Price and discount
Applied to the price after the first discount, not the original price — that's how stacked discounts actually work.

Markup vs. margin — a quick word
Stacking discounts is the most common way people misjudge a sale price: two 20% discounts feel like "40% off," but the second 20% is taken from a smaller number, so the true saving is 36%. If you want the reverse question answered — "what markup gets me to this sell price?" — see the markup calculator.

What this page cannot do
The discount matters after you have given it.
A sale price is easy to work out and easy to forget. What is harder is remembering, three months later, which client got which discount and what it cost you. Ochre has the same calculator inside the invoice, writing into the document’s totals — so the discount becomes part of the record rather than a number you did in your head.
