eng.critical-path-method Calculator
Calculates critical path duration, float for each activity, and early/late start and finish times for a project network using CPM. Critical path activities have zero total float — any delay directly delays the project, making them the focus of schedule management attention.
Inputs
A Days
Length of time the process lasts. Ensure units are consistent with rate inputs.
B Days
Reference formula or conversion factor shown for context.
C Days
Reference formula or conversion factor shown for context.
D Days
Reference formula or conversion factor shown for context.
Results
project duration (critical path)
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%.
path A→B→D
The value at the specified point or condition.
path A→C→D
The value at the specified point or condition.
total float on B
The combined total across all inputs and components.
total float on C
The combined total across all inputs and components.
