# Continuous money flow

### Continuous money flow

#### Lessons

In most companies, we want to look at the revenue they invest over time. They will mostly look at the present value, and future value of their investments. To calculate the present value and future value, we use the following formulas:

$PV = \int_{0}^{T}R(t)e^{-rt}dt$

$FV = e^{r^{T}}\int_{0}^{T}R(t)e^{-rt}dt$

Where:

$R(t)$ = revenue stream

$T$ = the total amount of time invested

$r$ = interest rate compounded continuously

Clarifying Revenue Stream

Present and Future value

Patsy deposits \$10000 into a savings account each year for a total of 10 years. If the account earns an interest rate of 10% compounded continuously:

i) Find the present value

ii) Find the future value

• 2.

Suppose the revenue stream is the function $f(t) = 100e^{.02t}$, where $t$ is in years, for a total of 6 years. If the money can earn 3% annual interest compounded continuously:

i) Find the present value

ii) Find the future value

• 3.
Suppose the revenue stream is the function $R(t) = 1 + t$, where $t$ is in years, for a total of 5 years. If the money can earn 4% annual interest compounded continuously, find the present value.
