Base & Aggregates Calculators & Estimators
Gravel, stone, sand and sub-base quantities for the layers under every pavement. Built for homeowners planning a project and contractors preparing a bid: enter dimensions, get the quantities and budget ranges suppliers actually quote in.
Gravel Calculator
Gravel tonnage and cost by area and depth, with densities for loose, crushed, pea and river rock.
Aggregate Calculator
General construction aggregate tonnage with adjustable density for any graded material.
Crushed Stone Calculator
Crushed stone and crusher run tonnage for bases, pads and driveways.
Sand Calculator
Sand tonnage and 50 lb bag count for bedding, masonry and fill applications.
Sub-base Calculator
Granular sub-base (GSB) tonnage for the layer between subgrade and base course.
Fill Dirt Calculator
Cubic yards and tons of fill dirt for grading, holes and elevation changes.
Limestone Calculator
Crushed limestone tonnage for bases, driveways and ag-lime applications.
Rip Rap Calculator
Rip rap stone tonnage for erosion control on slopes, channels and shorelines.
Decomposed Granite Calculator
DG tonnage for pathways, patios and xeriscape surfacing.
When to use which calculator
For anything measured in tons of stone, the Gravel Calculator is the general tool — it has density presets for the common materials. Reach for the specific calculators when the material matters: Crushed Stone for compacted bases, Sand for bedding, Sub-base for the engineered layer under pavement, Rip Rap for erosion control. Ordering by the cubic yard instead of the ton (soil products) is the Fill Dirt Calculator's job.
