    double res = invest * Math.pow((1 + interestrt), (year * 12));


    Firstly, if you're entering the interest rate as a percent, e.g. 3.25, then it should be

    interestrt/100

    and it's not 'year * 12' but just 'year'


                double futureValue = invest * Math.pow(1 + (interestrt/100), year);
            txtRes.setText(String.format("%,.2f", futureValue));

    Ok thank you for the help. That is exactly the fix I needed. So by doing inerestrt/100 is made interest rate a %,
    and the "%,.2f" gave it the correct decimal place right?
