This page will calculate how much you will save by bringing your lunch to work instead of going out.
This calculator assumes that you work 50 weeks a year, and that you deposit your savings once a year.
Penny Wise but Pound Foolish?
Depending on your job, you might find that going out to lunch with your colleagues is a valuable networking opportunity that could lead to promotion. You can save money on expensive takeout, but don't miss the chance to socialize with your co-workers.
