Variables:

- SPI is the Schedule Performance Index ((EV/PV))
- EV is the earned value
- PV is the planned progress

To calculate Schedule Performance Index, divide the earned value by the planned progress.

## How to Calculate Schedule Performance Index?

The following steps outline how to calculate the Schedule Performance Index.

- First, determine the earned value.
- Next, determine the planned progress.
- Next, gather the formula from above = SPI = EV / PV.
- Finally, calculate the Schedule Performance Index.
- After inserting the variables and calculating the result, check your answer with the calculator above.
