FAQ
Frequently Asked Questions
Everything you need to know about ConstructlyTools and our free calculators.
Are all the calculators on ConstructlyTools free?
Yes — every calculator and guide on ConstructlyTools is 100% free with no signup, no subscription, and no hidden fees. All 90+ tools are free to use on any device, any time.
How accurate are the cost estimates?
Our cost calculators use 2026 US national average pricing from RSMeans unit cost data, HomeAdvisor/Angi completed project surveys, and NAHB construction cost reports. For most projects, estimates land within 15–25% of actual contractor quotes in average US markets. In high-cost regions (Pacific Coast, Northeast), add 25–40%. Always use our estimates as a starting range and get 3 itemized contractor quotes before committing to any project over $5,000.
Do the material calculators include waste factors?
Yes — every material calculator applies industry-standard waste factors automatically. Concrete: 10% for pour waste. Tile: 10–20% depending on layout complexity. Rebar: 10% for lap splice overlap. Drywall: selectable 10–20%. You never need to add waste manually — it's built in and shown clearly in the results.
Can contractors use ConstructlyTools too?
Absolutely. Our tools are designed for both homeowners and contractors. The cost calculators include separate DIY vs contractor pricing, regional multipliers, and a Copy Result button so you can share estimates with clients or save them for project files. Many contractors use ConstructlyTools for quick field estimates during site visits.
How often is the pricing data updated?
All cost estimators are reviewed and updated annually. Current pricing reflects 2026 US averages incorporating recent material cost changes and labor rate trends. If you're planning a project more than 6 months out, add a 5–10% contingency buffer to account for potential price movement.
