Restaurant electricity cost calculator
Estimate the monthly electricity cost of a U.S. restaurant while keeping energy use and peak demand separate. Replace every sample value with the figures from your bill and tariff.
Commercial electricity bill
of this estimate comes from the highest measured interval, not total energy use.
What would a 24,000 kWh restaurant bill look like?
Using 24,000 kWh at $0.12/kWh, an 82 kW billed peak at $18/kW, a $95 fixed charge, and 4.5% for taxes and riders produces an illustrative monthly estimate of approximately $4,651. Of that amount, about $1,476 comes from demand. This is a scenario, not a national restaurant average or utility quote.
The restaurant loads that usually matter
Restaurant electricity use is shaped by refrigeration, lighting, cooling, kitchen ventilation, electric cooking, dishwashing, hot water, and plug loads. ENERGY STAR reports that restaurants use roughly five to seven times more energy per square foot than other commercial buildings, while high-volume quick-service locations can use even more. The same source identifies refrigeration, lighting, and cooling as major electricity uses.
That does not mean every restaurant has the same energy intensity. A gas-heavy kitchen, an all-electric café, and a drive-through restaurant can have very different bills. Use the calculator as a transparent bill model, then compare its result with several real billing periods.
Inputs to collect before calculating
| Bill item | Where to find it | Why it matters |
|---|---|---|
| Monthly kWh | Usage summary | Prices total electrical energy consumed. |
| Billed peak kW | Demand or meter section | Can set a separate monthly demand charge. |
| Energy and demand rates | Tariff or charge detail | State averages cannot replace the actual tariff. |
| Fixed fees and riders | Charge detail | Explains the gap between simple usage cost and the bill. |
How to investigate a high restaurant bill
- Compare kWh, billed kW, and operating days with the same month last year.
- Check refrigeration temperatures, door seals, condenser cleanliness, and overnight cycling.
- Review startup schedules so ovens, HVAC, dishwashing, and electric water heating do not all ramp together.
- Confirm hood and makeup-air schedules match kitchen production rather than building occupancy alone.
- Price equipment choices using measured run time, not only nameplate power.
ENERGY STAR provides restaurant-specific benchmarking and efficiency guidance. It also covers certified commercial refrigerators, freezers, fryers, steam cookers, ice machines, ovens, griddles, hot-food holding cabinets, and dishwashers.
Frequently asked questions
How much electricity does a restaurant use per month?
There is no reliable single average for every restaurant. Floor area, service volume, menu, fuel mix, refrigeration, climate, and operating hours can change consumption substantially. The closest estimate comes from 12 months of the restaurant’s own bills.
Why can a restaurant have a high demand charge?
Cooking, refrigeration, ventilation, HVAC, dishwashing, and water-heating loads may overlap during preparation and service. If the utility bills the highest short interval, one period of simultaneous operation can set the monthly demand charge.
Does this calculator include natural gas?
No. It estimates the electricity portion of the utility bill. Gas-fired cooking and water-heating costs should be evaluated separately.
