I have tried this but i think both of them are wrong

/*1. (1) DO LOOP- CONSTANT ANNUAL INTEREST RATE OF 10% */


data earning;
do year= 1 to 15;
rate=0.1;
amount+5000;
amount+(amount*0.1);
output;
end;
run;


/*1. (2) DO LOOP- COMPOUNDING ANNUAL INTEREST RATE OF 10% */

data earning2;
do year= 1 to 15;
rate=0.1;
amount+5000;
earned+(amount+earned)*rate;
output;
end;
run;

And what are the values you would expect?

DO LOOPS (1) SIMPLE INTEREST- interest will calculate every year but that interest will add in amount after 15 years
(2) COMPOUND INTEREST-every year interest will add in amount

SAS also has a number of financial functions and/or options for the FINANCE function that allow many calculations of this specific type without any looping.
