What a BOQ calculation looks like

Each BOQ line prices one scope item by multiplying the quantity by its unit rate:

Line Total = Quantity × Unit Rate

The grand total is the sum of every line total, which becomes the base for your quotation before adding markup, VAT, or contingency.

Worked example

120 m³ of excavation at $8/m³ = $960. 45 m³ of foundation concrete at $95/m³ = $4,275. 300 m² of blockwork at $14/m² = $4,200. Grand total: $9,435.

Frequently asked questions

What comes after the BOQ total?

The BOQ total is your direct cost base. Most contractors then add overhead, contingency, and a markup for profit before issuing the figure as a quotation to the client — see our Project Cost Calculator and Markup Calculator.

What units are typically used in a BOQ?

Units follow the trade: m³ for concrete and excavation, m² for flooring/blockwork/plaster, linear meters (m) for piping or skirting, and each (no.) for fixtures, doors, or fittings.

Can I reuse this for a real project?

This tool is for quick estimates. For a full project — hundreds of line items, revisions, actual-vs-budget tracking, and PDF export — use Metrak’s BOQ module inside a real project.
