What this calculator estimates
Estimate Facebook or Meta Ads traffic, conversions, revenue, ROAS and ROI from spend, CPM and conversion assumptions. It is designed for fast planning and comparison in the United States. The output is an estimate, not a binding quote, approval, tax determination, insurance offer, legal conclusion, medical recommendation or professional advice.
How to use it
Enter the requested values using a single consistent time period and currency. Select Calculate, review the headline result and supporting figures, then change one assumption at a time to compare another scenario.
How the calculation works
The calculator estimates traffic from the entered cost metric, applies click-through and conversion assumptions, then calculates revenue, gross profit and ROI after advertising and other costs.
Important limitations
Attribution, platform reporting, view-through conversions, refunds, repeat purchases, taxes, creative fatigue and incrementality can change actual results.
