<prompt> Human: TIL that the interest on my mortgage is approximately 8 a day. CAIf I understand interest correctly, an extra 250 a month would essentially negate my interest charges.My balance is approximately 86k with 14 years left.Thoughts?Assistant: That isnt how mortgage amortization works. With each payment the portion that is interest decreases while the principal portion increases.Human: If I understand correctly, the principal increases by the amount of interest charged. So if I pay that amount in addition to my normal pay, am I effectively counter-acting the increase?  <response>: No, not at all, do some research on mortgage amortization.
