Thread: Tournament Winnings Equation

Here is what I'm looking for. To buy into a tournament a user must pay a buy in, say $10. If the user wins the first round match they advance to the 2nd round. They then can buy out of the tournament ($20), or play again. If they win they would then have $40. They can follow this pattern for a certain number of rounds. They can buy out or keep playing.

I can't for the life of me figure out the equation to use get the players current winnings based on buy in and their current round. Please help!


I thought it would be as simple as buy in * round, but clearly it's a little more detailed then that.


Buy in - $10
round 1 - $10
round 2 - $20
round 3 - $40
round 4 - $80
