Simple interest formula is given by: Simple Interest = (P x T x R)/100 Where, P is the principal amount T is the time and R is the rate
Examples:
Input : P = 10000
R = 5
T = 5
Output :2500.0
We need to find simple interest on
Rs. 10,000 at the rate of 5% for 5
units of time.
Python Program for simple interest
# Python3 program to find simple interest
# for given principal amount, time and
# rate of interest.
def simple_interest(p,t,r):
print('The principal is', p)
print('The time period is', t)
print('The rate of interest is',r)
si = (p * t * r)/100
print('The Simple Interest is', si)
return si
# Driver code
simple_interest(8, 6, 8)
Output
The principal is 8 The time period is 6 The rate of interest is 8 The Simple Interest is 3.84
Time complexity: O(1)
Auxiliary Space: O(1)
Program for simple interest with Taking input from user
We can calculate the simple interest by taking P,T and R from the user.
# Python3 program to find simple interest
# principal amount, time and
# rate of interest taken from user.
def simple_interest(p,t,r):
print('The principal is', p)
print('The time period is', t)
print('The rate of interest is',r)
si = (p * t * r)/100
print('The Simple Interest is', si)
# Driver code
P = int(input("Enter the principal amount :"))
T = int(input("Enter the time period :"))
R = int(input("Enter the rate of interest :"))
simple_interest(P,T,R)
Output:
Input:
Enter the principal amount :3000
Enter the time period :7
Enter the rate of interest :1
Output:
The simple interest is 210.0
Time complexity: O(1)
Auxiliary Space: O(1)
