# Metric Expression for Single Value Card

> This guide is essential to enhance dashboards by leveraging Metric Expressions for single-value cards.

> Metric Expressions allow you to perform calculations using single-value card metrics by referencing their values with their **Metric IDs**.

> **Example:**

> We have two single value cards:
>
> * Sales with Metric ID `{{Sales_hwPED}}`, valued at **\$2.89B**
> * Profit with Metric ID `{{Profi_qjvSWB}}`, valued at **\$2.84B**

> To calculate the Sales Profitability Ratio, we can use a Metric Expression:
>
> * `ROUND({{Sales_hwPED}}/{{Profi_qjvSWB}}, 2)`\
>   Output: A single-value card displaying **1.02**

> Alternatively using,\
> `{{Sales_hwPED}}` / `{{Profi_qjvSWB}}`\
> Output: A single-value card displaying\
> **2891075848.0202847 / 2840122818.152845**

### 2. **Configure Metric Expression**

* Enter your suitable title and description for the metric expression.
* Choose the Element Type as **"Metric Expression"**.
* Select the metrics you want to include in the computation.
* In the **"Metric Expression"** text box, write the formula to be applied to the chosen single-value cards.
  > Reference the value of a single-value card using its **Metric ID** like `{{metricid}}`
* Customize the appearance of the single-value card using font options such as **font family**, **font size**, and **font weight**.
* (Optional) Enable **"Merge Card to Background"** if you want to blend the metric into the dashboard background.
* Click **"Save"** to complete the setup.
