Tool rental vs purchase cost, with resale and maintenance included
Most rent vs buy calculators compare the rental bill with the sticker price. That overstates the cost of owning: a tool you sell afterwards costs its price minus resale, plus upkeep while you have it. This calculator counts all of it, picks the cheapest mix of rental rates for each job (a 10 day job is a week plus 3 days, not a week), adds the damage waiver, and shows the use count where buying starts to win.

The rent vs buy formulas
Net cost to own = price + (price x upkeep % x years) + storage - (price x resale %).
Rent per job = cheapest of the 4-hour, day and week rate mix for the job length, x (1 + waiver %) + delivery.
Total rent = rent per job x number of jobs. Break-even jobs = net cost to own / rent per job, rounded up.
Cost per use is each total divided by the number of jobs. Rental rates vary 20 to 40% by region, so use your local quote.
Worked examples
One bathroom floor: rent the tile saw
- Rent. 2 days at $65 plus a 12% waiver = $146.
- Own. $450 + $113 upkeep - $180 resale = $383.
- Verdict. Rent and save $237. Buying only pays off at 3 jobs.
Pressure washer 4 times a year: buy it
- Rent. $90 a day with the waiver, x 20 uses over 5 years = $1,792.
- Own. $400 + $100 upkeep - $160 resale = $340.
- Verdict. Buy and save $1,452. It pays for itself by use 4.
