Rate Lock and Float-Down Calculator
Rate Lock and Float-Down: a planned Super Calculator tool. Covers loan amount (currency). Stub page while the tool and its worked example are prepared.
Rate Lock and Float-Down Calculator is a planned calculator in the real estate section of Super Calculator, covering mortgage core.
What this calculator will compute
Inputs: loan amount (currency), locked rate (%), lock period (days), lock or float-down fee (currency), assumed rate move (bps) and term (years).
Outputs: break-even rate move (bps), cost of the lock (currency) and payment under each scenario (currency).
Formula, recorded as scope and not yet verified against a primary source: Values an extended lock or a float-down option as the cost of the lock fee against the payment difference under an assumed rate path, and expresses the break-even as the rate move that repays the fee over the holding period. Structurally an option premium problem, not an amortization problem.
