How to Use These Two Calculators (Step by Step)

These tools help you figure out if a bet offers good value — that is, whether the odds are better than the true chance of winning. Here's how to use them together:

1. Step 1: Look at the odds from your bookmaker (e.g. 3.0 or 2/1). Enter them into the Probability Calculator on the left.
2. Step 2: The calculator will show the implied probability — what chance the bookie thinks the horse has.
3. Step 3: Ask yourself: do I think the horse has a better chance than that? Use your own judgement based on the form, ground, pace, trainer, etc.
4. Step 4: Enter your own estimated win chance into the Value Bet Calculator on the right, along with the same odds.
5. Step 5: The tool will tell you if your view creates a value bet — meaning you're getting better odds than you should.

🧠 Example: Odds of 3.0 mean a 33.3% chance. If you believe the horse has a 40% chance, then your edge is +6.7% — that’s a value bet.
