need link to mortgage payoff calculator? can't find one that works?

[gardensallday]

I am near the end of my mortgage, and all the mortgage calculators I can find are for people at the BEGINNING of their mortgage. I want one where I can enter the balance left on the mortgage and the interest rate and the fact the payments are once a month, and that should be all the data needed.

can someone save me from having to figure out how to use a spreadsheet again or doing this by hand?

thanks!

Ps if you don't understand what I am asking, don't answer, because there are many mortgage calculators that do not work for my needs.
No, the bankrate calculator will not work, it doesn't ask what balance is left on my mortgage. I have consistently paid more than the minimum.

If you have made extra payments of varying amounts, NO online calculator will account for them.
If you use Microsoft Excel, there is a FREE downloadable template for a loan calculator with extra payments. All you need to enter is the original terms, and the amounts of the extra payments.

Below is a link that might help. It's intended as a way to prioritize multiple debts, but you can just enter the one: current balance, interest rate, monthly payment. On the second tab, there's a spot to enter additional payments going forward. Just like any other calculator, it will not be exact so check with your lender before making a final payment, but hopefully it will help
