PK0-005 Practice Question: At a certain point in the project, the earned…
At a certain point in the project, the earned value (EV) is $500, the planned value (PV) is $600, and the actual cost (AC) is $400. What is the schedule performance index (SPI)?
⚠ Common exam trap
CompTIA often tests the distinction between SPI (EV/PV) and CPI (EV/AC), and the trap here is that candidates mistakenly use AC in the denominator for SPI, leading to the incorrect 1.25 answer (Option B).

Correct answer & explanation
✓
0.83
The Schedule Performance Index (SPI) is calculated as EV / PV. With EV = $500 and PV = $600, SPI = 500 / 600 = 0.8333, which rounds to 0.83. An SPI less than 1.0 indicates the project is behind schedule because less value has been earned than planned.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
0.83
Why this is correct
Correct calculation: EV/PV = 500/600 = 0.83.
- ✗
1.25
Why it's wrong here
1.25 would result from dividing PV by AC or similar miscalculation.
- ✗
0.67
Why it's wrong here
0.67 would result from dividing PV by EV or similar miscalculation.
- ✗
1.20
Why it's wrong here
1.20 would result from dividing AC by EV or similar miscalculation.
