Newbie Joined: May 2015 From: US Posts: 1 Thanks: 0  Weekly interest compounded Monthly
I have gone blank, please help: A loan attracts interest at 1.25% per week, compounded monthly. What is the effective interest rate per annum taking into account the compounding effect? Whats the Excel Function that does this? Thanks!!

1.25% per week means 52 * 1.25 = 65% : improbable. Please provide an example showing when payments are made, and when interest is added to the principal.
