This is a cost-only break-even model. It does not claim that a reusable product has lower environmental impact; lifespan, washing, materials and disposal can materially change environmental results.
How to use this calculator
What to enter
Enter or select the following as requested: Reusable product cost; Disposable cost/use; Currency; Reusable cost per use. Follow the units, valid ranges, examples, and options displayed beside each field.
What the result means
The break-even output estimates the sales revenue or sales quantity at which the costs represented by the inputs are covered, with no profit or loss at that point. Check whether the output is money or units and whether fixed and variable costs use the same period.
When to use it
Use this to estimate a cost-coverage target under the assumptions entered. It is a scenario calculation, not a demand or revenue forecast.
