F = I / U

  • Where F is the frequency

Next, determine the number of unique users that saw the impressions. For this example, 1,000 people saw the

Next, calculate the frequency using the formula above:

F = I / U = 100,000 / 1000 = 100 (frequency).

Finally, from the frequency and the number of unique users, the reach can be calculated.

R = I / F = 100,000 / 100 = 1000 reach
