To pay off or not to pay off mortgage - pls check my #'s?

19 years ago

I'm really drawn to paying off our mortgage, just to be debt free as we contemplate pretirement options for the next few years. There are no issues of liquidity or safety nets, those are all well covered elsewhere. This is a numbers question.

The mortgage has 3 years left. Balance is 50k at 4.75% fixed. (we prepaid some along the way). We are in 28% tax bracket with another 7% to the state = 35% total tax bite.

I had presumed from my reading here that paying this off would be financially dumb, given the excellent rate. And it does seem like the numbers are also telling me that.

For simplicity's sake, I'll use a secure CD type interest earnings rate of 5.25%

Option A: put the 50k into a CD and earn 5.25% over three years. Earns $8509, becomes $5530 after taxes. Pay the 36 mortgage payments totaling 54k, and pocket $1304 from the $3728 mortgage interest effect on taxes. At the end of the stretch, I've paid out 54k and netted $6835 in earnings and tax reductions.

Option B: Pay off the 50k mortgage and forsake the CD earnings and the mortgage tax deduction. Deposit the monthly 1500. With comparable 5.25% earnings, my 54k deposited over 3 years becomes $58347 with a net gain after taxes of $5425. I am out $1410 compared with A.

If I use the arguably more available 5% instead of 5.25%, I get $6551 net for A vs. $5284 for B. Still favors A by $1267.

Soooooooooo;

Botom line is that I need to want to be done with this mortgage badly enough to give up 1250-1400 cold hard cash to make it happen. True?

I realize I am not factoring in inflation (because 3 year horizon is short and inflation chews on both options, though moreso on B). And I am not considering opportunity to earn more money by taking more risk. (dollars in this scenario are in the accessible and most secure sector of holdings). Still, should I be using other rates? Anything else I am missing here?

I would love to hear there is a way to dump the mortgage without such a big dumb loss. Thank you for contemplating this.
