You’ve got a fixed budget. Now comes the harder question:
How should you split it?
Search might drive efficient conversions. Social might scale faster. Video builds reach. Display supports retargeting. Every channel has a case — and internal debates usually follow.
The AMA Paid Media Budget Allocator turns those debates into numbers.
Enter your total budget, choose a scenario, and assign percentages across channels. The calculator projects impressions, clicks, conversions, and CPA using benchmark assumptions so you can compare mixes before money goes live.
It’s built for planning and alignment — not prediction magic. The goal isn’t to promise results. It’s to make tradeoffs visible.
Because budget allocation shouldn’t be based on preference. It should be based on modeled outcomes.

Why Use the Paid Media Budget Allocator
- Compare mixes without guesswork
Swap allocations and immediately see how projected CPA and conversion volume change. - Stress-test expectations
The scenario setting adjusts CPM assumptions so you can model better- or worse-than-baseline conditions. - Turn a budget split into forecasted outcomes
Converts budget into a simple funnel (impressions → clicks → conversions) per channel. - Support clearer planning conversations
Helps teams discuss tradeoffs with numbers instead of channel preferences.
How To Use the Toolkit
- Enter Total Budget ($).
- Select a Scenario: Baseline, Aggressive, or Conservative.
- Set Channel Allocation (%) for Search, Social, Display, and Video.
- Keep the allocation total ≤ 100%.
- Review Projected Results for totals (spend, impressions, clicks, conversions).
- Review each channel’s Spend and CPA.
- Adjust allocations and scenarios until the projection matches your planning target.
Paid Media Budget Allocator Features & Capabilities
| Feature | Description |
|---|---|
| Total Budget | Sets the total spend used for projections. |
| Scenario | Baseline / Aggressive / Conservative (applies a multiplier to CPM assumptions). |
| Channel Allocation | Budget split inputs for Search, Social, Display, and Video. |
| Total ≤ 100% rule | Prevents allocations that exceed 100%. |
| Channel Benchmarks | Uses built-in CPM, CTR, and CVR assumptions per channel. |
| Projected Results | Calculates spend, impressions, clicks, conversions, and CPA per channel. |
| Totals Summary | Aggregates spend, impressions, clicks, and conversions across channels. |
Common Challenges Solved by This Toolkit
| Challenge | Toolkit Solution |
|---|---|
| “We need a starting allocation for a fixed budget.” | Lets you build a split and see projected outcomes immediately. |
| “Channel debates are opinion-based.” | Forces tradeoffs into comparable outputs (conversions and CPA). |
| “We don’t have perfect benchmarks yet.” | Uses documented priors so you can plan, then replace with your own rates later. |
| “We need a quick scenario plan.” | Scenario setting models better/worse cost conditions without rebuilding the sheet. |
| “We want to avoid overcommitting to one channel.” | Makes it easy to test balanced vs concentrated mixes and see what changes. |
Tip
If you have your own CTR/CVR by channel, use this allocator for mix comparisons, then sanity-check the forecast by swapping in your observed rates before finalizing a plan.
