Schedule Variance Calculator

Schedule Variance Calculator

A core Earned Value Management (EVM) metric - this calculator tells you whether a project is ahead of or behind its planned schedule.

Schedule Variance (SV) = Earned Value(EV) - Planned Value(PV)

Example

$80,000 in earned value against $100,000 in planned value:

SV = 80,000 - 100,000 = -$20,000.00 (Behind Schedule)

Reading the Result

A positive SV means more work has been completed than was scheduled at this point in the project (ahead of schedule), while a negative SV means less work has been completed than planned (behind schedule) - a value of exactly zero means the project is precisely on schedule.

Why SV Is Measured in Dollars, Not Days

Unlike a simple calendar-day delay, Schedule Variance expresses schedule performance in dollar terms of value delivered - this lets it be combined meaningfully with cost metrics like CPI within the same Earned Value Management framework.
