5 Card PLO Equity Calculator

The PLO Mentor 5 Card PLO Equity Calculator compares exact five-card hands, partial hands and ranges from preflop to river. Use percentage ranges when you know approximately how wide an opponent plays, or build a more specific range with structural syntax and filters.

Why five-card Omaha needs its own equity calculator

Five hole cards create far more starting combinations, blockers and redraws than standard four-card PLO. A result from a four-card calculator cannot be reused: the engine must deal five cards to each player and still apply the Omaha rule of using exactly two hole cards and three board cards.

PLO Mentor changes every player slot when 5-card mode is selected and evaluates the correct five-card starting-hand space. You can compare two to four players and leave the board empty or add flop, turn and river cards.

Exact hands or percentage ranges

For a known showdown, enter each player’s five cards. For a broader question, switch a player to Range mode and enter a percentage such as 20%. This selects the strongest 20% of five-card starting-hand combinations according to PLO Mentor’s five-card strength table.

You can also enter a band such as 20%-40%. This excludes the strongest 20% and uses the next 20%, which is often a more useful approximation for a calling range than an uncapped top-X% selection.

Custom range syntax for more realistic PLO5 analysis

A percentage is not always enough. Five-card ranges can also be written with rank patterns, suit filters and logical operators. For example, RR:$ds selects paired double-suited hands. A comma combines alternatives, a colon requires both conditions, an exclamation mark removes a group and parentheses keep more complex expressions clear.

Suit-shape macros automatically adapt to five cards. In PLO5, $ds means a 2-2-1 suit structure and $ss means 2-1-1-1. A fully rainbow five-card hand is impossible, so $rb correctly returns an empty range.

Input	Best use
Five exact cards	Review a known hand or all-in
20%	Model the strongest fifth of all five-card combinations
20%-40%	Model a middle band without the strongest hands
RR:$ds	Study paired, double-suited five-card hands
Partial hand	Keep one or more side cards unknown

Heads-up and multiway 5-card PLO equity

Five-card Omaha pots are often multiway, so a useful calculator must handle more than one opponent. PLO Mentor supports up to four players and divides tied pots correctly. The equities across all players always total 100% because each figure represents that player’s average share of the pot.

The example below calculates a three-way flop exactly across every remaining board. This makes it easy to see how a strong-looking hand changes when additional players, blockers and competing draws are introduced.

Preflop, flop, turn and river calculations

Leave the board empty for preflop analysis. Add three cards for a flop, four for a turn or all five community cards to evaluate the current river result. Board cards are removed automatically from every exact hand and range.

With a manageable number of exact runouts, the app counts every possible board and labels the result as exact. Larger preflop and range calculations use adaptive Monte Carlo simulation, normally targeting approximately ±0.2 percentage points at 95% confidence.

Why PLO Mentor can be the best 5-card PLO equity calculator for mobile study

For many players, the best 5-card PLO equity calculator is the one that is both flexible enough for real strategy questions and simple enough to use after a session. PLO Mentor combines a clear card picker with percentage ranges, custom syntax, multiway calculations and an explicit breakdown of wins and ties.

• Easy to use: switch to 5-card mode and enter cards through a visual mobile card picker.
• Percentage ranges: compare a hand with the top X% or a selected band of five-card combinations.
• Range syntax: describe paired, suited and other structural hand groups instead of entering combinations one at a time.
• Multiway support: analyse two, three or four players.
• Postflop support: add any flop, turn or river board.
• Offline calculations: the engine and ranking data are stored on the device, so no hand data is sent to an external server.

Important limitations

The Equity Calculator measures hand and range equity; it is not a complete five-card postflop solver and does not prescribe betting strategies. The position-specific GTO opening-range buttons are currently available only in 4-card PLO High. In five-card mode, use exact hands, percentage ranges or custom range expressions.
