Need to record multiple arrays within a while loop

Ive been stuck on this for a bit now and need help. I want to array all values of owed loan amount on a yearly basis within 20 years. I want to array the amount I would owe each year considering the loan payment increases with each years predicted salary growth(3%). Please help me be able to turn the amount owed, and salary after each loop into a saved array

clear, clc
year=0;
salary=60000;
poverty=19720;
protected=poverty*2.25;

while year<20
    owed=(salary-protected)*.083;
    salary=(salary*1.03);
    totalowe=sum(owed);
    totalowem=totalowe/12;
    year=year+1;
   
end
disp(owed)

Use indexing:

indexing is what you need

clear, clc
year=0;
salary=60000;
poverty=19720;
protected=poverty*2.25;
while year<20
    k = year+1;
    owed(k)=(salary(k)-protected)*.083;
    salary(k+1)=(salary(k)*1.03);
    totalowe=sum(owed);
    totalowem=totalowe/12;
    year=year+1;
   
end
plot(owed)
