Estimate at Completion (EAC) Formulas

\[ EAC = AC + ETC \] \[ EAC = \frac{BAC}{CPI} \] \[ EAC = AC + (BAC – EV) \] \[ EAC = AC + \frac{(BAC – EV)}{CPI \times SPI} \]

Where:

• $$EAC$$ = Estimate at Completion (forecasted total cost)
• $$AC$$ = Actual Cost (amount spent so far)
• $$ETC$$ = Estimate to Complete (expected cost to finish remaining work)
• $$BAC$$ = Budget at Completion (original total budget)
• $$EV$$ = Earned Value (value of work actually performed)
• $$CPI$$ = Cost Performance Index (efficiency of cost usage)
• $$SPI$$ = Schedule Performance Index (efficiency of schedule usage)

The Estimate at Completion (EAC) Calculator is a critical tool for project managers to predict the final project cost based on different performance scenarios. By analyzing project spending and work performance metrics, this calculator helps identify potential overruns early and enables better budgeting and management actions.
