What It Does

Use the calculator with intent

The Marketing Budget Allocator takes a total budget and a list of channels, each with an allocation percentage and optional expected ROAS. It converts percentages to dollar amounts, multiplies by ROAS to project revenue, and computes a blended ROAS across all channels. Allocation percentages must sum to 100%.

Marketing managers, founders wearing the marketing hat, and agency strategists who need to plan how to split a fixed budget across paid search, social, content, email, and other channels while projecting overall return.

Interpreting Results

Blended ROAS is the most important output. If it is below 1.0, your overall marketing spend is unprofitable. Per-channel amounts show exactly where each dollar goes, making it easy to identify underperforming channels.

Input Steps

Field by field

  1. 1

    Total Budget

    Enter your total marketing budget for the period in dollars. This is the total amount available to allocate across all channels.

  2. 2

    Channels

    Add each marketing channel with a name, allocation percentage, and expected ROAS. Percentages must sum to exactly 100%. If you do not know ROAS for a channel, leave it blank.

  3. 3

    Results

    Review per-channel dollar amounts, expected revenue, and the blended ROAS. Shift allocation toward higher-ROAS channels unless you are intentionally investing in brand or awareness.
