Commercial electricity calculators
Every calculator on this site runs the same versioned engine we use internally, shows its formula and assumptions, and distinguishes a benchmark from an executable offer. None of them is a form pretending to be a calculator.
A commercial electricity calculator is only useful if it separates supply from delivery and models demand charges. Multiplying kilowatt-hours by an average rate produces a number that is wrong for almost every commercial account, because it ignores the demand and delivery charges that a supplier cannot change.
The calculators
Canadian business bill calculator (CAD)
Enter Canadian energy blocks, billed demand, fixed charges and tax assumptions. Includes an optional dated NB Power component example.
Rate checker: is my rate high?
Compare what you pay per kWh with what businesses in your state pay on average, from EIA data.
Cost estimator: what should my building pay?
Pick a building type, its size and your state, and see what surveyed buildings like yours used and what that costs, from federal survey data.
Commercial bill calculator
Split a commercial bill into supply, delivery, demand, fixed and taxes, and see the all-in effective rate.
Load factor calculator
The single best diagnostic for whether an account is on the wrong rate schedule.
Demand charge and ratchet calculator
Model billed demand under a ratchet clause, where a past peak still sets the floor.
Renewal window checker
When your decision window opens, and what happens if you let it pass.
Compare supplier quotes
Put two to four quotes on one scale: fees and term spread across the kWh, the all-in price, and what each leaves out.
How these differ from most electricity calculators
- They separate supply from delivery. A calculator that returns one blended number cannot tell you which part of your bill is contestable, which is the only question that determines what to do next.
- They model demand charges and ratchets. On a low load factor commercial account these frequently outweigh the supply rate, and a ratchet clause can keep a single past peak in your bill for months.
- They show the formula. Every one publishes the arithmetic, so you can reproduce the result or find our mistake.
- They run server-side first. The numbers are in the page before any JavaScript executes, so the result is readable, printable and quotable without depending on the browser.
- They do not produce a rate you can buy. No calculator can. Commercial supply pricing depends on a verified account, and anything that presents a public figure as your price is selling something.
Every formula is published in the methodology, together with the known limitations — including the fact that the engine has not yet been validated against real bills.
