## Formula

Cost = kWh × price per kWh + fixed or demand charges.

- The price is entered by you in the currency you select; no conversion is done.
- Taxes are not added unless included in your price.
- Energy can come from the energy consumption calculator.
- Cost = kWh × price per kWh + fixed or demand charges.
- Inputs used: Currency, Energy used, Energy price, Fixed / demand charges for the period (optional).

## Inputs

- Currency
- Energy used
- Energy price
- Fixed / demand charges for the period (optional)

## Worked example: 4,200 kWh at 0.15 per kWh

Annual cost of the office unit.
1. Cost = 4,200 × 0.15 = 630.
2. No fixed charges: total USD 630.

## Common questions

### Why is there no default electricity price?

Prices vary widely by country, supplier and time of day. Using a made-up figure would give a misleading cost.

### What about time-of-use tariffs?

Split energy by period, run each with its own price, and add the results.

### Are taxes included?

Only if your entered price includes them.

### How do I use the Equipment Energy Cost Calculator?

Enter the required values for Currency, Energy used, Energy price, Fixed / demand charges for the period (optional). The calculator applies the formula on this page and shows the main result with any supporting breakdown so you can check the arithmetic.

### What formula does the Equipment Energy Cost Calculator use?

Cost = kWh × price per kWh + fixed or demand charges. The visible formula section above lists the calculation path and the edge cases the page handles, so the result can be checked without relying on the form alone.

### Can the Equipment Energy Cost Calculator be used for exact decisions?

Use it as a calculation aid, not as a substitute for checking the underlying rule, contract, policy, or professional advice that applies to your situation. When a result depends on local rules, personal details, prices, or dates, enter those values yourself and confirm them before acting.

## Limitations and assumptions

- No currency conversion.
- Taxes only if included in your price.
- Results are estimates for planning and learning. Real designs, installations and bids must be checked by a qualified, licensed professional against the codes that apply where you work.
- The result depends on the values you enter for this equipment energy cost calculator; it does not supply missing rates, rules, prices, dates, or assumptions for you.
