If we assume an annual deposit of $10,000 @ 3% compounded annually for 30 years, then the total amount you will have saved would be $475,754.16. Now, here is the problem. If, in 30 years from now you began to withdraw $100,000 per year from that annuity @ 3% interest rate, I'm afraid to inform you that it will only last you for about 5.25 years. So, you can see, it's nowhere near enough to last you for 10-20 years that you might live after, let us say, 65 years. To withdraw $100,000 per year for 15 years at 10%, you would need to have saved about $760,000 in 30 years from now. To save that much at 3%, you would have to deposit about $16,000 per year. Or you would have to earn about 5.8% interest on your deposits for that 30 year period. I hope I answered your question.
