Why fiber cement costs what it does
Hardie sits above vinyl on price for good reasons: the boards are heavier, installation is more labor-intensive, and the material itself costs more per square. That premium buys fire resistance, impact resistance and a long warranty. This calculator makes the trade-off visible by splitting material from labor so you can weigh the up-front cost against the lifespan.
Set your rates, toggle removal if you're covering old siding, and read the range. The cost per square figure lets you compare Hardie bids to each other and to a vinyl alternative on equal footing.
A quick walk-through
Think of it as describing your house to the tool. First tell it what you're installing and in which units — that's the material dropdown and the feet/meters toggle. Then describe the walls: one row each for the front, back and sides, with the width, height and how many are the same.
Now the details that trip most people up. Any triangular gable goes in with its base and its height to the peak. Every window and door goes in as a size and a count so it's subtracted rather than covered. Last, choose how much waste to carry — 10% is the everyday figure — and, if you'd like a budget, add your labor and removal rates. Calculate, and read squares, panels, boxes, trim and cost in one place.

Data sources and limitations
Two kinds of numbers feed this tool. The geometry — areas, openings, squares, waste — is fixed arithmetic and as accurate as your tape. The material coverage and the cost estimates are planning values based on common manufacturer specifications and reported US installed pricing; they vary with product line, region and labor, which is why they appear as ranges. Treat the result as a solid starting point for budgeting and ordering, subject to a field measure and your contractor's quote.
What moves a Hardie price up or down
Fiber cement's price is less about the boards and more about the labor and finish choices around them. If your quote feels high or low, one of these is usually why.
- Pre-finished vs primed: ColorPlus costs more per board but removes field painting. Primed is cheaper up front but you pay a painter later.
- Wall height and access: two-story and steep walls need staging and slow the crew, raising labor more than the material.
- Removal and repairs: stripping old siding and fixing sheathing underneath are separate lines that a bare 'per square foot' number hides.
- Trim density: lots of windows, corners and a busy trim package add both material and hours.
Set these in the cost inputs above and compare the range against your bids square by square.
