FormulaCost per day cut = (v.crash_cost-v.normal_cost)/(v.normal_days-v.crash_days) ; Net saving = v.days_to_cut*(v.indirect_daily-(v.crash_cost-v.normal_cost)/(v.normal_days-v.crash_days))

Worked example

Inputs

Normal days
10 days
Crash days
6 days
Normal cost
10000 currency
Crash cost
16000 currency
Days to cut
3 days
Indirect daily
2000 currency/day

Expected results

Cost per day cut
1500 currency/day
Net saving
1500 currency

How to use this tool

  1. Enter your own assumptions using a consistent currency and period.
  2. Review the scenario outputs and compare alternative inputs.
  3. Check the stated model limits before using the result in an operating plan.

Try this example

{
  "normal_days": 10,
  "crash_days": 6,
  "normal_cost": 10000,
  "crash_cost": 16000,
  "days_to_cut": 3,
  "indirect_daily": 2000
}

Accuracy and scope

Assumes this task stays on the sole critical path and cost slope is linear. Does not recompute a network or parallel critical paths.
