How much of tariff costs reached retail prices within six months?
Core argument: Product-level regressions estimate that ~4–20% of tariff-induced cost increases showed up in retail prices within 6 months, implying a 20% tariff raised affected goods' retail prices by about 3–4% relative to unaffected products in the same category.
Using product-level regressions that relate monthly price changes to changes in applied tariff rates, we find that ~4 to 20% of tariff-induced cost increases were reflected in retail prices within 6 months. This magnitude is consistent with incomplete but nontrivial transmission, implying that a 20% tariff raised the retail prices of affected goods by about 3 to 4% relative to unaffected products in the same category. Pass-through is higher for goods facing larger tariff hikes and in sectors with thinner distribution margins. Aggregating these product-level effects using official CPI expenditure weights, we estimate that the 2025 tariffs added roughly 0.7pp to the all-items Consumer Price Index within six months of implementation. This contribution is economically meaningful: without the tariffs, the annual inflation rate in the all-items Consumer Price Index (CPI-U, NSA)—which stood at 2.9% in August 2025—would have been close to 2.2%, a level broadly consistent with the Federal Reserve’s inflation target. After 6 months, about 20% of the tariff changes were reflected at the consumer level, [suggesting that] pass-through will continue to accumulate gradually over time, putting persistent upward pressure on inflation statistics.
