Is this accurate enough to decide?

It is accurate for the assumptions you enter. Use it for planning, then validate the most sensitive inputs with primary sources when stakes are high.

What if I don’t know an input?

Model a range (low/base/high). If the decision flips across the range, that input is your next research priority.

Run a base case, a downside case, and a managed response case. If the plan survives the downside, the decision is more robust.

Inputs are the only “truth” the model sees. Clean input definitions make outputs like kWh usage and monthly cost meaningful.

This guide helps you define wattage, hours/day, and electricity rate so the calculator reflects your real scenario—not a spreadsheet fantasy.

Before typing, decide whether values are monthly, annual, per-unit, or per-order. Most errors come from mixing these silently.

If you’re unsure, re-run with a simpler scenario and confirm the output direction.

Key inputs: wattage, hours/day, and electricity rate.

Be consistent about units (monthly vs annual) and scope (include fees/taxes if they exist in real life).

Compare outputs like kWh usage and monthly cost across scenarios instead of trusting one number.

If the decision changes under downside assumptions, build a buffer or revise the plan.
