The revenue lab

Put your ambition
through the numbers.

Explore one offer at a time. This calculator models a full year using your assumptions, not an earnings prediction.

For a monthly membership, use monthly price and average paid months per customer. Annual customers are distinct paying customers.

YOUR ILLUSTRATIVE SCENARIO
Annual gross revenue
$100,000
Simplified surplus before tax & omitted costs
$58,000
Annual customers needed for your target
2,000
Average monthly revenue
$8,333

10% of the annual revenue target.

Not owner take-home pay. Assumes all stated purchases occur at the entered price.

How the calculation works

Annual gross revenue = price × customers × purchases per customer. Variable costs = revenue × the entered percentage. Simplified surplus = revenue − variable costs − annual fixed costs. Customers needed = target ÷ (price × purchases), rounded up.

What to include in your assumptions

Estimate payment fees, fulfillment, refunds and other variable expenses in the cost percentage. Include venue commitments, software, staffing or other fixed expenses in annual fixed costs as appropriate. Avoid counting the same cost twice. The tool does not model taxes, financing, timing of payments, customer acquisition funnels, or changing capacity.

Make the scenario useful

Try a conservative version with fewer customers and higher costs. Then ask whether you have the time, demand, and qualified help to serve the volume shown. A negative surplus means the entered costs exceed the modeled sales; it is a signal to revisit the plan.

Understand revenue vs. profit or read the seven-figure business guide before treating a large target as a plan.
