these code is how to find (the new mortgage values of a house), but I'm having troubles changing it to find (how long it will take to pay off a house).

disp('I can tell you how much you''ll have to pay for your house.')
disp([' '])
pv=input('What was your original mortgage value? ');
rate=input('What is the yearly interest rate on your home? ');
pmt=input('What is your mounthly payments? ');
nper=input('How many monthly payments have you made so far? ');
 
 m = (rate/100)/12;   
 nper = 10*12;       
 current_balance = 1:nper; 
for loop = 1 : nper
    pv = pv*(1+m)-pmt; 
    current_balance(loop) = pv;
	fprintf('The current balance after %d periods (out of %d) is %.2f\n', ...
		loop, nper, current_balance(loop));
end

All of the variables and the equation are still used, but Im thinking that I just need to change the fprintf line, but this is suppose to be in a while loop. I'm not sure if that changes much of the code

Hello, I think I have found a solution for you, or at least something close:

disp('I can tell you how much you''ll have to pay for your house.')
disp([' '])
pv=input('What was your original mortgage value? ');
rate=input('What is the yearly interest rate on your home? ');
pmt=input('What is your mounthly payments? ');
nper=input('How many monthly payments have you made so far? ');
 
 m = (rate/100)/12;   
 nper = 10*12;       
 current_balance = 1:nper;
 loop = 0;
while pv > 0
    pv = pv*(1+m)-pmt; 
    loop = loop + 1;
    current_balance(loop) = pv;	
end
fprintf('It will take %d periods to pay off the loan\n',loop);
