## Monthly Limit (Budget)

Each organization has a **monthly spending limit** (budget). This is the maximum amount you can spend on API usage within a calendar month.

Once your spending reaches the budget limit, API requests will be blocked until:

* The next billing period begins (1st of the following month), or
* You increase the limit in the [Dashboard](https://dashboard.prem.io/billing)

<Info>
  Your monthly spending (`period_spent`) resets to zero on the **1st of each month** automatically.
</Info>

## Why change your limit?

* **Cost protection** — prevent unexpected charges from runaway scripts or misconfigured integrations
* **Team budget control** — keep spending within your organization's allocated budget
* **Scaling up** — increase the limit as your usage grows

## Default limits by tier

Each [usage tier](/developer-resources/get-started/rate-limits#usage-tiers) comes with a default monthly budget limit:

| Tier   | Monthly Budget Limit |
| ------ | -------------------- |
| Base   | \$100                |
| Tier 1 | \$500                |
| Tier 2 | \$5,000              |
| Tier 3 | \$20,000             |

<Tip>
  You can adjust your monthly limit at any time through the Dashboard. Increasing the limit takes effect immediately.
