# Usage
> Track interview volume, your included allowance, and overage costs.
The **Usage** tab shows how many interviews your organization has collected, how that compares to your allowance, and what you've spent.
## Open the Usage tab
1. Click **Organization** in the sidebar.
2. Go to the **Usage** tab.
## During your free trial
While you're on the free trial, the top of the tab shows your trial allowance:
* **Engaged conversations**: how many trial interviews you've used
* **Remaining in trial**: how many you have left
* **Trial progress**: a bar showing usage against your trial limit
Only **live, engaged conversations** count toward the trial. Test interviews never count.
When you reach your trial limit, the tab shows **Free trial ended**. Upgrade on the [Billing](/account/billing) tab to keep collecting interviews.
## On a paid plan
Once you're on a plan, the tab shows your **current billing period**:
* **Total interviews**: interviews collected this period
* **Included allowance**: a progress bar against the interviews included in your plan, with the date your allowance **renews**
* **Overage interviews**: interviews beyond your included allowance
* **Overage cost**: what those extra interviews cost at your plan's overage rate
## What counts as a billed interview
A billed interview is a **live** interview with at least **two participant answers**. Short or abandoned interviews and all test interviews are never billed.
## Daily and per-study breakdown
Below the summary, two charts help you spot trends:
* **Daily breakdown**: interviews per day across the period you pick (last 7 days, last month, last 3 months, or last 6 months)
* **By campaign**: interviews broken down by study
