Estimate a year of rental revenue from what your inventory bills in a full week, how much of it goes out in and out of season, and what delivery adds. The arithmetic from our party rental revenue guide, with your numbers in it.
A rental business’s revenue is the product of four things: what the whole inventory would bill if every item went out for a week at list price (the billing capacity), the share of that capacity that actually rents (utilization), how many weeks are in season and off season, and what delivery and add-ons contribute per order. Nothing else matters as much, and every one of them is a number you can find or decide.
The calculator multiplies them out and shows the year in season and off season, delivery revenue on top, and what is left after a per-order cost for crew, cleaning and truck time. Change one input at a time and watch which lever moves the total: for most businesses it is utilization and average order value, not inventory size.
Use it before buying stock. Doubling inventory only doubles revenue if utilization holds; one high-margin item that rents every weekend often does more than another hundred chairs.
Add up what every item you own would bill for one week at your list price (day rate × your standard rental days, or the event-window price). It is the ceiling for a week.
No. It is your inventory and your assumptions. The defaults are an example and should be replaced.
Crew hours, truck time, cleaning, consumables and the occasional missing item, expressed as a percentage of the order or a flat amount. Fixed costs (rent, insurance, software) sit outside the calculator.
