rate (Annual Rate / 1200)
  • n = Original Total Number of Payments (Loan Term in Years * 12)
  • k = Number of Payments Already Made
  • M = Calculated Monthly Payment Amount
  • Bk = Remaining Loan Balance
