Calculate the equity requirement from a known call.
Open →Maximum Break-Even Call Calculator
This tool reverses the pot-odds question. Instead of asking how much equity a call requires, enter your estimated equity and calculate the largest call that would break even under a simple showdown model.
Maximum call = equity × pot available before your call ÷ (1 − equity).
Calculate maximum call
What “pot available” means
Use the amount already in the pot after the opponent's bet but before adding your call. For example, if the pot was 100 and an opponent bet 50, the available pot is 150.
Do not confuse break-even with automatically correct
A mathematical call can still depend on how accurately you estimated equity, whether future action exists, tournament payout pressure, rake or the possibility that apparent outs are not clean.
