PLO Mentor

PLO Equity Calculator

Calculate PLO4, PLO5, PLO6 and Omaha Hi-Lo equity for exact hands, percentage ranges and custom range syntax.

The PLO Mentor Equity Calculator compares exact hands, partial hands and ranges in 4-card, 5-card and 6-card Pot-Limit Omaha. It also includes a dedicated 4-card Omaha Hi-Lo mode for PLO8 calculations. You can analyse two to four players from preflop to river, with every calculation performed directly on your phone.

One PLO equity calculator for several Omaha formats

Adding extra hole cards or splitting the pot between high and low changes equities dramatically. PLO Mentor lets you switch game type at the top of the Equity tab so that the hand slots, ranges and results match the format you are studying.

Game Exact hands Percentage ranges Custom range syntax
4-card PLO High Yes Yes Yes
4-card Omaha Hi-Lo / PLO8 Yes Yes Yes
5-card PLO Yes Yes Yes
6-card PLO Yes No Yes, with one range player at a time

Standard Omaha rules apply in every mode: a player must use exactly two hole cards and three board cards. In Hi-Lo, the high and low halves are evaluated separately and may use different hole-card combinations.

If you are looking to find the best 5 card plo equity calculator, this is the one for you.

Exact hands, partial hands and full ranges

Choose Cards when you know a complete hand. You can also enter only part of a hand: empty slots represent unknown cards, allowing questions such as how aces with two unknown side cards perform against a known hand.

Choose Range when the question concerns a group of hands rather than one combination. This is where PLO Mentor goes beyond a basic hand-versus-hand calculator. A player can be represented by a percentage, a structural range expression or, in 4-card PLO High, a frequency-weighted solver opening range.

Percentage ranges make broad comparisons simple

A value such as 25% selects the strongest quarter of starting-hand combinations in the ranking used for that game. A band such as 20%-40% removes the strongest 20% and selects the next 20% instead. This is useful when modelling a wider calling range rather than an uncapped opening or raising range.

Percentage ranges are available in 4-card PLO High, 4-card Omaha Hi-Lo and 5-card PLO. The ordering changes with the game: Hi-Lo correctly moves strong A2 combinations towards the top, while the five-card ordering is based on equity against a random five-card hand.

Percentage does not mean position-specific strategy

A top-X% range is a generic hand-strength order, not a solved opening, calling or 3-betting strategy. Use it when range width is the main information you have. For a more realistic structural range, combine filters or use the dedicated PLO4 solver opening buttons.

Build more realistic ranges with syntax and filters

PLO Mentor accepts ProPokerTools-style range syntax. Terms can be combined with a comma for OR, a colon for AND, an exclamation mark for NOT and parentheses for grouping. This makes it possible to describe the shape of a range instead of listing every individual combination.

Example Meaning
RR:$ds Paired and double-suited hands
($0g,$1g):$ds Double-suited rundowns with zero or one total gap
30%:!AA** The top 30% of PLO4 hands with aces removed
15%-40% A middle band that excludes the strongest 15%
A:(K,Q,J) An ace together with a king, queen or jack

Percentage ranges and filters can also be combined, for example 30%:$ds or 10%-25%:!AA**. Board cards and cards already assigned to other players are removed automatically.

Solver opening ranges for 4-card PLO

In 4-card PLO High, the Range view includes quick buttons for EP, MP, CO, BTN and SB opening ranges. These are not generic top-X% selections. Each hand is weighted by the frequency with which the solver opens it in the underlying 6-max, 100bb solution.

This lets you compare a hand or another range against an actual position-specific opening strategy. Solver opening buttons are intentionally limited to 4-card High; they are not shown in Hi-Lo, five-card or six-card modes.

Omaha Hi-Lo equity with hi, lo and scoop results

Switching to Hi-Lo changes both the starting-hand ordering and the result breakdown. The large figure remains the player’s share of the whole pot, while the calculator also displays the high share, low share, scoop frequency and how often a qualifying low is possible.

This is important because two hands with similar total equity may reach it in very different ways. One may dominate the high half while another makes more lows or scoops more frequently.

6-card Omaha equity calculations

The 6-card mode supports exact hands and custom range expressions from preflop to river. The example below compares an exact AAKKQJ hand with the structural range RR:$ds on a flop.

Because the six-card starting-hand space is extremely large, percentage ranges are not available and only one player can use Range mode in the same calculation. These limits keep the mobile calculator practical while still supporting useful hand-versus-range analysis.

Heads-up, multiway, preflop and postflop

Start with two players or add opponents for three- and four-way analysis. Leave the board empty for preflop equity, or enter three, four or five community cards to calculate flop, turn or river situations. Card removal is handled automatically across every hand, range and board.

When the number of possible runouts is small enough, every board is enumerated and the result is marked as exact. Larger range or preflop calculations use adaptive simulation, normally targeting approximately ±0.2 percentage points at 95% confidence. A status line tells you whether the result was exact, simulated or approximate because of heavy range overlap.

What makes PLO Mentor one of the best equity calculators for Omaha?

The best equity calculator is not only accurate. It should also make useful questions quick to enter and its answers easy to understand. PLO Mentor combines a clear mobile interface with several input levels: exact cards for a known showdown, partial hands for incomplete information, percentages for range-width estimates and syntax for more realistic hand structures.

  • Clear results: equity, wins and ties are separated in High games, while Hi-Lo displays high, low and scoop information.
  • Flexible ranges: use percentages, bands, filters, logic operators and structural macros.
  • Multi-format support: study PLO4, PLO5, PLO6 and 4-card Omaha Hi-Lo in the same app.
  • Heads-up and multiway: compare two to four players.
  • Preflop and postflop: calculate with an empty board or add flop, turn and river cards.
  • Private and offline: the engine and ranking tables are bundled with the app, so hands and ranges are calculated locally without being sent to a server.

These features make PLO Mentor especially useful for players who want a capable Omaha calculator without opening a desktop solver or learning a complicated workflow.

Frequently asked questions

Which Omaha games does the calculator support?

It supports 4-card, 5-card and 6-card Pot-Limit Omaha High. It also includes a 4-card Omaha Hi-Lo mode using an eight-or-better qualifying low.

Can I calculate equity against a percentage range?

Yes. Percentage ranges and percentage bands are available in 4-card PLO High, 4-card Omaha Hi-Lo and 5-card PLO. Six-card Omaha supports exact hands and custom range syntax but not percentage ranges.

What range syntax can I use?

You can use exact rank patterns, percentage ranges, suit-shape and rundown macros, plus OR, AND, NOT and grouping operators. Examples include RR:$ds, 20%-40% and 30%:!AA**.

Does it work for postflop equity?

Yes. Enter a flop, turn or complete board to calculate postflop equity. With small enough exact-hand situations, the app enumerates every possible remaining board.

Does the equity calculator work offline?

Yes. The calculation engine and range tables are stored in the app. Calculations run locally on the device and do not require an active internet connection.
