How can I modify the iteration loop?

I am trying to modify the iteration loop, so that I can show the final payment of the car loan and the month which the final payment occurs.

clc; clear; % clear the command window and memory
x = 2000; % starting balance of the current account
r = 0.015/12; % the interest rate on the current account
sal = 24000; % salary
liv = 1800; % monthly living expenses
carloan = 15700; % starting sum of the car loan
carrep = 357; % monthly car loan repayments
carrs = 0.05/12; % monthly car loan interest

N = 120; % the number of months to consider
t = 1:N+1; % our timeline
xhist=zeros(1,N+1); % create a vector to hold the account history
xhist(1) = x;
carhist=zeros(1,N+1); % vector to hold the car loan history
carhist(1) = carloan;

for m=1:N % commands inside the loop are executed for each month
    x = (1+r)*x+sal/12-liv; % apply the interest and pay in the salary
    carloan = (1+carrs)*carloan; % apply the interest to the car loan
     if carloan-carrep>0
        x = x-carrep; % take money off the current account...
        carloan = carloan-carrep; % ...and make car loan payment
    else
        x = x-carloan; % take the remainder off the current account...
        carloan = 0; % ...and close the car loan
    end
    xhist(m+1) = x; % save the sum at the beginning of month m
    carhist(m+1) = carloan; % do the same for the car loan
end

fprintf('%.2f\n',x); % balance at the beginning of (N+1)th month
fprintf('%.2f\n',carloan); % print the outstanding loan balance

So far I've only managed to get the car loan balance for a given month.

Before you do

        x = x-carloan; % take the remainder off the current account...

print out x -- it will be the final payment. m will be the month number.

After you do the next command

          carloan = 0; % ...and close the car loan

add a "break"
