Why measure ROI

ROI (Return on Investment) is the single most important marketing metric. It's the difference between "I feel like it's working" and "it's working at X%." Without ROI, you're shooting in the dark and burning budget.

The formula

ROI = (revenue from the campaign - campaign cost) / campaign cost × 100%

ℹ️
Example: you invested $290, and got back $1,450 in revenue. ROI = (1,450-290)/290 × 100% = 400%

What to include in your cost side

  • Tool cost (Natural Poster — starting at $39/identity)
  • Your own time (hours × $/hour)
  • Graphic design (if you invested in it)
  • Image hosting
  • Paid ad spend (if any)

What to include in your revenue side

  • Direct sales from leads
  • New customers × average LTV
  • Retention of existing customers
  • Indirect gains (brand awareness)

A real-world example — a real estate agency

A local real estate office. Monthly investment: Natural Poster ($49) + time (10 hours × $29 = $290) = $339.

Results: 20 inquiries, 2 closed deals, average commission $4,300 = $8,600.

ROI = (8,600 - 339) / 339 × 100% = 2,437% (roughly 24x return on investment)
