How many more visits with your parents are left?
If you moved away, you see your parents a handful of times a year, and each visit lasts a few days. Multiply that by the years they realistically have left and the number is smaller than it feels. This template turns uncertain lifespans into a distribution instead of one scary point estimate, so you can see the median, the downside, and what changing your cadence actually buys.

After you install, this is the model to open.
How Many Visits With Your Parents Are Left?
- In your spreadsheet, click the Sortia icon in the strip of icons down the right-hand edge. No strip? Click the arrow at the bottom-right to open it. You can also use Extensions, then Sortia, then Open Sortia.
- Click Start from a template and put that name in the search box.
- Pick the card with that name and click Load this template. It arrives on a new tab with real numbers already in it.
This one runs on a Pro engine, and every free install includes five full-quality runs on your own numbers, shared across all five Pro engines rather than five for each. After that, Pro is $199/year.
The answer
Across 10,000 simulated futures at the default cadence:
- Visits remaining (median)
- ≈65 at 3 trips a year
- Lifetime together already behind you
- 97% median across simulations
- Chance you have under 45 visits left
- 9% about 1 in 11 futures
- One extra trip a year buys
- +65 days ≈22 more visits, on average
At three trips a year the median future holds about 65 visits, and roughly 97% of all the days you will ever spend with your parents are already behind you. Even the luckiest futures only push that share down to about 96%. The lever that actually moves the number is cadence: one extra trip a year buys back about 65 more days together.
The model
You enter three ages and a visit cadence; each parent's lifespan is simulated around actuarial life expectancy.
| Your age | 35 |
| Parents' ages | 65 and 67 |
| Visit cadence | 3 trips a year, 3 days each |
| Parent 1 lifespan | 85 ± 6 years (uncertain) |
| Parent 2 lifespan | 83 ± 6 years (uncertain) |
| What-if lever | +1 extra trip per year |
Once it is in your sheet
- The model arrives with real numbers in it and runs as it stands, so you can press the button first and understand it second.
- Change the numbers to yours. The sheet marks which cells are inputs and which hold formulas, and most labels carry a note explaining the row.
- Press the run button at the bottom of the panel. It is labeled for the tool you are in, and the result lands on its own tab, with a written reading of it beside the figures.
