Carpet Cost Calculator

Carpet is manufactured in large, standard-width rolls (usually 12 or 15 feet wide). Unless your room is exactly that width, installers have to cut the roll and seam pieces together to cover your floor. The standard 10% overage covers these trimmed offcuts to ensure you don't run short. If you are installing carpet on stairs or choosing a carpet type with a complex repeating pattern, your waste factor might actually jump to 15% or 20% to accommodate the precise matching required.

Yes, in almost all cases. Carpet padding (also known as underlay) breaks down over time, absorbs spills, and holds onto odors. Furthermore, most carpet manufacturers will actually void the warranty on your brand new flooring if it is installed over old padding, as a fresh cushion is essential for extending the life and comfort of your new carpet.

No, stairs require significantly more labor and time. Installers have to carefully cut, stretch, and staple the material around every single tread and riser, rather than just laying it flat across a large square footage. Usually, a professional quote will list a flat additional fee per stair (e.g., $10 - $25 per step) on top of the standard material cost. You can easily add this into the "Additional Fees" section of our carpet installation cost calculator.

Absolutely. Installers generally charge between $0.50 and $2.00 per square foot for "rip up and haul away." If you have the time, a utility knife, and a vehicle to take the old materials to the dump, performing the removal yourself is a highly effective way to significantly reduce your total installation cost.

Generally, a standard carpet type like plush, berber, or frieze will cost about the same to install. However, heavily patterned carpets that require precise matching at the seams, or very thick, high-end carpets, can sometimes incur a higher labor rate due to the extra time, planning, and care required during installation.

Installers require the room to be clear of all small items, electronics, and breakables. While many flooring companies will move large furniture (like beds, dressers, or couches) for an additional fee added to your final quote, moving the furniture yourself before they arrive is a common way to lower your total project cost.

In most standard installations, baseboards do not need to be removed. Carpet installers use specialized tools to stretch and tuck the edges of the carpet neatly underneath your existing baseboards. Only if the baseboards are installed completely flush with the subfloor might they require removal or adjustment.

A transition is a strip (often made of metal, wood, or heavy-duty plastic) used to bridge the gap where your new carpet meets a different type of flooring, such as tile or hardwood. Installers typically charge a small fee per transition strip or per linear foot, which you can account for in the "Miscellaneous Fees" section of our calculator.
