About us
MyAsphaltCalc is a free online calculator that turns your driveway, road or parking lot measurements into tons and dollars — in seconds, with no signup and no data capture.
Mission
Asphalt math should be simple.
Ordering asphalt is one of those tasks that seems straightforward until you are staring at a quote in tons and wondering whether it is right. Most people end up guessing, or calling a supplier only to be told "bring me your square footage."
We built MyAsphaltCalc to put that math back in your hands. Measure your surface, pick a shape and thickness, and the calculator works out area, volume, tonnage, waste allowance and cost — using the same density-based formulas contractors use, with every step shown so you can follow along.
We deliberately keep the tool free, browser-based and signup-free. Your measurements are yours — they are processed locally on your device and never uploaded, so the calculator works anywhere, even without an internet connection after the page loads.

Inside the calculator
What you get
Any shape, any unit
Rectangle, circle or triangle — measured in feet, yards, meters, centimeters or millimeters, with thickness entered in inches, feet, centimeters or meters. Density presets for hot mix, warm mix and cold mix, or enter your own.
Tonnage, waste and cost
See cubic volume, tons, an adjustable waste allowance (default 5%) and a material budget in your local currency — plus a practical order recommendation so you never under-order on delivery day.
The math, shown
Every formula is published on the homepage, from area and volume to the square-feet-times-inches-times-0.006 shortcut, with a full worked example so the result makes sense before you commit to it.
Guidance, not guesswork
A thickness guide for driveways, parking lots and truck traffic, cost factors to budget for, and an FAQ covering coverage per ton, pricing and common pitfalls.
