Regular savings pays ___% Money Market pays ___%

Explanation / Answer

5) Because the taxes are usually paid annually, we first convert the home equity loan to an EAR to determine the actual amount of interest during that year. The after tax cost of home equity loan, which is tax-deductible, is [(1+0.078/12^12-1](1-0.28) or 6.24%. The dealer's boat loan has a cost of [(1+0.069/12^12-1]=7.77%. Hence the after tax cost of home equity loan is cheaper at 6.24% than the dealer’s boat loan at 7.77%.
