How to Use the Calculator

Based on Income

To calculate your mortgage qualification based on your income, simply plug in your current income, monthly debt payments and down payment, as well as the term and interest rate on your home loan. Then choose whether you'd like to take taxes, insurance and HOA payments into account.

Based on Monthly Payments

How much home you can afford can also be calculated by setting how much you can pay monthly. To calculate this way, switch the calculator from income to payment. Then, input your maximum payment, down payment, term and interest rate.
