<prompt> Human: New home owner here. Got an amazing deal on my house at 80k. The mortgage is 711 per month. I chose bi-weekly payments because ive heard it takes 7 years off. 30 year loan, Ive never verified that to be true though The break down is pretty much 111 goes to principal, 300 interest, and 300 escrow.thats not exact but is very close That percentage makes me want to puke so I put 100 extra on principal each month. I recently took a pay cut but can still swing the extra 100. My car will be payed off in 8 months. That frees up another 400 per month. When that happens Im considering putting another 150 or 200 of that toward principal.My main questions are.. How much faster will it be payed off by doing Bi weekly payments and an extra hundred. If the biweekly actually shaves,off 7 years but the 100 only takes off like 1 year then Id rather put it toward saving or investments. Same with the car money, if it pays it off significantly faster it seems worth it to put as much toward the principal as I can.Ive looked online,for a payoff calculator, but all I find calculates a monthly payment, not if I put x amount down with this interest rate it will be payed off in y yearsEdit: interest rate is 4.5 and official loan amount was 77,600  <response>: I chose bi-weekly payments because ive heard it takes 7 years off. 30 year loan, Ive never verified that to be true thoughWhy not? Loan amortization should not be a mystery to a person with a house. Its likely to be the most expensive purchase youll ever make. You should really make sure you understand how your loan works, how the payments work, etc. How much faster will it be payed off by doing Bi weekly payments and an extra hundred.The real question you should be asking is whether or not making the extra payments is better than other potential uses for the money.Start here: Ive looked online,for a payoff calculator, but all I find calculates a monthly payment, not if I put x amount down with this interest rate it will be payed off in y years
