Pre-paying a mortgage?

I've been asked if it makes sense to make pre-payments on a mortgage? Disregarding income taxes for the moment, it usually does. If you have $10,000 earning interest of say 3 percent, and your mortgage has a rate of 6.5%, you "earn" an additional 3.5% by investing the $10,000 into your mortgage. The money you will save over the life of the mortgage, will give you a return of 6.5% on your $10,000. Not having to pay interest of 6.5% is the same as earning it. One problem with doing this is you can't easily get your $10,000 back out of your mortgage if you decide you need it.
Taking income taxes into account complicates the situation. Not having to pay taxes on the 3% earnings of the $10,000 lowers your taxes by let's say $45/year. Not being able to deduct the interest on $10,000 of mortgage, raises your taxes by about $95/year, so you lose $50/year here, but that is offset by you earning an additional $350/year. I assumed a 15% tax bracket here, so I think we can say, income taxes reduce the benefits I wrote about in the first paragraph, but only by 15%. So in this case, you only got 85% (1.00 - .15) of the benefit. If your tax bracket is higher and/or you pay state income taxes, your benefit will be reduced more. Also, a lot of people don't itemize, so a lost mortgage deduction, is irrelevant, which would mean, pre-paying your mortgage lowers your income taxes since your interest income is less.
Debt isn't everything some people claim it is. The value of its write-off is in many cases, overstated.
