Sports betting analytics · not a sportsbook

Find mispriced lines. Size every bet with math.

BetMetric compares prices across sportsbooks, strips out the vig to get a fair price, and uses the Kelly criterion to tell you how much the edge is worth staking.

How it works

Three steps from a price to a stake

01
Compare odds across books
The same side of the same game is priced differently from book to book. The scanner lines them up and flags the best available price.
edge = best price − fair price
02
Remove the vig for a fair price
Every book bakes a margin into its odds. Strip it out of a two-way market and what is left is the fair probability, and the fair odds.
fair p = implied p ÷ (implied p + other side)
03
Size the bet with Kelly
If the price beats the fair price, Kelly turns the edge into a stake: bigger edge, bigger bet, and no edge means no bet.
stake = bankroll × (b·p − q) ÷ b

+EV explained

What a +EV bet actually is

EV is expected value: the average result of a bet if you could place it over and over. A price is +EV when the odds pay more than the true chance of winning says they should.

The catch: +EV does not mean this bet wins. In the example, the bet loses 45 times out of every 100. The edge only shows up across many bets, and only if your fair probability is right. It is an estimate, which is why BetMetric derives it from de-vigged market prices instead of gut feel.

Worked example

EV = p × profit − (1 − p) × stake

Fair win probability (p): 55%
Odds offered: +100 (2.00x)
Stake: $100
If it wins: 55% × $100 = +$55.00
If it loses: 45% × $100 = −$45.00
Expected value: +$10.00 per $100 = +10%

Illustrative math, not a prediction or a promise of results.

The tools

One scanner, one sizer, one builder

Three tools that work together: find the edge, size the bet, then combine legs without losing track of the math.

Tool 01

24/7 Live +EV Odds Scanner

Every line, de-vigged and ranked by expected value, so the best prices sort to the top instead of hiding in a tab per sportsbook.

FAQ

Straight answers

What is +EV?

+EV means positive expected value: the odds pay more than the true chance of winning says they should. Over a large number of bets at those prices, the average result is positive. Any single bet can still lose, and the estimate of the “true chance” can be wrong.

Do you guarantee profit?

No. Nobody can guarantee profit from betting. BetMetric gives you math and information: prices, fair odds, expected value and stake sizes. You can lose money, including with +EV bets, and past results do not predict future results.

Which sports and sportsbooks does it cover?

NBA and NFL. The scanner takes live prices from DraftKings, FanDuel and BetMGM and compares each one with a fair price built from Pinnacle's line (with the vig removed). When Pinnacle does not quote a matching line, it uses an average of the books instead and labels the row “Consensus”. Coverage changes as books and states change.

How fresh are the odds?

Live odds are shared and refreshed at most every few hours, so a price can move before you bet. VIP and above can force a refresh once an hour. If a sport is out of season or the data quota is used up, the dashboard switches that sport to clearly labeled simulated lines. Always confirm the price with your sportsbook.

What does each plan include?

Free gives you the calculators and a small live preview. Starter adds the live NBA and NFL board, half Kelly and 2-leg parlays. VIP unlocks the full board, every Kelly multiplier, 8-leg parlays and the full AI generator. Annual adds CSV export and the Pinnacle-verified filter. Lifetime adds the Bankroll Simulator and the Founding Member badge. See the comparison table on the pricing section.

What happens after I buy?

Checkout takes you back to the dashboard. Click Sign in with the same Whop account you used to buy, and your plan unlocks automatically. If something still looks locked, sign out and back in, or contact support.

How do I cancel?

Go to your Whop Orders page, open the plan and choose Cancel subscription. You keep access for the period you paid for. If you cancel before the 7-day VIP trial ends, you are not charged for the first month. One-time Lifetime purchases do not renew.
