Side-by-side comparisons and by-size cost breakdowns for the decisions homeowners actually face — upfront install price, lifespan, maintenance, and the 10-year math — with every figure reconciled to the matching calculator. No email gates, no lead forms.
The cheapest water heater to buy is rarely the cheapest to own. How the three main types compare on install price ($2,700–$12,400 installed), lifespan (10–20+ years), and running cost — and which one wins over a 10-year horizon for your fuel type and space.
PT lumber is cheaper upfront ($9,000–$15,400 vs $9,200–$17,100 for a 12×16 deck installed) — a smaller gap than most expect — and staining and sealing erase it within a few years of paid maintenance. The upfront price, the maintenance math, and when each material actually wins.
Installed 2026 price ranges for the ten most-built deck sizes — from a 10×10 at $5,800–$9,900 to a 20×24 at $18,300–$31,400 — in PT, composite, and PVC, plus why a small deck costs more per square foot than a big one.
Replacing furnace and AC together? A same-size heat pump installs for slightly less ($8,100–$14,200 vs $9,300–$16,600 at 3-ton) and burns no fuel. How climate, local energy prices, cold-climate performance, and the dual-fuel middle path decide which one actually costs less to own.
Standing-seam metal costs roughly 1.7× architectural asphalt upfront ($23,500–$38,100 vs $14,000–$20,000 on a 2,000 sq ft home) but lasts 50+ years against about 30. The long-horizon math on when one metal roof beats two asphalt ones.
LVP costs well under half as much as solid hardwood ($8–$13/sf vs $18–$30/sf all-in) and is fully waterproof; hardwood outlasts it because you can refinish it. Which wins by room, by budget, and by how long you're staying.
The two premium stone counters cost within about 5% of each other installed ($5,800–$10,000 quartz vs $5,500–$9,400 granite for a 40 sq ft kitchen) — so the real decision is upkeep, not price. Quartz never needs sealing; granite is heat-proof natural stone that wants an annual seal.
Installed 2026 ranges by wall area and material — vinyl ($20,600–$33,700 on a 2,000 sq ft wall) through fiber cement, cedar, stucco, metal, and brick — plus what tear-off, stories, and trim add.
Installed 2026 ranges by number of windows and frame material — 10 vinyl windows run $10,500–$18,400 (about $1,050–$1,840 each), fiberglass and wood 35–40% more — plus insert vs full-frame.
Installed 2026 ranges by tank size and fuel — a common 50-gallon gas or electric tank runs $2,700–$5,050 including code upgrades — and where a tankless or heat-pump upgrade changes the math.
Installed 2026 ranges from a 10×10 pad ($2,250–$3,550) to a 30×40 shop floor ($11,400–$18,550), in 4-inch and 6-inch, plus why small slabs cost far more per square foot.
Installed 2026 kitchen prices for the six mainstream surfaces — laminate ($3,600–$6,100) through quartz ($5,800–$10,000) to quartzite ($8,100–$14,000) — and why the labor barely changes between them.
Installed 2026 ranges by size — an 8 kW standby runs $9,600–$16,900, a common 14 kW $11,200–$19,500, a 22 kW $13,400–$23,300 — plus what size you actually need and standby vs portable.
The two cost nearly the same to pour ($7,700–$13,500 asphalt vs $7,900–$12,700 concrete for a 2-car drive) — so it’s a lifespan and maintenance decision. The upkeep math, by climate.
A tornado analysis across all 52 cost engines: size or quantity is the widest cost driver in 77% of projects, material grade in only 10%. Plus the 2.0x regional labor spread, trade minimums, and the 18–30% markup band.
Hold the specification identical and cut the footprint to a quarter, and the per-unit price rose in all 12 trades we could measure — a median of 1.84x. Where the money goes: trade minimums ($250–$1,500), trip charges ($175–$500), and setup that doesn’t scale down.
Markup runs 18–30% across every trade, so it explains about 10% of a quote gap at most. On a real 400 sq ft slab, the omittable scope — base, rebar, permit, vapor barrier, control joints — is 32% of the price. The five causes, ranked.
Once you have a planning range, this printable 10-point checklist helps you read the actual bid — scope, materials, permits, payment schedule, warranty, insurance, change orders — and spot the red flags before you sign.
