The fully free and open source full-stack Car Costs Calculator for more than 30 countries
This calculator gives users a good estimate of what they really need to spend on car ownership. As car payments and expenses come due throughout the year, it's often difficult to really get a good understanding of total spending on a car.
This calculator also provides to the user, optionally, the car's full Financial Effort considering the user's income, further providing also optionally the equivalent public transport costs (bus, train, UBER, etc.), considering the user doesn't own a car.
git clone https://github.com/jfoclpf/autocosts.gitcd autocosts && npm ci --omit=devnpm startit will open a http local server which you can access through http://localhost:3028
The translations are in corresponding json files, namely in the folder src/countries/.
The list of available countries is from the file src/countries/list.json

Autocosts uses nodejs, expressjs and handlebarsjs to supply a server application that renders a car costs calculator as a webpage loaded by any common browser.
The project is optimized for a web-based version, and for an APP developped in Apache Cordova. The 2 last letters on the URI stands for the 2-letter ISO country code, and not for the language, since for example United Kingdom and Australia have the same language but different realities concerning the taxes, the terms applied to automobile costs and the units for fuel efficiency. The translations/language files apply therefore only to the selected country.
The project already considers all the units and fuel efficiency cases, different in many countries. The variations for fuel efficiency are L/100km, km/L, mpg(US), mpg(imp) and for distance are km, miles and mil (Nordic mile=10km). More information can be found in the directory src/countries/.
For more information regarding how the costs are calculated, you can check the src/client/core/ which is based on the 12 items that form the car costs for any given country. Namely they are:
For more information see contributing.md
Autocosts supports the following additional services, which can be enabled or disabled (default).
After building with node build.js, run node bin/server.js -h for more information.
Autocosts also supports code such that the user inputs might be stored into a mysql database. With the data from said database, it is also possible to make several statisitcal analysis, namely the average costs for each country, said statistical analysis having outlier removal techniques, such that such outliers do not distort the average.
Autocosts may use the UBER API, such that at the final repport, the user calculations can be compared with the equivalents costs if the user would use just UBER or combined with public transports.
Autocosts also allows the final report to be printed into a PDF report. It makes use of pdfmake npm package.
The credentials for the above services are in the JSON files stored in credentials/
The API works normally as any other npm API without the need to install any extra software.
Just install the API
npm i autocosts
Now use the autocosts API

To development and fully build the app one further needs:
ImageMagick (to compress images) andWebdriver Manager npm package to emulate Chrome and Firefox in the test suiteOn Ubuntu/Debian one can run to install and configure them:
sudo apt install imagemagick -y
sudo npm i -g webdriver-manager
sudo webdriver-manager update --out_dir /usr/local/bin
sudo rm /usr/local/bin/*.zip /usr/local/bin/*.tar.gz
sudo mv /usr/local/bin/chromedriver* /usr/local/bin/chromedriver
sudo mv /usr/local/bin/geckodriver* /usr/local/bin/geckodriver
To custom build the app resources into the bin/ directory, use the build.js node script at the root of the project. For more information run node build.js --help.
You have already standard configurations accessible in package.json which you can list by executing npm run.
After having built the app, to custom run it use the bin/server.js node script. For more information run node bin/server.js --help.
See also standard server configurations by executing npm run.
The Android APP can be found in Play Store. It uses Apache Cordova to convert JavaScript built code into APP built files (for example APK files in Android)
