Siding Cost Calculator
See a realistic installed siding cost for any material — the money split into material, labor and removal, with a low-to-high range.

Tip: measure each wall's width × height at its widest points. A per-wall audit table appears below so you can check every number.
Your siding squares, panels and cost appear here.

What goes into a siding price
A siding price is really four numbers stacked together: the material, the crew's labor, tearing off and hauling the old siding, and a contingency for the surprises every remodel hides. Lump them into one per-square-foot figure and you lose the ability to question a quote. Break them apart — which is what this calculator does — and you can see exactly where a bid is high or where you can trim.
Choose your material for a sensible starting price, set labor and removal to match your market, and read the range. The likely figure is your baseline; low and high account for region and complexity.
How to fill it in (and what each field does)
Every field maps to a real measurement, so if you can read a tape you can use this. Walk through it top to bottom:
- Units + material: feet or meters, then the product you're installing — this sets coverage and a starting price.
- Walls: add a row per wall face with its width, height and count.
- Gables: base and rise for each triangle under the roof.
- Windows & doors: size and count for each, so their area is removed.
- Waste & cost: a percentage cushion plus optional labor and removal rates.
Hit calculate and the full breakdown appears below the form.
Siding calculator by material
Coverage and price change with the product. Pick the calculator tuned to what you're installing — each uses the same measuring engine with material-specific defaults.
A four-part price
| Component | Typical share |
|---|---|
| Material + trim | 40–55% |
| Labor | 35–45% |
| Removal + disposal | 5–15% |
| Contingency | built into the high band |
About the accuracy of these results
We'd rather be transparent than falsely precise. The quantity math is deterministic and matches standard takeoff practice, so if your inputs are right, your squares and piece counts are right. Where real-world variation lives — coverage by profile, and installed cost by region and crew — we use typical published figures and present them as ranges. That makes this a strong planning number, not a binding quote; a contractor's field measure remains the final word.
Turning an estimate into a real budget
A materials-plus-labor range is the core of a budget, but a project has a few more costs worth pencilling in so nothing blindsides you later.
- Permits: many areas require a permit for re-siding. It's usually modest but real.
- Repairs underneath: once old siding is off, rotted sheathing or bad flashing sometimes appears. A small contingency covers it.
- Disposal fees: dumpster and landfill charges scale with how much you're tearing off.
- Trim, gutters, paint: re-siding is the ideal time to refresh these; bundle them into the budget while the crew is on site.
Add a 10–15% contingency on top of the range above and your budget will hold up when the first surprise appears.
