🧮 Float Calculator

Compute total float (LS − ES or LF − EF) and free float from activity dates to know how much an activity can slip.

Early Start (ES) (day number)

Early Finish (EF) (day number)

Late Start (LS) (day number)

Late Finish (LF) (day number)

Successor Early Start (optional, for free float)

Formulas: Total Float = LS − ES = LF − EF. Free Float = ES(successor) − EF. Enter day numbers from your CPM forward/backward pass.
