Find the slack in your schedule.
Total float tells you how long an activity can slip before it delays the whole project. Zero float means it is on the critical path.
| Type | Formula | Means |
|---|---|---|
| Total float | Late start − early start | Slip before the project finish moves |
| Free float | Successor early start − early finish | Slip before the next activity moves |
| Zero float | Total float = 0 | On the critical path |
Your activity (in day numbers)
Early and late dates come from the forward and backward pass of your schedule. Successor early start is only needed for free float.

Little slack. A short delay could reach the critical path
One activity here. Your whole critical path in POD.
This finds the float on one activity. POD reads the schedule files your team already exports and surfaces total float and the critical path across the whole job, updated as real dates come in.
We won't invent numbers you didn't give us.
See the critical path on your own schedule.
POD turns the schedules you already export into live float and critical-path views. As complete as your data.
