The formulas: cache savings = spend × repeat-share × 0.9 (a cache hit avoids the full provider cost; 0.9 accounts for imperfect hit rates). Routing savings = spend × routable-share × 0.7 × (1 − repeat-share). Routed tasks save roughly the price difference to a smaller model, applied to traffic the cache did not already absorb. Kertus reports measured savings net of provider-native discounts.
