Anyone mind helping me to work this out?

I am currently servicing progressive payments on my property (first payment will be due on the 1st of next month). To date RM80,943 has been disbursed to the developer. If the interest rate on my house loan is 4.45% p.a. on daily rest, how much would I save by taking the EzyCash 0% promotion for RM6000 and dumping it into my loan account? So far I have computed that at 3.88% + GST for the admin fee, it should cost me RM246.77 to take the loan (approximately RM41.13 monthly).
