With an annuity calculator I can calculate how much money do I need to collect so I can retire and live off it.
I can estimate my monthly living expenses and my remaining lifespan. But I have no good idea how much inflation adjusted return should I expect on it. I would need to hoard half the amount of money if I can have 3% real return instead of 0%.
If we assume a typical 50/50 post-retirement portfolio composed of stock and bond index funds, what percentage of real returns to should I calculate with when planning retirement?
