TIME & CHOICES

How to Compare Two Life Plans Without Counting an Hour Twice

A time budget becomes harder to interpret when one hour appears in several categories. Shared activities are valuable, but the capacity of a week remains 168 hours.

A few consistent accounting choices can keep a comparison understandable.

Choose a Rule for Shared Activities

Consider a one-hour walk with a friend. It contributes to movement and friendship. Entering one full hour under each category would make the allocation consume two hours.

You can handle this in several reasonable ways: give the hour one primary category, split the hour between categories, or create a combined category. Pick a convention and use it consistently in both versions of your plan.

The total describes time occupied. A note can preserve the additional meaning of the activity without adding more time to the ledger.

Check Bundled Entries

Work and commuting are another common overlap. Imagine forty paid work hours and five commute hours. The combined total is forty-five hours.

MethodEntered hours
Work and commute in one combined entry45
Work and commute as separate entries40 + 5 = 45
Combined entry plus a second commute entry45 + 5 = 50

The last method overstates occupied time by five hours. The same issue can occur when a trip, shopping or an outing already includes travel and travel is added again elsewhere.

Before comparing two plans, write down what each category includes. A label such as “work, including commute” carries a different meaning from “paid work.”

Keep the Comparison Conditions Stable

For the first comparison, change the choice you are investigating and hold other assumptions constant. If work hours change, keep sleep and other responsibilities steady unless there is a reason they would change too.

When looking over a longer horizon, also check that the two plans use the same horizon and the same relevant activity end dates. Different assumptions can be intentional, but they need to remain visible so the result is interpreted correctly.

Keep annual illustrations separate from a calendar-aware projection. Multiplying by 48 working weeks is a chosen simplification; a model with activity end dates and a different horizon may produce a different lifetime result.

Preserve an Overbooked Result

If the entered activities exceed capacity, leave that result visible while you inspect the entries. First check overlap. Then look at commitments that genuinely compete for the same time.

An overbooked plan can be useful information. Making the numbers fit by silently shrinking activities would hide the decision you still need to make.

Use the weekly worksheet to place the two plans side by side and note each category's boundary. Update the assumptions when your understanding changes.

Keep Your Entered Scenarios Together

Final Curtain offers free activity allocation and profile editing on iPhone. Its work and commute controls account for the bundled or separate entries, and its estimates use your selected life horizon and activity assumptions.

Optional one-time Pro adds side-by-side comparison of independently saved profiles, custom activity creation and the countdown widget. Comparison reads your saved plans; it does not automatically rewrite them. Profiles stay on the device.
