But if you want a donut forget the whole thing.

From YAME's Seattle Bureau:

A $4/day coffee habit is worth almost $19,000 over 10 years (assuming that, alternatively, $4 per day could be saved at 5% annual interest compounded daily).

Over 20 years, it’s worth just over $50,000, $21,000 of which is interest which is like 5,250 free lattes (which would take about 14.5 years to drink).

Or, after about 14 years, the savings and interest accumulated could pay out $4/day for life. That’s a free latte every day for the rest of your life! AND, when you die, there would still be $29,000 in your account. How cool is that?
