An online course can look profitable until small recurring charges and per-sale fees are added. The course platform is only one line in the budget. Payment processing, email marketing, video tools, domains, integrations, refunds, and customer support can change the real cost of a launch.
This tutorial is research-based and uses official pricing and fee pages reviewed on October 30, 2026. It does not claim hands-on testing. Prices, plan limits, eligibility, and processing rates can change, so confirm current terms before subscribing.

Start with five cost buckets
Create a simple worksheet before comparing platforms. Use five sections: fixed software, payment processing, platform transaction fees, launch services, and a contingency reserve. Fixed software includes the course platform, email service, domain, community tool, and any required integration. Processing and platform fees change with sales volume. Launch services include one-time purchases such as editing, design, or captions.
Keep optional upgrades out of the first version. A feature is not a launch cost unless the course needs it to collect a lead, accept payment, deliver lessons, or support students. This rule prevents an ambitious future setup from distorting the cost of validating the first offer.
Calculate monthly fixed costs
List every recurring subscription at its monthly cash price. Annual plans may have a lower equivalent monthly rate, but they require more cash upfront. Use the amount that will actually leave the business account during the launch period.
Systeme.io currently lists Free at $0, Startup at $17 per month, Webinar at $47, and Unlimited at $97 with monthly billing. Its pricing page says all plans include unlimited email and a 0% platform transaction fee. Payment processor fees still apply. Thinkific currently lists Start at $109 per month, Grow at $219, and Expand at $499 with monthly billing. A creator comparing the two should also include any external email or automation subscription needed with the selected setup.
Use this formula:
Monthly fixed cost = platform + email + domain allocation + integrations + community + other required subscriptions
Estimate payment processing correctly
Payment fees usually contain a percentage and a fixed amount per transaction. Stripe's standard US pricing currently lists 2.9% plus $0.30 for domestic online card transactions, with additional charges for international cards and currency conversion. PayPal's US business fee page, updated October 1, 2026, lists different rates by product. PayPal Checkout is 3.49% plus the fixed fee, while standard credit and debit card payments are 2.99% plus the fixed fee.
Apply the correct rate for the payment method you plan to offer:
Processor cost = (sales revenue × percentage fee) + (number of transactions × fixed fee)
A clearly labeled planning example
Assume a $99 course records 20 domestic US card sales through Stripe. Gross revenue would be $1,980. At the published standard rate, the planning estimate is $57.42 for the percentage component plus $6.00 in fixed charges, or $63.42 total. This is a hypothetical estimate, not a quote or a prediction. Taxes, refunds, disputes, international cards, currency conversion, and alternative payment methods could change the result.
Add platform and gateway fees
A platform can charge its own transaction fee in addition to the processor. Systeme.io states that its platform fee is 0%, so the worksheet still includes Stripe, PayPal, or another processor but no separate percentage from Systeme.io.
Thinkific says no additional third-party gateway fee applies when an eligible creator uses Thinkific Payments or TCommerce. Its official support page currently lists additional fees for third-party gateway transactions in the United States, Canada, the United Kingdom, and the European Union: 2% on Start, 1% on Grow, and 0.5% on Expand, while Plus has no fee at this time. Availability matters, so verify eligibility before treating that fee as zero.
Write processor fees and platform fees on separate lines. Combining them hides the reason a cost changes when the creator switches plans or payment providers.
Include costs outside the course platform
Course videos may require recording, editing, captioning, or storage. The launch may need a domain, branded email, webinar service, scheduling tool, community platform, or automation connector. Support also has a cost, even when the creator handles it personally.
Estimate labor with hours rather than pretending it is free. A basic formula is hours per month multiplied by an internal hourly value. This figure does not have to appear in accounting records to be useful. It shows whether a low-priced software stack creates expensive manual work.
Refunds and disputes deserve a separate reserve. Do not subtract an invented industry average. Use the refund policy, expected sales count, and real results after launch. Until data exists, label the reserve as an assumption.
Build three launch scenarios
Low scenario
Use the minimum platform tier, conservative sales volume, domestic payment fees, and only required tools. This scenario tests whether the course can launch without unnecessary subscriptions.
Expected scenario
Use the sales count supported by the current audience and campaign plan. Include the tools that the actual workflow needs. Avoid treating a hope as forecast evidence.
Stress scenario
Add lower sales, a few refunds, international processing where relevant, and one month of extra software. The stress case shows how much cash is needed if the launch takes longer than planned.
Compare cost per sale and break-even sales
Total monthly cost alone can be misleading. Divide variable costs by completed sales to see cost per transaction. Then calculate how many sales are needed to cover fixed costs.
Contribution per sale = course price − processor fee per sale − platform fee per sale − expected variable support cost
Break-even sales = monthly fixed cost ÷ contribution per sale
Round break-even sales up to the next whole number. Treat the result as an operating threshold, not a revenue promise.
Choose the stack after the worksheet
A creator who wants funnels, email, checkout, automation, and course delivery in one lower-cost account can review Systeme.io through this affiliate link. The Systeme.io vs Thinkific comparison explains the broader buying tradeoffs, while the step-by-step Systeme.io course guide covers course setup and delivery.
Save the worksheet and replace assumptions with actual charges after the first month. The most useful budget is not the most detailed one. It is the version that separates verified prices, explicit assumptions, and real results, making the next platform decision easier to explain.
