# How to check how many credits your account is using
> Understand what counts as a credit in Eva, review consumption by period, and find out which agent spends the most before it surprises you.
Eva measures the work your agents do in credits. The **Usage** screen tells you how many you have
used, how they were spread over time, and which agent consumed the most. It is in **Settings**, on
the **Usage** tab.
## What you will get
You will be able to answer, with numbers, how much each agent is working and where your account's
credits are going.
## Requirements
* The **Advanced Settings** module turned on. The **Usage** tab appears only for whoever has it.
* At least one agent that has already held a conversation, so there is something to show.
## What counts as a credit
A credit is not a customer message and not a conversation. It is charged for the work the AI does.
| What happens | Credits |
| ------------------------------------ | -------------------------------------- |
| Your agent replies in a conversation | 1 per reply |
| Your agent sends a follow-up | 1 |
| A WhatsApp campaign is sent | 1 per 10 successful sends |
| A campaign send fails | 0 |
| An email campaign is sent | 0 |
| A voice call in Eva | 3 per minute, rounded up |
| A WhatsApp call your agent makes | 1 per minute, rounded up |
| Your agent generates an image | Depends on the size and quality chosen |
| Your agent reads a quotation PDF | 1 |
WhatsApp campaigns count only the sends that actually went out, and round up: 25 successful sends
consume 3 credits. Failed recipients are never charged.
## What the screen shows
At the top there are four cards summarizing the chosen period:
* **Total credits** — the period total. With an active subscription it also indicates how much of
the credit allowance included in your plan you have used, and the dates of that billing period.
If you bought credits, it also shows **Purchased credits available**: what you have left of them.
Plan credits renew each month and do not carry over; purchased credits never expire and are used
after your plan credits.
* **Active agents** — how many of your agents had any consumption.
* **Daily average** — credits per day in that range.
* **Top agent** — the agent that consumed the most.
**View breakdown** opens the detail by type of consumption: **Campaigns** on one side and
**Other** for everything else, agent replies included. Further down, **Usage over time** charts
consumption day by day. **Credits by Agent** breaks it into a table with the **% of Total**.
## Change the period or filter by agent
In the period selector, choose **Last 7 days**, **Last 30 days**, or **Custom range**. When
you pick your own range, the header shows the exact dates of the period.
Under **All AI agents**, check the agents you want to compare and select **Apply**.
Under **Credits by Agent**, select **Export CSV** if you want to work with them elsewhere.
If one agent sits far above the rest in **Credits by Agent**, review its conversation volume and
its automatic follow-ups. The explanation is usually there.
## How to know it worked
When you change the period, the four cards and the chart refresh with the new range. If the period
has any consumption, **Credits by Agent** shows at least one row.
## If something goes wrong
That tab appears for whoever has the **Advanced Settings** module. The **Sales Rep** role does
not have it turned on by default.
The chosen range has no consumption. Widen the period to **Last 30 days** or remove the agent
filter.
WhatsApp campaigns are charged 1 credit per 10 successful sends, not one per recipient. Failed
sends are not charged.
The table groups them under **Other / no agent**. These are consumptions that were not
attributed to a particular agent.
