# How would I found the compound for the following on each account with compound interest?

Determine how much is in each account on the basis of the indicated compounding after the specified years have passed; P is the initial principal, and r is the annual rate given as a percent. After one year where P = $4700 and r = 2.5% Find the compound quarterly, monthly, weekly, and daily. I found the compound annually ($4817.5) but I'm not sure what the formula would be for them. If you can explain, that would be great!

For shorter compounding periods, you compute each period with the applicable interest. For monthly compounding you get $\frac {2.5\%}{12}$ interest each month, so at the end you would have $4700(1+\frac {2.5\%}{12})^{12}$. Compounding means you earn interest each period on the total in the account including interest earned previously.
