Building and upgrade ROI

Is this build or upgrade worth the money?

The investment

The additional profit per hour, not the total. Subtract what this capital already earns elsewhere so you are comparing the true improvement.

Counted against the return: capital spent is earning nothing while construction runs.

The period the return is measured over.

Steps

  1. Payback period2,000hours
    cost / incrementalProfitPerHour
  2. Net over horizon$-64,000$
    incrementalProfitPerHour x (horizonHours - leadTimeHours) - cost
  3. ROI over horizon$-0.640
