ROI of Everything
Less guessing. More context.

Run your
own numbers.

Cheaper gas: worth the detour? ↗
Compare fuel savings with the added drive. Count only the extra distance and time beyond your normal route.
The annual shower audit ↗
Estimate water, heating, and time. This is a cost comparison, not a health recommendation. Water rate includes sewer; heating efficiency is a fraction (0.90 = 90%).
Buy back your time ↗
What does outsourcing a recurring chore cost per hour freed? Include supplies or other costs you avoid. Time freed is not automatically income earned.
