Porch Calculator
Estimate covered porch costs — deck structure, posts, footings, roof (shingle, metal, or polycarbonate), ceiling, railing, and steps.
This is an estimate, not a bid or contract. Every job has unique conditions — access, structure, moisture, code — that software cannot account for.
Use at your own risk. Pinnacle Designs, LLC is not liable for bids, losses, or code compliance based on calculator output. You are responsible for verifying all numbers before use.
Terms of Service (limitation of liability & your responsibilities)
Always verify local building codes. Supplier prices vary by region. Add waste for cuts, mistakes, and damaged material.
Job Site Market (ZIP & Region)
Enter the job ZIP — not your shop — to load typical local labor and material defaults. Useful when bidding out of town or out of state.
Most U.S. ZIPs auto-select a region. Unknown ZIPs — pick the closest market manually.
Typical U.S. contractor rates, loaded ~5% above market average — adjust for your bid.
National Average — typical contractor labor ~$57.75/hr
Typical labor rates align with the national average.
Defaults load ~5% above typical market averages — a conservative benchmark when clients compare your bid. Edit any rate below for your actual numbers.
Regional defaults update labor, materials, markup, and tax in this calculator. Your job ZIP and region are saved across all calculators — change ZIP when you switch to a different job site.

Estimate — not a bid
Numbers from this tool are planning estimates only. They are not a contract, quote, binding bid, or professional advice. Every job carries its own challenges — hidden damage, tight access, moisture, local code, and scope details — that no calculator can see.
Each project is different. Access, existing conditions, code requirements, material choices, and your local market all affect the final price. Use these figures as a starting point — your actual price may vary.
By using this tool you agree you will not rely on it as a final bid without your own verification. See our Terms of Service for limitations of liability and your responsibilities.
