Pot odds in one page
A fast way to decide whether a call is mathematically sane—no solver required.

Pot odds compare the cost to call with the total pot you can win if you call. They tell you the minimum equity you need to continue, ignoring future action for the moment.
The formula
Pot odds = call amount ÷ (current pot + opponent’s bet + your call).
Example: pot is $80, villain bets $40. You must call $40 to win a final pot of $80 + $40 + $40 = $160.
Your price is 40/160 = 25%. You need roughly 25% equity to break even on the call if there is no more betting.
Comparing to outs
On one street, the rule of 2 and 4 estimates equity: outs × 4 on the flop (to river), outs × 2 on the turn (to river). Compare that rough equity to the pot odds threshold.
Caveat
If you call and face future bets, your realizable equity drops—tighten up in bloated pots without position unless you have a clear plan for later streets.
