Frequently asked questions

What does the Impressions from reach and frequency actually compute?

It takes Unique reach (people) and Average frequency and derives Total impressions from them. The calculation is live as you type, so the result updates on every change.

What information do I need to provide?

2 values: Unique reach (people) and Average frequency. Nothing else is required — no account, no file upload.

Can you show a worked example?

With Unique reach (people) = 10,000 and Average frequency = 3, the calculator returns Total impressions = 30,000. Those figures come from running this exact tool, so you can reproduce them by entering the same values.

What happens if I enter larger values?

It moves a lot. Using Unique reach (people) = 20,000 and Average frequency = 6 instead, Total impressions goes from 30,000 to 120,000 — which is why it is worth testing a few scenarios rather than trusting a single figure.

What does it give for smaller values?

Scaled down to Unique reach (people) = 5,000 and Average frequency = 1.5, Total impressions comes out at 7,500. The relationship is worth checking at both ends before you rely on a single result.

When would I actually use this?

Before and after a campaign: turning a target into a daily budget, comparing two channels on the same basis, and deciding whether the return justifies continuing.

What is the most common mistake?

Judging ROAS without subtracting the cost of goods. A 3× return on ad spend is a loss whenever the margin is under a third — the ratio says nothing about profit on its own.

What is the difference between the Impressions from reach and frequency and the ARPU calculator?

This one returns Total impressions; the ARPU calculator returns Average revenue per user. That is the whole difference — open the one whose figure you need.

Is there a tool for the next step?

Average order value (AOV) calculator is the closest one after this: Compute your average order value from total revenue and number of orders.

What else is worth having open alongside it?

Ad Cost Calculator (CPM, CPC, CPA, CTR) and CPM calculator — they come up in the same task often enough to be worth a second tab.
