We build free, professional-grade real estate calculators that help everyday buyers, investors, and renters make confident, data-driven decisions.
Property is one of the biggest financial decisions most people ever make. Yet the tools available to help people navigate that decision are often locked behind paywalls or simply out of date. We set out to fix that.
Every calculator uses the same financial logic a professional would use — with up-to-date 2026 tax bands and real mortgage logic. All completely free.
All calculations happen directly in your browser. The numbers you enter never leave your device. No account, no data stored, no emails.
Unlike most tools that focus on one market, DealzMaster covers USA and UK — from SDLT and buy-to-let yields to closing costs and FHA mortgages.
Every tool is paired with guides that explain what the results mean — so you're not just getting a number, you're learning how to use it.
DealzMaster Tools is operated by BLUEORBYT LTD and provides calculators for informational purposes only. Nothing on this website constitutes financial, investment, mortgage, tax, or legal advice. Always consult a qualified professional before making any property decision.
