Does this calculator support PLO8 and Omaha 8 or better?

Yes. Hi-Lo mode is built for PLO8 / Omaha 8-or-better split pots. You see total pot equity plus HI and LO half-pot equity, scoop frequency, split frequency, and chop equity.

Can I compare ranges instead of exact hands?

Yes. Switch any hand to Range mode and pick Top 5% through Top 50% presets or a custom percentile band. Range-vs-range matchups use Monte Carlo with a random combo drawn from each range every iteration.

Does it work for 5-card PLO and 6-card PLO?

Yes. Choose 5 Card or 6 Card for high-only Pot Limit Omaha, or Big O for 5-card Omaha Hi-Lo. Range mode is available for all variants.

Is postflop equity exact or simulated?

Postflop spots with a partial or complete board use exact enumeration of every legal runout. Preflop and range matchups use fast Monte Carlo simulation with a reported margin of error.

Can I share a hand setup with a friend?

Yes. The Share button copies a URL that restores the game type, board, hands, ranges, dead cards, and locks — useful for study groups and forum posts.

Workflow

How the equity calculator works

1. Pick cards or ranges

Tap the board and hole-card slots, or switch a player to Range for percentile-based preflop matchups.

2. Exact or Monte Carlo

With flop, turn, or river cards showing, the engine enumerates every legal completion. Preflop and range spots use WASM Monte Carlo with a shown margin of error.

3. Read EV & share

Compare win equity, hi-lo splits, scoop odds, and chops. Copy a share link that reloads the full setup.

Range calculator

Percentile range matchups — not just hand vs hand

Studying whether Top 5% vs Top 50% is a profitable call? Toggle Range on any hand, pick a preset or drag custom percentiles, and get range-vs-range EV. Strength tables are built from Monte Carlo vs a random hand for each game type — PLO4, PLO5, PLO6, PLO8, and Big O.

Quick presets

Top 5%, 10%, 20%, 30%, 40%, or 50% — common study bands without touching sliders.

Custom slices

Any percentile window. 0% always means the strongest combos in the ranking.

Symmetric dealing

Each simulation iteration samples fairly from every active range so results match other major Omaha calculators.

PLO8 & Big O

Hi-lo equity beyond a single number

Split-pot Omaha needs more than one percentage. The calculator breaks down where your EV comes from and how often you scoop or share.

Total %Your combined pot equity from high and low halves.

HI / LOEquity earned from each half of the pot (up to 50% each).

scoopHow often you win both high and low outright.

split / tieHow often you share a half or lose EV to chops.

FAQ

Common questions

Is this a PLO equity calculator only?

No. It covers 4-card PLO, 5-card PLO, 6-card PLO, PLO8, and Big O — high-only and hi-lo — with the same interface.

How accurate is preflop equity?

Known-card spots use Monte Carlo with a reported ± margin. Range matchups sample from precomputed strength rankings with enough iterations to align with established Omaha calculators on standard tests like Top 5% vs Top 50%.

Do I need an account?

No. The calculator is free and runs entirely in your browser. Share links encode the setup in the URL hash.

Looking for preflop strategy ranges too?

OmahaMate also offers solver-backed PLO8 preflop ranges and a preflop trainer with instant EV feedback — separate from this equity tool but built for the same study workflow.
