Python Program to Calculate Compound Interest using Function

# Program to calculate compound interest using function

# user-defined function
def compound_interest(principal, rate, time, number):
    amount = principal * pow( 1+(rate/number), number*time)
    return amount

# inputs from user
principal = float(input('principal amount: '))
rate = float(input('interest rate: '))
time = float(input('time (in years): '))
number = float(input('Number of times that interest is compounded per year: '))

# conversion rate
rate = rate/100

# function call
amount = compound_interest(principal, rate, time, number)

# calculating compound interest
ci = amount - principal

# printing result
print('Compound interest = %.2f' %ci)
print('Total amount = %.2f' %amount)

Output:

principal amount: 2000
interest rate: 2
time (in years): 5
Number of times that interest is compounded per year: 2
Compound interest = 209.24
Total amount = 2209.24
