How this calculator works
The calculator starts with gross revenue by multiplying unit sales by selling price. Refunds are subtracted as a percentage of gross revenue, reflecting the reality that digital products typically see 1-5% refund rates. Platform fees — such as Gumroad's 10%, Etsy's 6.5%, or course platform fees of 5-15% — are deducted next as variable costs per sale. Fixed production costs (design, tools, your own labor at a reasonable hourly rate) and marketing costs are then subtracted to arrive at net profit. Profit margin is calculated as net profit divided by gross revenue, and break-even sales volume is determined by dividing total fixed costs by the profit contribution per unit after variable costs.
Useful scenarios
- A creator validating whether a $27 Notion template pack with 200 expected sales can justify $500 in production time and design costs plus $200 in launch marketing.
- A course seller estimating profit on a $197 course with 150 enrollments, 3% refund rate, 10% platform fee, $2,000 production cost, and $1,500 in ad spend.
- A freelancer packaging reusable client templates into a $47 digital product, estimating 100 sales at 2% refunds, 10% Gumroad fee, and $800 in production time.
FAQ
Should I include my own time as a cost?
For a stricter model, convert your production hours into a dollar cost and add it to fixed production costs.
Why does break-even matter?
Break-even sales show the minimum volume needed before the product pays back its fixed and marketing costs.
How do I know if my digital product is priced correctly?
Look at your profit margin after all costs. For digital products, a 50-70% net margin is a healthy target. If your margin is below 30%, your price is likely too low, your platform fees are too high, or your marketing cost per sale is eating too much profit. Consider raising prices or switching to a lower-fee platform.
