Most often people in the US ask for a price per square foot of the material by itself, so they can compare with other flooring options apples to apples. Note that grooved and virgin sheets are the same cost, only thickness of the product affects price. All are based on standard 50cm x 200cm sheet (1 square meter). Here you go, based on Fall 2018 exchange rate:

4mm – 76 euros per sq meter, 7 euros per sq foot ($8.10)
6mm – 130 euros per sq meter, 12.10 euros per sq foot ($14.00)
8mm* – 164 euros per sq meter, 15.25 euros per sq foot ($17.66)
12mm – 219 euros per sq meter, 20.33 euros per sq foot ($23.54)
*Most popular thickness

If you’re looking for a rough estimate for the total cost of your project materials, you should be able to multiply your overall square footage by one of the following figures (includes 6mm cork, adhesive, caulk (if used) clear coat and shipping from France to USA).

Based on currency exchange rates fall 2018:

• Smaller projects (40 sq feet/ 4 sq meters or less), no caulked grooves: $18/sq foot, $194/sq meter
• Medium sized projects (up to 100 sq feet/ 10 sq meters), with caulked grooves, optional borders: $24.50/sq foot, $260/sq meter
• Larger projects (more to come…)

If using 8mm cork, add 20%
If using 12mm cork, add 60%

Each large SeaCork sheet is one square meter (10.76 square feet), so it makes it easy to figure if you look at the store.
