Excavation & Earthwork
Excavation Cost Guide (2026)
Residential excavation costs $50-$200 per cubic yard or $100-$250 per machine-hour in 2026. Rates for grading, trenching, and hauling, plus what drives quotes up or down.
Excavation quotes confuse people because contractors price the same job three different ways: by the cubic yard, by the machine-hour, or by the project. All three are the same math underneath: machine time plus operator plus disposal. Here is how the 2026 rates break down and how to convert any quote into a number you can compare.
2026 rates by pricing method
| Pricing method | 2026 rate | Best for |
|---|---|---|
| Per cubic yard, dig only | $50-$200 | Defined holes: basements, pools, pads |
| Per machine-hour (mid excavator + operator) | $100-$250 | Open-ended or mixed work |
| Grading, per ft² | $0.08-$2.00 | Regrading, drainage slopes, pads |
| Trenching, per linear ft | $4-$25+ | Utilities, French drains, footings |
| Spoil hauling, per yd³ | $8-$25 | Any job where dirt leaves the site |
Ranges from 2026 cost surveys including HomeGuide and Angi. Minimum charges are common: many operators have a half-day minimum ($400-$800) that dominates small jobs.
The volume trap: bank vs. loose yards
Digging is quoted on bank yards (soil in the ground); hauling is billed on loose yards (soil in the truck), and dug soil swells 12-50% by type. A 20-bank-yard basement dig in clay produces 26 loose yards to haul. Quotes that ignore swell understate disposal by a quarter or more. The excavation calculator computes both volumes from your dimensions and soil type; the mechanics are explained in the soil swell guide.
What moves a quote up
Soil and rock. Sand digs fast; wet clay sticks to everything and doubles cycle times; rock means hammering or blasting at several times the per-yard rate.
Access. A machine that must squeeze through a 6-foot gate is a mini excavator doing a big excavator's job, at many more hours. Fences, septic fields, and overhead wires all add time.
Disposal distance. If spoil cannot stay on site, every mile to the dump and every tipping fee lands on your invoice. Keeping usable fill on the property is the single biggest saver on many jobs.
Water. A high water table or a rainy week means pumping, matting, and slower work.
Worked example: French drain trench, 60 ft
- Trench 60 ft × 12 in × 24 in = 4.4 bank yd³
- Machine trenching at $8/ft: $480 (about half a day, consistent with the hourly rate)
- Spoil: 4.4 × 1.25 swell = 5.6 loose yd³; haul-away at $15/yd³: $84, or free if spread on site
- Dig subtotal: $480-$570, before stone, pipe, and fabric (priced in the French drain cost guide)
DIY vs. hiring the machine
A mini excavator rents for $250-$450 per day plus delivery, roughly the cost of 2-3 contractor hours. For open, shallow, utility-cleared digging, a careful first-timer gets acceptable results. Hire out anything deeper than 4 feet, anything near structures or slopes, and every job in unknown soil. Call 811 before either path, and read the trench-safety rules on our safety page: OSHA's 5-foot shoring threshold exists because trench collapses kill quickly and without warning.

Frequently Asked Questions
How much does excavation cost in 2026?
Residential excavation runs $50 to $200 per cubic yard including machine and operator, or $100 to $250 per hour for a mid-size excavator with operator. Hauling spoil away adds $8-$25 per cubic yard.
How much does it cost to grade a yard?
Land grading costs $0.08 to $2.00 per square foot. A typical 1,000-2,000 sq ft regrading project lands between $770 and $3,000 depending on cut depth, fill needs, and access.
How much does trenching cost per foot?
Machine trenching for utilities and drains typically runs $4 to $12 per linear foot for shallow trenches (under 3 ft) in normal soil, and $10-$25+ per foot for deeper trenches requiring shoring or rock work.
Why do excavation quotes vary so much?
Soil, access, and disposal. Rock or wet clay can triple machine time; a tight backyard forces smaller equipment and more hours; and whether spoil stays on site or gets hauled and dumped changes the total more than the digging itself.
Is it cheaper to rent an excavator myself?
A mini excavator rents for $250-$450 per day, so DIY digging can save real money on simple, open-access projects. Utility strikes, cave-ins, and machine damage are the risks; always call 811 first and skip DIY anywhere near foundations or depth over 4 feet.
