How we rank products

Every ranking on this site is calculated, not hand-picked. Here is the whole method.

1. Specs come from official ENERGY STAR records

We enter only figures published on the ENERGY STAR certified residential electric cooking products dataset, and we link the product-finder search and the public dataset under every product. If a figure isn't published we show "Not listed" instead of guessing. Official annual energy consumption is printed on each card; on this dataset those official annual figures cluster tightly, so we do not use them as a primary score. When we add official cooking-zone wattages together, we label the sum computed. Obvious official unit errors, such as dimensions of several hundred inches, are noted and are not scored as inch values.

2. Each spec is scaled from 0 to 1

Each criterion has a fixed reference range, from a "weakest reasonable" value to a "best in class" value (for example 2 to 6 official cooking zones, or 1,200 to 6,000 W official maximum zone wattage). A product's figure is placed on that range and clamped between 0 and 1, so scores stay meaningful as products are added. Yes/no features count as 1 or 0. The ranges are listed below.

3. Weights decide what matters most

Each category lists its criteria and weights on the page. The score is the weighted average, multiplied by 10:

score = 10 × Σ(weight × scaled value) ÷ Σ(weight)

4. How missing data is scored

If a spec isn't published, the product scores at the lowest value any product in that category actually published, so an unpublished figure never outranks a published one. The page marks each such cell with an asterisk. Yes/no features that aren't stated count as no. Nothing is ever scored at the category average.

5. Prices and ratings switch on automatically

When our retailer feeds supply a current price or customer rating for at least 60% of products in a category, two more criteria join the formula: Price / value (20%) and Customer rating (15%, discounted when there are few reviews). Until then we show "Check price" and never estimate a price.

6. What the score can't tell you

Specs don't capture how evenly a burner heats a pan, how an oven bakes, or whether every zone can run at its official maximum wattage at the same time. Official zone wattage is a certified nameplate figure, not a measured time-to-boil test. Official cooktop low-power-mode energy is not a kitchen idle-power measurement you take at the wall. Oven cavity capacity is not in the ENERGY STAR fields we used. When we derive a figure from official numbers, such as adding official zone wattages, we label it computed. Use the score to shortlist, then read the pros, cons, safety notes and sources, and confirm voltage and amperage against your circuit. When we add hands-on testing notes, we label them clearly.

7. Money never changes the order

We earn affiliate commissions from some retailers. Commission rates are not an input to the formula, and no brand can pay for placement. See our affiliate disclosure.
