Xirr

Build StatusCoverage StatusCode ClimateDependency Status

This is a gem to calculate XIRR on Bisection Method or Newton Method.

Installation

Add this line to your application's Gemfile:

gem 'xirr', git: 'git@github.com:InfuseGroup/xirr.git', branch: 'master'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install xirr

Usage

include Xirr
cf = Cashflow.new
cf << Transaction.new(-1000, date: '2014-01-01'.to_date)
cf << Transaction.new(-2000, date: '2014-03-01'.to_date)
cf << Transaction.new( 4500, date: '2015-12-01'.to_date)
cf.xirr
# 0.25159694345042327 # [BigDecimal]
flow = []
flow << Transaction.new(-1000, date: '2014-01-01'.to_date)
flow << Transaction.new(-2000, date: '2014-03-01'.to_date)
flow << Transaction.new( 4500, date: '2015-12-01'.to_date)
cf = Cashflow.new flow: flow
cf.xirr

Configuration

# intializer/xirr.rb
Xirr.configure do |config|
config.eps = '1.0e-12'
config.days_in_year = 365.25
