- The question comes down to: Should you put money into your 403(b) or pay
- down your mortgage faster? When deciding such questions it is useful to
- do a "what if". What if you are in the top income tax bracket... say 35%
- (we'll include a few points of state tax. This is only a back-of-the-envelope
- calculation anyways. What if your mortgage is at 9%... (You can get a
- slightly better rate with a 15 year mortgage, but it will probably not affect
- the outcome.) What if you expect to get 8% return on your 403b... (We'll
- say you are investing in long term treasuries.)
-
- PAYING OFF THE MORTGAGE ROUTE
-
- You earn $1. After taxes you have $0.65. You send $.65 to your mortgage
- banker. Next year you have to pay .09*.65 = $0.059 less interest. But
- since that interest was tax deductible, you are really only saving
- (1-.35)*.059 = $0.038. So the net result is that next year you will have
- made a return of .038/.65 = 5.85% return on your money. (To be sure you
- won't have made any money, but as Ben Franklin liked to say, "A penny saved
- is a penny earned.") 15 years from now, your $.65 compounding at 5.85% will
- be worth $1.66.
-
- 403b ROUTE
-
- You earn $1. It goes into your 403b pretax. After 15 years your $1 compounding
- at 8% will be worth $3.30. Then (say you are over 59.5 years old) you withdraw
- it from your 403b and pay tax. Tax =.35*3.3 = $1.16. Net return
- is $3.30 - 1.16 = $2.14.
-
- As we can see, even if my numbers are off or this isn't your exact situation,
- you are far more likely to come out ahead by investing in a 403b. "Borrow
- the money for your IRA -- even if you have it." --Strategy #119 "Wealth Without
- Risk" by Charles Givens. You get the added bonus that the interest on the
- money you are borrowing is tax deductible.
