The Long & Short Marketing Budget Calculator estimates how a marketing budget divides between activity that pays back inside the year and activity that compounds over several years. The model follows Binet and Field's central finding in The Long and the Short of It: brand building and sales activation run on different clocks, so a budget has to be split rather than blended. You enter spend by channel; the calculator applies System1 touchpoint impact weights, in the formula set built by Oliver JP Osborne, and returns an estimated long-to-short ratio. The result is a diagnostic, not a verdict. It shows whether your current mix is over-weighted to activation, and what moving a share of spend from one side to the other would do to the balance. Andrew Tindall's Creative Dividend work informs the creative weighting. The calculator is free, runs in the browser and is built for a budget review rather than a report.

It is the split between brand-building spend, which compounds slowly, and activation spend, which converts now. The calculator balances the two for a given budget.
There is no single number: it depends on category, margin and growth stage. The calculator shows what your chosen split implies rather than prescribing one.
