18% pretax, so like, 36% post tax/other deductions. Post tax makes more sense as a way of checking this kind of stuff given that is the actual money you have.
If I wanted to though I could bring it down to 12%. My base is about $400 biweekly, but I pay $600. That's $200 extra directly on the principal. If I was not paying that, only like $200 would be going on the principal as about half is interest. Kinda crazy actually.
I suppose I could take that $400/mo and invest it instead but in the grand scheme of things, even with a higher investing interest rate, would it really net me more money in the end given I owe way more on the house than what I'd have in the investment account? Probably not. Not to mention that at the start you're realisticly paying more like 50% interest on the mortgage, so it makes more sense to try to pay it off faster, at least at the beginning. Once the mortgage is paid off then I can take some of that money and put it towards investments, but by that time the hydro bill is going to be like $400/mo and so will every other bill. Cost of living keeps going up. It seems to be a trend that hydro, gas and other expenses keeps going up year after year.
Come to think of it, I'm curious how many years I have left on the mortgage at the current payment rate, I'd have to see if that's data my bank has. My old bank used to show it in the mortgage statement but current bank does not.
