How these numbers are calculated
  • Leads = visitors × visitor-to-lead rate. Customers = leads × close rate. Revenue = customers × average customer value.
  • Projected visitors = current visitors × (1 + traffic increase). Projected conversion = current rate × (1 + conversion increase), capped at 100%.
  • Additional revenue = projected revenue − current revenue. Revenue-based return = (additional monthly revenue − monthly investment) ÷ monthly investment.
  • Payback = one-time build cost ÷ (additional monthly revenue − monthly investment).
  • This is revenue, not profit. Profit figures only appear when you enter a margin. Scenario increases are editable examples, not promises.

FAQ

About this calculator

Is this a guarantee?

No. It's an estimate based on the numbers and assumptions you enter. Real results depend on your market, offer, competition and follow-up.

Are the industry numbers real averages?

No. They're example starting values so the calculator isn't blank. Replace them with your own numbers for a useful estimate.

Why revenue and not profit?

Revenue is what customers pay you. Profit is what's left after costs. Unless you enter a profit margin, the calculator only shows a revenue-based return and never calls it profit.

What if I don't have a website?

Your current website visitors are zero, so the projection uses a hypothetical visitor count you choose. It's labeled as hypothetical everywhere it's used.
