About this calculator
Carpet is sold and installed by the square yard in the US trade, which trips up a lot of homeowners measuring in square feet — this calculator converts your room square footage automatically. Total cost combines a carpet material rate (which varies enormously by fiber type, from budget polyester to premium wool), a separate padding rate since pad is priced and sold independently of the carpet itself, and an installation labor rate that covers tack strip, seaming, stretching, and old-carpet removal. 2026 US national averages run about $3-$7 per square foot for mid-range carpet plus pad, or roughly $27-$63 per square yard, with installation labor adding $1-$2 per square foot on top. A 10% waste factor is standard to account for pattern matching and room shape, and removal/haul-away of old carpet typically adds a modest flat fee if not already included in the installer's quote.

- The carpet material rate used in the calculation, measured in $/sq yd. Starts at 30 $/sq yd so you have a working example on load. Accepted range: 10–120 $/sq yd.
- Padding rate ($/sq yd)
- The padding rate used in the calculation, measured in $/sq yd. Starts at 6 $/sq yd so you have a working example on load. Accepted range: 2–20 $/sq yd.
- Installation labor ($/sq ft)
- The installation labor used in the calculation, measured in $/sq ft. Starts at 1.25 $/sq ft so you have a working example on load. Accepted range: 0.5–4 $/sq ft.
- Old carpet removal + haul-away ($)
- The old carpet removal + haul-away used in the calculation, measured in $. Starts at 150 $ so you have a working example on load. Accepted range: 0–800 $.
- Waste / pattern-match allowance (%)
- The waste / pattern-match allowance used in the calculation, measured in %. Starts at 10 % so you have a working example on load. Accepted range: 0–25 %.

FAQ
Why is carpet priced by the square yard instead of square foot?
Carpet is manufactured and sold in rolls typically 12 feet wide, and the flooring trade has historically priced and ordered material by the square yard as a result — this calculator converts your square footage automatically so you don't have to do the math.
Do I really need new padding, or can I reuse the old pad?
Padding compresses and loses its cushioning within 8-10 years and should almost always be replaced with new carpet — reusing old, compressed pad under new carpet leads to faster wear and voids many manufacturer warranties.
How much waste should I plan for on a carpet job?
A standard 10% waste allowance covers most rectangular rooms, but rooms with lots of closets, angles, or a carpet pattern that needs to be matched across seams can require 15-20% extra material — ask your installer to measure before finalizing your order.
Does removing old carpet cost extra?
Most installers either include basic old-carpet removal in their quote or charge a modest flat fee ($1-$2 per sq ft, often bundled as a flat $100-$300 charge) for pulling up and hauling away the old carpet and pad — always confirm whether it's included before comparing quotes.
Accuracy and limitations
- Results are estimates before tax, fees, and inflation unless an input explicitly covers them.
- Rates are treated as fixed for the whole period — variable-rate products will drift from this projection.
- This is educational maths, not financial advice. Check anything contractual with the lender or your accountant.
