ROI on collaborative robots — a practical guide for SMEs
Most small and mid-sized manufacturers we meet are convinced that cobots make sense — they're just not sure how to put a number on it. This guide walks through the exact framework we use with first-time buyers to estimate payback, productivity uplift and total cost of ownership before a single bolt is tightened.
1. What a cobot actually costs
A first cobot cell rarely lives or dies on the robot price. The arm itself is typically 25–40% of the total. The rest is end-effector, safety, fixturing, integration hours, programming and training. Budget realistically and the payback math gets honest.
2. The payback formula
Strip away the spreadsheets and cobot ROI comes down to one line:
Most first cells we ship to SMEs land between 14 and 22 months of payback. Anything under 24 months on a single-shift operation is a green light. Under 12 months usually means you're moving to two or three shifts on the same cell — which is exactly where cobots shine.
3. Where the savings come from
- Labour reallocation. A cobot tending a CNC overnight frees an operator to run a second machine during the day. You rarely fire anyone — you grow without hiring.
- Throughput uplift. Cycle times tighten by 8–18% because the cobot doesn't take breaks, doesn't drift, and doesn't drop parts.
- Scrap reduction. Repeatable placement and force control typically cut scrap on assembly and machine tending by 20–40%.
- Capacity unlock. Running a third shift unattended on the same floor space is usually the single biggest financial lever.
4. A worked example
A 28-person contract machinist in Sweden adds a UR10e cell for CNC tending on a mid-volume aluminium part.
5. The mistakes that kill ROI
- Picking the wrong first application. Start with high-mix, repetitive, dull or dirty — not your most complex job.
- Skimping on fixtures. A €2,000 saving on fixturing can cost €20,000 in lost cycle time.
- No operator buy-in. The shop floor must want the cobot. Involve them on day one.
- Ignoring service. A cobot that's down for two weeks erases six months of payback.
