Excavation Cost Calculator

Estimate excavation costs with itemized breakdown and editable rates for local pricing.

How It Works

This excavation cost calculator provides a quick estimate with an itemized breakdown you can adjust to match local rates. It combines volume calculation, truckload estimation, and cost line items in a single tool.

Self-Contained Volume Calculation

Enter the excavation dimensions (length, width, depth) and select a soil type. The calculator computes the bank volume and applies the swell factor to get the loose volume, which is used for all cost estimates. No need to calculate volume separately.

Cost Line Items

  • Excavation/Digging: Rate per cubic yard applied to loose volume
  • Hauling: Rate per load applied to number of truckloads
  • Disposal: Rate per cubic yard applied to loose volume
  • Labor: Rate per hour applied to estimated hours
  • Equipment: Rate per hour applied to estimated hours

Inline Rate Editing

All rates use US national averages as defaults. Click any rate in the cost table to edit it with your local pricing. The totals update immediately. This makes the calculator useful for both quick estimates and detailed bidding.

Contingency

The contingency percentage adds a buffer to the subtotal for unexpected costs. Adjust this based on how well-defined your project scope is. Set to 0% for a bare-minimum estimate.
