This tool is provided "as is" for estimation purposes only.
HexBolt is a free calculator to help contractors build bid estimates. It does not constitute legal, financial, tax, or accounting advice. The developer accepts no liability for under-bidding, financial loss, tax errors, or any damages resulting from its use.
Sales Tax / VAT: All bids are exclusive of applicable sales tax, VAT, or GST unless you manually enter a rate above. Consult your accountant for your local rate.
Markup vs. Gross Margin: The default profit mode is "Markup" (cost × (1 + %)). Toggle to "Gross Margin" for pricing where profit is a % of the final sale price. These produce different final prices — know which method your business uses.
Contingency: This tool applies contingency to (Direct Cost + Overhead) combined — a conservative compounding approach. Some contractors apply it to Direct Cost only; your result may differ slightly from other tools.
Privacy: This tool runs 100% in your browser. No data is sent to any server. Shareable links encode inputs as URL parameters — do not share links containing sensitive client information over unsecured channels.
