How can I make more payments by making biweekly payments?

Yes, if you make biweekly payments, that is, making payment every 2 weeks, then all total in a year you will make 13 payments. Because, there are 52 weeks in a year, and bi weekly payments mean 26 half payments.
So, instead of making 12 payments in a year, it will become 13 payments in a year. It will help you to repay a loan early.

Making biweekly payments will help you to pay off your debt faster. Mabelle Page has explained correctly why biweekly payments are better than monthly payments!
However, opt for biweekly payments if you are having a steady income. Otherwise, missing payments can increase your debt burden!
