Rental Cost
For the days you need it.

Usage Tip

Rent the big, expensive, rarely used machines (tile saws, augers, floor sanders) and buy the tools you will reach for again and again. Reserve rentals ahead for busy weekends.

THE MATH
Rental cost = daily rate × days
Net cost to buy = purchase price − resale value
Break-even days = net buy cost ÷ daily rate
Renting suits one-off jobs; buying pays off when you will reuse a tool or need it long enough that rental fees exceed the purchase price.
Break-even days is the rental duration that equals the cost of buying — rent for less, buy for more.
Buying adds hidden costs: storage space, maintenance, and the tool sitting idle between jobs — renting offloads all of that.
Renting adds its own friction: pickup and return trips, deposits, and the clock running on weekends and holidays.
For specialty or rarely used tools, renting almost always wins; for everyday tools you will reuse, buying pays back fast.
