Fold Equity Calculator
The fold % a bluff or shove needs to profit.
How it works
Fold equity is the profit a bet earns from making the opponent fold. A bluff or all-in is profitable when the opponent folds often enough: the more you risk relative to the pot you win, the higher the fold frequency you need.
With no equity when called, the required fold frequency is simply bet ÷ (bet + pot). Adding your equity for the times you are called lowers the bar — a semi-bluff with outs needs villain to fold less often than a pure bluff. This calculator solves the break-even fold frequency for both.
Fold Equity Calculator
Fold equity is the value a bet earns purely from making your opponent fold. This free calculator finds the fold frequency a bluff or all-in needs to break even, given the pot, your bet size and your equity for the times you get called.
How much fold equity you need
When you bet as a bluff you win the current pot if the opponent folds and lose your bet if they call and you have nothing. The break-even fold frequency is bet ÷ (bet + pot): risk a pot-sized bet and you need folds half the time; bet small relative to the pot and you need them far less often.
This is why small bluffs are cheap and large overbets are expensive — the more you risk to win the same pot, the more often the opponent has to fold to make it pay.
Adding your equity when called
A semi-bluff with outs is not dead when called, so it needs less fold equity than a pure bluff. The calculator factors in your equity for those times — a flush draw that wins a third of the time when called dramatically lowers the fold frequency you need.
Enter the pot, your bet and your equity when called to see both the simple required fold percentage and the equity-adjusted break-even point.
What is fold equity?expand_more
The portion of a bet's value that comes from the chance your opponent folds. The more often they fold, the more profitable a bluff or semi-bluff becomes.
How do you calculate required fold equity?expand_more
With no equity when called it is bet ÷ (bet + pot). Adding your equity for the times you are called lowers the fold frequency you need to break even.
Does a draw need less fold equity?expand_more
Yes. A semi-bluff with outs still wins some pots when called, so it requires a lower fold frequency than a pure bluff with no equity.
