Break-even analysis calculates how many units you need to sell to cover your costs. In advertising, it helps you understand if your ad spend will generate enough sales to be profitable.

Break-even units = Total Fixed Costs ÷ Profit Per Sale. Fixed costs include ad spend and monthly expenses. Profit per sale is your price minus product costs, platform fees, and payment processing fees.

Conversion rates vary by niche, price point, and traffic quality. For digital products under $50, 1-3% is common. For premium products over $100, 0.5-2% is typical. Pinterest and Instagram traffic often convert at 1-2%.

This happens when your profit per sale is zero or negative - meaning your costs and fees exceed your product price. You'll never break even because you lose money on every sale. Increase your price or reduce costs to fix this.

Profit per sale before ads is what you make after product costs, platform fees, and payment processing. Net profit per sale subtracts your ad cost per acquisition (ad spend ÷ estimated sales). This shows your true profit including advertising.

Enter your total Pinterest ad spend in the "Ad Spend" field. Pinterest typically has higher conversion rates (2-4%) than Facebook, but higher CPCs ($0.50-$2.00). Use your historical Pinterest conversion rate for accurate estimates.

Etsy: 6.5% transaction fee + payment processing + optional 15% off-site ads.
Gumroad: 10% flat fee + payment processing.
Shopify: 2.9% + $0.30 payment processing only.
Stripe: 2.9% + $0.30 payment processing.

ROI (Return on Investment) shows your profit as a percentage of your costs. Formula: (Total Revenue - Total Costs) ÷ Total Costs × 100. Positive ROI means you're making money. Negative ROI means you're losing money on ads.

1) Increase your price - Higher prices mean more profit per sale
2) Reduce costs - Lower product costs or platform fees
3) Improve conversion rate - Better listings, images, and descriptions
4) Target better keywords - More qualified traffic converts better
