How to repeat this loop?

I have been trying to find a way to get this loop to repeat itself after executing, but it just isn't working. Ideally, when the code finishes running the first time, it should ask for an initial balance again.

 LoopRepetition=0;
while LoopRepetition==0
InitialBalance = input('Enter the initial balance in US$ : '); % 10,000,3000,9000
% if initial balance is more than or equal to 5000, then interest rate is
% 2%. Anything else is 1%
if InitialBalance>=5000 
    rate=0.02;
    fprintf('\nYour minimum monthly payment is $%g\n',rate*InitialBalance+1)
    Minimum=rate*InitialBalance+1;
else
    rate=0.01;
    fprintf('\nYour minimum monthly payment is $%g\n',rate*InitialBalance+1)
    Minimum=rate*InitialBalance+1;
end
 MonthPay = input('Enter the Monthly Payment in US$ : '); % 12000, 4000, 2000
 month=0; % initialize months
Payment=0; % initialize payment
Interest=0;
fprintf('\nMonths \t Interest($) \t Payment($) Balance($)\n')
fprintf('  %2i          %2i           %2i        %2i\n',month,Interest,Payment,InitialBalance)
Balance=InitialBalance; 
 while MonthPay>=Minimum % initiates while loop if and only if monthly payment >= minimum payment
    while Balance~=0
        month=month+1; 
        Payment=MonthPay;
        Interest=rate*Balance;
        Payment=Interest+Balance;
        if Balance-Payment<0
            Balance=0;
        else
            Balance=Balance-Payment;
        end
        fprintf('  %2i          %2i           %2i     %2i\n',month,Interest,Payment,Balance)
    end
end
end

The code you've posted runs in a loop already, as long as it is nocht stopped by Ctrl-C. The loopcondition LoopRepetition==0 is always true, so pleae explain, what you want to change.

It is easier to reconsider your problem, if you post the relevant part of the code only.
