Never, ever, EVER pay to be able to make bi-weekly payments. I know of one lender out there that charges a $750.00 initial set up fee to withdraw a 1/2 payment out of your checking account every two weeks.

If you are with a lender that would do that, it is actually slightly more to your advantage to forgo the bi-weekly payments and just make an additional monthly payment at the beginning of each year.

Basically, it works like this:

If you were to have a $10,000.00 loan and your monthly payment was $500 per month, your interest accrues daily based on your current balance.

If you only make a single monthly payment, the interest paid will be calculated on having a $10,000.00 balance for 30 days. If you make bi-weekly payments of half that amount, the interest would be calculated on a $10,000.00 balance for 14 days and then based on a $9,750.00 balance the next 14 days, reducing the amount of interst you pay.

Gar1976 already pointed out where most of your savings come from though - in essence, you are making an additional payment each year, simply because of how our calander is set up. If you pay monthly, you make 12 payments per year - if you were paying twice a month, it would equal 24. As there are 52 weeks in a year, paying every two weeks would give you a total of 26 payments - or 13 monthly payments.

I would highly recommend doing this on any installment loan that you have, be it bi-weekly or just an additional payment every year. Basically, the more often you pay the greater your savings - however, the savings, especially on shorter term loans, can be negligible. When I worked at a credit union we had a fellow there that divided his monthly payment up into how much he needed to transfer a day. Every day, without fail, he would come in and transfer the $2.38 from his savings account to his car loan to maximize his savings....
