Marble slab calculator: cost, weight and container load

Three quick tools fed by the live index data. All outputs are estimates for planning — a real quote from the mill replaces them in 48 hours. Free to embed and cite (CC BY 4.0).

1. Countertop cost calculator

Material cost for polished 2 cm slab, warehouse vs factory-direct. Fabrication and installation are added as a US-typical range you can edit.

Factory-direct = 40–70% of warehouse slab price (the index's 30–60% saving band). Freight, duty and templating excluded. Market estimates, August 2026.

2. Slab weight calculator

Natural stone weighs roughly 2.7 g/cm³ (marble, granite, quartzite all sit between 2.6 and 2.8). Weight decides crating, forklift class and freight cost.

3. Container load calculator

How many slabs fit a sea container is a weight question, not a volume one: a 20ft box maxes out around 26 t payload, a 40ft around 27 t — slabs hit the weight limit long before they fill the space.

Assumes 2.7 t/m³ and ~8% allowance for A-frames and crating. Payload limits vary by carrier and road rules at destination — confirm with the forwarder.
