2:3
A ratio compares quantities. A ratio of 2:3 means for every 2 parts of one thing, there are 3 parts of another.
A ratio compares parts to each other. A fraction or percentage usually compares one part to the total.
Ratios are used in recipes, maps, scale drawings, sharing money, mixing paint, and comparing rates.
This calculator is designed to help you understand the likely number before you make a decision or start an application.
Your result should be checked against official UK guidance, especially if your circumstances include dependants, exemptions, prior leave, or a complex immigration history.
Treat the figure as a planning tool rather than legal advice. Where the answer affects an application deadline or major payment, speak to an authorised adviser.
