Build vs Buy: The True Cost of DIY Furniture
DIY furniture can save 40-70% vs retail, but only if you factor lumber, waste, finish, and your time. This calculator compares your build cost to retail and shows your effective hourly rate.
About This Calculator: Furniture Building & Woodworking Cost
Why: DIY furniture can save big, but only if you know the true cost. Lumber, waste, finish, and time add up. This calculator helps you decide: build or buy?
How: We use board-foot pricing by species, finish cost per sqft, and optional hourly wage to compute total project cost, build vs buy savings, and effective hourly rate.

DIY furniture can save 40-70% vs retail for comparable quality. Wood costs range from pine at $3.50/board foot to walnut at $14/BF. Finish adds $0.50-$1.50/sqft. The key question: does your build cost plus time value beat the retail price? This calculator helps you decide before you start.

Key Takeaways
- • Lumber is usually 50-70% of project cost; wood choice drives the budget.
- • Add 10-20% waste factor for cuts, defects, and mistakes.
- • For painted pieces, use pine or poplar; for stained, oak or maple.
- • Factor your time: if (materials + hours × wage) > retail, buying may be smarter.
Did You Know?
How Does Furniture Cost Calculation Work?
Lumber Cost
Board feet × (1 + waste factor / 100) × price per BF. Waste covers cuts, defects, and mistakes. Pine $3.50/BF, oak $8.50/BF, walnut $14/BF.
Finish Cost
Finish area (sqft) × cost per sqft. Stain+poly $0.80, paint $0.50, oil $1.20, lacquer $1.50. Food-safe projects use mineral or tung oil.
Build vs Buy & Time Value
Savings = retail price − total project cost. Effective hourly rate = savings ÷ build hours. Time-valued cost = materials + (hours × hourly wage). If time-valued cost > retail, buying may be better.

Frequently Asked Questions
How much does it cost to build furniture vs buy it?
DIY furniture typically costs 40-70% less than retail for comparable quality. A farmhouse table you build for $400-$600 might retail for $1,200+. Savings depend on wood species, finish, and whether you value your time. Use this calculator to compare your project cost to retail before starting.
What is a board foot and how do I calculate it?
A board foot (BF) is 1 foot × 1 foot × 1 inch of lumber. For a board 6 ft × 6 in × 1 in: (6 × 0.5 × 1) = 3 BF. Add 10-20% waste for cuts and defects. Our Board Foot Calculator can help you estimate lumber needs for your project.
Which wood species is cheapest for DIY furniture?
Pine ($3.50/BF) and poplar ($4.50/BF) are the most affordable. Oak ($8.50/BF) and maple ($9/BF) are mid-range. Walnut ($14/BF) and cherry ($11/BF) are premium. For painted pieces, pine or poplar saves money; for stained pieces, oak or maple offer good value.
How much does wood finish cost per square foot?
Stain + poly: ~$0.80/sqft. Paint: ~$0.50/sqft. Oil (Danish, tung, mineral): ~$1.20/sqft. Lacquer: ~$1.50/sqft. None: $0. Finish cost adds up on large surfaces—a 30 sqft table at $1.20/sqft is $36 in finish alone.
When is it worth building furniture instead of buying?
Build when: (1) retail equivalent costs 2x+ your materials, (2) you enjoy the process, (3) you need custom dimensions, or (4) your effective hourly rate (savings ÷ hours) exceeds what you'd pay for your time elsewhere. If your time-valued cost exceeds retail, buy instead.
How do I factor in my time when comparing build vs buy?
Enter your hourly wage in the calculator. It adds (build hours × wage) to your project cost. If time-valued cost exceeds retail price, buying may be smarter. If you build for hobby value, leave wage at $0 to see pure materials savings.
