The same $10,000 in Udemy sales can pay you $9,700 — or just $3,700.

It depends on how the student found your course. Through your own coupon or referral link, you keep 97% and Udemy takes 3%. Through Udemy's organic marketplace, search, or ads, you keep just 37% and Udemy keeps 63%. Affiliate-driven sales pay the instructor about 25%. Most instructors earn a blend — which is exactly what the Traffic Source Mixer models.

Because most marketplace sales pay you 37%, not 97%. On $10,000 of gross sales, an all-organic mix pays roughly $3,700, while an all-instructor-coupon mix pays roughly $9,700. The calculator shows your real blended payout before you publish.

Yes. It models all four platforms with current fees — Teachable's Starter/Builder/Growth plans and transaction fees, Kajabi's tiered plans and payment rates, and Gumroad's 10% + $0.50 direct fee (and 30% marketplace). Compare net income side by side for the same course.

Gumroad charges 10% + $0.50 per transaction on direct sales, with card processing (about 2.9% + $0.30) charged separately. Discover-marketplace sales are a flat 30% that includes processing. There's no monthly fee.

It depends on how much traffic you drive yourself. If most of your Udemy sales are organic (37% to you), moving the same sales to Teachable, Kajabi, or Gumroad can sharply raise your take-home — but you'd build your own audience. The "Should I Leave Udemy?" tool shows the annual gap and your break-even timeline so the choice is financial, not emotional.

It's a one-time download with no subscription and no account. The tool runs 100% offline after the first load — your prices, sales, and portfolio never leave your device. Everything is stored locally in your browser.

Fee data was verified against each platform's official pricing and help pages on 2026-05-24. Platforms change rates over time, so always confirm current fees on each official site before deciding.

On a single $97 sale at the default 60/30/10 traffic mix, the calculator shows Udemy paying about $69.65, Teachable Builder and Kajabi Starter about $93.89 each, and Gumroad direct about $83.69. Those are per-sale figures; the 'Monthly net' line then subtracts each platform's fixed monthly fee, which is what decides the real winner.

Because Udemy pays a blended rate, while the others only deduct card processing per sale. You keep 97% on your own coupon or referral sales, just 37% on Udemy's organic, search, and ads, and about 25% on affiliate sales. The default 60/30/10 mix blends to roughly 71.8%, so a $97 sale nets about $69.65 — below Teachable's and Kajabi's $93.89. Open the 'Udemy traffic mix' box and raise your coupon share to watch that blended rate climb.

It depends on your sales volume. Teachable Builder ($89/month) and Kajabi Starter ($149/month) take almost nothing per sale, so their net per sale looks high — but the 'Monthly net' line subtracts the fixed fee. At low volume that can go negative; for example, one $97 Kajabi sale nets $93.89 - $149 = -$55.11. The more you sell, the faster those flat fees are absorbed, so raise 'Sales per Month' to find the point where they pay off.

Yes. The calculator on this page runs entirely in your browser with plain JavaScript — no network requests, no accounts, no cookies, and nothing is tracked about what you type. Your price, sales, and traffic-mix values never leave your device. The paid full version is a single offline HTML file that works the same way, with far more detail.
