Budget at Completion Calculator

Build a BAC from project budget components, then continue directly into a complete earned value analysis.

BAC Builder

Add the performance-budget components that make up the project baseline. Keep management reserve separate.

What is Budget at Completion?

BAC is the total budget for the work included in the performance measurement baseline at project completion. In a well-controlled EVM system, it is not simply “all available money.” Management reserve is maintained separately from the performance measurement baseline.

BAC = total authorized performance budget at completion

How to calculate BAC

If your project is being built from cost packages or major budget categories, sum the authorized baseline budget for all scoped work. The builder above is a convenience for that arithmetic; in an operating EVMS, BAC should reconcile to the approved baseline.

BAC vs project funding

Project funding, contract budget base and BAC can differ depending on governance and reserve treatment. That distinction matters when you later calculate VAC or TCPI, because those metrics use BAC as the performance target.

What BAC connects to

BAC becomes an input to EAC, VAC and TCPI. If you already have BAC, the full EVM calculator is the fastest route to all metrics.
