Education Funding Gap Calculator

Education funding arithmetic over caller-declared inputs: the future value of a declared current balance grown at a declared annual return over a declared horizon, and the funding gap against a declared goal, with a GAP_COMPUTED or GOAL_MET verdict and a full trace. On the overfunded path the page echoes a declared rollover cap in the trace note; the cap is your declaration, never a determination that any rollover is available or advisable. Absent or invalid inputs fail closed and are named. Rounding is 2dp half-up. Arithmetic only: not financial advice. No network, no storage, no clock.
