How to use it

Enter your total marketing budget, then add each channel with a name, an allocation percentage, and optionally its expected ROAS (return on ad spend). The allocation percentages must sum to exactly 100%, which forces the real trade-off: every dollar you give one channel is a dollar taken from another, rather than a wishlist where everything gets funded.
Read the per-channel breakdown showing each channel's budget amount and its expected revenue (budget times ROAS) where you supplied one, plus the total allocated and the blended ROAS across channels. The blended ROAS is the headline number, because it tells you the overall return your mix is expected to produce, weighting each channel by how much budget it actually receives.
Use expected revenue per channel to expose where the budget is working hardest. A channel with a high allocation but a low ROAS is dragging your blended return down, and shifting even a few percentage points toward a higher-ROAS channel can lift total expected revenue without spending an extra dollar. The allocation that maximises blended ROAS is rarely the one that feels intuitive.
Treat ROAS estimates as hypotheses to test, not facts, especially for channels you have not run before. Model a conservative case where your two highest-ROAS channels come in 30% below expectation, since over-allocating to an unproven channel on an optimistic estimate is the most common way a budget underperforms. Reserve a portion for testing rather than committing the whole budget to current bets.
Re-run monthly as real ROAS data replaces estimates, and rebalance toward what is actually working rather than what you planned. Pair the per-channel output with the social media ROI and landing page conversion tools to validate the ROAS assumptions for each channel before you trust the blended number that drives the allocation.
