Empty price placeholder design

Question

I have a checkout form for a payment request, in which the user fills in the payment amount. This amount is used as input for the checkout as a sub-total, of which a percentage is deducted.

What is the best practice for placeholders in checkout prices? In other words, what should I put in place of "N/A" in the price table before the user enters a number?

N/A vs. €0 vs. ??

Answer 1

Defaulting everything to 0 is fine. If they have not defined a "requested amount" then the amount requested is 0, and so are all the other numbers.

Answer 2

I would avoid using N/A, as that signifies that field is "not applicable". All three of those fields are applicable.

A simple placeholder would be:

€ 0,0

For every field needed.

Answer 3

Try hiding the entire confirmation section until the requested amount is entered.
