Method
Gross = Price × (1 − Discount) × Sales; Net = Gross × (1 − Refund rate) × (1 − Fee rate); Profit = Net − Fixed; Break-even = ⌈Fixed ÷ Net per enrolment⌉
- Fee rate
- platform share plus payment processing, as a % of money kept after refunds
- Fixed
- production, equipment and marketing costs that do not depend on sales
Worked example
- Gross = 100 × 0.80 × 500 = 40,000.
- After 5% refunds: 38,000; after 10% fees: 34,200 net.
- Net per enrolment = 80 × 0.95 × 0.90 = 68.40, so 10,000 ÷ 68.40 → 147 sales to break even.
500 sales at 100 list bring in 34,200 net and 24,200 profit after 10,000 of production costs; break-even is 147 sales.
What the result means
Net per enrolment is the number to watch when you change price or run discounts: a deep discount needs proportionally more sales to earn the same.
Assumptions and limits
- Fees are charged on money kept after refunds.
- Discount and refund rates are averages across all sales.
- Taxes such as VAT or sales tax and affiliate commissions are not included; add them to the fee rate if they apply.
Questions
Why does the discount matter so much?
Fees and refunds are percentages, so they shrink with price, but your fixed costs do not.
Where do I find the platform fee?
In your platform’s pricing or revenue-share terms. Many have different shares for organic and marketplace sales, so use a blended figure.
