Pot odds price a call. They do not estimate your equity.
A clean formula can still produce a bad poker conclusion when the range or future-action model is missing. First learn the immediate price; then state what the price cannot answer.
How do you calculate pot odds?
Divide the amount you must call by the pot after your call. If the pot is 150 and calling costs 50, the pot becomes 200, so you need to win 50 ÷ 200 = 25% of the time to break even. That is the price of the call — not a reason to make it.
Immediate-call model
Compare the call with the pot after calling.
Let C be the amount you must call and P be the pot currently visible after the opponent’s bet but before your call.
required equity = C ÷ (P + C)
If the pot was 100 and the opponent bet 50, the visible pot is now 150. Calling 50 creates a 200 pot, so the simplified break-even threshold is 50 ÷ 200 = 25%.
Model boundary
A threshold is not a call recommendation.
You still need a defensible equity estimate against an explicit opponent range. Future betting, rake, reverse implied odds, fold equity, and imperfect equity realization can change the decision. This lesson checks arithmetic only.

Common questions
Questions people ask about pot odds
How do you calculate pot odds?
Divide the amount you must call by the pot after your call. If the pot is 150 and calling costs 50, the pot becomes 200 and the break-even threshold is 50 divided by 200, or 25%.
What equity do you need against a half-pot bet?
25%. Against a one-third-pot bet you need 20%, against two-thirds pot 28.6%, and against a pot-sized bet 33.3%. Facing a bet of b times the pot, the threshold is b divided by 1 plus 2b.
Do pot odds tell you whether to call?
No. They give you the price only. To turn that price into a decision you still need an estimate of how often you win against the hands your opponent actually holds, and the price ignores later betting, rake, and how often you realise your equity.
