Car Buying Calculator to Calculate Car Buying Comparisons

Car Buying Calculator Sign

Normally, comparing one car buying scenario with other scenarios is extremely difficult since each comes with its own unique price, insurance costs, financing terms, MPG rating, and so on. That is, until you discovered this calculator.

This total car cost calculator will not only calculate the annual, monthly, and per mile cost of buying, owning, and operating an automobile, but it will also allow you to calculate those costs side-by-side with a second car buying scenario.

Plus, unlike other car buying and car financing calculators, this calculator will also calculate the number of hours you will need to allocate to working in order to stay current with the costs of ownership (I hope you enjoy your work).

And finally, once you have calculated the purchase and ownership costs for one or two buying scenarios, the calculator includes a printer friendly report that you can print out and use to compare with numerous other buying scenarios.

Since sellers of automobiles typically only disclose the upfront costs of buying a vehicle, you will likely be shocked at how much it costs to own and operate a motor vehicle if you account for all of the expenses that come attached to the purchase.

The out-the-door (OTD) car price is only the tip of the car cost iceberg.

Price Only Tip of Total Car Cost Iceberg

When you are looking to buy a car do you only consider the monthly payment when deciding whether or not you can afford to purchase the car? If so, then your "personal finance" luxury liner stands a good chance of meeting the same fate as the Titanic.

The moment you sign on the dotted line of an automobile title, you immediately obligate yourself to a host of costs that come attached to the price tag. Let's briefly discuss each cost before we use the car buying calculator to expose and size up the costs that are located beneath the surface of an auto purchase.

Tax, Fees, License, Extended Warranty Costs

In addition to the purchase price of the car, you can also expect to be charged sales tax (if applicable) as well as your initial title transfer and license fees. Sadly, many people simply add these costs to the financing package, meaning they will be paying interest on these upfront fees for years to come.

Depreciation Costs

This is the most important, yet most overlooked and least understood of all costs associated to buying and owning a vehicle -- or any other depreciable asset for that matter.

In case you don't know what "depreciation" is, depreciation can be defined as the amount by which an asset wears out (or progresses toward becoming obsolete) for a given period of time.

Or to put it another way, depreciation is the drop in resale value (what you can sell the asset for) for a given period of time. Typically an asset depreciates at a faster rate when it's newer, and at a slower rate as it becomes older.

As it relates to an auto purchase, the value of the monthly depreciation of a vehicle is equal to the amount you should be setting aside in order to replace the vehicle once it has reached the end of its useful life.

If you're not setting aside a vehicle's depreciation as it occurs (which is over above any auto loan payment you're already making), guess what you will have to do when it's time to replace the vehicle? Yep, you're going to have to continue to pad the huge bonus checks being paid to the lending institution executives.

But wait! It's not enough to know what depreciation is, you must also understand the difference between two types of depreciation. In addition to normal depreciation that occurs as an asset wears out or becomes obsolete, there is also a type of depreciation I refer to as Warp Speed Depreciation.

Warp speed depreciation is the type of depreciation that occurs the moment something goes from being "new" to being "used." The instant you sign the papers to become the proud owner of a brand new car, the brand new car becomes a "used" car and the resale value plummets by as much as 20% of the purchase price!

This means that the absolute worst thing you can do is to buy a brand new vehicle every 1-2 years. That's because your average annual cost of depreciation will likely run in the 20% range, whereas buying a new car every ten years, or a two-year-old car every two years, may lower your average annual cost of depreciation to under 10%.

If you want to see for yourself just how drastic of an effect depreciation can have on your potential future wealth, be sure to experiment with various new and used car buying scenarios using the Car Depreciation Calculator.

Finance Costs

If you finance a car purchase, you will increase the cost of the car by the amount of the interest charges and loan fees that will be tacked on to the principal borrowed.

Insurance Costs

Of course you will also need to make insurance premiums on your car. Typically the more expensive and more sporty the car, the higher your insurance premiums will be. Even higher if you are forced to purchase full coverage in order to qualify for financing.

Fuel Costs

The more you drive your car, the more it will cost you to fuel the vehicle. If you want to calculate MPG and compare car gas mileage expenses, be sure to try out the Fuel Mileage Calculator.

Maintenance & Repair Costs

On average you can expect to pay 3% of the purchase price per year to repair and maintain your car (less in early years, more in later later years). If you do the repairs and maintenance yourself, the cost would be what your time is worth if you had instead used that time to earn an income.

Storage Costs

If you park your car in a garage, any utilities attributable to the garage -- along with the depreciation of the garage structure and fixtures -- is all part of the cost of owning the automobile.

Ownership Cost Meter Needed

Everything you own that can wear out or become obsolete, is doing so at this very moment. If it were possible to install a cost of ownership meter on your life, you would be shocked at how much value the whole of your possessions loses on a daily basis. Unfortunately these costs accrue without a meter to track them, and often only come into light as each asset needs replacing.

When it comes to buying and owning assets that wear out or become obsolete, the bottom line is that if you are not setting aside money to replace these items as they wear out, your financial net worth is likely losing ground, not gaining ground.

Finally, once you become fully aware of the costs associated to buying and owning depreciable assets, you also need to realize that in order to pay for these costs, you must trade free time for work time. In other words ...

The more things you own, the more the things you own ... OWN YOU!

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.
