Let’s talk about the rule of 72. It’s a term some of you may never have heard of, but it can be a quick and useful way to estimate the number of years it will take to double your return given a fixed rate. The hardest part is assuming what a fixed rate return should be. Here’s an example: You invest $100,000 at 6% per year, so it will take roughly 12 years to double your money. You can figure that out by dividing 72 by 6% to get 12.

When Jackie and I sat down to talk about joining our bank accounts, we flipped a coin to decide whose bank we would stick with. I lost, so we merged all of our money into Jackie’s bank. Of course, in hindsight I can see how silly this is.

Who doesn’t love credit cards? They give you the opportunity to carry a balance while also rewarding you for your spending, providing cash back and points. Credit cards are meant to encourage you to extend yourself though. Carrying a balance from month to month will only increase the total amount you pay in interest. And even if you’re someone who pays your credit card off each month, studies show you’re still spending an average of 18 to 20 percent more than you would if you used cash or a debit card. Psychology shows us we feel differently about seeing a checking account going down versus watching the balance of your credit card increase.

There are so many choices to make, and we often focus most of our attention on things like retirement plans and health insurance.

Do you have family meetings in your house? Dedicated time each week or month to discuss events, changes, or money? My parents sat my sister and me down regularly for family meetings, even discussing finances with us. Admittedly, I remember my own loathing during these meetings, wishing I was somewhere else, but as an adult I recognize how influential those meetings were on my own relationship with money.

At nearly four years old, my daughter is a bit young for assigned chores that will earn her money, but when the time comes, my wife and I plan to give her an opportunity to do just that.
