Mortgage affordability calculator

Find out how much house you can afford before you apply for a mortgage.

Use the calculator to get an idea of how much you can borrow and what your monthly or biweekly repayments would be depending on the loan term you choose. You can change the fields as many times as you want and recalculate to find out how much different mortgage amounts and types will cost.

How to use the calculator

  1. Enter your loan details, including down payment, loan term and your estimated interest rate.
  2. Next, enter your monthly income. This includes your monthly wages as well as any other sources of income, like alimony, Social Security or investment property income.
  3. The last step is to enter your monthly expenses. Include any car payments, credit card payments, alimony or child support or other forms of debt.
  4. Click Calculate to learn how much home you can afford.

Why is it important to use a borrowing power calculator?

Although the final decision of how much you can borrow lies with your lending bank, a borrowing power calculator can be a great starting point to help you figure out how much you can afford, what loan term works best for you and how adjusting your debts or expenses can affect how much mortgage you can afford.

Knowing how much you can afford ahead of time can also help you get started house hunting early and come up with a mortgage proposal that stands a good chance of being approved.

Other costs to consider

The calculator results don’t include property taxes or homeowners insurance. These costs will vary based on your home’s cost, condition and location. If you’re putting down less than 20% of the home’s value, you may also need to pay for private mortgage insurance (PMI). PMI can be eliminated once you have at least 20% equity in the home.

What determines my borrowing power?

Your borrowing power is determined based on several factors, including:

  • Your income. Your income is the biggest factor in determining what you can borrow since it helps determine your ability to repay the mortgage.
  • Expense details. Some lenders will deduct your monthly expenses from your income when determining how much you can afford. Others may use a standardized formula to predict what percentage of your income you can spend on a mortgage.
  • Debt-to-income (DTI) ratio. Your DTI is your total monthly debt payments divided by your income. If you have a lot of consumer debt — credit card debt, for example — pay off as much as you can since this debt could have a bearing on whether or not you get approved.
  • Loan term. A longer loan term cuts down on your monthly installments but increases the amount you have to pay in interest over the life of the loan. A shorter loan term means you save on interest but have to commit to higher monthly payments.
  • Interest rate. Get a competitive interest rate by improving your credit and comparing mortgage lenders.

How do I estimate an affordable property price?

Once you have an idea of how much you can afford monthly, you’re on step closer to knowing the properties you should focus on. Tapping the experience of a real estate professional, like an agent or broker, can further help you narrow down a realistic price range.

Most online real estate sites include mortgage loan calculators that adjust your potential monthly loan repayment based on a property’s price, how much you’re putting down, the rates and terms you can reasonably expect and taxes.

Bottom line

Calculating how much mortgage you can afford can help you shop for a house in your budget and get approved by the lender you want. If you’re not sure which lender offers the best deal for your finances, compare mortgage lenders to find your best fit.
