A campaign can produce sales and still fail to cover its cost. Revenue alone is not enough to judge the result. This calculator uses the contribution remaining after variable fulfillment costs to estimate the minimum incremental sales needed to break even.

For illustration and planning only. Results depend entirely on your assumptions and do not guarantee revenue, savings or outcomes. Do not count recovered labor time as cash savings unless staffing costs actually change.
Why contribution margin matters
If a product sells for $150 but its variable costs consume $90, there is $60 left to contribute toward marketing and other fixed costs. Counting the full $150 toward advertising payback would overstate the economics. For services, include the direct costs required to deliver each additional job.
Do not mistake attribution for incrementality
Sales credited to a campaign may have happened anyway. Use the model for planning, then compare it to actual incremental demand, customer quality, return behavior and the cost of acquiring those customers.
Useful next steps
- Estimate gross contribution with current product or service economics.
- Separate new customers from repeat or existing demand.
- Track the entire path from lead source to accepted order.
- Revisit the model when prices, fulfillment cost or conversion change.
