How can I create a pricing formula per quantity for my order form?

I want to create a formula for my order form. For example I want my jars to be $6 ea. but if they purchase 4 or more I want it to be $5 each. How I would go about doing that on the form and have them pay for it at the same time.

Thank you

It appears you have already found the Special Pricing Per Quantity option within the payment field.

More advanced calculations including conditional calculations can be implemented only with the regular fields.
