# Understand usage-based pricing

> Learn how usage-based pricing adapts to your store's order volume, ensuring you only pay for what you use, with flexible options for additional orders.

On the **Growth** and **Plus** plans, your monthly billing adapts to your store's order volume through usage-based billing. Each plan includes a set number of orders each month, and any orders beyond this amount incur an additional charge. Additional order rates vary by plan:

* **Growth Plan:**
  * \$199 per month, billed monthly
  * Includes **2,500 orders** per month, **\$20 per 100** additional orders.
* **Plus Plan:**
  * \$999 per month, billed yearly
  * Includes **7,500 orders** per month. **\$5 per 100** additional orders.

To learn more about how orders are counted and how to check your monthly order usage, read our [dedicated article](https://intercom.help/smile-help-center/en/articles/10131407-understand-how-orders-are-counted).

## Check your total monthly price

The easiest way to understand your total monthly price is by looking in Smile Admin. Go to **Settings** > [**Billing**](https://app.smile.io/settings/billing). You'll see a breakdown of your total cost for the previous month, as well as a preview of this month's usage and estimated total price.

## Calculate your total monthly price

If you'd like to calculate your total monthly price, you can use the following formula:

```text theme={null}
Total Price = Base Price + (Additional Orders / 100) × Rate per 100 Orders
```

* **Base Price** is the fixed cost of your plan (e.g. \$199 for Growth).
* **Additional Orders** is the number of orders exceeding your plan's included amount (e.g. 300 orders beyond 2,500).
* **Rate per 100 Orders** is the cost applied to each set of 100 additional orders, based on your plan (e.g. \$20).

## Example monthly price calculation

Imagine you're on the Growth plan and your store processes 2,800 orders in a month:

* **Base Price**: \$199 (covers the first 2,500 orders)
* **Additional Orders**: 2,800 - 2,500 = 300 orders
* **Rate per 100 Orders**: \$20

Using the formula:

**Total Monthly Price** = Base Price + (Additional Orders / 100) × Rate per 100 Orders

**Total Monthly Cost** = 199 + (300 / 100) × 20

**Total Monthly Cost** = 199 + 60 = \$259

In this scenario, your total charge for the month would be **\$259**. This usage-based pricing model allows your plan to flexibly accommodate higher order volumes without needing to upgrade immediately.

<Tip>
  **Tip:** If your orders consistently exceed **6,500**, you can save money by upgrading to the **Plus plan**, which includes more orders in the base price and has a lower rate for additional orders.
