About Figuring Asphalt

We built the asphalt calculator we wished existed — fast, transparent, and free for everyone.

Our Mission

Figuring Asphalt exists to make paving math accessible to everyone. Whether you are a homeowner planning a driveway replacement or a contractor preparing a bid, you deserve clear numbers backed by real formulas — not hidden calculations or vague estimates.

What We Offer

Our free asphalt calculator estimates tonnage, coverage, cubic yards, and optional material cost for any rectangular paved area. Every result includes a step-by-step formula breakdown so you can verify the math yourself.

Who We Serve

  • Homeowners planning driveway or patio paving projects
  • Contractors and estimators who need quick, repeatable material calculations
  • Students and DIY learners studying construction and paving math

Our Approach to Accuracy

We use industry-standard asphalt density values (approximately 145 pounds per cubic foot for hot mix asphalt) and recommend a 5–10% waste factor to account for compaction and spillage. Final material requirements always depend on your local mix, site conditions, and compaction methods — so we encourage users to confirm estimates with their asphalt supplier or paving contractor.

Transparency & Trust

Figuring Asphalt is an independent educational resource. We are not affiliated with any asphalt supplier or paving company. Our goal is to provide helpful, unbiased tools and information. Read our Disclaimer and Privacy Policy for more details.
