How Our Estimates Are Built

How Electric Panel Cost builds its cost estimates: which sources we use, how the math works, what is our own estimate, and how pages are reviewed.

Where the numbers come from

Every price range on this site is taken from a named, published source, and each guide cites its sources on the page. When two sources disagree, we show the wider range or name both.

How the estimator calculates

The estimator prices the job line by line. Each line is a published installed-cost range, multiplied by your quantity where the cost scales with it, then by the region multiplier you choose. The low ends add up to the low total and the high ends to the high total, rounded to the nearest $10. The math runs in your browser; your inputs are not sent to us.

What is our own estimate

The region multiplier is our own estimate and is labeled "est." in the estimator. Everything else traces to a cited source. Results are planning ranges, not quotes: local labor rates, the condition of your service and code requirements move real bids.

See it worked through

The worked example shows one run of the estimator with every line and the total, so you can check the arithmetic.

Review and corrections

Each guide shows the date it was last reviewed. When a source updates its figures or a rule changes, we update the page and its date. If you spot an error, write to us at the address below and we will check it against the source.

Independence

Electric Panel Cost is published by Cornelia Cove LLC. We do not perform electrical work. Any referral arrangement with electricians never changes the estimator results.
