usefulHQ works out what things actually cost. We track real prices, normalise them into a single number you can compare, and publish the ranking. Alongside that sits a set of free calculators and converters for the everyday things you look up once and then need again next week.
Most comparison sites list prices. A price on its own tells you very little, because the cheapest drive is not the best value per terabyte, the cheapest ink cartridge is rarely the cheapest per page, and the cheapest gold coin usually carries the worst premium over the metal it contains. So every comparison here is built around one normalised metric and sorted by it:
Cost per terabyte for storage. Cost per printed page for ink. Premium over spot for bullion. Sugar per 100g for cereal. Cost per watt for generators. Protein to sugar ratio for protein bars. Frames per dollar for graphics cards.
That is the whole idea. Pick the number that decides the purchase, work it out honestly for every product, and put them in order.
Live prices are pulled from public APIs rather than typed in by hand: eBay for used-market prices across roughly 600 tracked models, Scryfall and the Pokémon TCG API for trading card values, CheapShark for PC game deals, and a live metals feed for gold and silver. Scheduled jobs refresh them automatically and take a dated snapshot each day, which is how the price history and the "lowest in the last 30 days" figures are built.
Everything else is researched and recorded by hand: cartridge page yields, nutrition panels, software pricing tiers, warranty terms. Where a figure is an estimate or an indicative street price, the page says so rather than dressing it up as precision.
Some links to retailers are affiliate links, mainly Amazon and eBay. If you buy after clicking one, we may earn a commission at no extra cost to you. Some pages also carry ads.
What that does not buy is a position in a table. Nothing here is sponsored, no brand has paid to be included or ranked, and no ranking is adjusted for whether a product happens to be one we earn on. Tables are sorted by the metric, and if the best value product is one with no affiliate programme at all, it still sits at the top. Where a page earns commission, it says so on the page.
Prices move, retailers change specifications, and a figure that was right last month can quietly stop being right. When we find an error we fix it and, where it changed a conclusion, we say what changed. If you spot something wrong, we would genuinely like to know.
usefulHQ is a small independent operation run from Australia, not a media brand with a content team. Prices are shown in the currency each page states, and calculators run entirely in your browser: nothing you type into one is stored or sent anywhere.
