How to measure a kibble's value for money?

Value for money is measured by crossing two axes on a common basis: verifiable nutritional quality and delivered cost per day. A good ratio pairs quality suited to the life stage with a contained cost per day, never one without the other (WSAVA, 2021). In depth ### Two inseparable axes Value for money ties the food's nutritional adequacy to its cost per day; neither alone is enough. A cheap but unsuitable food has no value, and an excellent food beyond a sustainable budget has none either. The assessment grid must be technical before it is financial, because price says nothing about quality (NorthPoint Pets). On quality, WSAVA proposes clear criteria: suitability to the life stage, a qualified nutritionist, quality control, and the ability to supply the full nutritional analysis on request (WSAVA, 2021). The decisive point: intake should be expressed in grams per 1,000 kcal, an energy basis that makes two foods truly comparable, where a raw percentage distorts the comparison between different densities. ### Weight, then decide Once quality is judged adequate for both foods, the costs per day are compared, delivery included. At equal quality, the lowest cost per day wins; at equal cost, the better adequacy and transparency win. This weighting avoids three frequent errors: comparing on price per kilo alone, confusing high price with quality, ignoring delivery costs.
