My friend told me if I pay fortnightly I can reduce my homeloan many thousands more per year than compared with monthly payment, since the principle gets reduced faster. Is that true?
Your friend is over-estimating a bit but if you're paying principal & interest, fortnightly or weekly payments do make a small difference.
Fortnighly payments are calculated by taking the monthly P&I payment and dividing it by two. The reason you get ahead with this method is because there are 26 fortnights in a year, not 24. Each year you effectively make one months extra payment. Whilst this does equate to 'thousands', some people are under the impression it'll reduce their home loan by 10 or more years.
Over a 30 year loan, this will save you about 3 years in repayments.
If you have an offset account and have your salary paid there, the effectiveness of forntighly payments is almost negligible because the balance in the offset acts like an extra repayment anyway. This is usually more effective.
For the most part, I suggest people match their payment cycle to their paypacket or budget cycle. It makes money management easer.
Here's the silver bullet for reducing your home loan quickly...
Make extra payments as often as possible.
