Calculating compound interest using a for loop
显示 更早的评论
-Someone saves a sum of 100 Euro on the bank against an interest rate of 5%. The interest is paid at the end of each year. Calculate the total sum after 16 years using a for-loop.
-Calculate the total sum when in the 7th year the interest rate is increased to 6%. To do this, insert an if-statement inside the for-next loop.

Sounds a bit like a homework question. At the very least it might be worth showing that you've had a crack at writing something to solve the problem, even if it doesn't work.

What about:
savings=100;
for i=1:16
savings=savings*1.05
end
After all, you don't need to keep a record of the savings after every year

You could store it in a matrix if you felt the need (though the question posed originally does not require the value to be stored, only the result after 16 years). You've already done something similar in the attempt you made, so think about how would you adapt it to meet your requirements?

x=1000;
y=0.1;
t=2;
d=x*(1+y)^t
