Had posted a question earlier about errors. Thanks to a few people here I was able to fix that issue. Now I've run into the issues of my Compound Interest Calculator giving the wrong calculation when you input the principal, compounded interest (yearly, monthly, etc..), interest rate (0.03, etc...), and the amount of years.
Other Q link: final = P * (((1 + (r/n)) ** (n*t))) TypeError: unsupported operand type(s) for /: 'str' and 'int'
So from the previous code I removed p = 10000, n = 12, r = 0.08 because it would give a large number when you input different numbers. My hope was it would calculate it with the numbers inputted, but it doesn't.

# User must input principal, Compound rate, annual rate, and years.
P = int(input("Enter starting principle please. "))
n = int(input("Enter Compound intrest rate.(daily, monthly, quarterly, half-year, yearly) "))
r = float(input("Enter annual interest amount. (decimal) "))
t = int(input("Enter the amount of years. "))

final = P * (((1 + (r/n)) ** (n*t)))
#displays the final amount after number of years.
print ("The final amount after", t, "years is", final)
# At the moment it is displaying a very random number.

Enter starting principle please. 1000
Enter Compound intrest rate.(daily, monthly, quarterly, half-year, yearly) 1
Enter annual interest amount. (decimal) 0.01
Enter the amount of years. 1
The final amount after 1 years is 1010.0

The final amount should be 1000.10. Not sure what is going on. Trying to see if there is a way to make P, n, r equal the number a user inputs that will result in the correct final answer.

Thanks in advance.

If you are entering interest in percentages, you should take care of that in your code.

final = P * (((1 + (r/(100.0 * n))) ** (n*t)))

Please try the below Python code for Compound Interest:

p = float(input('Please enter principal amount:'))
t = float(input('Please enter number of years:'))
r = float(input('Please enter rate of interest:'))
n = float(input('Please enter number of times the interest is compounded in a year:'))
a = p*(1+(r/(100*n))**(n*t))
print('Amount compounded to: ', a)

Based on this:
Compound Interest Formula
FV = P (1 + r / n)^Yn,
where P is the starting principal, r is the annual interest rate, Y is the number of years invested, and n is the number of compounding periods per year. FV is the future value, meaning the amount the principal grows to after Y years.

P = int(input("Enter starting principle please. "))
n = int(input("Enter number of compounding periods per year. "))
r = float(input("Enter annual interest rate. e.g. 15 for 15% "))
y = int(input("Enter the amount of years. "))

FV = P * (((1 + ((r/100.0)/n)) ** (n*y)))

print ("The final amount after", y, "years is", FV)

P = int(input("Enter starting principle please: "))
n = int(input("Enter number of compounding periods per year: "))
r = float(input("Enter annual interest rate: "))
y = int(input("Enter the amount of years: "))

FV = P * (((1 + ((r/100.0)/n)) ** (n*y)))

print ("The final amount after", y, "years is", FV)
