How to use the campaign budget splitter.

Add the requested inputs

Use the labelled fields in the workspace above. If example values are provided, try them first or replace them with your own.

Calculate and review

Use the main action when needed. Minimums are assigned first; the balance follows relative weights, with largest-remainder rounding so every currency unit is allocated.

Try a worked example

Reserve minimums for search and creative, then distribute the remaining £10,000 across channels in proportion to their weights.

Check the assumptions

Weights express your plan, not expected performance. Reallocate from measured marginal results, constraints and experiment design over time.
