Hi, I am very new to python and i currently had to do an assignment and eventhough i could do most of it but got struck in the middle. I hope i could get some help you finish my assignment. Thanks

Basically i have to write a python program to generate the below:

 balance = 4213
              annualInterestRate = 0.2
              monthlyPaymentRate = 0.04
              
              Result Your Code Should Generate:
              -------------------
              Month: 1
              Minimum monthly payment: 168.52
              Remaining balance: 4111.89
              Month: 2
              Minimum monthly payment: 164.48
              Remaining balance: 4013.2
              Month: 3
              Minimum monthly payment: 160.53
              Remaining balance: 3916.89
              Month: 4
              Minimum monthly payment: 156.68 

Here is my code for that:

 b0 = 4213
print('balance =' + str(b0))
r = 0.2
print('Annual interest rate =' + str(r))
m = 0.04
print('montly payment rate =' + str(m))

Month = 1
while Month <= 4:  
    print('Month:' + str(Month))
    mmp = round(m * b0, 2)
    print('Minimum monthly payment:' + str(mmp))
    ub0 = b0 - mmp
    rb = round(ub0 + (r/12.0 * ub0), 2) 
    print('Remaining balance:' + str(rb))
    Month = Month + 1    
    print('Month:' + str(Month))  
    mmp = round(m * rb, 2)
    print('Minimum monthly payment:' + str(mmp))
    ub0 = rb - mmp
    rb = round(ub0 + (r/12 * ub0), 2)
    print('Remaining balance:' + str(rb))
    Month = Month + 1 

When i run the above i am getting the following:

balance =4213
Annual interest rate =0.2
montly payment rate =0.04
Month:1
Minimum monthly payment:168.52
Remaining balance:4111.89
Month:2
Minimum monthly payment:164.48
Remaining balance:4013.2
Month:3
Minimum monthly payment:168.52
Remaining balance:4111.89
Month:4
Minimum monthly payment:164.48
Remaining balance:4013.2
Total paid:199.8
Remaining balance:4013.2 

As you can see i got only two months correct but after that the last two months have the same values as the first two months. Could somebody point to me where i am going wrong.

Thanks

You always subtract the payment from the original balance (b0) on each pass through the loop

b0 = 4213 
print('balance =' + str(b0)) 
r = 0.2 
print('Annual interest rate =' + str(r)) 
m = 0.04 
print('montly payment rate =' + str(m)) 
min_payment=round(m * b0, 2) 
remaining_balance=b0
Month = 1 
while Month <= 4:   
    print('\nMonth:' + str(Month)) 
    print('Minimum monthly payment:', min_payment) 
    remaining_balance -= min_payment
    print('Remaining balance:', remaining_balance) 
    Month = Month + 1
