Calculate deck cost from area, material per sq ft and labor — see total cost with railing and stairs.
Enter values above and click Calculate — results will appear here with the formula explained.
Deck cost is area times material plus labor per sq ft, plus railing and stairs. Wood $10-20, composite $20-35, labor $8-15 per sq ft.
Railing adds $20-40 per linear foot, stairs $300-800. Add permit $200-500 not included.
For YMYL, composite costs more but lasts 25y vs wood 10-15y with maintenance.
To use the Deck Cost Calculator, enter deck area (sq ft), material per sq ft, labor per sq ft above for an instant result with full breakdown and formula (Total = area*(material+labor) + extras). Adjust values live to compare scenarios, then check the worked example and FAQs below for practical tips and costly mistakes to avoid.
Calculate deck cost from area, material per sq ft and labor — see total cost with railing and stairs. Formula: Total = area*(material+labor) + extras. Example: With 300 sq ft, $15 material, $10 labor, $1,500 extras: cost 300*25=$7,500 + $1,500 = $9,000.
