Mortgage Payoff Date Calculator
Mortgage Payoff Date: a planned Super Calculator tool. Covers current balance (currency). Stub page while the tool and its worked example are prepared.
Mortgage Payoff Date Calculator is a planned calculator in the real estate section of Super Calculator, covering amortization and payoff.
What this calculator will compute
Inputs: current balance (currency), rate (%), monthly payment (currency), extra payment (currency) and next payment date.
Outputs: payoff date, remaining payments and total remaining interest (currency).
Formula, recorded as scope and not yet verified against a primary source: Solves the annuity for n: n = -ln(1 - iB/PMT) / ln(1+i), returning the number of remaining payments and hence the payoff calendar date. Undefined when PMT is at or below iB, which is the negative amortization boundary and must be trapped.
