PK0-005 Tools and Documentation Practice Question
A project has a budget at completion (BAC) of $200,000. After five months, the earned value (EV) is $90,000 and the actual cost (AC) is $100,000. The project manager needs to calculate the estimate at completion (EAC) assuming current cost performance will continue. What is the EAC?
⚠ Common exam trap
It's easy for candidates to confuse the EAC formulas, selecting the one for future work at budgeted rate (EAC = AC + (BAC - EV)) instead of the CPI-based formula, or they incorrectly calculate the CPI by swapping EV and AC.

Correct answer & explanation
✓
$222,222
The Estimate at Completion (EAC) when current cost performance is expected to continue is calculated using the formula EAC = BAC / CPI. First, calculate the Cost Performance Index (CPI) = EV / AC = $90,000 / $100,000 = 0.9. Then, EAC = $200,000 / 0.9 = $222,222.22, which rounds to $222,222.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
$190,000
Why it's wrong here
This would be correct if EV = AC, but CPI is 0.9.
- ✗
$210,000
Why it's wrong here
This does not match the formula.
- ✗
$200,000
Why it's wrong here
This is the BAC, not adjusted for performance.
- ✓
$222,222
Why this is correct
EAC = BAC/CPI = $200,000 / 0.9 = $222,222.22 ≈ $222,222.
