Above is an example of future value of an amount at an incresing rate:Code:YR RATE INTEREST BALANCE 0 1000.00 1 .03 30.00 1030.00 2 .033 33.99 1063.99 3 .0363 38.62 1102.61 4 .03993 44.03 1146.64

$1000.00 at rate 3% 1st year, then the rate increasing by .10 each year.

As example, year2 rate = .03 * 1.10 = .033

What is the formula to calculate the future value in such circumstances?
