How do yo use the ROI Calculator
The biggest hesitation most buyers have about robot mowers is the upfront cost. This calculator answers the question that actually matters: how long until it pays for itself?
Start by entering your current lawn service costs. Input what you pay per visit and how many times per year you use the service then the calculator works out your annual spend automatically. Then use the slider to record how many hours per week you currently spend mowing if you do it yourself. Even if you hire a service, this number matters because it reflects the time value you’re recovering.
Next, enter the price of the robot mower you’re considering and an estimate for annual maintenance — blade replacements and occasional cleaning typically run $50 to $120 per year. If you plan to keep partial lawn service after buying (for edging or cleanup, for example), use the final slider to reflect that percentage.
The calculator instantly shows your annual net savings, your payback period in months, and your total five-year net savings. The year-by-year bar chart shows exactly when you cross into profit. The bars turn green once you’ve recovered the upfront investment. The verdict message adjusts based on your numbers, giving you an honest read on whether this is an excellent investment, a solid long-term decision, or a slower return.
For large sloped properties where lawn service costs $100 to $250 per visit, most buyers break even within 12 to 18 months.
