Let’s say I still owe 100k at 2.5% on my house and am starting at $0 in saving at 5% but have an extra $500 a month to put into either. Is there an online calculator or something that kind of shows you the different outcomes? ThanksIf the interest rate on your mortgage is 2.5% and the interest rate on your saving account is 5%, you net 2.5% every month by not paying extra on your mortgage, assuming you have the extra money to net the 2.5% on.
Money markets are paying 4.5-5.2% right now. If that yield drops below your mortgage rate, then at that point you should start paying the extra money on the mortgage rather than sit on it, assuming you can't make it go to work for you elsewhere at greater than 2.5%. The difference there is money market accounts carry no risk so long as you keep each account at an institution under 250k. 5% is a hell of a return on a no risk whatsoever investment and rates haven't been this high since the early 90s. Who knows how long it will last.
I guess we could also discuss the real rate of inflation and the effect that has on sitting on money like that below the rate of inflation while also considering the effect of inflation on mortgage interest/principal.
