Estimate to Complete (ETC).

Calculates the Estimate to Complete (ETC), which is the expected cost to finish the remaining work.

Usage

etc(bac, ev, cpi = NULL)

Arguments

bac

Budget at Completion (BAC) (total planned budget).

ev

Earned Value.

cpi

Cost Performance Index. If NULL, assumes remaining work will be completed at planned cost (ETC = BAC - EV). If provided, adjusts for current performance (ETC = (BAC - EV) / CPI).
