About CoryVu

CoryVu is an independently run collection of practical calculators and tools.

Our aim is to help you understand the numbers behind everyday decisions. Each tool combines useful results with explanations, assumptions and practical next steps.

How the tools are checked

CoryVu uses automated software tests, selected worked examples and browser checks to help identify errors and keep tools usable on mobile and desktop.

Where a tool relies on published rules or guidance, we provide relevant sources so you can check the underlying information.

Read how we check our tools.

Understanding the limitations

Results depend on the information you enter and the assumptions explained on each page. Changing rules, individual circumstances and provider-specific terms may affect the outcome.

Tools covering financial, employment, legal or safety topics provide general information and estimates. They do not replace advice tailored to your circumstances.

Help improve CoryVu

If you find an unexpected result, outdated information or an unclear explanation, please use the tool’s feedback option or contact us.
