That gives us a cost performance index of 362,250 / 430,000 = 0.84, so the correct answer should be D) 0.84.

I agree with In. The formula for cost performance index is EV/AC.

So, if we plug in the numbers, EV is $805,000 x 45% = $362,250, and AC is $430,000.

I think the cost performance index should be calculated as the ratio of earned value to actual cost.

I think it will be 0.84 based on how much of the budget we've actually used.

Alright, let's do this! Budgeted Cost of Work Performed = 45% of $805,000 = $362,250. Actual Cost of Work Performed = $430,000. CPI = $362,250 / $430,000 = 0.84.

CPI = Budgeted Cost of Work Performed / Actual Cost of Work Performed. So we need to calculate those values first.

Hold on, how did you arrive at that? I'm still trying to wrap my head around the formula for CPI.

We know the earned value is $805,000 * 0.45 which is $362,250.

So for this project, we need to use the formula CIP = EV / AC.

To calculate CPI, you divide the earned value by the actual cost.

I'm leaning towards option C, 0.86. That seems to make the most sense based on the information provided.

Okay, let's think this through step-by-step. We've got the budget, the percentage of work completed, and the actual amount spent. Shouldn't be too hard to figure out the cost performance index.
