Before you start

You'll need an accurate cost-per-bar figure for this tool too. If you haven't worked that out yet, start with the Soap Cost & Pricing Calculator first.

Part 1 — Before you apply

Enter the booth fee, your travel cost, and any other one-off costs for this specific event. Then enter your hourly rate and your total time investment — prep, driving, setup, the event itself, and breakdown. Be honest about your hours; this is where most people underestimate. The tool adds it all up into a single fixed cost for the market, then tells you exactly how many bars you'd need to sell just to break even.

Part 2 — After the market

Once the event is over, come back and fill in what actually happened — items sold, actual revenue, actual hours. The tool compares your estimate to your reality side by side, and tells you what you truly earned per hour once every cost is accounted for.

A few things worth knowing

• Duplicate the tab for every market you do (right-click the tab name → Duplicate), so you build a running record you can compare side by side across a full season.
• Time costs add up faster than people expect. An hour of prep, an hour of drive each way, and a six-hour event is eight hours before you've sold a single bar — price that hour at what your time is actually worth, not what feels generous to charge yourself.
• A market that loses money once doesn't necessarily mean skip it forever — sometimes it means adjust your booth setup, your price, or your hours next time. The tool is there to inform the decision, not make it for you.
