15-Year Versus 30-Year Mortgage Comparison: a planned Super Calculator tool. Stub page: the tool, its formula and a worked example are not published yet.
15-Year Versus 30-Year Mortgage Comparison is a planned calculator in the real estate section of Super Calculator, covering amortization and payoff.
What this calculator will compute
Inputs: loan amount (currency), 15-year rate (%), 30-year rate (%), investment return (%) and marginal tax rate (%).
Outputs: payment per term (currency), total interest per term (currency), break-even investment return (%) and terminal wealth per path (currency).
Formula, recorded as scope and not yet verified against a primary source: Compares two annuities at their respective rates, where the shorter term prices below the longer one, against the alternative of taking the 30-year term and investing the payment difference at an assumed return. Break-even return = the rate at which investing the difference matches the interest saved.
