Estimate To Complete Calculator

Work out estimate to complete instantly with clear inputs, formula shown and shareable results.

About Estimate To Complete Calculator

Estimate to complete is the forecast cost of the work remaining, and the method matters enormously. Assuming performance continues at the current CPI is the pessimistic and usually more accurate approach; assuming recovery to the budgeted rate requires a credible reason for the improvement.

Formulas

ETC at current CPI

ETC = (Budget at completion - Earned value) / CPI

ETC at budgeted rate

ETC = Budget at completion - Earned value

Estimate at completion

EAC = Actual cost + ETC

Worked example

With the default values below, Estimate To Complete Calculator returns Estimate to complete of $15,466,666.67. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits

The result is derived only from the 4 inputs listed above. Anything not among them is not part of the calculation.
In particular, this calculator does not take inflation, tax or compounding frequency into account.
Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

Which method should I report?

Report both and state the assumption. Reporting only the recovery case without justifying it is how cost overruns get discovered late.

Is variance at completion the overrun?

Yes — a negative variance at completion is the forecast overrun against the approved budget.
