Robot mower ROI calculator
A robot mower is a big up-front cost that quietly saves money — or time — every week after. This works out when it crosses into the black against what you do today.
When does a robot mower pay for itself versus what you do now? Defaults are typical GBP figures — edit them to your situation.
Simple un-discounted cash comparison. It ignores resale value, battery replacement and the robot's effect on lawn quality. Use it to gauge payback order-of-magnitude, not to the penny.
Reading the result
If you currently pay a gardener, the robot competes directly on cash, so payback is usually a few seasons. If you mow yourself, the "saving" is the value of the hours you get back — set that to whatever your weekend is worth to you. The model is deliberately simple: undiscounted cash, no resale value, no battery replacement. It answers "roughly when does this stop costing me money", which is the question most buyers actually have.
