Marketing Budget Allocation Optimizer

Enter a base ROAS and diminishing-returns exponent for each channel to see the budget split that maximizes total projected return.

The model assumes Revenue = Base ROAS × Spend^Exponent per channel (diminishing returns, 0 < exponent ≤ 1) and uses a greedy algorithm that allocates the budget incrementally to whichever channel has the highest marginal return. This is a planning heuristic, not a guaranteed outcome.
