Coast FIRE Calculator is a planned calculator in the finance section of Super Calculator, covering retirement.
What this calculator will compute
Inputs: current age, retirement age, current portfolio (currency), target annual spending (currency), expected real return (%) and withdrawal rate (%).
Outputs: coast number (currency), surplus or shortfall (currency) and age at which coasting becomes possible.
Formula, recorded as scope and not yet verified against a primary source: Solves the present portfolio value that, with no further contributions, compounds to the retirement target by the target date: required = target / (1 + r)^n. Reaching it means contributions can stop while the timeline holds.
