If you buy a cup of coffee every day for $1.00 (an awfully good price for a decent cup of coffee, nowdays), that adds up to $365.00 for just one year. If you saved that $365.00 for just one year, and put it into a savings account that earns 5% a year, it would grow to $465.84 by the end of 5 years, and by the end of 30 years, to $1,577.50.
