WHO THIS IS FOR
Anyone who signs the budget at an organization that files a Form 990 - chief financial officer, controller, vice president of finance.
WHAT THE LINE IS
On Part IX of the return this is a single reported total. It usually holds more than its name suggests, and it is rarely reviewed as a category, because no one invoice inside it is large enough to get attention.
WHY IT MATTERS
Across 3,358 filed returns, the 25th percentile reports 1.12% of total revenue on operating supply. The middle reports 2.44%. The 75th reports 5.13%. That is 4.6 times, on one line, between organizations doing the same work. The median filer reports about $638,716 a year here. The gap opens for a structural reason rather than a careless one: a line nobody reviews as a category renews on whatever price it was last set at.
That range is not evidence that anyone is badly run. An organization running residential, food or clinical operations consumes on a different scale than one running programs from an office — correctly.
HOW TO TELL IF IT MEANS ANYTHING TO YOU
Two minutes. Find the operating supply total on your most recent Form 990, Part IX. Divide it by total revenue. Under 1.12% and you are in the tightest quarter of filers - you are fine. Between 1.12% and 2.44% and you are better than the middle. Above 5.13% and you are in the top quarter, which is worth an explanation - and there may well be a good one.
Do you know which end you are on, and can you say why?
The benchmark is a reason to ask why, not a conclusion that something is wrong. Operating context still determines whether a category is worth pursuing.
