Ad frequency calculator
Frequency is how many times the average person saw your ad: impressions divided by reach. Too low and the message does not land; too high and you are paying to annoy the same people while CPMs rise. Solve it any way and read the fatigue risk.

What is ad frequency?
Frequency is the average number of times each person saw your ad over a period: impressions divided by reach. It is the early warning system for creative fatigue. As the same people see an ad again and again, response falls, CPMs climb and CTR drops.
How to calculate frequency
What is a good frequency?
| Frequency | Read |
|---|---|
| 1 to 2 | Healthy for cold prospecting |
| 3 to 4 | Danger zone on prospecting, fatigue likely setting in |
| Higher | Often fine for warm retargeting, where repetition is expected |
How to manage frequency
- Refresh creative before fatigue, not after. Rising frequency with falling CTR is the cue.
- Widen the audience or raise budget headroom so the same people are not hit repeatedly.
- Separate prospecting and retargeting; judge frequency against the audience, since retargeting tolerates more.
The operator’s playbook
How a paid-media operator reads this number, not a glossary definition.
Frequency is the early warning for fatigue+
As frequency climbs on the same audience, CTR falls and CPM rises, so your CPA quietly worsens. Watch frequency per audience, not account-wide: 1 to 2 is fresh, 3 to 4 is the danger zone for cold prospecting, higher is usually wasted unless it is tight retargeting.
When high frequency is fine+
Warm retargeting and small, high-intent audiences tolerate (and need) higher frequency. Cold prospecting does not. Judge frequency by the audience and the trend in CPM and CTR, not a single number.
Frequently asked questions
How do you calculate ad frequency?
+
Impressions divided by reach. 180,000 impressions across 60,000 people is a frequency of 3. This tool also solves for the impressions or reach behind a target frequency.
What is a good ad frequency?
+
For cold prospecting, 1 to 2 is healthy and 3 to 4 is where fatigue tends to start. Retargeting tolerates more. The real signal is rising CPM and falling CTR as frequency climbs.
What is ad fatigue?
+
When the same people see your ad too often, response falls: CTR drops, CPM rises and cost per result climbs. Rising frequency is the early warning.
What frequency is too high?
+
On cold prospecting, a frequency above 3 to 4 usually signals fatigue. Warm retargeting audiences tolerate more, since repetition is expected there.
How do I reduce ad frequency?
+
Refresh creative, widen the audience, add a frequency cap, and keep prospecting and retargeting separate so you are not over-serving the same people.
