Deck Cost Estimator
Estimate the cost of building a deck from its size and materials.
Budgeting a deck
A deck's cost comes down to its area, the decking material you choose, and the supporting structure and labour. This estimates the total from those inputs, so you can budget a project and compare the cost of different materials before committing.
Enter the deck size and material to see an estimated cost.
Where the money actually goes
A couple of realities shape a deck budget. The decking surface is the visible cost, but the frame beneath, the footings, fixings and finishing add up, and labour is often a large share if you are not building it yourself. Material choice drives a big swing — budget timber is cheap upfront but needs ongoing treatment, while composite costs far more initially and almost nothing to maintain, so the cheaper option is not always cheaper over years.
Frequently asked questions
What drives the cost of a deck most?
The material choice and the area, plus the structure beneath and labour, which is often a large share if you do not build it yourself.
Is cheaper decking actually cheaper?
Not always over time — budget timber costs less upfront but needs ongoing treatment, while composite costs more initially but almost nothing to maintain.
Is this an exact price?
No — it is a planning estimate. Real costs vary with local prices, site conditions and design, so get quotes for the actual job.
