Last October, a business owner asked me: "I want to do $500k in revenue this Q4. How much should I spend on marketing and where should it go?"
I could have given her a generic answer: "Spend 15-20% on marketing, split it 50/30/20 across Google/Meta/other."
But that would have been useless. Her business wasn't average. She had exceptional Google Ads performance (5.8x ROAS) but weak Meta results (2.1x). She had three months of runway before needing profitability. She was in a hyper-competitive category where BFCM drives 60% of Q4 revenue.
Generic advice would have left thousands of dollars on the table—or worse, burned budget on the wrong channels.
What she needed (and what you need) is a calculator that asks the right questions about your specific business, applies proven allocation frameworks, and outputs a customized budget plan you can actually execute.
That's what this tool does. Answer five questions, get your complete Q4 marketing budget with channel splits, pacing calendar, and ROAS targets.
Answer five questions to get your personalized Q4 marketing budget with channel allocations, ROAS targets, and weekly pacing calendar.
The calculator uses a revenue-first approach combined with historical performance data to recommend optimal marketing spend levels and channel allocations that maximize your probability of hitting revenue targets while maintaining profitability.
Most budget calculators ask "How much do you want to spend?" That's backwards. The right question is "What revenue do you need?" because marketing spend is a means to an end, not the objective itself.
The calculator starts with your Q4 revenue goal, then works backward using industry benchmarks and your specific performance data to determine:
1. Q4 Revenue Goal
This is your target total revenue for October 1 - December 31. Be realistic but ambitious. Most businesses see 30-45% of annual revenue in Q4 if they're consumer-focused.
The calculator uses this to determine minimum required ad spend at your target ROAS.
2. Historical Best Channel Performance
Which advertising channel has delivered your highest ROAS in the past 3-6 months? This becomes your "anchor channel" that receives the highest budget allocation (35-45%).
If you don't have historical data, the calculator uses industry benchmarks based on your business type.
3. Average Order Value (AOV)
Your typical order size affects allowable customer acquisition cost (CAC) and therefore realistic ROAS targets. Higher AOV businesses can sustain lower ROAS because lifetime value is higher.
The calculator adjusts ROAS targets and budget recommendations based on AOV ranges.
4. Gross Margin
After cost of goods sold (COGS), what percentage of revenue is gross profit? This determines your breakeven ROAS and informs how aggressive your budget can be.
At 50% margin, your breakeven ROAS is roughly 2.0x. At 30% margin, it's closer to 3.3x. The calculator factors this into recommendations.
5. Risk Tolerance
Are you in growth mode (willing to accept lower margins for volume) or profitability mode (need strong margins immediately)? This adjusts channel mix and recommended ROAS targets.
Here's what happens when you click "Calculate":
Step 1: Calculate Required Marketing Spend
Formula: Revenue Goal ÷ Target Blended ROAS = Required Ad Spend
Target blended ROAS is determined by your margin and risk tolerance. Conservative businesses target 3.5-4.5x. Aggressive growth businesses target 2.5-3.5x.
Example: $300,000 revenue goal ÷ 3.0x target ROAS = $100,000 marketing budget
Step 2: Allocate Across Channels
The calculator uses a tiered allocation framework based on your historical best performer:
If you indicated Google Ads is your best performer, it gets anchor allocation. Meta becomes secondary. TikTok or display become testing.
Step 3: Set Channel-Specific ROAS Targets
Each channel gets a different ROAS target based on typical performance patterns:
These targets are adjusted based on your margin—higher margin businesses can accept lower ROAS.
Step 4: Build Pacing Calendar
Total budget is distributed across time periods using proven holiday patterns:
Each channel gets week-by-week allocations that account for its optimal pacing pattern.
The calculator includes guardrails to prevent unrealistic plans:
For the complete methodology behind optimal budget allocation, see our detailed holiday marketing budget template guide.
The calculator outputs four key sections. Here's how to read and use each one.
This is your recommended total Q4 marketing spend to hit your revenue goal at your target ROAS.
What to check:
If the budget seems too high: Either lower your revenue goal or accept that you'll need higher ROAS to hit the target with less spend. The calculator shows this trade-off.
If the budget seems too low: You may be in a position to increase revenue goals. Consider whether you have fulfillment capacity and inventory to support higher volume.
This shows how your total budget divides across advertising channels with dollar amounts and percentages.
What to check:
Customizing allocations: The calculator provides a starting point. Adjust based on:
These are the return-on-ad-spend targets each channel needs to hit for your plan to work.
What to check:
If targets seem unrealistic: Either reduce budget (accepting lower revenue) or focus on fewer channels where you're confident in performance.
This shows week-by-week recommended spending across October-December.
What to check:
The pacing calendar is your operational guide—set daily budgets in ad platforms that align with these weekly targets.

Understanding why the calculator recommends certain channel splits helps you make informed adjustments.
When it gets 40-50% allocation:
Why this makes sense: Google Ads (Search + Shopping) captures high-intent demand. People searching "buy X" are ready to purchase. During Q4, search volume increases 40-60% but intent quality remains high. This makes Google the safest bet for reliable conversions.
When to adjust down: If your brand is unknown and you rely heavily on branded search that won't scale, reduce Google allocation. Or if CPCs in your category are prohibitively expensive (over $5-8), you may not be able to profitably scale.
When it gets 30-40% allocation:
Why this makes sense: Meta (Facebook + Instagram) excels at prospecting new customers and retargeting warm audiences at scale. Advantage+ Shopping campaigns can drive massive volume when fed good creative. Meta is essential for businesses that need to acquire new customers during Q4.
When to adjust down: If you have limited creative production, reduce Meta allocation. The platform is creative-hungry—running 5 ads all quarter won't work. Also reduce if your retargeting audiences are small (under 10k warm visitors/month).
When it gets 15-25% allocation:
Why this makes sense: TikTok can deliver exceptional ROAS (3-5x) when you nail creative. It's particularly strong for products under $75 that have viral potential. The platform is less saturated than Meta during Q4, offering better CPMs for businesses that can produce authentic, native-feeling content.
When to adjust down (or to zero): If you can't produce 8-10 short-form videos per month, skip TikTok. Also skip if your product is over $150, targets over-40 demographic, or requires lengthy explanation. Put that budget into proven channels.
When it gets 8-15% allocation:
Why this makes sense: Email and SMS are your highest-ROAS channels (typically 6-12x) because you're marketing to owned audiences. Even modest investment in email ($2,000-5,000 for ESP costs, creative, and list growth) delivers outsized returns during Q4.
When to adjust up: If you have a substantial list (25,000+ subscribers) and strong email infrastructure, increase allocation to 15-20%. Email should be your profit engine.
When it gets 5-10% allocation (or zero):
Why this makes sense (or doesn't): Display retargeting and CTV are brand awareness plays that indirectly boost other channels. They're appropriate for businesses with budgets over $50k who can afford lower-ROAS brand spend. For businesses under $50k total budget, display/CTV allocation should be zero—put those dollars into direct response channels.
When to force to zero: If you need every dollar to show immediate ROAS, eliminate display and CTV. They're nice-to-haves, not essentials.

Get Campaign Templates – $15Channel allocation is half the equation. Timing is the other half. Here's how the calculator determines your pacing strategy.
Phase 1: October Foundation (30-35% of budget)
Purpose: Build retargeting audiences, test creative, establish baseline performance before chaos hits.
Pacing pattern: Week 1 of October starts at 70-80% of your planned BFCM daily budget. This gives platforms time to learn without burning money. By week 4, you're at 90-100% of BFCM daily budget.
Why it matters: Businesses that skimp on October (trying to "save budget for BFCM") consistently underperform in November. You need warm audiences and proven creative before the conversion surge.
Phase 2: BFCM Week Surge (45-50% of budget)
Dates in 2025: November 24 (Monday before Thanksgiving) through December 1 (Cyber Monday).
Purpose: Capture maximum conversion volume during peak intent days.
Pacing pattern:
Cyber Monday typically outperforms Black Friday by 20-30% for online retailers, hence the heavier allocation.
Phase 3: Late December Cleanup (15-20% of budget)
Dates: December 2 through your last shipping cutoff (typically Dec 18-20).
Purpose: Capture last-minute shoppers, gift card buyers, and clear excess inventory.
Pacing pattern: Week 1 (Dec 2-8) at 100% of October daily budget. Week 2 (Dec 9-15) at 120% of October budget (urgency increases). Week 3 (Dec 16-23) at 150% of October budget (final push before shipping cutoffs).
After last ship date, shift remaining budget to gift cards or pause if you don't sell digital products.
Not every channel follows the same pacing. The calculator applies these adjustments:
Google Ads: Front-loads slightly more into October (35% vs. 30% overall) because Search needs less "learning" time than social platforms. Surges heavily during BFCM (50%) to capture peak search volume.
Meta: Follows standard pacing (30% October, 50% BFCM, 20% late Dec) but emphasizes consistency. Dramatic budget swings hurt Meta's algorithm—better to ramp gradually than jump 10x overnight.
TikTok: Front-loads heavily into October (40% vs. 30%) for extensive creative testing. Reduces during BFCM (35% vs. 50%) because creative fatigue typically sets in by late November. Better to find winners early and ride them moderately than burn budget on fatigued creative during BFCM.
Email/SMS: Fairly consistent through Q4 (30/35/35) because list capacity doesn't fluctuate like ad inventory costs. Slight increase during BFCM for daily sends, but not a dramatic surge.
The calculator's pacing assumes you have full budget available October 1. If cash flow is constrained:
Option A: Shift to 25/55/20 split (reduce October, increase BFCM). This is suboptimal but workable if you can't front-load spending.
Option B: Reduce total budget and maintain optimal pacing. Better to do $60k well-paced than $80k poorly paced.
Option C: Arrange credit or financing to bridge the gap. If you're confident in your ROAS, short-term financing to fund October spend pays off in November revenue.
For detailed cash flow and budget tracking, see our Google Sheets budget template.
The calculator gives you a plan, but reality may diverge. Here's when and how to adjust.
If ROAS is 20%+ better than expected:
You've found efficiency the calculator didn't expect. Options:
If ROAS is 20%+ worse than expected:
Cut allocation by 25-30% and reallocate to best performers. Don't give underperformers "one more week" hoping they improve—they rarely do during compressed Q4 windows.
If Black Friday underperforms: Don't panic and overspend on Cyber Monday. Analyze why Friday was weak (site issues? offer not competitive? creative fatigue?). Fix root cause, then execute Cyber Monday as planned.
If Black Friday overperforms: Consider increasing Cyber Monday budget by 20-30% since momentum suggests strong demand. Ensure inventory can support the volume.
If you're approaching stockout on key products:
If you have excess inventory after BFCM:
Deploy your reserve budget to aggressive clearance campaigns in weeks 2-3 of December. Better to move inventory at 40% off than carry it into 2026.
If CPMs or CPCs spike 50%+ above calculator assumptions:
Your options:
Don't panic-pause everything. Make measured adjustments based on whether absolute profit is acceptable even if ROAS is lower.
Every Sunday during Q4, review actual vs. plan:
Make small adjustments weekly (10-20% budget shifts) rather than waiting for major problems. Compounding small corrections prevents big disasters.
The calculator gives you numbers—total budget, channel splits, ROAS targets, weekly pacing. But numbers alone don't run campaigns. You still need execution discipline.
Here's what to do immediately after using the calculator:
Step 1: Take your recommended budget to whoever controls finances (yourself, a partner, a CFO) and get formal approval. "The calculator suggested $75k" means nothing without commitment.
Step 2: Set up your budget tracking system (spreadsheet, dashboard, or tool) with the channel allocations and weekly targets from the calculator. This becomes your single source of truth.
Step 3: Configure daily budgets in each ad platform that align with your weekly pacing targets. Set up budget alerts so platforms don't overspend.
Step 4: Create a weekly review calendar. Every Sunday in October-December, review actual vs. plan and make small corrections.
Step 5: Build contingency plans for the three most likely scenarios: (a) top channel underperforms, (b) BFCM surge is weaker than expected, (c) you hit revenue target early and need to decide whether to keep spending or bank the wins.
The calculator does the math. You still have to do the work. But at least now you're working from a data-driven plan instead of guessing where to spend and hoping it works out.
That's the difference between businesses that hit their Q4 targets and businesses that wonder in January where all the money went.
