What would the experiment need to earn?
Explore your assumptions before deciding what to spend. This calculator does not predict sales or measure your business’s actual profit.
The calculation.
Contribution per sale = sale price − delivery cost per sale. Incremental contribution = additional completed sales × contribution per sale.
Estimated net benefit = incremental contribution − subscription cost − other incremental costs. Break-even additional sales = total incremental costs ÷ contribution per sale, rounded up to a whole sale.
What the numbers leave open.
Include all relevant incremental costs. Fixed overhead, tax, owner time, financing, and changes to existing sales may also matter. Freed capacity is not automatically cash savings. Review fulfillment capacity and a zero-sale case; software alone does not cause the outcome.
