Why use these calculators?
Built by trade software, for trades
These calculators use the same measurement and pricing engine as QuoteCore+, the quoting and job management platform for trade businesses. Every formula - pitch factors, waste allowances, pack-based pricing - is the same maths professionals use to price real jobs.
Free, private, no signup
All calculator math runs in your browser - nothing is uploaded, tracked, or stored on a server. The AI document scanner (quote generator) sends your uploaded image or text to our server for processing. Use calculators on-site from your phone or at the desk, as often as you like.
