Worked example
A $400 robot vacuum that saves 30 minutes of vacuuming a week saves 26 hours a year. Valued at $15 an hour that is $390.00. Filters, brushes and electricity cost $45 a year, so the net gain is $345.00 a year and the payback is $400 / $345.00 = 1.16 years (13.9 months). Over a 5-year life you finish $1,325.00 ahead. If you value your time at $0 and save nothing else, it never pays back in money; a robot vacuum then has to earn its place by convenience. A different case: a $500 robot that lets you cancel $250 a year of cleaning visits pays back in 2.0 years. These are example inputs: replace them with your own.
How it works
Net per year = (minutes saved per week x 52 / 60 x hourly value) + service cost avoided - upkeep - electricity. Payback = price / net per year. Net over its life = net per year x years + resale value - price.
Honest limits. Whether your time has a dollar value is your call, so the tool lets you set it to 0. Minutes saved is also yours to estimate: a robot does not necessarily replace every manual pass, so count only the time you really stop spending. The expected life is a guess you set; battery replacement is the usual wear item and belongs in upkeep.

FAQ
Is a robot vacuum worth it?
It depends on the time it really saves you and what you value that time at. Enter both and the calculator shows the payback and the net result over its life.
How long does a robot vacuum last?
There is no single figure; it varies by model and use, so you enter the life you expect. Battery replacement is the usual cost to add under upkeep.
What should I count as upkeep?
Replacement filters, brushes, bags or mop pads, batteries and the electricity it uses, as a yearly total.
What if I value my time at zero?
Then the only savings are cash ones, like cancelled cleaning visits. A robot vacuum usually does not pay back in cash alone.
Does it replace regular vacuuming?
Usually not entirely. Count only the minutes you stop vacuuming, not the whole task.
