We all work hard for our money, so it's amazing to see how many of us waste it every week.

It's never a major purchase that bleeds our wallets dry, its the daily small purchases that we could easily do without.

Check out some of the biggest expenses over the course of a year.

According to the Consumerist the average American worker spends $1,092 every single year on coffee.  That's more than $20 a week.

This is a huge waste when you consider that most workplaces offer some type of coffee for free!

Another major expense was the commute, which ran about $1,476, meaning your coffee budget is only slightly lower than your gas budget.

Neither one comes close to what you're spending on lunch every day.  The average worker spends an extra $37 a week to eat outside the office, which comes to $1,850 a year.  (Based on working 50 weeks.)

If this seems like a surprise to you, you're not alone.  About four times as many people assumed their commute would cost more than their lunches.
