House Affordability Calculator to Calculate a Realistic Home Price

House Affordability Calculator Sign

The free online calculator will calculate the price of the home you can afford based on the amount of cash you have available for a down payment and on the monthly funds available for paying your mortgage payment and ongoing costs of ownership.

Unlike other online home affordability calculators that tell you how much house you can afford based solely on the monthly mortgage payment, this calculator includes an estimate of the monthly homeownership costs that will greatly impact how much house you can truly afford.

If you are only interested in finding out the size of the mortgage you might qualify for, please visit the Mortgage Prequalification Calculator.

Or, if you would like to compare buying a home versus renting a home or an apartment, please visit the Rent Vs Buy Calculator -- which includes other home affordability factors you need to consider.

Beware of the hidden costs of home ownership.

Should you believe a commissioned real estate agent or mortgage broker when they tell you how much house you can afford?


That is, not unless you're on a mission to increase their financial happiness at the expense of yours.

No matter what they tell you, the goal of every real estate agent and mortgage broker is to get you to buy the home that pays them the highest return for their efforts.

And unless these vested sellers happen to be your loving parents or close personal friends, they really could care less if ten years from now you are forced to sell your home at a loss because you couldn't afford to keep up with the mortgage payments and all of the hidden costs of ownership they failed to warn you about.

Income Level Has Nothing To Do With Affordability

No matter what your income level, if your annual non-home related expenses meet or exceed your take-home pay, then you can't afford to purchase and maintain a home.

The only number that matters when determining how much house you can afford is the difference between how much you take home and how much you spend on non-home related expenses.

If you don't know how much that difference is, be sure to visit the personal budgeting calculator to get a realistic affordability number to work with.

Beware of Hidden Costs of Home Ownership

Contrary to what some real estate agents and mortgage brokers will attempt to get you to believe, just because you can afford to make the prescribed monthly principal and interest mortgage payment does not necessarily mean you can afford to purchase and own the house in question.

That's because there are many other costs that come with owning a house that are above and beyond the monthly payment. These include:

  • Private Mortgage Insurance (PMI)
  • Property taxes
  • Homeowner insurance
  • Utilities
  • Maintenance costs

Did Your Real Estate Agent Tell You This?

According to an American Housing Survey (AHS) conducted by the Census Bureau in 2003, the average annual cost to maintain and operate a house at that time was $5,464, with 38% of that amount going for taxes, 40% for utilities, 12% for insurance, and 10% for maintenance.

Using the CPI Calculator to adjust for inflation between 2003 and 2018, that $5,464 has likely grown to $7,470. And if you divide that by 12 months ...

That's roughly $622 per month just for home ownership costs.

I believe the reported maintenance figures are actually lower than they should be based on hearing numerous real estate agents report that most homeowners are failing to properly maintain their homes.

Ignored Ownership Costs Lead to Falling Home Values

In my opinion, homeowners failing to properly maintain their homes is a result of purchasing more house than they could afford.

After all, if you buy more house than you can afford, then all of your available funds will be going toward meeting the minimum obligations to keep your house -- leaving little if any funds for home maintenance and repairs.

Of course, if you can't afford to properly maintain the house you are buying, then your house may actually fall in value (depreciate) over time.

Or, even if you are properly maintaining your house, but your neighbors are not, then your house's value might fall in spite of your best efforts -- because now it sits in a run-down neighborhood with falling property values.

Ignorance Is Bliss ... For a While

The bottom line is this.

If you buy a home-based on what self-serving sellers say you can afford -- without carefully factoring in the homeownership costs -- then sure, you may be able to afford to make the payments for a few years.

However, as the mechanical and material parts of your home begin to wear out and need replacement, you will likely come to regret taking the sellers at their word.

Free Home May Be Too Costly

Due to the ignorance of homeownership costs and wrongfully assuming that their income levels would last forever, turns out that many homebuyers couldn't afford their homes even if someone had given it to them for free.

Of course, no one can predict what will happen with your future income.

So what can you do to protect your home from economic downturns besides adding another insurance premium to your budget?

The best way I know of to protect your home from the next time the greedy financial giants decide to fatten themselves up by eating their own children, is to adopt the Grow Slow, Pay As You Go Method of Home Buying.

Adjust Calculator Width:

Move the slider to left and right to adjust the calculator width. Note that the Help and Tools panel will be hidden when the calculator is too wide to fit both on the screen. Moving the slider to the left will bring the instructions and tools panel back into view.

Also note that some calculators will reformat to accommodate the screen size as you make the calculator wider or narrower. If the calculator is narrow, columns of entry rows will be converted to a vertical entry form, whereas a wider calculator will display columns of entry rows, and the entry fields will be smaller in size ... since they will not need to be "thumb friendly".

Show/Hide Popup Keypads:

Select Show or Hide to show or hide the popup keypad icons located next to numeric entry fields. These are generally only needed for mobile devices that don't have decimal points in their numeric keypads. So if you are on a desktop, you may find the calculator to be more user-friendly and less cluttered without them.

Stick/Unstick Tools:

Select Stick or Unstick to stick or unstick the help and tools panel. Selecting "Stick" will keep the panel in view while scrolling the calculator vertically. If you find that annoying, select "Unstick" to keep the panel in a stationary position.

If the tools panel becomes "Unstuck" on its own, try clicking "Unstick" and then "Stick" to re-stick the panel.
