The Worth It or Not standard

The answer is only as useful as the reasoning behind it.

  1. 01

    Start with your numbers.

    Broad defaults are a starting point. Important assumptions stay visible and editable.

  2. 02

    Count what leaves and what remains.

    Costs, retained value, timing, and tradeoffs belong in the same comparison.
