For each event, you can charge extra for optional benefits or activities. For example, you could offer preferred seating or discounted concert tickets. The charges for these options would be in addition to the registration fee.

You can also add extra charges that are calculated using a value entered by the registrant. For example, you could add an option to purchase a specific number of items, or charge a variable event surcharge based on organization size or income.

To provide optional extras at a separate cost for an event, you add custom event fields to the event registration form. Event fields are combined with common fields from your contact database to form the event record and populate the registration form.
There are two types of extra cost fields: static fields which provide options that registrants simply choose, and calculated extra charge fields which display an input field whose value is used to calculate the actual charge.
