How do you calculate Estimate at Completion (EAC)?

One common formula is EAC = BAC ÷ CPI, assuming future cost performance matches current CPI.

Why is EAC important?

EAC forecasts total cost at completion so you can understand if you're trending over or under the original budget.

Use this EAC Calculator to forecast your total projected cost at completion using standard earned value management (EVM) metrics.

BAC (Budget at Completion) $ CPI (Cost Performance Index)

A common EAC formula is: EAC = BAC ÷ CPI. This assumes current cost performance (CPI) continues through the rest of the project.

EAC helps sponsors see how far off the original budget you’re trending as work progresses.
