Measure ad exposures across audiences, insertions, and channels. Compare scenarios, save reports, and inspect visuals. Plan stronger campaigns using clear metrics and practical benchmarks.
Use the fields below to estimate audience exposure, delivery quality, spend efficiency, and viewable volume for a campaign.
The chart compares the main exposure stages so you can see the gap between scheduled, delivered, and viewable inventory.
| Metric | Example Value | Notes |
|---|---|---|
| Audience Size | 500,000 | Total target audience for planning. |
| Reach Percentage | 65% | Estimated share of audience touched. |
| Average Frequency | 3.2 | Average exposures per reached person. |
| Placements | 4 | Channels or insertions used. |
| Ads per Placement | 2 | Creative slots per placement. |
| Campaign Days | 7 | Repetition duration in days. |
| Delivery Percentage | 92% | Served share of scheduled volume. |
| Viewability Percentage | 68% | Visible share of delivered ads. |
| Estimated Gross Impressions | 5,824,000 | Illustrative total exposures before viewability filtering. |
Gross impressions estimate total ad exposures across all placements and repetition cycles. This calculator uses a layered approach for planning and reporting.
Reached Audience = Audience Size × (Reach % ÷ 100)
Scheduled Exposure Pool = Reached Audience × Average Frequency
Gross Impressions = Scheduled Exposure Pool × Placements × Ads per Placement × Campaign Days
Delivered Impressions = Gross Impressions × (Delivery % ÷ 100)
Viewable Impressions = Delivered Impressions × (Viewability % ÷ 100)
CPM = Media Spend ÷ (Gross Impressions ÷ 1,000)
GRP Estimate = (Gross Impressions ÷ Target Population) × 100
Gross impressions count every possible exposure. They do not remove duplication, so one person seeing the same ad several times increases the total.
Gross impressions represent the total number of ad exposures generated by a campaign. They count every appearance, including repeated views from the same person across placements, days, and formats.
Reach estimates how many people were touched at least once. Gross impressions count all exposures, so repeated views increase impressions without increasing unique reach.
Delivery percentage helps model underdelivery or overdelivery against the scheduled plan. It turns theoretical gross volume into a more practical served-impressions estimate.
Some served ads never become meaningfully visible. Viewability helps you compare raw delivery with inventory that had a better chance of actually being seen.
CPM shows the cost to generate one thousand impressions. Lower CPM usually means cheaper volume, but it should still be reviewed with delivery quality and viewability.
Yes. When you enter a target population, the calculator estimates GRP using total gross impressions relative to that population size.
Yes. Average frequency is often a decimal because exposure counts are averaged across the reached audience. Decimals make projections more realistic.
Not always. High volume can be inefficient if repetition becomes wasteful or if viewability and conversion quality are weak. Context matters.
