How much does big a joist 12" 12g cost?
Contractors are currently paying $7.76 to $8.26 per ft, with a median of $8.05. That range is the middle half of actual invoiced prices over the last 12 months — the cheapest and most expensive outliers are excluded, because one mis-keyed line item shouldn't define what you think a fair price is.
If you're paying above $8.26 per ft, you're in the top quarter of what other contractors pay for the same item — worth a conversation with your supplier.
What drives the price
- Size and material. The single biggest factor, and why we price at this level of detail rather than lumping every generic together.
- Supplier. The same item routinely differs by 15–20% between suppliers in one market. This range spans 4 of them.
- Order volume. Counter pickups price differently from a scheduled bulk delivery.
- When you bought. Prices drift. This is a trailing 12-month window, so it reflects the current market rather than a historical average.

How we know this
These figures come from real invoices processed through CostCrunch, not list prices or survey data. We normalise each line to a price per unit, exclude the top and bottom 1% as outliers, and a figure is only published once there are at least 10 purchases of that item in the last 12 months. Where a figure rests on a single supplier or a single company we say so, because that is one buyer's experience rather than a market rate — below that, an average says more about one buyer than about the market.
Check your own invoices against these prices — CostCrunch reads every line item and flags anything above market.
