About us
Smarter property decisions start with better numbers
Breadcrumb Tools is a free utility site providing mortgage and property calculators for homebuyers, investors, and renters across five countries. Every calculator is localized — built with the right terminology, currency, formulas, and defaults for each market.
Our mission
Property is one of the most significant financial decisions most people make. Yet the tools available to help people model, compare, and understand property decisions are often oversimplified, US-centric, or locked behind paywalls.
Breadcrumb Tools exists to change that. We provide free, high-quality property calculators that are genuinely useful — with real formulas, meaningful defaults, worked examples, and clear explanations. No signup required. No data collected. No paywalls.

How our calculators work
All calculations happen in your browser using standard financial formulas. We use the standard annuity formula for mortgage payment calculations, compound interest for savings projections, and industry-standard yield formulas for rental analysis.
Results are estimates — they provide useful benchmarks for planning and comparison, but should not replace advice from a licensed mortgage broker, financial adviser, or property professional. See our full disclaimer for details.
Privacy
We don't store, transmit, or sell your calculator inputs. All calculations happen locally in your browser. We use standard analytics to understand which calculators are most useful, but we do not link analytics data to individual users or calculator inputs. See our privacy policy for full details.
