Personal Finance Education is lacking. Fruggles everywhere are suffering from lifestyle creep. I am passionate about improving basic knowledge of Personal Finance.

Personal Finance Calculators

That’s why I’ve built a set of free Personal Finance Calculators. They provide straight-talking, information-only facts. No selling of products or affiliate pushing.

You can try out the calculators right away:

From today, you also embed the full calculators or even the individual charts on your Blog or Website. For free!

It’s so simple, just add a couple of lines of HTML. There are examples and snippets you can just copy & paste. I am here to help get you started if you get stuck! I’m a software engineer by trade, so just get in touch if you need a hand.

Now you can! You can use the charts. There are currently three charts:
