Question

MATLAB: Write a function with the header: function [table] = myWhenCanIRetire(goal, PV, A, int) which generates a table of savings vs year [year, savings] it will take you to reach your retirement savings goal (goal) given a present sum of money (PV), an annual interest rate (int) and an annual contribution (A) added at the end of each year.

Test Cases: >> nYears = myWhenCanIRetire(200000, 1000,7000,.08) nYears = 1.00 8080.00 2.00 15726.40 3.00 23984.51 4.00 32903.27 5.00 42535.53 6.00 52938.38 7.00 64173.45 8.00 76307.32 9.00 89411.91 10.00 103564.86 11.00 118850.05 12.00 135358.06 13.00 153186.70 14.00 172441.64 15.00 193236.97 16.00 215695.92

Explanation / Answer

% matlab code

function [table] = myWhenCanIRetire(goal, PV, A, int)
year = 1;
while true
saving = PV*(1+int) + A;
table(year,1) = year;
table(year,2) = saving;
year = year + 1;
if saving >= goal
break;
end
PV = saving;
end
end

nYears = myWhenCanIRetire(200000, 1000,7000,.08);
for i=1:length(nYears)
fprintf("%0.2f %0.2f ",nYears(i,1),nYears(i,2))
end

%{
output:

nYears =
   1.00 8080.00
   2.00 15726.40
   3.00 23984.51
   4.00 32903.27
