As stated above , making extra payments is wrong , you make a payment and also enclose a check and a note stating you are making a " payment on the principal " also .

I don't write checks or send notes to my bank. My online bank has a place to categorize payments, "Regular payment", "Principal payment" etc. I asked a simple question. I thought. Notes and checks get lost in the mail. Haven't you heard?

DownTheAvenue made it sound like it might be more complicated than that.
