Construction claim calculators

Five calculation engines covering the damages categories that come up most often in construction disputes and property claims. Every one runs in your browser, computes unlimited times for free, shows each intermediate step rather than a single total and cites the industry-standard authority behind the method.

Nothing you type is uploaded. Spreadsheets you import are parsed in the browser and never leave your machine, which matters when the figures belong to a live dispute.

Which one do you need?

Most claims use more than one. A delayed project that also generated extra labour cost and sat unpaid for two years touches three of these; a property loss with a disputed depreciation and an injury on the same site touches two others.

• The project finished late and it cost you money. Start with the delay damages calculator for unabsorbed home office overhead, extended field overhead and labour inefficiency.
• You need the true cost of an hour of labour. The labor burden calculator converts a base wage into a fully burdened rate, which is the figure that belongs in a claim or a change order rather than the wage on the timesheet.
• An insurer has depreciated your repair estimate. The ACV / RCV calculator separates replacement cost from actual cash value, handles multi-trade scopes and lets depreciation fall on materials alone where the state prohibits depreciating labour.
• The money has been owed for a long time. The interest calculator accrues statutory prejudgment and post-judgment interest and nets it against any liquidated damages running the other way.
• Somebody was hurt on the site. The injury damages calculator builds economic loss and applies the comparative negligence rule of the state where the injury happened, which changes the answer more than any other input.

What the free version gives you

All five calculators are free to run as many times as you like. You get the full on-screen breakdown, the live chart, every intermediate sub-total and a one-page PDF summary of your own figures. Paying assembles the same numbers into a live-formula Excel workbook, a formatted Word report and a PDF, each carrying your logo, the methodology and the citation for every method used, the version you hand to a client, a carrier or a court. See pricing.

Every calculator links to a matching document checklist and a sample report and to the 50-state + DC rules reference for the state-specific inputs, statutory interest rates, labour-depreciation restrictions, no-damages-for-delay enforceability and comparative negligence rules, each with its citation and a link to the official source.
