In our post of April 2, 2022, we discussed possible assumptions used by life insurance company actuaries in pricing single premium immediate life annuities (SPIAs). In that post, we provided implied discount rates consistent with quotes obtained from ImmediateAnnuities.com based on two different mortality assumptions (one based on life expectancy and the other based on a 25% probability of survival, which is the basis we recommend in our website for planning purposes). In our post of May 18, 2022, we updated these implied interest rates consistent with SPIA quotes available on that date.
In this post, we will examine the implied interest rate assumptions built into quotes from ImmediateAnnuities.com as of July 25, 2022 and compare the quotes and the implied interest rates with the results of the similar exercise we performed as of May 18. You may wish to revisit our prior posts for more general discussion of annuity pricing assumptions.
