You have loser friends. I inherited some money recently, which was not insignificant, although it was not a fortune. I paid off all my bills, had one indulgence-- I bought another pinball machine, then with most of the rest, I set up a trust for my son, and a retirement fund for DH and me. I also took $10,000 to invest in the stock market. I have already earned 10% over my initial investment, so I chose my stocks really well. I didn’t know much about the stock market, but I spent a month researching, and it paid off. I have another $10,000 in a savings account for emergencies.
We considered buying a new car for DH (I bought a new car in 2016), but decided to get an evaluation on his current car as though we were buying it, and then fix everything they found. We put $2,600 into it, but it has had the timing belt replaced, and the clutch was replaced three years ago, so it should not need anything major (including brakes and tires) for at least four years. As soon as it does need something major, we will buy a new car then.
Thanks to paying off every speck of bill we had (we had bigger bills once upon a time, but now we don’t even have anything small-- we are not even paying insurance, because we paid it all at once, and saved about $125), we are putting more into savings, and also thanks to our son being old enough to stay by himself for a while after school, I am working more, so in four years we will be able to buy a car outright and still have money in savings.
The trust for our son should increase by 25% by the time he is 18, and the retirement account will pay out about $1,200/month when it matures. Right now, all dividends reinvest. My husband will have a pension in 10 more years; in 15, I will have social security, and he will have SS in 19 years. The investment account starts paying in 20, so I need to work for 20 more years, but I think I can handle that, especially since I can work part time after 15.
Now, anecdote is not data, but my brother has behaved similarly with his money. He didn’t even buy a pinball machine. His only indulgence was to buy first class tickets instead of coach to our mother’s memorial.
