This might be more of a math question, but anyways. I'm trying to find the overpayment percentage of the initial mortgage, but want to make sure my calculation is correct.

If....

Your annual interest rate is: 10%

Your initial mortgage amount is: $20,000.00

Your monthly payment is: $193.00

Your total payment over 20 years is: $46,321.04

Your overpayment is: $26,321.04

Your overpayment percentage of initial mortgage is: 43.18%
