About this path
- How accurate are DeckMath cost estimates?
- Material costs are accurate within ±5% for most ZIP regions, using 2026 retail prices from Home Depot, Lowe's, and manufacturer MSRPs. Labor estimates use NAHB national averages.
- What's the average cost to build a deck in 2026?

- Should I use the Deck Cost Calculator or a brand-specific one?
- Use the general Deck Cost Calculator for a quick estimate across materials. Use a brand-specific calculator (Trex, TimberTech, Fiberon, Azek) when you've decided on a product line — brand calculators include exact SKU pricing, hidden-fastener box counts, and warranty notes.
- Do DeckMath cost calculators include permits?
- The full Deck Cost Calculator includes permit cost as an optional line item. For a permit-only estimate, use the dedicated Deck Permit Cost Calculator with your state and project value.
