Our mission
CalcFlow was created to make financial maths accessible, accurate, and genuinely useful. Whether you’re planning a mortgage, teaching compound interest, or comparing loans, we believe the tools you use should be simple, transparent, and trustworthy.
Our calculators are designed to be fast, clear, and reliable — no adverts blocking your view, no confusing jargon. Just correct maths presented cleanly, with the option to explore how each result is calculated.
Who we are
CalcFlow is an independent UK-based project led by educators and developers passionate about financial literacy and computing. The platform grew out of classroom tools built for A-Level and GCSE Computer Science students, evolving into a public suite of calculators for real-world finance.
Every calculator is coded and tested in-house, ensuring precision and accuracy. We also publish open guides and teaching resources alongside each tool, so learners and teachers can see the maths behind the results.
Our values
- Transparency: Clear methods and formulae on every calculator page.
- Accuracy: Tested algorithms, double-checked results.
- Privacy: No tracking cookies or hidden data collection.
- Education-first: Tools designed to teach as well as calculate.
