## How much home can I afford?

When buying a home, one of the most crucial steps 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 a questions that bothers many people: **"how much home can I afford?"** or **"what house can I afford?"**.

A general rule of a thumb says that 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 total debt of the borrower 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 a very good 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 the **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 you input the last field, the home affordability calculator will immediately show you your results. The **maximum loan** is the maximum value of 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, RV loan). You can also switch to yearly debt. **Homeowner insurance**β 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, although 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 are willing to put down as a
**down payment**. - Your
**current income**and**current debts**β 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**β 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 like 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.
