Saving as little as the price of a cup of coffee, about $2 per day, could put you on the road to a more comfortable retirement. You can invest as little as your employer allows under their retirement program. However, by contributing just $2 per day ($60 per month) starting today, those funds may grow to almost $60,000 in 30 years! (Account values fluctuate with market conditions and, when surrendered, the principal may be worth more or less than the original amount invested.) If you decide that you can afford $4 per day ($120 per month), your savings may be even greater.
