The resulting appliance cost returned as an object.

• The result is conditional on the entered prices and consumption model. Taxes, tiers, discounts, minimum charges, demand fees, depreciation, financing, maintenance, downtime, inflation, exchange rates, and uncertain future usage may not be included.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Compare several realistic usage scenarios and confirm each tariff or quote with its billing unit and effective date. Use discounted cash-flow analysis when costs occur across materially different dates.
