goxirr

Goxirr is a simple implementation of a function for calculating the Internal Rate of Return for irregular cash flow (XIRR).

Example

import "time"

import "github.com/maksim77/goxirr"

firstDate := time.Date(2019, time.January, 1, 0, 0, 0, 0, time.UTC)
t1 := goxirr.Transaction{
	Date: firstDate,
	Cash: -100,
}
t2 := goxirr.Transaction{
    Date: firstDate.Add(time.Hour * 24 * 365),
    Cash: 112,
}

tas := goxirr.Transactions{t1, t2}
fmt.Println(goxirr.Xirr(tas))
