The other day I was having lunch with a group of colleagues from work. One had just gotten back from Vegas and talked about he had no luck while he was there and lost a shit load of money. We came to find out that his losses were a $1000. Based on his position in the company, he could easily absorb this loss. He is just conservative with his bankroll when he went to the Vegas. The resulting discussion was how much would people to bring to gamble toVegas. Are you aggressive, conservative or somewhere in between? In order to avoid discussing one's individual finances, we created a fictional person. This person's income, which includes the income of the spouse, is 300,000. After paying the mortgage and the bills, making car payments and contributing to the 401k and 529s, the person has 5k per month for discretionary spending. The average bankroll among the group was 5k. I was somewhat higher at 7.5k. How much would you have this person bring?
