# Rule of 752: How Small Expenses Can Destroy Your Budget

Small expenses can sneak up on you when you’re not paying close attention to your budget, but here’s a simple way to get yourself back on track.

It’s called the Rule of 752 and it reveals the cost of weekly expenses over a decade.

## Explaining the Rule of 752

Simply multiply any weekly expense by 752 to see the real cost of that expense over 10 years — had you invested the money at a 7% compounded rate of return.

Check out these examples to see how small purchases can add up over time!

### Morning Coffee: \$20/Week

As you head into your favorite coffee shop five days a week, you may not think twice about the \$4 a day tab. But take a look at it this way:

Rule of 752: \$20 x 752 = \$15,040

### Fitness Class: \$30/Week

If you supplement your regular gym membership with one of those fancy spin classes, you could easily be paying \$30 a week or more! See how that adds up:

Rule of 752: \$30 x 752 = \$22,560

### Lunch: \$40/Week

If you don’t bring your lunch to work, you’re probably running to a quick service restaurant, perhaps spending \$40 a week. That’s a lot of money over 10 years:

Rule of 752: \$40 x 752 = \$30,080
