Fortnightly Repayment Calculator 

When making loan repayments, you can pay either monthly, fortnightly or weekly. This calculator demonstrates how much interest you can save over the life of your loan but also how it reduces the time it will take you to repay your loan, by changing to fortnightly or weekly repayments.
With monthly payments you make 12 payments, and some banks calculate your fortnightly repayments by halving the monthly payment. You then have 26 repayments, which is 13 months worth of repayments, so you end up paying an extra month off the loan!
