Albert Einstein wrote: “Compound interest is the eighth wonder of the world. He who understands it, earns it ... he who doesn't ... pays it.” Many people do not appreciate the true compound cost of interest over time until they see the numbers side by side.
Not only do interest costs add up over time, but cars also depreciate quickly. A new car may depreciate as much as 10% to 20% the day it is driven off the lot. Buying a rapidly depreciating asset at a high rate of interest discounts your future labor.
"A debt is a lien on future labor; and you derive most of your income from your labor. So, you never, ever want to put a lien on your future labor except for the purpose of investing in an asset that is likely to increase in value over the life of the loan, that is, to exceed to total cost of the principle plus interest on the loan. To do otherwise is to discount the value of your labor." - Eric Janszen
While new cars may instantly lose a lot of value the moment they are driven off the lot, many people buying used cars without first running the numbers & comparing their options can also lose big. Here is a Last Week Tonight video covering some of the shady aspects of subprime auto lending market.
Our calculation tools have helped many car shoppers save money & I love getting feedback from our visitors. Here's one of the many emails readers have sent. :)
I had already done all of my used car research, but I used the comparison feature on your calculator to check the actual, real consequences of each of the loan offers I got. It really helped seeing them lined up in such a clear way. This is my first time financing a vehicle, and actually seeing the reality of those numbers and the differences in tiny little percentage points was enlightening.
I just wanted to let you know that your website is incredibly informative without talking down to anyone or treating your visitor like they are dumb for not knowing how car buying works. Although I had managed to collect most of this information from sources here or there, you've got it all summed up beautifully. I sent your page to my sister and several other people I know who might be looking at financing for the first time in the next couple of years.
Thanks for something so seemingly simple yet so necessary.
If you have found our site helpful or have other feedback, plese feel free to email me at . If you run a blog or website or share stuff on social media sites like Facebook or Twitter please give us a shout out there. :)
I have redesigned this site about 3 or 4 times over the years. On desktop computers the design may look overly simplified, but that is in part because the site has been simplified significantly, as it has been designed primarily to look good on mobile devices & provide a great + fast user experience to people who are out shopping for a car. The vast majority of our website traffic comes from cell phones. Some people who are shopping run the numbers through our site to help verify what the salesman is telling them.
Most the pages on our site are not text-heavy & if we have a significant amount of text on the page we typically try to put it (along with anything else) underneath the calculator, so our visitors can get to calculating their finances straight away. The homepage of our site has a fairly extensive buyer's guide for car shoppers, but we put most of that content behind accordions to keep the page light & make the calculator stand out more.
What is with the lemon icon / favicon? It was an attempt at humor, but also a reminder to check twice and make sure you are spending your hard earned money on a good, reliable vehicle rather than a lemon that will have reliability issues & become a big money sink.
So, this is the page where I tell you a little bit about myself and the site. I'll try to sound as interesting as possible ;)
My name is Sara Morrin, and I live in the Sin City of the South: Atlanta, GA. The idea for this site was started as a school project when I was a Junior in high school. We had an assignment in one of our elective classes. We were to find a free online tool or application to solve a current real-life 'problem' or 'decision', and to explain the details. At the time, I was working part-time as much as I could and saving up for a used car. I knew I would have to get a loan, and the calculation of interest & monthly payments were a primary concern. Every single Dollar from my job would be put towards the car payment, and I needed to pay it off before I finished my Senior year.
This easily served as my 'problem' to solve for my assignment. I used a few online calculators and finished my assignment easily. At the same time, I noticed many calculating features that were missing, which I would have liked to use. I asked my uncle, who is a long-time programmer, about the possibilities of creating these features for a better type of calculator. He advised me that it was certainly possible, and that he would help if I put forth an equal amount of effort. After 6 months of research and collaboration, we completed the site. So here it is - and here you are too!
I'd want to give a special thanks to my uncle for all the help. Thanks Paul!
