ClojureWerkz Money is a tiny Clojure library for working with money and currencies. It is built on top of Joda Money. Money is small, easy to use, integrates with Monger and Cheshire.

Money, Money, Money

Many ClojureWerkz projects take advantage of existing mature JVM libraries. Today we introduce another library to this club: Money. Money is a very thin layer on top of Joda Money, an excellent money library from the creator of Joda Time.

What’s In The Box

  • Operations on monetary amounts (add, substract, multiply, divide, negate, etc)
  • Conversion between currencies
  • Support for multiple rounding modes
  • Parsing of strings (e.g. USD 20)
  • Currency unit looks by ISO-4217 code and country
  • Cheshire integration
  • Monger integration


Money is a small library and all of its documentation guide fits in the README.

Supported Clojure Versions

Money supports Clojure 1.4+.
