Now that you have the RV all set, you want to have a fishing boat to go with it. The boat you want is a MODEST $71,250. You are able to place $2,420 in to an account at the end of each year. No balance on year 0. First deposit is on year 1. But, you know that won't get you there. You are retiring in 15 years. You are expecing some bonds to mature soon (5 Years). Start the savings account now.. 5 years from now, you will have $$ from bonds to apply to this loan. If you can get a 4.01% rate on you account (PYCY)... how much do you need from your bonds to make this work?
