How the calculator works

At the example $500 revenue LTV, the presets model roughly 1×, 1.5×, and 4.3× lifetime ROAS. These are planning assumptions, not measured campaign results. A 1× return covers ad spend only; profitability also depends on delivery costs. Changing the inputs changes each scenario’s return.

Clicks = budget ÷ cost per click. For each following stage, multiply the previous count by the conversion rate. Sales × revenue LTV per customer = lifetime revenue. Lifetime ROAS = lifetime revenue ÷ ad budget. Calculations use unrounded values.

The $500 revenue LTV is an unvalidated example. Replace it with the average total revenue you expect from a paying customer. Lifetime ROAS does not show first-month cash flow or payback time. Changing currency changes the label only.
