If I have a 10,000 death benefit at work that is left on deposit for 7 years at an annual interest rate of 5%. The balance after 7 years is what? and then is going to be paid out in 120 equal payments. During the payout period, interest is credited at an annual interest rate of 3%. Would the payouts continue to be the same?

10,000 x 5% = 500.00 so do I then take the balance of 10500 x 5% or is it going to be a steady 500 for all 7 years which out be a total of $3500. earned?
