FYI, Open Social Security is a pretty good tool for evaluating different scenarios.

I can't figure out what lifespans that site assumes.
I'm a data nerd, so wanted to know as well. Per ChatGPT Enterprise:
The "optimized" scenarios on OpenSocialSecurity.com are based on
mortality assumptions that you choose (or leave at defaults), combined with actuarial probability tables. It is not using a single fixed life expectancy like "age 85."
By default, the calculator uses:
- Social Security Administration cohort life tables
- Probability-weighted survival modeling
- Present-value calculations of lifetime benefits
In other words, it computes the
expected lifetime value of each claiming strategy by weighting outcomes across many possible lifespans. It is essentially doing actuarial math, not assuming one deterministic death age.
So….basically uses your DOB and SS mortality tables. Seems like a decent input.
