Laundry Vending Revenue Calculator

The calculator only takes detergent and softener mix percentages as inputs, then computes dryer sheets as whatever share of vends is left over — 100% minus the other two. This guarantees the three product shares always sum to exactly 100% without you having to manually balance three numbers, though it means you can't model a scenario where all three categories are set independently.

The engine multiplies your single COGS percentage against total combined revenue from detergent, softener, and dryer sheets together, rather than tracking a separate wholesale cost for each product. This keeps the model simple but means it can't capture a real-world situation where, say, detergent pods cost proportionally more to source than dryer sheets — for that level of precision you'd need to average your actual blended cost percentage across the specific mix you're running.

Machine lease is a per-machine monthly fee (multiplied by the number of machines at the location) that applies only if you don't own the machines outright — set it to 0 if you do. Restocking cost is unrelated to ownership: it's the labor and travel cost of your visits to refill supplies, calculated as visits per month times your cost per visit, and applies regardless of who owns the hardware.

Both metrics normalize the results so you can compare locations of different sizes on equal footing — profit per vend shows how much each transaction actually nets after all three expense categories, while revenue per tenant shows how much each unit or resident generates on average per month. Since vend frequency and product mix are estimates you supply rather than observed sales data, treat early comparisons as rough rankings and refine the inputs once a location has real transaction history.
