We are not guessing — every number comes from a verifiable source.
Our base cost figures are sourced from RSMeans, the construction industry standard for project cost estimation used by architects, engineers, and contractors across North America since 1942.
We supplement RSMeans data with real contractor quote data aggregated quarterly from across the US. This keeps our numbers grounded in what homeowners are actually being charged — not just theory.
Construction material prices — especially asphalt shingles (oil-linked) and lumber — shift significantly throughout the year. We update all cost data every quarter to reflect current market conditions.
We generate revenue through display advertising and affiliate links — never by charging contractors to appear in results or adjusting estimates to favor certain outcomes. Our data is independent.
Not just numbers — expert context on what drives costs, how to save money, and what to watch out for.
The complete guide to roofing costs — from 3-tab asphalt to natural slate. Includes state breakdowns, material comparisons, and the biggest factors that move the price.
What a $15,000 kitchen looks like vs a $45,000 kitchen — and how to decide which scope makes sense for your home value and goals.
Why HVAC quotes vary by $4,000+ for the same system size. The breakdown of equipment, labor, and the warranty fine print that matters most.
Independent reviews of estimating software for roofing, HVAC, and general contracting — with real pricing and honest tradeoffs.
Satellite roof measurements, instant proposals, and payment processing in one platform. Best for growing roofing companies.
Full project management plus estimating. Handles subcontractors, change orders, and client portals. Best for remodelers with 5+ active jobs.
Enterprise-grade field service management with flat-rate pricing books built in. The industry standard for large HVAC operations.
Our estimates are accurate to within 15-25% for most standard projects. We base every number on RSMeans cost data cross-referenced with 47,000+ real contractor quotes aggregated across the US. That accuracy level is close enough to budget confidently, evaluate contractor bids, and know if you are being quoted fairly — which is exactly what these tools are designed for.
The estimates are not a substitute for an on-site inspection by a licensed contractor, which can reveal hidden costs like structural damage, code upgrade requirements, or access challenges.
Yes, completely free. No signup, no email, no credit card. We generate revenue through display advertising and affiliate commissions when users choose to connect with contractors or purchase software through our links. This never influences our cost data, calculator results, or editorial recommendations — those are based entirely on actual market data.
All 50 US states. Every calculator includes a state selector that adjusts the estimate for regional labor cost differences. Hawaii and California consistently have the highest labor rates (30-55% above national average). Mississippi, Arkansas, and Alabama have the lowest (15-25% below national average). The national average is a reasonable starting point if you skip the state selector.
Every quarter. Construction material prices — especially asphalt shingles (oil-linked), lumber, and HVAC equipment (steel and copper-linked) — can shift 10-20% within a single year. Our Q1 2025 data reflects contractor pricing as of January 2025. Each calculator page displays its last update date clearly.
These calculators are designed for residential projects only. Commercial construction has fundamentally different cost structures — union labor requirements, commercial-grade specifications, different permitting processes, and longer project timelines all push costs significantly higher. For commercial projects, we recommend working with a licensed commercial estimator or using RSMeans directly.
