Usage (examples)

Annuity

present value of an annuity certain can be calculated by the code below

>> from phew import Annuity
>> annuity = Annuity(interest_rate = 0.1,number_of_terms = 4,amount = 500)
>> annuity.certain_present_value()
>> 1584.9327231746472

Interest rates

effective annual rate of interest can be calculated by the code below

>> from phew import Interest_rates
>> rate = Interest_rates.compute.effective_interest_rate(nominal_interest_rate = 0.12,number_of_compounding_periods = 12)
>> rate
>> 0.12682503013196977

COLA

Growth of a fund given inflation values can be estimated by the following code

>> from phew import Cola
>> cola = Cola(initial_fund = 1000,data = [0.12,0.2,0.21],method = 'inflation')
>> cola.fund_growth()
>> array([1120.  , 1344.  , 1626.24])

Premium

Gross rate can be calculated by the following code

>> from phew import Premium
>> gross_rate = Premium.gross_rate(pure_premium = 2000,expense_ratio = 0.23)
>> gross_rate
>> 2597.402597402597
