Marketing budgets: building scenarios that survive a bad quarter
How to set marketing budgets starts with strategy, cost and commitment audits, full-cost estimates, scenarios, portfolio choices, funding gates, and reforecasts.
What to take away
- Anchor to a revenue share, not last year's spend. Common planning ranges run 5% to 12% of expected revenue for B2B services and 10% to 20% for direct sales.
- Split the total into committed costs near 55%, flexible spend near 35% and a reserve near 10%.
- Build three scenarios with real numbers before approval, and draft the cut list for the worst one.
- Set a trigger that moves you into the conservative case automatically, before the quarter ends.
- Reconcile commitments, invoices and outcomes monthly in the file finance already reads.
Size the budget before you shape it
Start with an anchor, then adjust. Take the revenue you expect, apply a share, and test it against costs you have already committed. If commitments eat more than 60% of that number, the budget cannot absorb a bad quarter.
Ranges differ by model. Service businesses with long sales cycles often plan 5% to 12% of revenue. Direct-to-consumer brands often plan 10% to 20%. Treat both as planning ranges, not published benchmarks.
Set the floor from two questions. What work cannot stop without losing customers? What is the smallest amount that keeps a channel learning? Without a finance partner, the SBA marketing and sales guide covers the planning basics.
Before costing anything, write down the revenue target, gross margin, cash available this quarter, the hires you can carry and the three channels you will not run. Marketing budgets: the questions that matter works through the remaining inputs in that order.
Example: a $720,000 budget in three cases
This worked example uses a fictional B2B software firm with $6.0M of expected annual revenue. The arithmetic matters, not the company.
Its marketing budget lands at $720,000, or 12% of revenue. Committed costs take $396,000: two fully loaded salaries, an agency retainer, the tool stack, a research contract and minimum media commitments.
A $720,000 budget in three cases
Conservative
- Revenue plan
- $5.1M
- Marketing budget
- $561K (11%)
- Committed
- $396K
- Flexible
- $115K
- Reserve kept
- $50K
Central
- Revenue plan
- $6.0M
- Marketing budget
- $720K (12%)
- Committed
- $396K
- Flexible
- $252K
- Reserve kept
- $72K
Upside
- Revenue plan
- $6.9M
- Marketing budget
- $828K (12%)
- Committed
- $432K
- Flexible
- $324K
- Reserve kept
- $72K
The conservative case pulls $159,000 out of the central plan. Paid media goes first because it can be paused inside a week. Content production follows, then events. The upside case commits $36,000 more for a third hire.
The Bureau of Labor Statistics publishes wage data for advertising and promotions managers. Use it for the salary line instead of a guess.
Claims carry a cost too. The FTC's advertising and marketing guidance sets out what you must prove, and that review belongs in production budgets.
Where the money goes by channel
Allocate the flexible share, not the whole budget, because committed costs are already fixed. The split below is a typical range for a B2B software firm.
| Channel | Share of flexible spend | Typical range |
|---|---|---|
| Paid search and paid social | 30% | 20% to 40% |
| Content, SEO and lifecycle email | 20% | 15% to 25% |
| Events and field | 20% | 10% to 25% |
| Partners and affiliates | 10% | 5% to 15% |
| Brand and PR | 10% | 5% to 15% |
| Tests | 10% | 5% to 10% |
Cap any single channel at 40% of flexible spend. Above that, one algorithm change or one cancelled conference takes the quarter with it.
Keep blended CAC payback under 12 months for B2B and under 6 months for self-serve. A channel still past 18 months is a brand bet, so fund it from the brand share.
Outside ranges help you check the anchor. Marketing planning benchmarks: the numbers and what sits behind them shows what other teams report and how wide the spread runs.
Reserve, triggers and the cut list
- Set the reserve at 8% to 12% of the budget. Below 8% it cannot cover a slipped campaign; above 12% it tends to get spent.
- Write the cut list before approvaleach line, its notice period, its place in the order.
- Pick a trigger. Two months below 85% of the revenue plan, or pipeline coverage under 3x, moves you to the conservative case.
- Release flexible money in tranches of 25%. Hold the next tranche until the current one hits its CAC target.
- Review the reserve quarterly. Money untouched for four quarters was never needed.
Before signing, confirm the plan carries:
- Committed costs with end dates and notice periods.
- One named owner per line, not a department.
- The same line structure across all three scenarios.
- A written cut list and a written trigger.
Tie each release to a target written before the money, and marketing goals and objectives explains how to keep the two in step.
Reconcile with finance every month
Keep one master file in Excel or Google Sheets. Pull actuals from QuickBooks, Xero, NetSuite or Sage Intacct, media spend from Google Ads and Meta Ads Manager, and outcomes from GA4. Publish it in Looker Studio.
Sort every variance into one of five buckets: volume, rate, timing, mix, scope. Timing variance reverses on its own. The other four need a decision.
A scenario is not a forecast with three columns. It is a pre-agreed decision: if this happens, we do that.
