One of the nice things about a mortgage is the interest charges are deductible from your federal income taxes. If you want to know just how much you can deduct, then try our mortgage tax deduction calculator. It provides you with the total interest charges / tax deductions as well as the tax benefit over the life of a mortgage. The calculator also provides an amortization table, which provides the tax deduction by year.
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 this mortgage, also referred to as the principal of the loan.
This is the annual interest rate on the mortgage. This is not the APR, which takes into account other costs associated with the mortgage.
The term of the loan is the number of years over which the mortgage will be repaid. The most common mortgage terms are 15, 20, and 30 years.
This is your incremental federal tax rate, sometimes referred to as your tax bracket. This value will be used to compute the total tax benefit derived from the mortgage.
This is the monthly mortgage payment for the loan itself. This does not include mortgage insurance or property taxes, which are sometimes included with your mortgage payment.
The total amount paid to the bank or lending institution over the life of the mortgage. The value is derived by multiplying the monthly payment times the number of months over which the mortgage is outstanding.
The total interest paid on the loan is the difference between the total payments and the total home loan amount (the cost of borrowing the money). It is these interest charges that you will be allowed to deduct from your federal income taxes.
The total tax benefit is determined by multiplying the total interest paid times your incremental federal tax rate. Since you are allowed to deduct interest charges from your federal income taxes, this value will be the net savings, or benefit, you gain from this deduction. The value computed is the total benefit over the life of the mortgage.
The tax benefit table provides you with an annual look at the potential tax deductions you'll have each year. This calculator also provides you with an amortization table, showing the decrease in the mortgage's principal over time.
