Question

The Smiths took out a $130,000, 30-year mortgage at an APR of 6.5%. The monthly payment was $821.69. What will be their total interest charges after 30 year?

Answer 1

Total Payments = ($821.69 per month)*(12 months per year)*(30 years)

 

Interest Paid = Total Payments - Initial Loan Amount
