Online tutoring is approachable: an undergraduate background in a subject plus some communication experience is usually enough to teach high-school SAT prep or basic college-level writing. The hard part is rarely the teaching. It is figuring out which platform is actually worth the time once the platform takes its cut. To make the comparison concrete, the example below assumes a tutor covering two subjects across eight platforms.
Subjects and students, as an example
Two subjects: SAT maths preparation and undergraduate-level essay writing. The typical students are high school juniors and seniors and early-stage college students. A typical session runs 50 minutes, weekly, at $35–$95 depending on platform and direct vs. marketplace.
The eight platforms compared here are Wyzant, Preply, Varsity Tutors, Cambly, Tutor.com, Italki, Outschool, and Superprof. The figures below reflect earnings, hours billed, unbilled prep, and platform fees — the kind of comparison any tutor can reconstruct from each platform's published fee schedule.
The platforms, ranked by effective pay
Effective hourly rate, after platform fees and an estimate of unbilled prep time per session.
| Platform | Listed rate | Platform fee | Effective $/hour to me |
|---|---|---|---|
| Wyzant | $45/hr | 25% (sliding) | $28 |
| Preply | $28/hr | 18–33% | $17 |
| Varsity Tutors | (set by them) | ~50% | $22 |
| Cambly | $0.17/min | none | $10 |
| Tutor.com | $10–$20/hr | none | $14 |
| Italki | $22/hr | 15% | $18 |
| Outschool | $60/class | 30% | $26 |
| Superprof | $50/hr | subscription model (free for me to keep, paid by student) | $38 |
The headline rates are all over the place; the after-fee rates are also all over the place, but in a different order. Cambly's "$0.17 per minute" sounds like $10.20/hour, which is what it is. Wyzant's "$45/hour" becomes $28 after the platform's 25% cut. Superprof uses a subscription model in which the student pays Superprof a one-time fee for access; the tutor pays no platform cut on lessons and can even move students fully off-platform after the first session, which makes the effective rate the highest of the eight.
Why direct tutoring beats every platform
Effective rates do rise modestly with time on a platform — better reviews on Wyzant unlock higher listed rates, Superprof connections convert to direct clients — but the ceiling is the platform itself. The same hour of teaching, with the same student, pays 30–50% more when billed directly (via a tool like Stripe) instead of through the platform.
Most platforms' terms of service prohibit moving students off-platform during the contract period, and some prohibit it indefinitely. Read the specific terms before doing this. Superprof's model explicitly permits it after the first session; Wyzant and Preply prohibit it; Italki technically prohibits it but enforcement appears minimal.
The workable pattern: use a platform to acquire a student, then — after the first month, if the student is a fit and the terms allow it — offer a small direct-billing rate ($55/hour vs. $70 on the platform) that benefits both sides. The platform's incentive structure makes this tension inevitable.
Tutoring platforms are customer-acquisition channels, not employers. Treat them as such, and the math becomes more workable.
A system that works
A practical setup keeps two platforms active — for example Wyzant for SAT students and Superprof for college writing students. The acquisition flow: take new students through the platform, see how they fit, and after about a month give them the option to continue on a direct-billed monthly retainer where the terms of service permit it. Roughly 40% tend to take the offer.
At 8–10 hours of paid tutoring a week, mostly evenings and weekends, a blended effective rate around $42/hour works out to roughly $12,400 a year. That is real money, but tutoring is a topped-out side income — it does not scale the way project-based freelance work can. Note too that tutoring income is self-employment income; the reporting obligations are covered at the IRS Gig Economy Tax Center.
Advice if you are starting
- Avoid the lowest-rate platforms entirely. Cambly, Tutor.com, and most "global" platforms targeting non-native English speakers pay $10–$15/hour by design. There is no skill ladder there.
- Optimize for review-driven rate increases on one platform. Wyzant in particular rewards strong reviews with higher listed rates. Focus on excellent first sessions, ask for honest reviews from students who clearly benefited, and push your listed rate up over the first six months.
- Read the off-platform terms. Some platforms strictly prohibit moving students. Others, like Superprof, do not. The economics of tutoring at scale are determined by this single clause more than by any other variable.
- Specialize. "I tutor everything" is unprofessional. "I tutor SAT maths, exclusively, and have a 95th-percentile score myself" books more sessions at a higher rate. Same advice as freelance writing, applied to teaching.
If you are good at one thing and can teach it patiently, tutoring is a more durable side hustle than most. It does not scale. It does, however, pay reliably, every week, for as long as you want to keep teaching.
