Calc - Rate Function similar to Excel

Hi Johnny,

My apologizes for not being clearer.

I've never used Rate Function in Excel nor Calc.

I've explored the ? Help function but that's not altogether clear for me.

I'm trying to figure out the step-by-step of calculating the interest rate
(not total interest amount charged for the length of the loan) on a car
loan where $11,886.87 is borrowed and the monthly payments are $291.09 a
month for 48 months.

I open Calc and then where do I find Rate Function?

Once that feature is activated, how/where do I input the factors I have to
have it calculate the interest rate?

Thank you for your help.

Charles.
