What Is the Excavation Cost Calculator?
The Excavation Cost Calculator is a free online tool designed for contractors and DIY builders who need quick, accurate calculations in the construction and building space. By entering your length, width, depth, you get instant results including volume to excavate, truck loads, excavation cost. No formulas to memorize, no spreadsheets to build — just enter your numbers and get the answer in seconds. Whether you're a beginner or experienced professional, this calculator saves you time and eliminates guesswork.
Why This Calculation Matters
Getting volume to excavate right can make the difference between success and costly mistakes. In construction and building, small errors compound quickly. Manual calculations are error-prone and time-consuming, especially under pressure. This calculator applies proven formulas used by contractors and DIY builders worldwide, giving you confidence that your numbers are correct. Use it to plan your projects with precision and avoid common pitfalls that trip up beginners.
When Should You Use This Calculator?
This tool is most useful when you know your length and need to find the right volume to excavate. It's also great for quick estimates before committing to a decision, and to double-check manual calculations or professional quotes, and when comparing different scenarios side by side. Bookmark this page and come back whenever you need a fast, reliable answer — the calculator is always free and requires no signup.

How to Use This Calculator
- Enter Your Length (feet): Start by entering your length — this is the primary input for the calculation.
- Fill In Additional Details: Complete the remaining fields: width, depth, soil type, haul away dirt?. Each value refines the calculation for greater accuracy.
- Click Calculate: Hit the Calculate button to run the numbers. Results appear instantly below.
- Review Your Results: Check your volume to excavate, truck loads, excavation cost. Use these figures to inform your next decision or compare against alternative scenarios.
How It Works
This excavation cost calculator uses established formulas to provide accurate results.
The basic rule:
- Volume — Cubic Yards = (L x W x D) / 27 — Divide cubic feet by 27 to get cubic yards.
- Haul Volume — Haul CY = Excavated CY x 1.25 (swell factor) — Loose soil takes up 25% more space than in-ground soil.
Material prices and building codes vary by region. Get local quotes before purchasing.
Tips & Considerations
- Double-check your length before calculating — even small input errors can significantly change your results.
- Run the calculator with different values to compare scenarios and find the optimal approach for your situation.
- Pay attention to both volume to excavate and truck loads — they work together to give you the full picture.
- Bookmark this page for quick access next time you need to plan your projects.
- If you're unsure about your haul away dirt?, start with a conservative estimate and adjust from there.
Frequently Asked Questions
How much does excavation cost per cubic yard?
Typical excavation costs are $5-$10 per cubic yard for loose topsoil, $10-$15 for clay or compacted soil, and $20-$40 for rocky ground. These are digging-only costs; hauling adds $300-$500 per 10-yard truck load.
What is the swell factor for excavated soil?
Excavated soil expands 20-30% in volume (swell factor of 1.2-1.3) because it loosens when dug. A 100 cubic yard hole produces roughly 125 cubic yards of loose material to haul away.
Is the Excavation Cost Calculator free to use?
Yes, completely free with no signup required. Use it as many times as you need — there are no limits or hidden fees.
How accurate is this calculator?
This calculator uses standard construction and building formulas trusted by contractors and DIY builders. Results are reliable estimates for planning purposes. For critical decisions, we recommend consulting a qualified professional to verify.
What length should I enter?
Enter the most accurate length value you have available. If you're estimating, use a conservative figure. You can always run the calculator again with different values to see how changes affect the results.
