Facebook Ads Calculator

How are Facebook Ads calculated?

Facebook Ads are calculated using five key inputs:

1. Total Ad Spend – how much you spent on your campaign
2. Total Clicks – the number of clicks your ad received
3. Total Impressions – how many times your ad was shown
4. Total Conversions – how many desired actions (like sign-ups or purchases) occurred
5. Total Revenue – the income generated from those conversions

From those, we calculate the following metrics:

• CPC (Cost Per Click) = Total Spend ÷ Total Clicks
  → Tells you how much each click is costing.
• CPM (Cost Per 1,000 Impressions) = (Total Spend × 1,000) ÷ Total Impressions
  → Shows how efficiently you’re getting your ads seen.
• Conversion Rate = (Total Conversions ÷ Total Clicks) × 100
  → Reveals how well your clicks are turning into results.
• ROAS (Return on Ad Spend) = Total Revenue ÷ Total Spend
  → Measures how much revenue you earn for every $1 spent.

This gives you a clear view of performance and profitability — and helps identify which part of the funnel may need optimisation.
