Calculate carpet cost from area, price per sq ft and pad — see material, pad and total with install.
Enter values above and click Calculate — results will appear here with the formula explained.
Carpet cost is area times the stacked per-sq-ft rate: material ($2–6) plus pad ($0.50–1) plus install ($1–2), totaling $3.50–9 installed. A 500 sq ft job at $3.50 carpet, $0.70 pad and $1 install lands at $2,600 — the arithmetic is simple, but each layer hides choices that swing the total 30%.
Material tiers map to fiber and density: polyester $2–3 (soft, stains, mats fast), nylon $3–5 (resilient, best value for traffic), wool $6+ (luxury, long life). Face weight (oz per sq yd) matters more than thickness — dense 40 oz nylon outlasts fluffy 60 oz polyester. Buy density, not pile height.
Padding is the highest-ROI line: 7/16-inch 8-lb rebond (~$0.70/sq ft) doubles carpet life versus thin foam, improves feel dramatically, and most manufacturer warranties require minimum pad specs — skimping here voids coverage. Upgrading pad beats upgrading carpet dollar for dollar.
Waste and seams: add 5–10% for straight runs, 10–15% for pattern matching and stairs (each tread wastes nosing cuts). Measure rooms, add closets separately, and never let installers 'round up' bulk — waste over 15% on rectangles is padding the invoice.
Install quotes decode as: basic stretch-in $1–1.50, furniture moving $1–2 per piece or flat $100–200, old carpet rip-out and disposal $0.50–1, transitions and tack strips often 'included' until they aren't. Get line-item quotes from two installers; bundled per-sq-ft figures hide $300–600 of extras.
Carpet versus hard flooring total cost must include lifespan: $4,000 carpet lasting 8–10 years costs more per year than $7,000 LVP lasting 25. Rentals and kid zones favor cheap carpet replaced often; forever homes favor hard surfaces with area rugs.
Calculate carpet cost from area, price per sq ft and pad — see material, pad and total with install. Formula: Total = area*(price+pad+install). Example: With 500 sq ft, $3.50 carpet, $0.70 pad, $1 install: 500×$5.20 = $2,600.

With 500 sq ft, $3.50 carpet, $0.70 pad, $1 install: 500×$5.20 = $2,600. Upgrading pad to $1 (+$150 total) extends carpet life years; upgrading carpet to $6 (+$1,250) with cheap pad shortens it — the pad dollar wins.
