How many dumpsters do you actually need?
Too few dumpsters and you're turning away booked revenue. Too many and steel sits idle depreciating. The math is simple: jobs per month, rental length, turnaround time, and a buffer for reality.
Rule of thumb: jobs per month × cycle days ÷ 30 = dumpsters occupied on an average day. The buffer covers demand spikes, repairs, and the dumpster that always comes back late.
Reading the result
If your expected utilization comes out above ~85%, you'll feel it: no slack for spikes, repairs, or the customer who keeps the dumpster an extra week.
Live availability math is built into DumpsterOS booking — it counts your real fleet minus every reservation, so you can run tighter without overselling.
