Ask google. Sorrry. Hope you will find the answer.( I know I’m not helpful)
The interest rate is the amount of the interest expressed as a
percentage of the principal. Thus, if someone lends you $100 and you
agree to repay him $110 a year later, the interest rate is 10%, which
equals the interest divided by the principal, or ($110-$100)/$100.
