Why trust the numbers
Same data as the pricing desk
Calculators share the snapshot behind the pricing directory — list prices pulled from official vendor pages, with cache, batch, and per-tier rates carried through. When a vendor reprices, every preset, example, and comparison here recomputes. Method details: methodology. Wrong number? Report it.
