Compound Interest Quarterly In the last section, we learn how to calculate the CI for half-yearly or semi-annually, in the continuation let us learn the formula on a quarterly basis. Similar to half-yearly; the rate of interest r in the quarterly format is divided by 4 and the time is...
The compounding frequency makes a difference. All other factors being equal, more frequent compounding leads to faster growth. For instance, the table below shows the growth of $10,000 at 8% interest compounded at several frequencies: $10,000 invested at 8% interest compounded...
