Find Interest Rate, Given Principal, Total Interest, and the Number of Periods

'Morning!

I'm kind of blanking at the moment and hoping for some help. I have to find what the interest rate was on certain payments, and have the following info:

Principal: 28,000
Interest Paid: 4,637
Periods: 60

I'm familiar with =pmt() and a couple other payment functions, but just can't seem to figure out how to solve this. Any help is greatly appreciated as always. Thank you!

YES! Yes it would be. I was forgetting to divide the total payment by the 60 periods. It's been a long morning.

Thank you kindly, sir! (or ma'am)
