How this calculator works
Every figure above comes from the formula below, applied to the assumptions listed. Nothing is looked up from a hidden table — you can reproduce the result by hand.
Formula
deck area = length × width
decking cost = area × material rate per sq ft × height multiplier
railing = lineal feet of open side × $25–$60 per ft
total = decking + railing, split about 45% materials / 55% labour
Assumptions & limits
- TimberTech is costed at $30–$62 per sq ft installed. The range spans two different product families: capped composite at the lower end, capped polymer (PVC) at the upper.
- Because TimberTech sells both composite and PVC lines, the material choice inside the brand moves the price more than deck size does — pick the line before you trust a per-sq-ft figure.
- Board widths are nominally 5.5 in, and the maker's own spacing and gapping instructions govern joist spacing rather than generic wood-decking practice.
- Installed rates per sq ft: pressure-treated $15–$25, cedar or redwood $20–$35, composite $30–$60, PVC $35–$70, tropical hardwood $30–$60 (2026 US national ranges).
- Height multiplier is 1.0 ground level, 1.15 raised, 1.30 elevated, covering taller footings, beams, bracing and guard railing.
- Railing length is derived from the number of open sides: two sides = length + width, three = length + 2 × width, four = full perimeter.
- Labour is taken as roughly 55% of the installed figure — so the DIY materials-only line is about 45%.
- Excluded: stairs, built-in benches, lighting, pergolas, multi-level framing, permit fees and any ledger or footing work driven by local code.
Worked example
A 16 × 12 ft ground-level TimberTech deck with railing on three open sides
- Area = 16 × 12 = 192 sq ft
- Decking = 192 × $30 to $62 × 1.0 = $5,760 to $11,904
- Railing = 16 + 2 × 12 = 40 lineal ft × $25 to $60 = $1,000 to $2,400
- Total = $6,760 to $14,304
Result:About $6,760 to $14,304 installed in TimberTech — roughly $55 per sq ft at the midpoint.

How much does a TimberTech deck cost?
TimberTech makes both capped composite and capped polymer (PVC) decking. It sits alongside Trex as a premium, low-maintenance choice, with the PVC lines costing a bit more than the composite ones. Total cost turns on the collection you pick, the deck size and any railing and stairs.
As an installed all-in figure, TimberTech decking typically runs $30–$62 per square foot. On a 320 sq ft deck (16×20 ft) that is roughly $9,500–$20,000, before railing and stairs. The estimate above lets you set your size, height and railing to tighten the range.
cost = area × $30–$62/sq ft (× height) + railing length × rail rate

Frequently asked questions
How much does a TimberTech deck cost?
TimberTech composite/PVC decking typically runs $30–$62 per square foot installed. On a 320 sq ft deck (16×20 ft) that is roughly $9,500–$20,000, before railing and stairs. TimberTech makes both capped composite and capped polymer (PVC) decking. Enter your own size above for an estimate.
Is TimberTech worth the extra cost over wood?
TimberTech costs more up front than pressure-treated wood, but it resists rot, fading and stains and needs little upkeep, so it can be cheaper over the deck's life. Whether that trade-off is worth it depends on how long you'll keep the deck and how much maintenance you want to avoid.
What is the difference between TimberTech composite and AZEK?
TimberTech sells two different materials under one roof: capped composite lines with a wood-polymer core, and the AZEK line in capped PVC with no wood content at all. The PVC is lighter, the most moisture-resistant option in the family and the most expensive — which is why the brand's range runs all the way from $30 to about $62 per square foot installed.
Which TimberTech collection moves the price most?
The collection, not the deck size. Entry capped composite sits at the bottom of the range, the Pro-tier composites mid-field, and the AZEK PVC lines at the top. Before trusting any per-square-foot figure — including this calculator's — decide which collection you are actually pricing, then set the range accordingly.
Should I buy TimberTech or Trex?
They are direct competitors with overlapping prices and comparable capped-composite construction, so the honest answer is: decide on the board you like looking at, local availability, and the warranty terms — not on brand mythology. Both require tighter joist spacing than wood decking (16 in on center for perpendicular installs), which the framing budget needs to reflect.
Do I need a permit to build a deck?
In most US jurisdictions, yes — any deck attached to the house, or a freestanding deck above a certain height or size (often around 30 inches high or 200 square feet), needs a building permit and at least one inspection. Permit fees commonly run $50 to $500, and larger or engineered decks cost more. Building without a required permit can mean fines, a forced rebuild, or trouble when you sell the home, so check with your local building department before you start.
