How to use this calculator

  • Enter campaign budget.
  • Enter expected CPM.
  • Add average frequency to convert impressions into unique reach.
  • Enter audience size to evaluate saturation risk.

What the result means

Reach estimates the number of unique people exposed to your ads. It is especially useful for awareness, remarketing, and upper-funnel planning.

Impressions = Budget ÷ CPM × 1,000; Reach = Impressions ÷ Frequency

More reach is not always better if the audience is too broad or not relevant. Compare reach with CTR and conversions.

Example calculation

With a $1,000 budget, $5 CPM, and frequency of 2, estimated impressions are 200,000 and reach is 100,000 people.

Tips for better results

  • Keep frequency under control to avoid ad fatigue.
  • Refresh creative for repeated exposure.
  • Expand audience if saturation is high.
  • Use CTR to verify that reached users are responding.
