Age 5Explain it to a 5-year-oldStart with a picture
Imagine using Car Wash Water Cost per Car to answer this question: calculate metered water and sewer cost per completed vehicle wash? Enter Completed vehicle washes, Purchased water volume thousand gallons, Water and sewer price per thousand gallons, and 2 other inputs; the calculator shows Water-system cost per completed car. Try changing one number and watch what happens to Water-system cost per completed car. The answer tells you Water-system cost per completed car.
Age 15Explain it to a 15-year-oldConnect it to the formula
Use metered volumes where possible and include discharge, drought and reclaim-system operating rules. The rule is Water cost per car = purchased water and sewer charges − reclaim credit ÷ washes. Its input values are Completed vehicle washes, Purchased water volume thousand gallons, Water and sewer price per thousand gallons, Reclaim-system monthly operating cost, Avoided purchased-water and sewer value, and the main result is Water-system cost per completed car. Try changing one number and watch what happens to Water-system cost per completed car.
CollegeExplain it at college levelState the model precisely
This tool models one operating decision from explicitly supplied company assumptions. The implemented relation is Water cost per car = purchased water and sewer charges − reclaim credit ÷ washes, evaluated from Completed vehicle washes, Purchased water volume thousand gallons, Water and sewer price per thousand gallons, Reclaim-system monthly operating cost, Avoided purchased-water and sewer value to produce Water-system cost per completed car. Use metered volumes where possible and include discharge, drought and reclaim-system operating rules. The model omits unentered taxes, cash timing, legal constraints and market uncertainty. Compare the output with company records and a downside scenario before committing resources.
The decision this tool supports
Calculate metered water and sewer cost per completed vehicle wash.
Why the business model works
Use metered volumes where possible and include discharge, drought and reclaim-system operating rules.
Inputs and operating assumptions
This model uses Completed vehicle washes, Purchased water volume thousand gallons, Water and sewer price per thousand gallons, Reclaim-system monthly operating cost, Avoided purchased-water and sewer value. Keep currencies, accounting treatment and time periods consistent with one another.
The formula
Water cost per car = purchased water and sewer charges − reclaim credit ÷ washes
What the calculator produces
The primary output is Water-system cost per completed car; it also exposes Net monthly water-system cost, Purchased water gallons per completed wash. Change one assumption at a time so the comparison remains explainable.
Before using the result in a decision
This compact model cannot capture every tax, accounting, legal, market or operational condition. Compare the output with current company records, cash timing and the downside scenario before committing resources.
