Final answer:
Javier and Anita Sanchez's after-tax cost of the interest expense on their home loan in 2023 is $23,228.80. This is calculated by deducting their tax savings from the total interest payment which is influenced by their 32% marginal tax rate.
Step-by-step explanation:
The after-tax cost of the interest expense to Javier and Anita Sanchez for their home purchased on January 1, 2023, can be calculated as follows:
- The total annual interest payment without taxes is the loan amount multiplied by the interest rate, which is $488,000 multiplied by 7%, equaling $34,160 per year.
- To find the after-tax cost, we reduce the interest payment by their marginal tax rate, which is 32%. So, the tax savings from the interest deduction is $34,160 multiplied by 32%, which equals $10,931.20.
- Subtracting tax savings from the annual interest payment, the after-tax cost is $34,160 - $10,931.20, which equals $23,228.80.
Thus, the after-tax cost of the interest expense for the year 2023 for the Sanchezes is $23,228.80.
