Calculate net cash flow—not just sales.
Change every assumption. The result separates gross revenue, variable costs, estimated monthly net cash flow, and simple machine payback.
Build a scenario.
Gross revenue
Sales per day × average sale × operating days. This is top-line activity, not profit.
Variable costs
The calculator applies product cost, card fees, and venue share to revenue. If your venue share is based on gross profit or a fixed rent instead, convert it into the most realistic monthly-cost assumption you can.
Estimated net cash flow
Gross revenue minus variable costs and the monthly fixed-cost input. Include route labor even when you perform it yourself if you want the model to remain comparable as the route grows.
Simple payback
Machine/setup cost divided by estimated monthly net cash flow. This ignores the time value of money, financing, taxes, major repairs, and changing demand. Treat it as one scenario metric, never a promise.
