PK0-005 Tools and Documentation Practice Question
A project is 60% complete. The original budget (BAC) is $200,000. Actual costs to date are $130,000, and the earned value is $120,000. What is the estimate at completion (EAC) if the project will continue to perform at the current cost efficiency?
⚠ Common exam trap
The trap is mixing up EAC formulas; candidates often apply EAC = AC + (BAC - EV) or simply add the variance to BAC, producing $210,000 or $230,000 instead of dividing BAC by CPI.

Correct answer & explanation
✓
$216,667
EAC is calculated using the formula EAC = BAC / CPI when the project is expected to continue at the current cost efficiency. Here CPI = EV / AC = 120,000 / 130,000 = 0.9231, so EAC = 200,000 / 0.9231 = $216,667. This matches option A and reflects the cost overrun trend observed to date.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
$216,667
Why this is correct
Dividing budget at completion by cost performance index ($200,000 ÷ ($120,000 ÷ $130,000)) yields $216,667. This satisfies the stem's constraint that the project continues at its current cost efficiency, so EAC is BAC ÷ CPI rather than a bottom-up re-estimate.
- ✗
$250,000
Why it's wrong here
This divides BAC by the earned-value percentage rather than by CPI, conflating schedule progress with cost performance. The current cost efficiency is $120,000 ÷ $130,000, giving roughly $216,667. Percentage-of-completion arithmetic belongs to independent EAC estimates, not the continuing-CPI formula the scenario specifies.
- ✗
$200,000
Why it's wrong here
Assuming the original budget equals the final cost ignores the $10,000 overspend already incurred: CPI is $120,000 ÷ $130,000, so the project is spending faster than it earns. BAC-based EAC applies only when remaining work is expected to proceed at planned cost efficiency, which the stem explicitly rules out.
- ✗
$230,000
Why it's wrong here
This applies the TCPI-style remaining-budget arithmetic, but EAC at current cost efficiency is BAC divided by CPI ($200,000 ÷ 0.923), giving roughly $216,667. The figure here instead adds the cost variance to BAC, which suits a one-off variance that will not recur, not the continuing-efficiency assumption stated.
