Fuel savings vs total cost calculator
Hi,
If anybody's interested, I wrote a calculator to compare cost of ownership between two cars with different initial costs & fuel efficiency: https://sporkforge.com/finance/gas_cost.php It also does time discounting of future costs. |
Interesting. Thanks for it. I tried comparing the newer cars I am looking at to just my car, and the break even point is 10+ years.
only driving 468 miles (750 km) per month and $6 for gas should even it out, but even the cheapest car and the car I want break even in almost 3 years. |

Sporkman: Thanks a lot for the calculator tool that you wrote. An excellent first post! Most people come here asking for help, but you jumped on and immediately starting helping! A warm welcome to you, my friend! Get a gaslog started and get ready to save gas!
Do you have any plans on adding more variables to your formulas? Perhaps allowing users to look at electric car costs? I tried entering a negative value, and the program still worked, so that was good. Whether my thinking on this is correct or not could be debated, I think that entering a negative value is a good test. Let's say you have a car worth $4000. Holding on to that car, you have possession of something worth $4000. Selling it would get you $4000... and while typing this I realized my error. If you already own your vehicle, and you are considering just sticking it out in the vehicle you already own, it wouldn't make sense to use a negative number. You would just use 0 for cost. I just ran a situation where I would a) keep my 1998 Jetta TDi, or get a new Polo TDi -- if they are ever released in America. The calculations ran off the charts. Do you have any plans to extend the timescale past 10 years? It probably wouldn't make sense for a purchase decision, but it would be neat to be able to see the math worked out. Not many people keep a main car for 20 years but.... |
Very cool little app. Welcome to GS

I capped it at 10 years because (a) that's a practical time horizon, (b) to save on runtime, as I use a simple linear search for the breakeven point, and (c) to keep the yearly cost summary to about a page width... |

Great job on the calculator!!
I just realized that if i rode my bike to work for a year and saved my gas money, i could buy a new car, well used really. Ok maybe thats exagerating a little but i really have to get a car thats better on gas. |
Bookmarked!
Thanks! |
GOOD JOB! Nice - Thanks!:thumbup:
