Your one-time prize payment depends on the prize structure for the challenge you entered. You can find the prize structure for each challenge on the challenge page (go to www.minted.com/contest, then click "Submit a Design" for the specific challenge), in the Challenge Kit available for download on the challenge page, and in our winner's emails to the whole community. You will receive the amount that corresponds to your win (for example 1st place vs. Editors' Pick).
Winners also receive ongoing commission payments on the sales of all winning designs once they've been launched to our site.
Commission payments are calculated based on ‘Commissionable Net Sales after Adjustments & Discounts’. This is defined as the total net sales amount after subtracting all promotional discounts and any adjustments due to refunds/returns.
You can see more information on sales commissions here.
