Poker Pot Odds Calculator

Last updated: May 16, 2026

Pot odds formula: Required Equity % = Call Amount ÷ (Pot + Call Amount). A half-pot bet requires 25% equity to call profitably. A pot-sized bet requires 33%. Compare your equity (from the Rule of 4 and 2 or the RiverOdds calculator) to the required equity from this table. If yours is higher, call. If lower, fold.

Definitions

Pot Odds
The ratio of call amount to total pot after calling. Defines minimum equity needed to call profitably.
Required Equity
Minimum win probability for a call to be break-even. Calculated as call ÷ (pot + call).
Implied Odds
Pot odds adjusted for expected future winnings if you hit. Critical for set mining and deep-stack draws.
Reverse Implied Odds
The risk of completing a draw into a losing hand. Penalty applied to call decisions.
Rule of 4 and 2
Outs × 4 (flop) or × 2 (turn) ≈ equity. Quick table reference for comparing to required equity.

Frequently Asked Questions

How do you calculate pot odds in poker?

Required equity % = Call Amount ÷ (Pot + Call Amount). Example: $100 pot, opponent bets $50. You call $50 into $200 total (100 + 50 + 50). Required equity = 50/200 = 25%. If your hand has 25%+ equity, calling is profitable. Below 25%, fold.

What pot odds do I need for a flush draw?

Flush draw has 35% equity flop-to-river (9 outs × 4 from Rule of 4 and 2). Required pot odds: anything better than 35%. A half-pot bet requires 25% equity — flush draw clears this. A pot-sized bet requires 33% — flush draw still calls. A 2× overbet requires 40% — flush draw must fold without implied odds.

Is pot odds different from implied odds?

Yes. Pot odds use ONLY the current pot. Implied odds add expected future winnings if you hit. With deep stacks and a draw, implied odds let you call thin pot-odds spots because hitting the draw extracts more bets. Pot odds is the strict math; implied odds is realistic adjustment.

What's the easiest way to calculate pot odds at the table?

Memorize 5 common ratios: 1/4 pot = 17%, 1/3 pot = 20%, 1/2 pot = 25%, 3/4 pot = 30%, pot = 33%, 2× = 40%. Then compare to your equity from the Rule of 4 and 2. Most decisions become instant — flush draws (35%) call up to pot-sized; OESDs (31%) call up to 3/4 pot; gutshots (16%) fold to anything bigger than 1/4 pot.

Does pot odds account for the rake?

Standard pot odds calculation does NOT include rake. For practical play in low-stakes games, ignore rake — it's already 'baked in' to the math. For thin marginal decisions at high-rake games (live $1/$2 with $5 cap), subtract expected rake from pot won when calling. Most online calculators ignore rake.
