Reach and frequency calculator

We believe people need to see your campaign about 10 times before it moves them. Enter a budget to see how many people it reaches, or an audience to see the budget it needs, at light, medium and heavy frequency.

Solve for

40,000

Each person sees your campaign 10 times, about once every 3 days.

How it works

Reach versus frequency

A budget buys a fixed number of impressions. Frequency decides how they are shared out: each extra exposure per person means fewer people reached.

Example: $10,000 at a $25 CPM buys 400,000 impressions. At a frequency of 10 that reaches 40,000 people; at 20, 20,000; at 30, 13,333.

Impressions= Budget ÷ CPM × 1,000
Reach= Impressions ÷ (Frequency × Months)
Budget= Audience × Frequency × Months × CPM ÷ 1,000

Reach and frequency questions

What is ad frequency?

Frequency is the average number of times each person sees your ads during a campaign. It equals impressions divided by reach: 400,000 impressions seen by 80,000 people is a frequency of 5.

How do I calculate reach from a budget?

First work out impressions: budget ÷ CPM × 1,000. Then divide by the frequency you plan for. A $10,000 budget at a $25 CPM buys 400,000 impressions; at a frequency of 10 that reaches 40,000 people.

How much budget do I need to reach an audience?

Multiply the audience by the frequency and the CPM, then divide by 1,000. Reaching 50,000 people 10 times at a $25 CPM takes 50,000 × 10 × $25 ÷ 1,000 = $12,500.

What is the difference between reach and impressions?

Reach counts unique people. Impressions count every time the ad is shown. One person who sees an ad three times is one person reached and three impressions, so reach is always equal to or lower than impressions.

What frequency should I plan for?

We recommend at least 10 views per person a month. Below that, people may not see your campaign often enough to remember it. The calculator has shortcuts for three tiers, light (10), medium (20) and heavy (30) views a month, or you can type your own. Longer campaigns multiply it: two months at 10 a month is 20 views per person. Higher frequency repeats the message to fewer people; lower frequency spreads the same budget across more people. At higher frequencies, we recommend rotating several ads so people do not tire of seeing the same one.

Is this a forecast?

No. The calculator assumes the whole budget delivers at the CPM you enter, over the campaign length you pick, with impressions spread evenly at each frequency. It starts at a $25 CPM, a typical planning figure for connected TV. Real delivery depends on audience size, inventory and targeting.
