Most equipment rental owners track revenue. Some track ROI. Almost nobody tracks utilization rate. This is a mistake, because utilization rate is the metric that tells you whether your inventory is actually working or just sitting on a shelf collecting dust between bookings.
Revenue tells you what came in. ROI tells you how close an item is to paying for itself. But neither tells you how much opportunity you are leaving on the table. That is what utilization rate reveals, and it changes the way you think about every piece of equipment you own.
What equipment utilization rate is
Equipment utilization rate measures the percentage of available days that a piece of equipment was booked during a specific period. The formula is simple:
Utilization Rate = (Days Booked / Days Available) x 100
If your Sony FX6 was available for rental all 30 days last month and was booked for 12 of those days, its utilization rate is 40%. If it was only available for 20 days because you used it on your own shoots for 10 days, and it was booked for 12 of those 20, its utilization rate is 60%.
The distinction between calendar days and available days is important. Equipment you use on your own productions, gear that is in the shop for repairs, and periods where you have intentionally blocked bookings should be subtracted from the available-day count. Utilization calculated against available days gives you an accurate picture of rental demand relative to actual availability.
How to calculate it correctly
The concept is straightforward. Getting an accurate number requires attention to a few details.
Choose a meaningful time period
Monthly utilization is useful for spotting trends. Quarterly utilization smooths out noise from slow weeks and busy weekends. Annual utilization is the most reliable number for making buy, hold, or sell decisions.
Calculate all three, but do not react to a single bad month. A camera that had 10% utilization in January might be at 45% for the quarter if February and March were strong. Seasonal trends in camera rentals cause significant monthly variation that quarterly and annual numbers absorb.
Count actual booked days, not shoot days
A Sharegrid booking from Friday through Monday is four calendar days of utilization, not two shoot days. The equipment was unavailable for four full days, so count all four. This is the booking's footprint on your calendar, and it is what matters for utilization.
If you are using a bookings calendar to visualize your rental schedule, the booked-day count should be straightforward. Count every day the gear was checked out, from pickup through return.
Define available days honestly
This is where most owners get the calculation wrong, usually by being sloppy rather than dishonest.
If you blocked two weeks for a personal project, those 14 days are not available. If a lens was in for repair for a week, those 7 days are not available. If you took December off entirely, those 31 days are not available.
Being precise about available days makes your utilization number more useful. A camera at 20% utilization over 365 available days has a different problem than one at 20% over 200 available days. The first has plenty of demand opportunity and is not capturing it. The second has limited availability and may actually be performing fine within its constraints.
Calculate at the item level
Portfolio-wide utilization averages are useful as a summary metric, but the real insights come from item-level comparisons. Your highest-revenue item might not be your most-utilized item, and that gap tells you something important.
What good utilization looks like
Benchmarks vary by equipment category because demand patterns, price points, and competitive dynamics differ.
Camera bodies
Strong: 25% to 40% (8 to 12 days per month). This is excellent performance for a camera body. Consistently hitting this range means the item is in genuine demand in your market. Very few camera bodies sustain above 40% utilization over a full year.
Average: 15% to 25% (5 to 8 days per month). Generating income regularly but with room for improvement. Consider whether pricing adjustments, better listing photos, or market positioning could push this higher.
Below target: Under 15% (fewer than 5 days per month). At this level, the camera is not booking often enough to reach payback before significant depreciation occurs. Evaluate whether the pricing is competitive, whether local demand exists for this model, and whether the capital would perform better in a different item.
Lenses
Strong: 20% to 35%. Lenses typically book as part of packages, so their utilization is often tied to the camera body they pair with. A frequently paired lens benefits from the camera's demand. Prime lenses in popular mounts tend toward the higher end.
Average: 10% to 20%. Decent for a lens, especially specialty or niche focal lengths. Lenses hold their value well, so moderate utilization combined with low depreciation can still produce good ROI.
Below target: Under 10%. Consider whether this lens fills a genuine gap in your lineup or whether it is redundant with other items in your inventory.
Lighting and grip
Strong: 15% to 30%. Lighting gear tends to book for multi-day productions, which inflates individual booking length but limits total booking count. A light kit that goes out for a week at a time might only book three or four times per month but still achieve 25% or higher utilization.
Average: 8% to 15%. Competitive category with many owners listing similar gear. Differentiation through kit completeness (stands, modifiers, cases) can push utilization higher.
Audio
Strong: 20% to 35%. Wireless microphone systems and sound kits see consistent demand from a wide range of production types.
Average: 10% to 20%. Specialty items like boom poles or specific recorder models will skew lower.
Why a high utilization rate is not always good
This is counterintuitive, but a utilization rate that is too high can indicate a problem.
You might be priced too low
If your camera body is booked 50% of available days, you are almost certainly leaving money on the table. At that booking frequency, raising your daily rate by 10% to 15% would likely reduce bookings slightly but increase total revenue. Some renters are choosing your listing specifically because it is cheaper than comparable options.
A camera booked 15 days per month at $150 per day earns $2,250. That same camera booked 12 days per month at $180 per day earns $2,160. Close to the same revenue with three fewer days of wear, tear, and handoff logistics.
Wear and tear accelerates
Every rental day puts hours on your gear. Sensor cleaning, body wear, adapter connections, and general handling stress accumulate. A camera at 50% utilization is going through twice the physical wear of one at 25%. If the revenue difference does not compensate for the accelerated depreciation and maintenance costs, the higher utilization is actually reducing your net return.
Availability for your own work
If you use your equipment for personal or paid productions, ultra-high rental utilization means your gear is never available when you need it. Many owners list equipment they also use professionally. For them, the ideal utilization is not the maximum possible but the maximum that still leaves enough availability for their own work.
Why a low utilization rate is not always bad
The inverse is also true. Low utilization does not automatically mean an item is underperforming.
High daily rate items earn more per booking
A RED V-RAPTOR at 15% utilization might earn $4,500 per month on just four or five bookings. A Sony FX3 at 40% utilization might earn $2,400 per month on twelve bookings. The V-RAPTOR has lower utilization but higher revenue because its daily rate is four times higher.
Low utilization is only a problem when it results in low total earnings relative to the item's cost. Tracking ROI alongside utilization gives you the complete picture.
Seasonal items perform in bursts
Some equipment has inherently seasonal demand. Underwater housings, aerial rigs, and specialty lenses may sit idle for weeks and then book heavily during a production season. Annual utilization might look low, but the items generate strong revenue during their active periods.
New listings need ramp time
A freshly listed item has zero reviews and low search ranking. Utilization in the first one to three months is not representative. Give new listings at least a quarter before evaluating utilization meaningfully.
How to use utilization for inventory decisions
Utilization rate becomes powerful when you combine it with other metrics to make specific decisions about your equipment portfolio.
Identifying dead weight
An item with low utilization (under 10%) and low ROI (under 30% payback after a year) is a candidate for selling. The capital locked in that item could be redeployed into equipment with higher demand.
Before selling, check whether the low utilization is a pricing problem or a demand problem. Drop the price by 10% for a month. If bookings increase, the issue was pricing. If they do not, the market does not want that item at any reasonable price.
Deciding what to buy next
Look at your highest-utilization items. If your Sony FX3 is consistently above 35% utilization and frequently unavailable when renters inquire, adding a second FX3 could capture revenue you are currently turning away. The same applies to popular lenses and accessories.
Conversely, do not buy more of what is not booking. If your ARRI Signature Primes are at 8% utilization, buying another prime lens in that mount is adding capital to a category with proven low demand in your market.
Optimizing packages
High-utilization items that frequently book together are natural package candidates. If your camera body and a specific lens consistently go out on the same bookings, bundling them as a kit can increase average booking value while maintaining the same utilization. The utilization metric that most rental owners ignore goes deeper into how this analysis works.
Improving utilization without lowering prices
Dropping your daily rate is the laziest way to increase utilization, and it usually backfires because it trains the market to expect lower prices and reduces your revenue per booking.
Here are better approaches.
Improve listing quality. Better photos, more complete descriptions, and accurate accessory lists make your gear more attractive at the same price point. Many bookings are won or lost on listing presentation.
Respond faster. Renters often message multiple owners simultaneously. The first person to respond frequently wins the booking. Responding within an hour instead of within a day can meaningfully increase your booking rate.
Offer packages. Bundling a camera body with commonly requested accessories as a single listing makes your offering more convenient and increases the total booking value.
Adjust minimum rental periods. If one-day booking requests are not worth the handoff logistics, set a two-day minimum. This increases revenue per booking and may attract renters looking for multi-day availability.
List on additional platforms. If you are exclusively on Sharegrid, expanding to direct bookings or other platforms increases your exposure. More visibility with the same inventory means higher utilization.
Tracking utilization over time
A single utilization snapshot is interesting. Utilization tracked over time is actionable. Plot quarterly utilization for each item and you will see which items are trending up (growing demand), trending flat (stable), and trending down (fading relevance).
Items with declining utilization over multiple quarters are sending a clear signal: the market for that equipment is softening, competition has increased, or a newer model is capturing demand. These trends tell you when to sell before depreciation compounds the loss. Items with rising utilization are your growth opportunities.
Utilization rate is not the only metric that matters. But combined with revenue, payback progress, and depreciation estimates, it gives you a complete picture of whether each piece of equipment is earning its keep or costing you money by sitting idle.
