Life Math

Allison Yost, PhD

What this is

How many more summers with everyone under your roof? How many more holidays with your mom? How many more years with the dog? Most of us never do this math. The numbers are smaller than you expect, and knowing them changes how you spend them.

Enter a few birthdays. Life Math counts the moments you still have together, in units you can hold: summers, holidays, Saturday mornings, weeks.

You

Month and year is all this needs. No day, no account.

Birth month

Birth year

Your people

Who do you want to see time with? Add as many or as few as you like. This works with nobody added, too.

Your holiday

Which holiday does your family count? Pick one or add your own.

Assumptions

Planning horizon

90 is a hopeful default, not a prediction. Change it to whatever feels right.

Kids leave home at

Retirement age

Holiday to count

Your birth month and year are all it needs to start.
