Kumon vs Mathnasium vs Thinkster (2026): format, cost and how each one works
On this page
Kumon, Mathnasium and Thinkster are the three names parents most often weigh against each other when a child needs more math, and most of the comparisons that answer that search are written by one of the companies being compared. Thinkster publishes its own "Kumon vs Mathnasium vs Thinkster" article, and Brighterly, a rival tutoring company, publishes a Mathnasium vs Kumon one. There is nothing improper in a company explaining its product, but it is not a neutral reading. This page is: no company here paid to be included, there are no affiliate links, and every price was read on each vendor's own site on 4 October 2026. Where a vendor does not publish a price, we say so instead of borrowing someone else's estimate.
- Only Thinkster publishes a price. Its Ignite plan starts at $22.50 per 45-minute session and its Signature plan at $45 per session. Kumon and Mathnasium are franchise networks; both say pricing is set locally and both send you to a center.
- They are three different methods, not three versions of one product. Kumon is daily worksheets in math and reading. Mathnasium is math-only instruction from a personalised plan, in a center or online. Thinkster is an online weekly tutor plus an AI practice coach.
- Online vs in-center: Thinkster is online only. Mathnasium offers both and lets students switch. Kumon is center-based, with a digital worksheet platform (Kumon Connect).
- Ages: Kumon serves ages 3 and up, including teens. Mathnasium serves K-12. Thinkster covers K-8 plus Algebra 1 and Geometry.
- We make no claim about results. Each vendor publishes its own satisfaction or improvement figures; none of them is an independent study, and none predicts what your child will do.
Kumon vs Mathnasium vs Thinkster: the three side by side
The table compares what each vendor states on its own site. The last two rows are the institutional layer: who delivers the teaching, which matters for state ESA tutoring rules, and whether accreditation applies at all.
| Factor | Kumon | Mathnasium | Thinkster |
|---|---|---|---|
| Subjects | Math and reading | Math only (plus SAT and ACT math prep) | Math only |
| Ages or grades | Ages 3-5, 6-12 and 13+ | K-12; online group sessions for ages 4 to 6 | K-8, Algebra 1 and Geometry |
| Format | Self-learning worksheets; most students attend a center twice a week | Instruction in a center or live online (Mathnasium@home); switch between the two | Online only: live 1:1 sessions plus a 24/7 AI practice coach |
| Session length | Assignments designed to take under 30 minutes per subject per day | Not stated on the pages we read; set with the local center | 45 minutes, 1 to 3 sessions a week |
| Price (read 4 Oct 2026) | Not published. Monthly tuition per subject, varies by location (Kumon FAQ) | Not published. Set by each local center (find a center) | From $22.50/session (Ignite); from $45/session (Signature); monthly, quarterly or annual billing |
| How a child is assessed | Free assessment at a center before enrolment | Diagnostic skills assessment, then a personalised learning plan | Math Health Report in a 7-day free trial, then a skill-by-skill mastery map |
| Who teaches (vendor-stated) | Staff at an independently franchised Kumon Center | "Trained Mathnasium instructors" at franchised centers | A dedicated "certified" tutor (Ignite) or "masters-certified" expert tutor (Signature) |
| Accreditation | Not applicable. These are tutoring and enrichment services, not schools or curricula of record; none issues grades or transcripts that count as school credit. | ||
Read on 4 October 2026 on kumon.com, mathnasium.com and hellothinkster.com. Franchise prices vary by location. Thinkster says you select your child's level to see the price for that grade band, so "from" is the published floor, not the price for every grade.
How each one prices, and what you can and cannot compare
The single most useful fact about this comparison is structural: two of the three do not publish a price at all. That is not secrecy for its own sake. Kumon and Mathnasium are franchise systems, so each center sets its own tuition. It does mean that any national "Kumon costs $X a month" figure you read is either one center's price or a third party's estimate.
Kumon answers the question directly in its FAQ: "Kumon tuition varies by location, with a monthly tuition fee typically charged per subject. Families should contact their local Kumon Center for specific pricing." Two things follow. Enrolling in both math and reading roughly means paying two subject fees, and the number can differ between two centers in the same city. Kumon's homepage was running a promotion when we checked (gift cards of up to $100 for enrolments between 1 September and 31 October 2026, with details at each center).
Mathnasium publishes no price on its national site. Its getting-started steps are to find a location, schedule a diagnostic assessment, and book sessions with the local center director. With more than 1,100 locations, the price you are quoted is the price of that center.
Thinkster publishes per-session floors. Ignite starts at $22.50 per session and Signature at $45 per session, with plans of 1, 2 or 3 sessions a week and monthly, quarterly or annual billing. As a rough guide, which is our arithmetic and not a Thinkster quote, one Ignite session a week at the starting rate works out to about $97.50 a month (52 weeks divided by 12), and three a week to about $292.50. Thinkster frames the session price as one part of a "system" that also includes an AI coach and a parent dashboard.
Brighterly's $17.70 is its 12-month plan rate for packages of two 45-minute lessons a week; shorter plans cost more per lesson. Thinkster's figures are "starting from" prices for 45-minute sessions. The two franchise networks publish no national price, so they have no bar rather than an estimated one.
Five questions to ask before you sign anything
Because two of the three price locally, the comparison you can actually make is the one you build from written quotes. These questions turn a sales conversation into comparable numbers:
- What is the total monthly cost for my child, per subject? For Kumon, ask for math and reading separately. For Mathnasium, ask how many visits a week the quote assumes.
- Are there one-time fees? Ask about registration, assessment and materials fees, and whether the first assessment is free (Kumon advertises a free assessment; Thinkster's trial is free for 7 days).
- What is the minimum commitment, and how do I cancel or pause? Thinkster lists monthly, quarterly and annual billing and says you can pause; Brighterly's lowest per-lesson price requires a 12-month plan.
- Who will teach my child, and will it be the same person each time? Thinkster says the same tutor every session; at a center, ask how instructors are assigned.
- Can I pay with an ESA or an employer benefit? Ask the provider which programme marketplaces it is approved on, then check that marketplace yourself.
How each one assesses a child
All three start with an assessment, and all three use it to place a child rather than to grade them. The difference is what happens afterwards.
- Kumon places a child on its worksheet sequence after a free assessment at a center. The method is daily practice: its FAQ says students complete assignments daily, each typically under 30 minutes per subject, and most attend their center twice a week for guidance. Kumon describes itself as a "self-learning program" and says many students study above grade level; that is the vendor's description of the method, not a prediction for any child.
- Mathnasium runs a diagnostic skills assessment and builds a personalised learning plan from it. Its FAQ says it does "not follow pre-set curricula"; instruction follows the plan, using its own Mathnasium Method. Students can also upload school assignments and work through them with an instructor.
- Thinkster starts with a 7-day free trial that includes a "Math Health Report" and a live 30-minute session, then tracks progress on a skill-by-skill mastery map visible on a parent dashboard. Between weekly sessions, an AI coach offers practice and homework prompts.
Each company also publishes figures about results: Mathnasium cites parent survey percentages, and Thinkster offers a money-back guarantee if a child does not show "measurable improvement" after six months of consistent engagement, with conditions; its FAQ ties the performance-backed version to the Signature plan. We report these as vendor statements. We have not tested them, and we do not repeat them as findings. Read any guarantee's conditions on the vendor's own page before relying on it.
In-center vs online: what the logistics really mean
For many families the deciding factor is not method or price but the drive. A center-based programme means two trips a week at fixed hours; an online one means a quiet room and a working device.
Kumon is the most center-anchored. The worksheets are done at home daily, and Kumon Connect lets students complete them digitally, but the programme is organised around a local center and its visits. Mathnasium is the most flexible of the three on this axis: Mathnasium@home delivers live, face-to-face online sessions, and the company says students can "switch seamlessly between in-center and online learning." You still enrol through a local center, even for online sessions. Thinkster is online only, with a fixed weekly session time and the AI practice in between.
A practical test: if you cannot reliably make two weekday trips at the same times, Kumon's model will be hard to sustain, and the choice narrows to Mathnasium@home, Thinkster or one of the online alternatives below.
Credentials and ESA rules: the institutional layer
Tutoring is not accredited in the way schools are, so the institutional question for a parent is a different one: who is teaching, and will a state programme pay for it? The two are linked.
Texas is the clearest example. Under the enrolled SB 2, Texas Education Freedom Accounts list private tutoring as an allowed expense, require tutors to hold an educator credential or a relevant licence, require background checks, and require providers to be located in Texas or to be vendors registered to do business there. Homeschooled students in Texas receive a $2,000 tier for 2026-27; private school students receive $10,474. Other states set their own rules, and the provider must be approved on that state's marketplace.
That is why the table records who delivers the teaching as each vendor describes it. Kumon and Mathnasium centers are independently owned franchises, so approval, if any, is typically per center. Thinkster describes "certified" and "masters-certified" tutors. Varsity Tutors states that the experts on its platform are independent contractors. None of these descriptions is an ESA approval; your programme's marketplace is the only authority on which providers it pays. This is general information, not legal advice.
Alternatives: Varsity Tutors, Brighterly and Outschool
If none of the three fits, these are the alternatives parents most often compare them with. Prices were read on each vendor's own site on 4 October 2026.
| Provider | Format | Ages or grades | Price (read 4 Oct 2026) | Who teaches (vendor-stated) |
|---|---|---|---|---|
| Varsity Tutors | 1:1 tutoring, live classes, test prep, all subjects | K-5 through graduate | Not published; the site directs you to talk to its team about "options, availability, and pricing" | Independent contractors on the platform |
| Brighterly | 1:1 online math and reading lessons, 45 minutes | Grade 1 to high school (its own math and reading tutor pages) | From $17.70/lesson (12-month plan) to $21.90 (1-month plan), for packages of 2 lessons a week | Brighterly tutors (credentials not itemised on the pricing page) |
| Outschool | Marketplace of live small-group online classes | Ages 3 to 18 | Set by each teacher; homepage listings on 4 Oct 2026 ranged from $12 to $34 per class | Independent teachers; Outschool cites an average 5:1 student-teacher ratio |
Varsity Tutors is the broadest of the three, covering every school subject and test prep, but like Kumon and Mathnasium it does not publish a price; you are routed to a conversation. Brighterly publishes the clearest per-lesson pricing in this whole comparison: two 45-minute lessons a week, from $21.90 a lesson on a one-month plan down to $17.70 on a 12-month plan. As our arithmetic, that is roughly $153 to $190 a month at two lessons a week. Note that Brighterly is also one of the companies that publishes its own Kumon and Mathnasium comparisons. Outschool is a different shape entirely: a marketplace where independent teachers set their own class prices, so the right comparison is class by class.
Who each one is for
Selection guide (format, price model and logistics, not outcomes)
Choose Kumon if: you want a daily practice routine in math, reading or both, a center within easy reach, and a child who will do short worksheets every day. Ask the local center for its monthly fee per subject before you enrol.
Choose Mathnasium if: you want math-only instruction built from an assessment, and the option to move between a center and live online sessions as your schedule changes. Get the local center's price in writing.
Choose Thinkster if: you want an online-only arrangement with a published starting price, the same tutor each week, and a parent dashboard you can check from work. Confirm the price for your child's grade band, which can be higher than the "from" figure.
Choose Brighterly if: you want published per-lesson pricing for 1:1 math or reading and are comfortable committing to a multi-month plan for the lowest rate.
Choose Varsity Tutors if: you need tutoring beyond math and reading, such as science, languages or test prep, from one provider.
Choose Outschool if: you want small-group classes and are happy to compare teachers and prices one class at a time.
Why this comparison exists, and how we built it
When we mapped the K-12 tutoring searches parents make, the top answers for "Kumon vs Mathnasium" were written by tutoring companies, including two that sell a competing service. That is the gap this page fills: a dated comparison written by a publisher with no tutoring product. We opened each vendor's own homepage, pricing page and FAQ on 4 October 2026, in a browser where a page needed JavaScript to show its prices. We did not use search snippets, review sites or competitor blogs for any figure. Where a vendor does not publish a price, the cell says "not published" and links the vendor's own page. Vendor claims about results are attributed, not adopted.
No company on this page paid to be included, and this page has no affiliate links. If tutoring is one line in a wider education budget, see our homeschool curriculum for working parents comparison and our guide to employer tuition reimbursement.
