This package includes financial math calculations for actuarial calculations such as annuity calculations, amortization schedule, sinking fund calculations and constructing tables with those formulas.

Installation

• pip install actuarialCalculations

Annuity Calculations

Calcuating present value: Assuming our user would like to know the downpayment amount with provided kwargs below;

Logic: terms, period and interest amount rate. Price - (presentValue* _N _ Repay Amount ) = Down payment

Calculating the future value: Assuming our user pays at the end of the given period, so our program should accumulate the value with gthe iven interest rate;

Logic: Accumulated Down payment(1+i)**N = Accumulated Price(1+i)*N - (AccumulatedValue_N _ Repay Amount)

Calculating The Down Payment with Given Time Value: Assuming our user wants to calculate the downpayment with the given period of time

Logic: Accumulated Down payment = Accumulated Price ** T -(presentValue * Repay Amount ) ** T- (AccumulatedValue * Repay Amount)**-(N+T) / (1+i)**T

USAGE

.. code:: python

'''
Present Value method takes 5 parameters as intergers and returns downpayment amount
'''
presentValue = PresentValue(
    InterestRate, effectiveInterestTerms, fixedPeriod, repayAmount, price)

'''
Accumulated Value method takes 5 parameters as intergers and returns downpayment amount (future value)
'''
accumulatedValue = AccumulatedValue(
    InterestRate, effectiveInterestTerms, fixedPeriod, repayAmount, price)

'''
Calculate Given Time method takes 5 parameters as intergers and returns downpayment amount at any given time.
'''
calculateGivenTime = CalculateGivenTime(
    InterestRate, effectiveInterestTerms, fixedPeriod, repayAmount, price)

Amortization Schedule Calculation

method takes 4 parameters

Interest rate Years Frequency of the interest that hits in that period of time Loan Amount

USAGE

.. code:: python

'''Create an instance of CalctulateAmortization class and pass the parameters as intergers '''
calculate = CalctulateAmortization(interestRate, years, frequency, loanAmount)
'''To run the calculations we need to call execute funtion '''
calculate.execute()

Sinking Fund Calculation

method takes 4 parameters

Interest rate Years Frequency of the interest that hits in that period of time Amount

USAGE

.. code:: python

''' Create an instance of CalculateSinkingFund class and pass the parameters as integers'''
calculate = CalculateSinkingFund(interestRate, years, frequency, amount)
'''To run the calculations we need to call execute funtion '''
calculate.execute()
