Find the internal rate of return for an investment of $10,000 that returns the following nonperiodic cash flow. The original investment is the first cash flow and is a negative number.

Cash Flow Dates

-10000 12-Jan-2007

2500 14-Feb-2008

2000 03-Mar-2008

3000 14-Jun-2008

4000 01-Dec-2008

Calculate the internal rate of return for this nonperiodic cash flow:

CashFlow = [-10000, 2500, 2000, 3000, 4000];
CashFlowDates = ['01/12/2007'
                 '02/14/2008'
                 '03/03/2008'
                 '06/14/2008'
                 '12/01/2008'];
Return = xirr(CashFlow, CashFlowDates)
Return = 0.1006

Alternatively, you can use datetime input to calculate the internal rate of return for this nonperiodic cash flow:

CashFlow = [-10000, 2500, 2000, 3000, 4000];
CashFlowDates = ['01/12/2007'
                 '02/14/2008'
                 '03/03/2008'
                 '06/14/2008'
                 '12/01/2008'];
CashFlowDates = datetime(CashFlowDates,'Locale','en_US')';
Return = xirr(CashFlow, CashFlowDates)
Return = 0.1006

Input Arguments

collapse all

Cash flow, specified as a vector or matrix. The first entry is the initial investment. If CashFlow is a matrix, each column represents a separate stream of cash flows whose internal rate of return is calculated. The first cash flow of each stream is the initial investment, usually entered as a negative number.

Data Types: double

Cash flow dates, specified as a vector or matrix of serial date numbers, cell array of date character vectors, or datetime arrays. The size of the input date numbers for CashFlowDates must the same size as CashFlow. Each column of CashFlowDate represents the dates of the corresponding column of CashFlow.

Data Types: double | char | datetime | cell

(Optional) Initial estimate of the internal rate of return, specified as a scalar or vector. If Guess is a scalar, then it is applied to all streams, and if Guess is a vector, then it is the same length as the number of streams.

Data Types: double

(Optional) Number of iterations used by Newton's method to solve the internal rate of return, specified as a scalar or vector of positive integers. If MaxIterations is a scalar, then it is applied to all streams, and if MaxIterations is a vector, then it is the same length as the number of streams.

Data Types: double

(Optional) Day-count basis, specified as a positive integer using scalar or a N-by-1 vector. If Basis is a scalar, then it is applied to all streams, and if Basis is a vector, then it is the same length as the number of streams.

Annualized internal rate of return of each cash flow stream, returned as a vector. A NaN indicates that a solution was not found.
