How is marketing ROI calculated?

ROI = (revenue − cost) ÷ cost × 100. ROAS = revenue ÷ ad spend. ROI accounts for cost as profit; ROAS is a gross revenue multiple.

What is a good LTV:CAC ratio?

Roughly 3:1 or higher is considered healthy. Around 1:1 means you break even on acquisition; below that you lose money per customer.

Divide your target leads by the landing-page conversion rate to get required clicks, then multiply by your average cost per click.
