  • Buying beats renting after about 60 months (4.9 years), if the robot lasts that long.

  • Buy
  • Rent (RaaS / lease)
Cumulative cost, before any resale value. Straight lines because the inputs are flat monthly costs.

Before you trust this

  • You haven't added upkeep for buying. Robots are rarely free to keep; a service plan alone can change the answer.
  • You haven't added staff time. When you buy or rent, someone on your side runs the robot; a service includes that.
Show the maths
Buy: £98,000 + (£0 + 0 h × £0) × 36 − £0 = £98,000
Rent (RaaS / lease): £0 + (£1,650 + 0 h × £0) × 36 = £59,400

This is arithmetic on your inputs and the receipts shown, not a quote and not a Whirrwork estimate. Real quotes vary with terms, volume, location and tax.

Next steps

Change your numbers

Buy

You pay once and own the robot. You also pay to keep it running and someone on your side runs it.

Rent (RaaS / lease)

A monthly fee to use the robot yourself, usually with maintenance included. You still run it.

Hire a service

A company brings the robot (or the people) and does the job. You pay per job, per acre, per visit…

No sourced price for this option and job. Type a quote you have, or leave it empty.

How the maths works

Every option is a one-off cost plus a monthly cost, added up over the period you pick. No interest, no inflation, no guesses of ours.

  • Buy: purchase price + (upkeep + staff hours × wage) × months − resale value.
  • Rent (RaaS / lease): setup fee + (monthly fee + staff hours × wage) × months. A yearly fee is divided by 12.
  • Hire a service: service price × how much you need a month × months. The provider's operator is included in their price.
  • Break-even is the month when buying has cost the same as the alternative: purchase price ÷ the monthly saving. Resale is ignored here.

What this leaves out

  • Financing, interest and tax. A lease can be cheaper or dearer than it looks once those are in.
  • Capacity. One robot may not cover your volume, and a service can scale up on a busy week.
  • Downtime, training, and the robot wearing out before the period ends.
  • Prices on public pages are often list or 'from' prices. Your quote may differ.

Which sourced prices count as buy, rent or service was decided by hand (77 receipts, checked 2026-10-27). Read: Robots as a service, explained
