# Retail Margin on MRP Column Attribute added in Data Entry Grid of Sale Bill

In the ‘**Setup Column Attributes**‘ of Sale Bill, a new column attribute has been added i.e., “**Retail Margin on MRP**“.

For calculating the Retail Margin, the **Sale Bill** of the item will be subtracted from **MRP**, then divided by MRP. The outcome will be then multiplied with 100, which will give you the **Retail Margin on MRP** value for the item.

**((MRP-Sale Bill)/MRP)\*100**

To make this work, first, you have to enable **Display Profitability in Bill** option in the **Sale Voucher Configuration** as shown in the figure below:

### Retail Margin(%)

There’s another column attribute i.e. **Retail Margin(%)** to display the percentage value of profitability. For calculating Retail Margin(%), the **Sale Rate** value will get subtracted from **Purchase Rate**. Then, it will be divided with **Sale Rate** value. The outcome will then multiply with **100**, which will give you Retail Margin(%) value for the item.

**((Sale Rate-Purchase Rate)/Sale Rate)\*100**

But first, you have to set Purchase Rate in the Sale Voucher Configuration settings.
