Standard 8 × 8 × 16 inch concrete masonry units (CMUs) cost $1.50 to $3.50 each in 2026 at most US home centers and masonry suppliers. The exact price depends on the block style (hollow vs solid, smooth vs split-face), the supplier, and your region.
Block prices have risen 20–30% since 2020 due to cement and aggregate cost increases. Expect $1.80–$2.50 for a standard hollow gray CMU at Home Depot or Lowe's. Solid blocks run 40–60% more.
Bulk pricing matters: orders of 100+ blocks typically get a 10–20% discount, and pallet quantities (90 blocks per pallet, typical) can knock another 5–10% off.
