Timevalue

Timevalue is a simple Python package for finding the time value of money

pip install timevalue

Future & Present Cli Commands

Find future value of money for $1000$ at $0.03%$ interest for $2$ periods:

future 1000 .03 2 #returns 1060.90

Find present value of money for $1000$ at $0.03%$ interest for $2$ periods:

present 1000 .03 2 #returns 942.60

Annuity Cli Command

Annuities are payments are that are paid to you as a steady stream of income. Heres an example annuity.

Q1. Find the future value of an annuity cash flow of $1000$ with and interest rate of $0.06$ for $3$ periods.

annuity --future_value --cash_flow 1000 --interest_rate 0.06 --time 3 # returns 2673.011949461636

Say we want calculate the annuity present value given the cash flow as the result from Q1, use the --present_value and --pv flag to get the cash flow value:

annuity --present_value --cash_flow 2673.011949461636 --interest_rate 0.06 --time 3 --pv

Heres an example of growing annuity due.

annuity --future_value --due --cash_flow 1000 --interest_rate 0.06 --time 3 --growth_rate .10

Output:

3709.576
