Estimate at Completion (EAC) Calculator
Forecast total project cost with all four PMI EAC formulas side-by-side and pick the one that fits your assumption.
Project Inputs
All values in the same currency unit (e.g. USD thousands).
Total approved project budget.
Total cost incurred to date.
Budgeted value of work completed. EV = BAC × % done.
Budgeted cost of work scheduled through today.
Your bottom-up estimate to finish remaining work. Required for Formula 2.
Key Metrics
EAC Forecasts
Assumes future work continues at the current cost efficiency. The most common PMI formula.
Uses your bottom-up re-estimate for remaining work. Most accurate when ETC is reliable.
Optimistic: treats the overrun as a one-time event; remaining work will be on budget.
Pessimistic: accounts for both cost and schedule inefficiency driving future overruns.

Summary
Forecast total project cost with all four PMI EAC formulas side-by-side and pick the one that fits your assumption.
How it works
- Enter BAC — the total approved budget for the project.
- Enter AC — actual cost spent on the project to date.
- Enter EV — the budgeted value of work actually completed (BAC × % done).
- Enter PV — the budgeted cost of all work scheduled to be done by now.
- Optionally enter ETC — your bottom-up estimate to finish remaining work.
- Four EAC formulas calculate instantly with the recommended formula highlighted.
Use cases
- Forecast final project cost for a monthly PMO status report.
- Compare optimistic vs. pessimistic cost-at-completion scenarios.
- Justify a revised budget request to a project sponsor.
- Practice EAC formulas for the PMP or CAPM exam.
- Determine whether the project can still finish within the approved budget.
- Cross-check a vendor's cost-to-complete estimate against CPI-based forecasts.
