Interior Finish Calculators
Finish work is where waste factors decide the budget. A 10% cut allowance on tile, a pattern repeat on plank flooring or a single extra sheet of drywall moves the number more than the unit price does.
There are 10 calculators here: Kitchen Backsplash Tile Calculator (tile, thinset, grout and edge trim for a backsplash), Kitchen Cabinet Linear Foot & Cost Calculator (base and wall cabinet linear feet, and what they cost), Carpet & Pad Cost Calculator (square yards of carpet, pad and installed cost), Countertop Square Foot & Cost Calculator (countertop area, edge footage and fabricated cost), and 6 more below.
They all work the same way: quantity first, then a waste allowance you can change, then a price built from verified figures and adjusted for your state. Cost is always a range rather than a single number, and every assumption behind it is printed on the page with its source and the date it was last checked.

- Flooring CalculatorsThree flooring materials priced the way they are actually sold: carpet by the roll width, hardwood by the bundle, vinyl plank by the carton — each with its own waste and its own underlayment.3 calculators
- Tile CalculatorsTile quantity is area divided by tile size and then rounded up twice — once for cuts, once for the box. Wet areas add waterproofing that is priced by the roll, not the square foot.2 calculators
- Kitchen Remodel CalculatorsKitchens are quoted in linear feet of cabinet run and square feet of countertop, which is why a kitchen estimate rarely matches a floor-area estimate.2 calculators
- Drywall & Trim CalculatorsSheet goods and millwork: how many boards a room takes with the mud and tape that go with them, and how much trim a stair or a wainscot run consumes.3 calculators
