With the growing popularity of second mortgages to finance home improvements, we're offering you the chance to use our blended rate mortgage calculator to figure out the blended interest rate on a combined financing arrangement. The calculator not only provides the blended interest rate, but the monthly payment amount for each loan and the blended mortgage payment.
Calculator Definitions
The variables used in our online calculator are defined in detail below, including how to interpret the results.
The total amount of money borrowed for the first mortgage you have on your home. This is also referred to as the principal of the loan.
Annual Interest Rate - Loan 1 (%)
This is the annual interest rate on your first mortgage. This is not the APR, which takes into account other costs associated with the mortgage.
Term of Loan 1 (Years)
The term of the loan is the number of years over which the first mortgage will be paid. The most common mortgage terms are 15, 20 and 30 years.
Mortgage Amount Loan 2 ($)
This is the mortgage amount you are considering for a second mortgage or loan.
Annual Interest Rate - Loan 2 (%)
Once again, this is the annual interest rate available to you on a second mortgage or loan.
Term of Loan 2 (Years)
This is the term of the second loan, which may be different than the original mortgage.
Monthly Mortgage Payment ($ / Month)
This is the monthly mortgage payment for each of the first and second mortgages. This does not including mortgage insurance or property taxes, which are sometimes included with your mortgage payment.
Blended Monthly Mortgage ($ / Month)
This is the blended mortgage amount you would be paying under a blended financing arrangement. It is the simple addition of the first and second mortgages.
Blended Interest Rate (%)
The blended interest rate is a calculated using a weighted average technique. This value is the average interest rate you would be paying during the time you are paying off both the first and second mortgages.
