How to share income after marriage and kids?
You remind me a lot of myself as I was thinking about marriage. Luckily for me, my wife was much smarter about all this than I was. Hopefully, I can pass along some of her wisdom. Both of us feel very strongly about being financially independent and if possible we both don't want to take money from each other. In marriage, there is no more financial independence. Do not think in those terms. Life can throw so many curve balls that you will regret it. Imagine sitting down with your new bride and running through the math. She is to contribute $X to the family each month and you are to contribute $Y. Then next thing you know, 6 months later, she has cancer and has to undergo expensive and debilitating treatment. There is no way she can contribute her $X anymore. You tell her that is okay and that you understand, but the pressure weighs down on her every day because she feels like she is not meeting your expectations.  Or alternatively, everything goes great with your $X, $Y plan. A few years down the road your wife is pregnant, so you revisit the plan, readjust, etc. Everything seems great. When your child is born, however, the baby has a severe physical or mental handicap. You and your wife decide that she will quit her job to raise your beautiful child. But, the whole time, in the back of her mind she can't get out of her head that she is no longer financially independent and not living up to your expectations. These stresses are not what you want in your marriage. Here is what we do in my family. Hopefully, some of this will be helpful to you. Every year my wife and I sit down and determine what our financial goals are for the year. How much do we want to be putting in retirement? How much do we want to give to charity? Do we want to take any family vacations? We set goals together on what we want to achieve with our money. There is no my money or her money, just ours. Doesn't matter where it comes from. At the beginning of every month, we create a budget in a spreadsheet. It has categories like (food, mortgage or rent, transportation, clothing, utilities) and we put down how much we expect to spend on each of those. It also has categories for entertainment, retirement, charity, cell phones, internet, and so on. Again, we put down how much we expect to spend on each of those. In the spreadsheet, we also track how much income we expect that month and our totals (income minus expenses). If that value is positive, we determine what to do with the remainder. Maybe we save some for a rainy day or for car repairs. Maybe we treat ourselves to an extra fancy dinner. The point is, every dollar should be accounted for. If she wants to go to dinner with some friends, we put that in the budget. If I want a new video game, we put that in the budget. Once a week, we take all our receipts and tally up where we spent our money. We then see how we are doing on our budget. Maybe we were a little high in one category and lower than expected in another. We adjust. We are flexible. But, we go over our finances often to make sure we are achieving our goals. Some specific goals I'd recommend that the two of you consider in your first such yearly meeting: You get out of life what you put into it, and you will get out of your finances what the two of you put into them. By being on the same page, your marriage will be much happier. Money/finances are one of the top causes of divorce. If you two are working together on this, you are much more likely to succeed.
