What is the amount of 20 equal annual deposits that can provide 40 annual withdrawals when a first withdrawal of $2,000 is made at the end of year 21 and subsequent withdrawals increase at the rate of 3 % per year over the previous year’s withdrawal. Determine the deposit amounts based on the interest rate of 7 % compounded annually.
Withdrawal per annum = $2,000
Rate of increase in withdrawal = 3%
Interest rate = 7%
Present Value of the withdrawals as at Year 21:

Future value of Deposits = Present Value of withdrawals
Annual Deposit * FVAD(7%, 20) = $39,107.99
Annual Deposit * 43.86517678 = $39,107.99
Annual Deposit = $39,107.99 / 43.86517678
Annual Deposit = $891.5498
