Examples

bac <- 100000
eac <- 120482 # From EAC calculation

vac <- vac(bac, eac)
cat("Variance at Completion (VAC):", round(vac, 2), "\n")
#> Variance at Completion (VAC): -20482 
cat("Project is expected to be", abs(round(vac, 2)), ifelse(vac < 0, "over", "under"), "budget\n")
#> Project is expected to be 20482 over budget
