Automation Payback Calculator

Work out how many years a robot project takes to repay its investment from annual savings after ownership cost. The page shows five-year net value and return, and checks the result against a target payback you enter.

What this calculator does

  • Years for a robot project to repay its investment from net savings after ownership cost, checked against your target.

Formula used

  • Net annual savings = annual savings − annual ownership cost
  • Payback period = project investment ÷ net annual savings, blank when net savings is zero or less
  • Five-year net value = net annual savings × 5 − project investment
  • Five-year ROI = five-year net value ÷ project investment × 100
  • Gap to target payback = target payback years − payback period

Inputs explained

  • Project Investment: Robot, EOAT, integration, safety, install and training cost.
  • Annual Savings: Labor and throughput savings the project delivers each year.
  • Annual Ownership Cost: Support, spares, energy and insurance the cell adds yearly.
  • Target Payback: Payback finance requires before the project is approved.

How to use the result

  • Best suited to building a capital case for a robot cell, setting a payback target with finance.
  • Straight payback ignores the time value of money and every cash flow after the payback date.

Current U.S. benchmarks

  • Global copper trades at $13,543 per tonne (IMF via FRED, Jul 2026), up 38.6% in a year, and U.S. industrial electricity averages 9.77 cents per kWh. Both feed electrified-hardware unit economics.

Common questions

  • What counts in annual ownership cost? Support contracts, spares, consumables, energy, insurance and training refreshers the cell adds. A robot with no operator still carries these costs every year.
  • Why does a short payback still show weak ROI? The five-year window is fixed. A project with a large investment and slow early savings can repay late; five-year net value stays small or negative when the horizon is shorter than payback.
  • Is payback or ROI the better screen? Payback answers how long cash stays at risk; ROI answers what the project returns over a set horizon. Finance usually wants both, and a target payback is easier to police than a target ratio.
  • Should I use gross or net savings in the ratio? Net. Ownership cost is a real annual cash outflow, so subtract it first. Entering it separately also shows the size of the recurring commitment rather than hiding it in a smaller savings figure.
