<prompt> Human: I couldnt find an online calculator for this. The lump sum would be put in an IRA and invested in some ETFs. 1565.15 per month vs. 109,054.96 Thanks for all the input. Ill probably take the lump sum and invest in the ETFs.Assistant: Another factor. Your descendants get to keep any of the money left over from 109,054.96. Whereas the pension disappears when you die. Human: A potentially important point.  <response>: Also pensions have a habit of being underfunded or reduced.
