-:::note
-Concurrency is **not billed based on the maximum number of concurrent browsers** you hit in a single moment or day. Instead, we calculate the **daily peak concurrency**, then take the **average across the month**.

-This means if you briefly spike to 11 concurrent browsers on just one day, you won’t be charged for that full number unless your monthly average ends up over the included amount. We intentionally designed this to avoid penalizing brief spikes.

+<Details header="How is the number of concurrent browsers calculated?">
+Cloudflare calculates concurrent browsers as the **monthly average of your daily peak usage**. In other words, we record **the peak number of concurrent browsers each day** and then average those values over the month. This approach reflects your typical traffic and ensures you are not disproportionately charged for brief spikes in browser concurrency.
