Equity Calculator.
Hand vs. range equity in seconds.
The Equity Calculator lets you compute hand versus hand or hand versus range equity using Monte Carlo simulation. Input hands using the 13x13 grid selector, standard range notation (e.g., "AA,KK,AKs"), or the card picker for specific combos. Select a board, set the number of simulation samples (10K to 1M), and get equity results in seconds. An equity bar visualization makes results immediately clear. The calculator integrates directly with the Hand Replayer — one click fills in the hand and board from any replayed hand, so you can instantly check "was I ahead?" without manual input.
Why It Matters
- Calculate equity for any matchup — hand vs. hand, hand vs. range, or range vs. range
- Auto-fill from the Hand Replayer for instant post-hand equity checks
- Configurable precision from quick estimates (10K) to high accuracy (1M samples)
- Visual equity bar makes results immediately clear
