# Set Commission Calculation Settings
**GoAffPro** provides you with the option to set the commission calculation settings for affiliates.
To set the commission calculation settings for affiliates, go to the **General** section in the **Settings** tab of the GoAffPro admin panel.
Settings > General
Now, go to the Sales section.
### Include discounts
Enable the "**Include discounts**" option. You can adjust the commission calculation by the discount percentage, the discount amount, or a custom percentage. Also, you can create exceptions for coupon codes assigned to affiliates.
Additionally, you can enable the "**Also adjust for automatic store discounts**" option, which would adjust the commissions for automatic store discounts.

When the "Include discounts" option is enabled, the commission will be calculated based on the discounted product price rather than the full order amount.
For example, if a customer spends $100 in the store using an affiliate's referral, applies a 10% discount, and the commission rate is 20%, the commission will be calculated on the discounted product price. In this case, the calculation would be: $100 - $10 = $90, and the affiliate's commission would be 20% of $90, which equals $18.

### Exclude shipping and taxes
Enable the "**Exclude shipping and taxes**" option. It can be used to exclude the shipping fee from the commission calculation.
### Exclude VAT
Enable the "**Exclude VAT**" option. You also have the option to include the VAT in shipping. It is used to deduct the VAT from the product price before calculating the commission on the order.
