NEW YORK (MainStreet) — If you have trouble motivating yourself to pack a lunch each day for work, you’re not alone.

Two-thirds of U.S. workers say they buy lunch rather than bring one from home and spend an average of $37 each week as a result, according to a survey of 1,000 employees by Accounting Principals, a staffing agency affiliated with Adecco. To put that in perspective, that means the average worker spends nearly $2,000 each year on lunches out for work.

Then there’s our incredible coffee addiction. Accounting Principals found that half of all workers buy coffee on a regular basis and spend an average of $20 each week in the process, or a total of roughly $1,000 a year. Those who buy both coffee and lunch each day are effectively spending enough money to pay for several month’s rent in most cities.

Some in the office actually spend much more. The study found that men spend are more likely to buy lunch and coffee while at work and spend an average of $46.30 for lunch and $25.70 for coffee each week, or roughly $2,400 and $1,300, respectively.

Many businesses do offer complimentary coffee and a few even provide complimentary lunches, but for those who work at places that don’t, it may be time to reconsider the benefits of making your own at home, or at the very least, to get more creative with what quick and cheap meals you can prepare at work.
