I made this. My son is about to turn one.

My dad is 72 and my mom is 63.

I ran the life tables against how often we visit which was about once a month. At that rate my son would only see my dad 148 more times and my mom 248 more times before they passed away.

That was a bit shocking to me so we started seeing them more, now about every two weeks. My dad comes for breakfast, and my mom comes for lunch.

After running the numbers again my son will see my dad 321 more times and my mom 561 more times before they pass away. Small change, big difference.

Obviously all these are estimates. I averaged the years using the SSA 2022 period life tables and have the detailed method I used linked on the page.

The calculator behind the page is a small thing I built called Tend. You can run your own numbers, I would be curious if it changes anything for you as it did for me.
