  • Hardware & fastener counts
  • Stairs & railings add-on
  • Cost estimates for 5 species
  • Waste factor by pattern

Deck Cost Calculator

Estimate total project cost by material

Compare decking material and labor costs side by side for 10+ materials. Enter your deck size, choose a wood species or composite, and get instant per-square-foot pricing for materials only or a fully installed deck.

  • 10 material types
  • Material vs. labor breakdown
  • Per-sq-ft pricing
  • Framing & hardware included

Board Foot Calculator

Calculate board footage for ordering

Board feet are the standard unit for buying hardwood lumber. Enter thickness, width, length, and quantity to instantly calculate total board footage for accurate pricing and ordering from any supplier.

  • Instant BF calculation
  • Per-piece & total BF
  • Formula reference
  • Quantity support

Stair Calculator

Rise, run, and materials for stairs

Design code-compliant residential stairs. Enter total rise, choose a target step height, and get the number of risers, tread depth, stringer length, angle, and a materials list — with IRC 2018 building code compliance checking.

  • IRC 2018 code checking
  • Rise & run calculations
  • Stringer length & angle
  • Material list
  • Multiple stringer sizes

Flooring Calculator

Hardwood flooring material estimates

Calculate exactly how much hardwood flooring to order. Accounts for room dimensions, board size, layout pattern (straight, diagonal, herringbone, chevron), waste factor, underlayment, transitions, and baseboard trim.

  • 4 layout patterns
  • Waste factor by pattern
  • Underlayment & transitions
  • Baseboard trim estimate
  • Fastener counts

Cut List Generator

Optimize cuts and reduce waste

Reduce material waste and save money. Enter the cuts you need and your stock board length — the optimizer packs cuts efficiently using a First Fit Decreasing algorithm and tells you exactly how many boards to buy. Export your cut list.

  • FFD optimization algorithm
  • Waste percentage tracking
  • Board-by-board instructions
  • Export to text file
  • Multiple stock lengths

Material & Cut Calculator

Quick deck board estimator

A fast way to estimate deck board and fastener counts from your deck dimensions. Supports both fixed-length and random-length lumber — perfect for exotic hardwood orders where boards arrive in varying lengths.

  • Fixed & random lengths
  • Board count & linear feet
  • Fastener estimates
  • Multiple board widths

Which Calculator Do I Need?

Building a Deck?

Start with the Advanced Deck Estimator for a complete material takeoff, then use the Deck Cost Calculator to compare prices across wood species. If you need stairs, the Stair Calculator ensures code compliance.

Installing Hardwood Floors?

The Flooring Calculator handles waste factors for straight, diagonal, herringbone, and chevron patterns. Use the Board Foot Calculator if you're ordering unfinished hardwood by the board foot.

Ordering Lumber or Hardwood?

The Board Foot Calculator converts dimensions to the standard pricing unit for hardwood. Then use the Cut List Generator to optimize how you cut each board and minimize expensive waste.

Quick Estimate?

The Material & Cut Calculator gives you a fast board count and fastener estimate — perfect for early-stage planning before you commit to a detailed takeoff.
