## Financial Formulas

### Net Profit Formula (Etsy):
Net Profit = (Selling Price + Shipping Charged) - (Listing Fee + Transaction Fee + Processing Fee + Offsite Ads) - (Product Cost + Packaging Cost + Seller Shipping Cost + Ad Spend)

### Profit Margin %:
Profit Margin % = (Net Profit / Gross Revenue) * 100

### Markup %:
Markup % = (Net Profit / Cost of Goods Sold) * 100

### Break-Even Price Formula:
Break-Even Price = (Fixed Overhead + Variable Unit Costs + Fixed Per-Transaction Fees) / (1 - Variable Fee Rate %)
