Whether you spend a buck on â€ścheapâ€ť coffee or $3.99 on a fancy latte, that cash adds up quickly. Calculate roughly how much you spend per year on coffee and then think about what else you can do with that money. Pay off debt? Plan a vacation? Save for your kidsâ€™ college education? Then try making coffee at home and carrying it in a reusable cup as many days as you can â€“ and watch your savings pile up!
