Commercial Energy Savings Calculator

Starting values are hypothetical. Replace them with your own figures. Inputs stay in this browser and are not included in the energy inquiry.

  • Hypothetical starting inputs. Replace every rate and usage figure with account-specific information.
  • Signed savings compare supply costs plus entered fees; unchanged delivery and taxes are excluded.

What belongs in this comparison?

Start with twelve consecutive months of billed consumption. Record electricity in kWh and natural gas in therms, even when the bills came from different months or suppliers. Use the same consumption for the current and proposed arrangements so the result measures the effect of rates and stated fees. If you only buy one commodity, leave the other commodity’s usage at zero. The tool requires some energy usage before it will calculate.

Identify exactly what each unit rate includes. A supplier energy rate and an all-in utility bill rate describe different scopes. Comparing them would make a cheaper-looking quote misleading. Utility delivery, demand, riders and taxes may continue under either arrangement; exclude unchanged items consistently or explicitly place comparable annual amounts in the fee fields.

How annual savings are calculated

Current modeled cost equals annual kWh multiplied by the current electricity rate, plus annual therms multiplied by the current gas rate, plus current annual fees. Proposed modeled cost uses the same quantities with the proposed rates and fees. Signed annual savings equal current cost minus proposed cost. The percentage uses current modeled cost as its denominator; when that denominator is zero, a percentage is not defined.

For an illustrative electricity-only account using 120,000 kWh, a change from $0.10 to $0.09 per kWh creates a $1,200 supply-cost difference before fee changes. A new $300 annual fee reduces that difference to $900. These figures demonstrate arithmetic. They do not show prevailing prices or indicate that an account can switch suppliers.

Rate savings and usage savings are separate

This calculator holds consumption constant. Replacing refrigeration equipment, changing operating hours or opening an additional location changes the amount of energy purchased and requires a second scenario. Entering reduced consumption only on the proposed side would mix procurement and operating improvements, making it harder to explain where the difference came from.

A fixed supply rate also does not make every bill component fixed. A lower energy rate can coincide with higher total spending if usage, demand or delivery costs rise. After running the comparison, inspect a complete projected bill and consider whether the contract changes pass-through charges, volume tolerances, payment terms or termination costs.

Use the result to organize a quote review

Save the usage period, bill units, rate definitions and fee assumptions alongside the result. Compare contracts with the same delivery start and term, and request clarification when one quote includes a component that another excludes. Check eligibility for the actual utility account before treating supplier choice as available. A location’s mailing address alone does not establish that choice.

A positive result identifies a modeled difference worth investigating. It is not a reason to cancel an existing contract without reviewing its notice and exit provisions. Use the contract break-even tool when there are one-time switching costs; use the electricity or gas offer comparison when you want a more focused view of one commodity.
