# Future value

The `numpy`

module also contains a similar function, `.fv(rate, nper, pmt, pv)`

, which allows you to calculate the future value of an investment as before with a few simple parameters:

**rate:**The rate of return of the investment**nper:**The lifespan of the investment**pmt:**The (fixed) payment at the beginning or end of each period (which is 0 in our example)**pv:**The present value of the investment

It is important to note that in this function call, you must pass a **negative** value into the `pv`

parameter if it represents a **negative cash flow** (cash going out). In other words, if you were to compute the future value of an investment, requiring an up-front cash payment, you would need to pass a negative value to the `pv`

parameter in the `.fv()`

function.

Instructions

**100 XP**

- Using Numpy's
`.fv()`

function, calculate the future value of a $10,000 investment returning 5% per year for 15 years and assign it to`investment_1`

. - Calculate the future value of a $10,000 investment returning 8% per year for 15 years and assign it to
`investment_2`
