Mortgage payment frequency can deceive- explained in beer math.

Most are "sold" on weekly or bi-weekly payments because it will save money.  Thousands are saved just by dividing the payment in quarter (weekly) or half (bi-weekly) and paying more often.  There are 52 weeks in the year, or 26 bi-weekly payments in the year.

What they do not always tell you is by the end of the year, you will have made 13 monthly payments, not 12.  It is the paying of 13 monthly payments within the year that brings down your balance and interest costs.

It is not because you have paid more frequently.  So, the question for you is- did you plan to pay MORE towards your mortgage?   And, if you paid more elsewhere (tax deferred plans, higher interest cost debt reduction, liquid savings for emergency, budgetted funds for auto replacement, etc) would you gain more value putting your money towards something other than the mortgage?
