Built and powered by Brocklesby AI

Who is behind Portfolio Calculator?

Portfolio Calculator is designed, built and maintained by Brocklesby AI, an AI automation studio based in the United Kingdom. Brocklesby AI builds custom software, AI tools and automations, and this site is one of its free public projects.

The goal is simple: give people in the UK the kind of clear, honest financial planning tools that are usually locked behind paywalls, sales funnels or advisers charging by the hour. Every calculator here is free, runs entirely in your browser, and collects no data.

What does Brocklesby AI do?

Brocklesby AI helps businesses put artificial intelligence to practical use. Rather than selling hype, the studio focuses on tangible outcomes: automating repetitive work, building custom internal tools, connecting systems together, and creating software that saves time and money.

Typical work includes:

• AI automation: removing repetitive manual tasks by connecting tools and building intelligent workflows.
• Custom tools and software: bespoke calculators, dashboards and applications built for a specific need, much like this site.
• Practical AI integration: helping organisations adopt AI in a way that actually delivers value rather than adding complexity.

The studio works on a straightforward principle: prove the value first. If a tool or automation does not save real time or money, it is not worth building.

Why build free calculators?

Portfolio Calculator started as a demonstration of what thoughtful, well-built tools can look like. Financial planning is an area full of jargon, hidden agendas and paywalls, so it was a natural fit for a free, transparent set of tools that put the user first.

The same care that goes into these free calculators is what Brocklesby AI brings to its commercial work. If you have seen how clear and useful these tools are, that is the standard the studio builds to.

Our commitment to privacy

Every tool on Portfolio Calculator runs entirely in your browser. There is no backend, no database, no cookies, no analytics and no email capture. Nothing you type into a calculator is ever sent anywhere. This is a deliberate choice, and it reflects how Brocklesby AI thinks about building trustworthy software.
