Equipment utilization calculator.

Why utilization matters more than you think.

Utilization is the single number that connects your fleet size to your revenue. Every yard knows it matters. Very few yards track it the same way twice.

Time utilization and dollar utilization are different things. Time utilization tells you what percentage of available unit-days were on rent. Dollar utilization tells you what percentage of theoretical revenue you actually collected. A unit sitting on a frac pad at 60% standby still shows up in time utilization but counts differently on the dollar side. Both numbers matter. Most yards only pull one — usually from a spreadsheet.

The rule of thumb in oilfield rentals is 60–65% time utilization for a healthy single-location yard. Below 55%, you have more iron than your market can absorb right now. Above 70%, you’re turning away work or pushing delivery windows out far enough to lose bids. The window is narrow. Knowing where you sit every week changes how you sell, price, and buy.

Most yards running 70% time utilization on paper are still leaking dollar utilization if MSA overrides aren’t tracked properly. A customer on a 15% master service agreement gets billed book rate because the dispatcher didn’t pull up the contract. That mistake doesn’t show in time utilization at all — it shows up in dollar utilization six weeks later when someone reconciles the spreadsheet. EquipFlow’s billing module pulls MSA rates from the customer record automatically so the denominator is always correct.

What do you do with the number? If you’re under 55%, look at your inactive units in inventory — some are candidates for retirement or remarketing. If you’re at 65–70% and healthy, the lever is pricing: your book rate on high-demand classes may be undermarket. Above 75%, the question is whether you can get more units on the ground before the next bid cycle.

How yards usually get this wrong.

Three patterns we see, every yard:

1. Counting “ready” days as utilized. Unit came off rent Friday. Shop checked it out Monday. Those three days show as available in most spreadsheets — but the dispatcher mentally marks them as “in service.” Utilization looks higher than it is. The yard orders more units based on inflated numbers.
2. Ignoring standby days. A manlift on standby at a frac pad is generating revenue. It is not generating rented hours. If your utilization formula counts only active run hours, standby looks like dead time and your rate looks artificially low. The fix is tracking billed unit-days, not billed run hours, as the numerator.
3. No MSA adjustment in the denominator. Dollar utilization compares actual revenue to theoretical max at book rate. If 40% of your fleet is on MSA contracts at 10–18% discounts, your theoretical max is not fleet × period × book rate — it’s lower. Overstating the denominator overstates the revenue leak. You end up chasing a gap that isn’t really there while missing the real one.
