Mortgage Debt Avalanche Calculator

[James Bausch]

I know I'll get "beat up" here on BP for even suggesting paying everything off :) but I'm at the point where I'm ready to stop scaling (for now) and have everything paid off.

I'm really struggling to find an Avalanche Debt Payoff Calculator for mortgages.
Everything I find is just for general consumer debt.  Am I wrong to think that I need a mortgage calculator due to amortization schedules?
Where can I find a calculator for this?
