Online calculus classes split into two products: a real taught course, or metered homework help sold by the hour.

Art of Problem Solving (incl. Beast Academy)
Online calculus classes are bought as a course, not as tutoring by the hour, and Art of Problem Solving is the only provider here selling one properly. The AoPS 25-week Calculus class is approved by the College Board as an AP Calculus BC class and covers limits, continuity, derivatives and applications, definite and indefinite integrals, infinite sequences and series, plane curves, polar coordinates and basic differential equations. AoPS publishes a price of $835, about $33.40 per lesson and $16.70 per class-hour, which undercuts almost any 1-on-1 on this list. AoPS homework includes writing problems that get personalised written feedback rather than auto-graded answers.
Sorted by price per hour, cheapest first. Sessions run from 22 to 120 minutes, so the hourly figure is the only like-for-like comparison.

One real limitation
It is not available to younger children and is not taught by professional teachers: the terms require "You confirm that you are 13 years of age or older" and tutors are unpaid student volunteers — "Our tutors are high school students just like you" — certified only by passing Khan Academy unit tests. Series are also tutor-dependent and can vanish; one observed math series shows "cancelled by the tutor".
AoPS Online School classes are conducted in a "text-and-image-based" classroom — students read and type in a live chat-style room rather than seeing or hearing a teacher on video — which is a poor fit for younger students, slow typists, or kids who need spoken explanation. AoPS also publishes no maximum class size on its online-school pages.
The advertised $15/class floor is only available on the 12-month commitment (104 classes, billed as a "$1560 coaching fee, billed every 52 weeks"); the 6-month plan raises the same tier to $17/class and adds a "$90 platform fee per billing cycle" that the 12-month plan waives.
The heavily advertised "$17.70/lesson" headline — used in page titles across their whole site — is not a general rate: the pricing page shows it requires the 12-month plan AND states "All prices apply to packages of 2 lessons per week". A 1-month term costs $21.90/lesson, roughly 24% more.
Sessions are only "50 to 55 minutes of teaching time", and prepaid packs expire on a fixed clock — the 10-session pack must be used within 3 months and the 50-session pack within 6 months, so unused sessions are forfeited.
The advertised $29-$40/hr rates buy on-demand drop-in help from whichever tutor happens to be available, not a consistent teacher who knows the child — a dedicated tutor requires the Comprehensive Tutoring product, whose hourly packages start at "$80/hr", roughly double.
The advertised $56 is the bottom of a $56–$99 per-session band, and Learner's own site says rates “vary based on the tutor's experience and level of education, as well as the tutoring package” — so the figure you are quoted may be nearly double. The trial is not free either: it costs $25.
K12 Tutoring does not serve grades K-3 at all — their about page states coverage of "grades 4-12", so families of kindergarten through third-grade children cannot use it.
There is no low-cost group option for math: their only group product is test prep ("up to 10 students ... Grades 9-12 ... starting at $499"), so every math subject from elementary through AP Calculus is sold exclusively as 1-on-1 packages with a 12-hour minimum entry buy of $948.
There are no live class meetings at all — their FAQ states "Courses are designed to be asynchronous", so a student who needs a teacher to explain a derivative in real time gets written or recorded feedback on a weekly cycle instead.
Because every tutor sets their own price, the advertised average is close to meaningless for budgeting: their own Elementary Math page says "$30 - 50 per hour on average" while the tutors actually listed on that same page charge $40, $75, $120, $200, $250, $320 and $349 per hour — roughly an 8x spread against a band topping out at $50.
We verified pricing, trial availability and session length directly from each provider's own pages in September 2026, and re-check quarterly. Prices are normalized to an hourly rate using the provider's own stated session length; where a provider does not publish pricing, we say so rather than estimating.
