Free, no sign-up, runs in the browser: https://analify-ai.scalyax.ai/tools/ad-frequency-calculator

See how often the same people see your ads, per week and per creative, and how many days each creative has before it hits the limit you set.

## What it calculates

Frequency is impressions divided by reach: the average number of times one person saw your ads. When the same audience sees the same creative too often, clicks drop and costs rise. Spreading frequency across more creatives slows that down. Set the limit that has worked for your own account.

## Formula

```
Frequency = Impressions ÷ Reach
Weekly frequency = Frequency ÷ days × 7
Per creative = Frequency ÷ active creatives
Days to limit = Limit ÷ (Frequency ÷ days ÷ creatives)
```

## Worked example

Inputs:
- Impressions: 500000
- Reach (people): 150000
- Days in the period: 30
- Spend: USD 6,000
- Active creatives: 3
- Your frequency limit: 3

Results:
- Average frequency: 3.33×
- Weekly frequency: 0.78×
- Frequency per creative: 1.11×
- Days until a creative hits your limit: 81 days
- CPM: USD 12
- Cost per person reached: USD 0.04

## What changes the result

Active creatives at five values; every other input as in the example.

| Active creatives | Frequency per creative | Days until a creative hits your limit |
| --- | --- | --- |
| 1 | 3.33× | 27 days |
| 2 | 1.67× | 54 days |
| 3 (example) | 1.11× | 81 days |
| 5 | 0.67× | 135 days |
| 6 | 0.56× | 162 days |

## How to read the result

If days to limit is short, add new creatives or widen the audience before results drop.
Watch CTR and CPM next to frequency. Fatigue shows as falling CTR and rising CPM at the same time.

## Questions

**What is ad frequency?**
The average number of times each person reached saw your ads in a period: impressions divided by reach.

**What frequency is too high?**
It depends on audience size, offer and creative. Find the frequency where your own CTR starts falling and use it as your limit.

**How do I lower ad frequency?**
Add creatives, widen the audience, or lower the budget on a small audience.

**Do you store what I enter?**
No. The calculation runs in your browser and nothing is sent to Analify.
