# fvvar

Future value of varying cash flow

## Syntax

```FutureVal = fvvar(CashFlow, Rate, CFDates)
```

## Arguments

 CashFlow A vector of varying cash flows. Include the initial investment as the initial cash flow value (a negative number). Rate Periodic interest rate. Enter as a decimal fraction. CFDates (Optional) For irregular (nonperiodic) cash flows, a vector of dates on which the cash flows occur. Enter dates as serial date numbers or date strings. Default assumes CashFlow contains regular (periodic) cash flows.

## Description

FutureVal = fvvar(CashFlow, Rate, CFDates) returns the future value of a varying cash flow.

## Examples

This cash flow represents the yearly income from an initial investment of \$10,000. The annual interest rate is 8%.

 Year 1 \$2000 Year 2 \$1500 Year 3 \$3000 Year 4 \$3800 Year 5 \$5000

For the future value of this regular (periodic) cash flow

```FutureVal = fvvar([-10000 2000 1500 3000 3800 5000], 0.08)
```

returns

```FutureVal =

2520.47
```

An investment of \$10,000 returns this irregular cash flow. The original investment and its date are included. The periodic interest rate is 9%.

To calculate the future value of this irregular (nonperiodic) cash flow

```CashFlow = [-10000, 2500, 2000, 3000, 4000];

CFDates = ['01/12/2000'
'02/14/2001'
'03/03/2001'
'06/14/2001'
'12/01/2001'];

FutureVal = fvvar(CashFlow, 0.09, CFDates)
```

returns

```FutureVal =

170.66
```
