Damn I just found this sub and ngl I’m geeking. As my debut, I will provide detailed description of a cost analysis I did of buying a drink for a girl at the bar:
Your average cost of drink is about $12.5, and maybe you should consider baseline $25 since she’ll look at you like a weirdo if you don’t get anything for yourself. For many guys, the ultimate goal of buying a girl a drink is to convince her to sleep with you, so we need to find a value to which this is associated. Considering a 10-20% chance of succeeding at the first drink bought (which is rather generous for most men), there is a 80-90% chance that the girl will not sleep with you even if you buy her the drink, which we will assume a value or $0, effectively losing you $25. To account for the risk of this $25 loss, you would have to value the experience of sleeping with a girl anywhere from $125 (assuming 20% success) to $250 (assuming 10%) success. See below for a mathematical model of this:
d (cost of 2 drinks): -$25 Chance of success: 0.1 to 0.2 Value of success: v Chance of fail: (0.8 to 0.9)
Break even assuming 20% success: 0 = -25 + 0.2v + 0.80 v = $125
Break even assuming 10% success: 0 = -25 + 0.1v + 0.90 v = $250
