Calculates a product's totals without saving anything. Use it to show a live price while a product is being created or edited.

Send the product's pricing fields. The response has the same totals block as a saved product.

• Tax is included in the price. It's taken out of the total, not added on top.
• A percentage fee or discount is calculated from the price.
• The IDs and the currency aren't checked. An unknown tax, fee or discount ID is left out of the totals.
