Why takeoff & calculator with LaraKey is different.
A calculator that speaks construction
Feet, inch, yard and meter keys, fractions down to 1/64″, squares and roots, memory and a tape of every answer. Lengths multiply into areas and volumes, and results show in feet-inch-fractions.
- Type it the way you say it: 12′ 6 1/2″
- Convert to ft, in, yd, m, cm, mm or acres
- Round display to 1/2″ … 1/64″, full precision kept
- Saved sessions you can name and link to a job
Quick takeoffs in seconds
Drywall sheets (4×8 to 4×12), LVP or tile boxes, carpet by the square yard, and paint by coats and coverage. Pick waste, and LaraKey shows the math and what to buy.
- 600 sq ft ÷ 32 sq ft per sheet = buy 19 sheets
- Paint split into 5-gallon buckets plus gallons
- Approximate cost from your catalog prices
- Build a room-by-room list, copy or save it
Measured takeoffs for drywall, LVP and tile
Measure walls, ceilings and rooms (rectangles, triangles, circles), take out doors, windows and cabinets, choose one or both sides and layers. LaraKey works out net area, waste, exact and purchase units, and cost.
- Several materials per takeoff
- Tile counted by tile size and tiles per box
- Numbered revisions with history
- “How it’s worked out” shows the formula
Into the estimate, out to the supplier
Add a takeoff to a draft estimate as material lines, and update them later without touching the labor you added. Export the material list as CSV or print it for the supplier.
- “Add to estimate” and “Update estimate”
- Warning if the estimate has an older revision
- CSV with SKU, supplier, waste and units
- A material catalog with your products and prices

Takeoff & Calculator: common questions
Which materials have measured takeoffs?
Drywall, LVP and tile have measured takeoffs. Carpet and paint are covered by quick takeoffs.
How is waste handled?
Waste is added to the net area before dividing by coverage, and the result is rounded up to whole purchase units only at the end.
