THE VALUE BETTING ENGINE
Stop guessing.
Start pricing properly.
Use our Expected Value
(EV) Calculator to find true mathematical edges.
It won’t pick winners for you. It will tell you if your bet makes sense.

How It Works
Step 1: Configure Your Setup (Settings)
Before you start, hit the Settings gear. Lock in your currency, preferred odds format, default stakes, and total bankroll. The engine uses your bankroll to calculate precise Kelly Criterion stakes.
Step 2: Calibrate Your Read
Assess the race and determine the horse's true probability of winning. Use the slider to set your own "Tissue Price" before you look at the bookies.
Step 3: Input the Market
Enter the live odds. Toggle between Bookmaker or Exchange (to factor in commission), and set your Each-Way place terms if needed.
Step 4: Secure the Value
The engine instantly exposes the market. If there's an edge, you'll get your Long Term ROI and a suggested Kelly stake. Hit "Add to Tracker" to log it.
This tool assumes your probability assessment is honest and disciplined. 🛡️
