The credit card interest calculator

A Piggybanker service

About Piggybanker

Piggybanker is an easy to use credit card comparison service to help people make clever decisions without having to spend hours on research.

We’re totally independent so we provide you with the key details about the different credit cards from all major providers. We also got rid of the financial jargon to make things simple and easy to understand. Check out our FAQs section to learn about what the different financial terms mean.

Piggybanker is also completely free. All we ask is that if you like it, tell your friends (if you didn’t, send us an email and tell us how we can improve).
