# Donation Types
### **Donation Type Actor**
Is the entity that will be monetarily responsible for the donation. There are three actor values to choose from based on the merchant’s preference:
* **Merchant**: The merchant is solely responsible for funding the donation.
* **Customer**: The customer is solely responsible for funding the donation.
* **Merchant/Customer Match**: The merchant will match the donation amount of the customer, and both are responsible for funding their donation amount.
Who makes the donation controls.
### **Donation Type Option**
The donation type option is the method used to calculate the monetary donation amount. There are three options available for the merchant to choose from:
* **Fixed**: A fixed donation amount can be set within the Fixed Amount input.
* **Percentage**: The *donation amount will be calculated as a percentage of the adjusted merchandise total (subtotal)*. The percent amount can be set within the ***Enter Percentage*** input.
* **Round-up**: The donation amount will be calculated as a round-up of the monetary value to the right of the decimal point (i.e., USD: cents). This *round-up is calculated using the order total* and will always cause the order total to calculate to a whole monetary value (e.g., $39.49 will round to $40.00 and the donation amount would calculate to $0.51).
