Your overhead are things that, most of the time, are over your head. That could include your shop (the roof is over your head), your accounting (because it’s over your head), your marketing costs, your website, or your Stemcounter.com subscription (wink wink). Basically, anything that doesn’t have to do with the event and services you don’t do yourself. For this example, let’s say that you had $30,000 of overhead. Your overhead divided by 100 events would be $300 per event.
