1. Model Win Probability

This is your model’s estimate of how often the team should win. For example, 60% means the model expects the team to win 60 times out of 100.

2. Fair Odds

Fair odds are the no-vig odds implied by your model. In other words, this is the break-even price your model thinks is fair.

Fair Decimal Odds = 1 / Probability
Fair American Odds = convert the fair probability into American odds

3. Sportsbook Implied Probability

The sportsbook’s odds can be converted into a probability. That tells you what win chance the book is pricing in.

For positive odds: 100 / (odds + 100)
For negative odds: abs(odds) / (abs(odds) + 100)

4. Edge

Edge compares your model probability to the sportsbook’s implied probability.

Edge = Model Probability − Sportsbook Implied Probability

A positive edge means your model thinks the sportsbook is offering a better price than it should.

5. Expected Profit and EV%

Expected profit estimates your average profit or loss per bet if you could place the same bet many times at the same odds.

Expected Profit = (Probability × Profit if Win) − ((1 − Probability) × Bet Amount)
EV% = Expected Profit / Bet Amount

6. Kelly Stake

Kelly sizing suggests how much of your bankroll to bet based on your edge and the payout. Full Kelly is aggressive. Many bettors use half Kelly or quarter Kelly.

Kelly % = ((b × p) − q) / b
where b = decimal odds minus 1, p = your win probability, and q = 1 − p.

Quick interpretation

Fair odds are the no-vig odds implied by your model probability.

Edge is your model probability minus the sportsbook’s implied probability.

Positive EV means your model says the sportsbook price is better than it should be.

Kelly sizing helps translate that edge into a bankroll-aware stake suggestion.
