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

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!

Embed individual charts in your articles, for free!

Full calculators might not be ideal to embed. Sometimes you just want to embed an individual chart to make a point.

Styling, Currency, Locale

I know you aren’t all in the UK, and you don’t all pay for everything in good old British Sterling. You also might not like Money Mages’ steelblue. So Money Mages’ calculators are completely customisable.

For charts, you change the colours, the locale, and the currency. This lets you match your brand, and use the right date format and currency!

For calculators, the HTML you need to add can be completely laid out and styled as you please. By default, the styling is basic. But with some simple CSS you can match your brand and site style easily!
