1. Accuracy and mathematical integrity

Every calculator and tool on FinToolSuite is powered by our promise of Engineering Accuracy. Here’s how we put that commitment into action:

  • Formula derivation: We use established financial accounting principles, such as Amortisation (gradual repayment of a loan over time), CAGR (Compound Annual Growth Rate, representing the mean annual growth rate of an investment over a specified period), and Ratio Analysis (evaluation of various financial metrics to assess a company’s performance), derived from authoritative sources, such as the Office for National Statistics (ONS) and the Financial Conduct Authority (FCA).
  • Edge-case testing: We push every tool to its limits, testing wild scenarios like hyperinflation, zero income, or negative interest rates to guarantee they hold up under pressure.
  • Human oversight: Before any tool goes live, our lead developers roll up their sleeves for a hands-on audit, ensuring every algorithm meets our high standards.

2. Transparency and AI disclosure

In today’s automated world, we put transparency front and centre as our core value.

  • We sometimes use AI (like language models) to draft texts or sort data.
  • Nothing is published without a human review. AI Insights are marked and checked by our editors.

3. Update and review frequency

The financial world is dynamic. We maintain a Rolling Review Cycle:

  • Main tools (such as Mortgage and Tax) are checked every 90 days to ensure they use the latest data.
  • We check older tools once a year to ensure they run fast and work with all browsers.

4. Independence and objectivity

Here, numbers, not commissions, lead the way to your results.

  • No third-party ads or partners affect our tool results.
  • We never add features for money. Any tips or links are provided only if they are helpful in the tool.

5. Data privacy and user empowerment

Consistent with our Privacy-First approach:

  • Your calculations run in your browser and use Local Storage. We do not save your financial info.
  • Portability: We provide tools for users to export their data (including PDF and JSON, a lightweight data-interchange format), ensuring they retain ownership of their financial modelling.

Capital at Risk: The value of investments can go down as well as up.
