Use conservative inputs first, then update the worksheet when real measurements or quotes arrive.
Keep a copy of the assumptions beside any vendor, budget, or internal review notes.

Set a realistic range from your own inputs instead of relying on a single generic estimate.
Prepare better questions for vendors, service providers, or internal budget reviews.
Keep assumptions visible so updates are easy when real quotes or measurements arrive.

Built for drivers comparing ownership scenarios. Use the worksheet as an early planning screen, not as a final quote or professional recommendation.
