Polymarket profit calculator
Each winning share pays $1. Your profit is $1 × shares minus what you paid and any taker fee. The calculator also shows the result of selling early and your break-even probability.
Example
100 YES shares at 40¢ cost $40. If YES wins they pay $100, a profit of about $60 before fees. If NO wins you lose $40. If the price climbs to 65¢ before the event, selling returns about $65.
