Quickly price spreading work using area, depth, and material density inputs today. Include setup, base prep, compaction, equipment, and minimum charges easily for accuracy.
| Scenario | Area (sq ft) | Depth (in) | Crew | Rate | Productivity | Estimated hours |
|---|---|---|---|---|---|---|
| Path refresh | 240 | 2 | 2 | 28 | 140 | 2.0 |
| Patio border | 420 | 3 | 3 | 30 | 150 | 2.6 |
| Driveway top-up | 900 | 2 | 4 | 32 | 160 | 3.3 |
In garden work, material often arrives in one load, but placement takes time. A 300–600 sq ft area commonly needs several crew-hours for moving, raking, and final grading. Tight access, wheelbarrow distances, and cleanup can add measurable labor even when gravel volume is modest.
Depth converts quickly to volume: Volume(ft³)=Area×Depth(ft), then yd³=ft³÷27. A typical 2-inch layer over 360 sq ft is about 2.22 yd³ before waste. Adding 5–10% overage helps cover uneven bases and minor spills.
Gravel density varies by rock type and moisture. Many landscape gravels fall around 1.25–1.50 tons per yd³. Tonnage is useful for comparing cost per ton and for aligning labor with handling effort, especially when spreading from a stockpile or driveway drop.
Productivity per worker can range widely. Light touch-ups on flat ground may exceed 180 sq ft/hr per worker, while heavy regrading, thick lifts, or obstacles may drop below 100. This calculator scales spreading time by crew size, helping you test “one-person” versus “two-person” scenarios.
Base preparation, raking, and compaction are separate activities with different pacing. A common planning approach is to assign crew-hours per 100 sq ft for each step. That structure makes it easy to reflect site conditions such as fabric installation, edging work, or compacting multiple lifts.
Plate compactors, skid steers, or powered wheelbarrows can reduce fatigue and improve finish quality, but they add hourly or fixed charges. Many crews only need equipment during placement and compaction. Estimating equipment hours against those phases keeps budgets realistic and transparent.
Service providers often include a trip fee for loading tools and travel. Small jobs may also have a minimum charge to cover overhead. Applying tax after the subtotal mirrors many invoices. Using these toggles helps you match estimates to local billing practices and avoid underpricing.
Use total cost for the headline, then reference crew time, person-hours, and optional tasks as supporting detail. Cost per sq ft is helpful for comparing alternatives like pavers or mulch, while cost per ton aligns with heavy material handling. Exporting CSV or PDF makes sharing fast.
Use dimensions when the space is rectangular and easy to measure. Use area when the shape is irregular and you already calculated total square footage from a sketch or site plan.
Many garden paths use 2–3 inches of gravel over a prepared base. High-traffic areas may need thicker lifts or a stabilized base to reduce rutting and migration.
Start with 120–160 sq ft/hr per worker on easy access sites. Reduce for stairs, long hauling distances, thick layers, or precise edging. Increase for simple top-ups on flat, open ground.
Waste covers minor spills, uneven subgrades, and the extra material needed to achieve a consistent finished thickness. A 5–10% overage is common for small landscape projects.
No. Productivity controls spreading time. Optional task rates represent separate steps such as base prep, raking, and compaction. Together they produce a more complete crew-time estimate.
Enable equipment when you plan to rent or charge for tools like a plate compactor, powered wheelbarrow, or small loader. Enter an hourly rate and any fixed fee to match your invoice.
If your computed total is below the minimum, the calculator outputs the minimum instead. This is useful for small jobs where setup and travel overhead make a low subtotal unrealistic.
