The formula for compound interest is Final amount = Base amount * (1+(rate of interest/times compounded per year))^(number of times compounded per year * how many years pass)To put this into PHP, it would go something like this:function calcInt($rate, $numYear, $yearsElapsed, $base){$finalAmount = $base*((1+($rate/$numYear))^($numYear*$yearsElapsed));return $finalAmount;}To call this function and print the output, put:echo $finalAmount(.05, 2, 4, 5000);That would output the final amount if the interest rate is 5%, it's compounded twice per year, 4 years elapse, and the initial amount was $5000.
Not enough information. You also need to know: * The final amount of money * Whether simple or compound interest is known
The final amount is $1,647.01
That completely depends on what rate of interest you can expect your investment to earn, and how often you can expect the investment interest to be compounded. The assumed rate of interest has more effect on the final value than even the annual payment has, yet the question ignores it completely.
Perhaps, depending on context, "final investment decision".
(final amount/original amount)*100 This is NOT the percentage change.
