fin.critical-path-float Calculator
Calculates earliest finish, latest start, total float, and the critical path for a project network from task durations and dependencies. Tasks on the critical path have zero float — any delay to a critical task directly delays the project completion date.
Inputs
Task Duration
Length of time the process lasts. Ensure units are consistent with rate inputs.
Es Early Start
Reference formula or conversion factor shown for context.
Lf Late Finish
Reference formula or conversion factor shown for context.
Results
early finish EF (day)
Sample size or count used in the calculation.
late start LS (day)
The value at the specified point or condition.
total float TF (days)
The combined total across all inputs and components.
on critical path?
The value at the specified point or condition.
EF = ES + duration
Weighted average time to receive the bond's cash flows (years). Also a price sensitivity measure: duration of 7 means a 1% rise in yields drops the bond price ~7%.
TF = LF - ES - duration = LS - ES = LF - EF
Weighted average time to receive the bond's cash flows (years). Also a price sensitivity measure: duration of 7 means a 1% rise in yields drops the bond price ~7%.
