Pricing
Teacher’s Bet charges nothing for the math. Every calculator on the site is free, the full Learn course is free, and neither asks for an account. The paid tier — Dean’s List, $39 a month or $390 a year — removes the two-hour delay the free board is served on, and will add streamed exchange data and stored history when that feed ships. It does not buy a formula, and it does not buy picks.
Free, permanently
Not a trial. Not a teaser with the good parts removed. The free tier is the entire math stack, and it has no expiry date:
$0 · forever
- Every calculator: no-vig, expected value, Kelly, arbitrage, closing line value, bonus bet, parlay, Kalshi fees
- The full Learn course — de-vigging, +EV, Kelly, arbitrage, closing line value, and the Extra Credit house-edge math
- The formula sheet and the methodology behind the fair line
- Every derivation, every step, on every result
- The board, on a two-hour delay — fair lines across the venues on it, with the age of each price shown on its face. The delay is the paywall; nothing else about the board differs between the tiers
- Arbitrage detection and flagging, on that same delayed board
Arb detection sits in the free column on purpose. The site’s own shelf-life math says a cross-book gap decays in seconds, so an arb flag on a minute-scale refresh — let alone on a board delayed two hours — is not a product worth charging for. It stays a free calculator and a free flag on the board, and the flag carries the age of the prices it was computed from.
Dean's List — $39/month, or $390/year
The paid tier is about latency and archive depth, which are the two things that genuinely cost money to run. One item on the list below is built and running and waits only on checkout; the rest are stated in future tense because they are not.
Dean’s List · $39/mo · $390/yr
- Shipped: the board with the two-hour delay removed — the same soft-book snapshots and the same formulas, served the moment they land instead of 120 minutes later. Free and paid read the same stored rows; the free read is windowed back two hours and the paid read is not. There is no separate, faster polling schedule for subscribers, and this page is not going to pretend there is
- Planned at launch: live exchange fair value, streamed on demand — the Kalshi order book while the game is running, rather than a snapshot. The streaming subsystem is built and tested but ships switched off; it is not running in production today
- Planned: +EV flags against that live fair line — raised the moment a book’s posted price beats it, with the timestamp of both sides of the comparison
- Planned: closing-line-value grading kept as stored history rather than as a number that vanishes when the browser cache clears. Today the Report Card lives in your own browser and nowhere else — the privacy page says so too
The annual price is two months of the monthly price, and that is the whole discount — here is the arithmetic:
So $390 a year is $78 less than paying monthly for twelve months, which is exactly two months free. Nothing else changes between the two.
The founder rate: 12 months, then it ends
The first 100 subscribers pay $25 a month for their first 12 months, then the standard $39 a month. Over that first year:
This is a 12-month discount, not a lifetime price lock. There is no lifetime plan on this site and there will not be one. When the 12 months are up, the standard price applies to the next renewal — that is stated here, and when checkout opens it will be stated at checkout and in the account panel with the date attached.

Billing, renewals and cancelling
The terms, in plain language
Checkout is not open yet. When it opens, these are the terms — on this page, in this wording, rather than buried three clicks deep in a terms document.
- It renews automatically. Monthly plans charge every month on the same date; annual plans charge once a year. It keeps renewing until it is cancelled.
- The amount and the date are shown before you pay — on the checkout page, next to the button that authorises the charge — and again in the account panel afterwards.
- The founder rate expires after 12 months. The next renewal after that is $39. The end date will be on the account panel from the day you subscribe.
- Cancel from the account menu. It opens the Stripe billing portal, where cancelling is one click — no email, no phone call, no chat queue, no “are you sure” retention offer. Two clicks in total, and the second one is Stripe’s.
- Cancelling stops the next charge. Access runs to the end of the period already paid for — a mid-month cancel does not cut you off mid-month.
- Where it works. Washington State law (RCW 9.46.240) restricts the online transmission of gambling information, and whether an analytics calculator falls inside it is unsettled. The cautious reading is the one shipped: requests from Washington are served an HTTP 451 notice on the live board and the odds API, while the calculators, the Learn course and these policy pages are served normally. Dean’s List is priced around the board, so it is not sold into Washington while that gate is up. The terms page has the detail.
- Billing questions and mistaken charges go to alex@teachersbet.com, which is a person, not a ticket queue. See the contact page for response times.
Payments are processed by Stripe. Card numbers never touch this site’s servers — see the privacy page for what is stored.
What paying does not buy
Worth stating flatly, because much of this industry sells the opposite:
- No picks and no advice. No tier says “bet this.” Every output stays a calculation on inputs you supplied or on posted market prices.
- No promise of profit. Nothing on any tier guarantees an outcome. No arithmetic on a posted price can, whoever is selling it.
- No better answer. The paid tier runs the same formulas as the free one. When the inputs contain no edge, every tier prints $0.
- No access to the formulas, because they were never behind a wall. They are published as an MIT-licensed Python library that anyone can install and run.
Why the math is free
Two reasons, both practical. The formulas are public mathematics, already published in the library above, so gating them would be theatre rather than a business. And a calculator that serves a static page costs almost nothing to run — what costs money is a socket held open to an exchange and a tick archive that keeps growing. That is what the paid tier pays for, and it is the only thing it pays for.
Checkout is not open yet. Dean’s List ships when the live exchange data does — leave an address in the app and one email goes out when it opens.
Frequently asked questions
How much does Teacher’s Bet cost?
The calculators, the Learn course and the formula sheet cost nothing and require no account. The paid tier, Dean’s List, is $39 a month or $390 a year. The first 100 subscribers pay $25 a month for their first 12 months, then the standard $39. Checkout is not open yet.
Is Teacher’s Bet free?
Yes, for the math. Every calculator on the site and the full Learn course are free permanently, with no signup, no email and no card. The odds board is free as well, served on a two-hour delay. The free tier is not a trial and does not expire.
What does the paid tier actually add?
Today, one thing: the board without the two-hour delay. The same rows, the same formulas, served the moment they land. When the live exchange feed ships, Dean’s List will also stream fair value from the order book, flag a book’s price the moment it beats that live fair line, and keep closing-line-value grading as stored history. It will not add a formula the free tier lacks, and it will not add picks. Checkout is not open yet.
How do I cancel?
One click in the account menu opens the Stripe billing portal, where the subscription is cancelled in one more click. No email, no phone call, no retention offer. Cancelling stops the next charge, and access runs to the end of the period already paid for.
Is there a lifetime plan or a locked-in price?
No. There is no lifetime plan and no lifetime price lock. The founder rate is a 12-month discount that ends after 12 months, at which point the standard $39 a month applies.
Is there a free trial?
There is no trial, because the free tier is not time-limited. Every calculator and the whole course stay free whether or not anyone ever subscribes.
