How much home can I afford?
One of the most crucial steps when buying a home is setting the right budget. Hardly anybody pays for a home in cash. In fact, most of us must take a loan to finance the purchase. This raises questions that bother many people: "how much home can I afford?" or "what house can I afford?".
A general rule of thumb says that a borrower may get a mortgage when the total household expenses are no more than 28% of their pre-tax income. Note that household expenses are typically referred to as PITI because they include the principal, interest, taxes, and insurance.
The same rule also states that the borrower's total debt should be no more than 36% of their pre-tax income. Due to these two figures, this rule is known as the 28/36 rule. If you want to check how it works, try our 28/36 rule calculator.
Obviously, the 28/36 rule is only a rough approximation. Sometimes the lender may agree to exceed the thresholds set out in this rule; for example, if you have an excellent credit score, you may receive a higher maximum debt-to-income ratio.
However, you should remember that even though you may qualify for the given mortgage amount, it may not be suitable for you. Before taking such a serious commitment, you should carefully review your situation. It is always a good practice to discuss taking a mortgage with a financial advisor who will help you decide how much you can afford to borrow without stretching your personal budget.
How to use our home affordability calculator?
The usage of our house affordability calculator is very simple. All you need to do is fill out the appropriate fields and wait a second for the results.
In simple mode, which is available by default, the calculator works as a mortgage affordability calculator. To perform the calculations, you have to complete only three fields:
Your maximum payment – The maximum amount you can pay each month towards repaying the mortgage (i.e., the money you can afford to spend on housing). It can be expressed on a yearly or monthly basis. Remember that it should be carefully estimated with the 28/36 rule described above.
Loan term – The period over which the mortgage is granted. Usually, it is a long period, often between twenty and thirty years.
Interest rate – The cost of the mortgage expressed in percentage points. Usually, it is an annual interest rate.
After inputting the last field, the home affordability calculator will show you your results immediately. The maximum loan is the highest value of the mortgage you can afford with the given monthly payment.
In advanced mode, the calculator allows you to do more complicated calculations. In the additional information section, you are asked to give information about:
Money you have – The amount of money you can use as a down payment. It's the money you have and are willing to spend on a house (note that there is usually a minimum down payment required by the lender).
Your monthly debt – The installments you need to pay every month on other loans (e.g., auto loan, personal loan, or RV loan). You can also switch to yearly debt.
Homeowner insurance – The price of a standard homeowner policy that covers damages to the property. It can be provided either on a yearly or monthly basis.
Property tax – The tax you have to pay as a property owner. It can be provided either on a yearly or monthly basis.
Closing costs – The total upfront costs that are required when buying a house. This usually varies between 2-5% of the total transaction value.
This time the results section contains two values. The first one is the same as before – the maximum loan you can take. The second one – maximum home value – shows you the maximum value of real estate you can afford.
How to calculate your house affordability?
With our home affordability calculator, estimating how much home you can afford is a piece of cake. However, you may wonder about the equations that this calculator uses to obtain the final result. In this section, we briefly explain to you the ideas that govern our tool.
To estimate how much house you can afford, you need to know a few variables:
The money you have and are willing to put down as a down payment.
Your current income and current debts – income determines your maximum creditworthiness and thus also the maximum amount of mortgage you can take. On the other hand, your current debts diminish your creditworthiness. The bigger your debt, the lower the maximum amount of loan you can take.
Additional household expenses – for example, property taxes and home insurance (as a tenant, you do not have to cover such costs).
You should also take into account additional factors, such as closing costs.
Once you have all of the necessary information, the next step is to compute the maximum amount of mortgage you will be allowed to take. You can do it with the following formula:
Maximum loan = (1 - (1 + Interest rate)-Loan term) × Monthly installment / (Interest rate / 12)
The Monthly installment here is the monthly cost of the mortgage. It cannot exceed your payment ability. To calculate its maximum value, we use the following formula:
Monthly installment = Maximum payment - Insurance - Tax - Current debt
Note that all of the components of this equation (Maximum payment, Insurance, and Tax, and Current debt) should be expressed on a monthly basis.
In the next step, we estimate the Maximum home value. It can be presented in the following way:
Maximum home value = (Maximum loan + Down payment) / (1 + Closing costs)
Maximum loan here is the maximum mortgage value calculated in the first step. Down payment and Closing costs are explained in the previous section.
