Online Course Profit Calculator

Selling an online course can generate significant passive income once the course is created and the marketing funnel is in place. But upfront costs - production, platform fees, email software, and advertising - mean it takes time to recoup your investment and reach real profitability. This online course profit calculator helps you model a course launch or ongoing evergreen sales. Enter your course price, expected student enrolments per month, platform fee rate, payment processing rate, monthly platform subscription cost, creation costs (one-off), and monthly marketing spend. The calculator shows gross revenue, total costs, net profit, and the number of months to recoup your creation investment.

Course profit formula

Gross Revenue = Course Price x Students x (1 - Refund Rate / 100)
Platform Fee = Gross Revenue x Platform Fee% / 100
Payment Fee = Gross Revenue x Payment% / 100
Monthly Costs = Platform Fee + Payment Fee + Platform Subscription + Marketing
Net Monthly Profit = Gross Revenue - Monthly Costs
Months to Recoup = Creation Cost / Net Monthly Profit

Frequently asked questions

How much can you earn from an online course?

Online course earnings vary enormously. Niche courses with small but targeted audiences can earn $5,000-50,000 per year. Courses in large popular markets (business, marketing, technology) can earn $100,000+ per year. The key factors are audience size, email list size, course price, conversion rate on launches, and whether you use evergreen funnels or periodic launches.

What platform fees do course creators pay?

Platform fees vary: Teachable charges 0% on Pro plans ($119/month) but 5% on its free plan. Thinkific has a free plan with no transaction fees. Kajabi charges no transaction fees on its paid plans. Udemy takes 50% of revenue when Udemy markets your course (37% when students use a coupon you provided). Selling on your own website via Stripe or PayPal costs only payment processing (2.9% + $0.30).

What costs go into creating an online course?

Course creation costs include: course platform subscription, video recording equipment and software (Camtasia, ScreenFlow), graphic design for slides and thumbnails, course materials and workbooks, copywriting or editing help, email marketing platform, advertising for initial launch, and your time (which should be valued at a meaningful hourly rate). Many solo creators spend $500-5,000 creating a first course.

What is a good conversion rate for an online course launch?

Email list conversion rates for online course launches typically run 1-5% for warm audiences. If you have 5,000 email subscribers and launch a $297 course, a 2% conversion rate yields 100 sales and $29,700 gross revenue. Webinar-based launches often convert at 3-10% of webinar attendees. Paid advertising to cold traffic converts much lower, often 0.5-1%.

Should I price my course low to get more students?

Lower prices attract more students but may signal lower quality. A well-crafted course priced at $200-500 often earns more total revenue than the same course priced at $47, because higher prices generate higher perceived value, fewer refunds, and a smaller but more motivated student base. Research competitor courses in your niche before setting your price.
