Blog/Paid Media Strategy
How to set a paid media budget — a framework for any business size.
Most businesses set paid media budgets by copying competitors or picking a number that feels comfortable. The right approach: work backwards from a revenue target, calculate the conversions you need, estimate the traffic required to produce them, and price that traffic by channel. Factor in your LTV:CAC ratio to know what you can afford to pay per acquisition. The budget becomes a financial model, not a marketing expense.

“The businesses that scale paid media fastest are the ones who treat it like a financial model, not a marketing cost. If you know your LTV and your CAC ceiling, budget decisions make themselves.”

The backwards model
How to calculate your budget from first principles.
Set your revenue target
Pick a specific, monthly revenue target from paid media. Not a vague goal — a number. $50K, $200K, $1M/month. This becomes the anchor for everything that follows.
Calculate conversions needed
Revenue target ÷ average order value (or average deal size for B2B) = conversions needed. Example: $200K ÷ $400 AOV = 500 orders/month needed.
Estimate traffic required
Conversions needed ÷ expected conversion rate = sessions or clicks needed. Use your current site CVR or industry benchmark (2–3% for eCommerce, 3–6% for lead gen landing pages). Example: 500 orders ÷ 2.5% CVR = 20,000 sessions/month.
Price the traffic
Sessions needed × average CPC for your channel = budget floor. Google Search CPC might be $2–$5, Meta CPM converts to roughly $0.50–$2 per click. Example: 20,000 sessions × $2.50 avg CPC = $50,000/month. Add 20% buffer for learning phase inefficiency.
Sanity-check against LTV:CAC
What is your maximum allowable CAC given LTV? Revenue target ÷ conversions = implied CAC ($200K ÷ 500 = $400). Is $400 CAC sustainable given your LTV? If LTV is $1,200, LTV:CAC = 3:1 — sustainable. If LTV is $600, ratio is 1.5:1 — not sustainable.
Budget by business stage
Testing
$2K–$5K/month
Single channel only. Goal: prove CAC is below ceiling. No scaling until first profitable month. Google Search or Meta — pick one.
Growing
$5K–$20K/month
Primary channel proven. Add secondary channel. Begin audience building and creative testing. Start collecting data for scaling decisions.
Scaling
$20K+/month
Multiple channels running profitably. CBO on Meta, Smart Bidding on Google. Full creative production cycle. 10–20% testing budget ring-fenced.
The 10–20% test budget rule
Reserve 10–20% of your total paid media budget for testing: new creative concepts, new audiences, new placements, and new channels. This testing budget should be ring-fenced from core campaign performance budgets — you are buying learning, not conversions. The insights from testing feed the core campaigns. Brands that don't test systematically run the same campaigns until performance declines, with no backup strategy ready.
Seasonality planning
Q4 (October–December) sees CPMs rise 30–80% across all platforms as every advertiser competes for the same eyeballs. Plan for increased budgets in September/October to build audience pools before costs peak. BFCM (Black Friday/Cyber Monday) requires 3–4× normal daily budget to maintain impression share. Build this into your annual budget model — flat monthly spend across 12 months is the most common planning mistake.
Budget reference by revenue target
| Revenue target | Required conversions | Budget estimate | Channel split |
|---|---|---|---|
| $100K/month | ~200 (at $500 AOV) | $5K–$8K/month | Google Search 60%, Meta 40% |
| $250K/month | ~500 (at $500 AOV) | $12K–$18K/month | Google Search 50%, Meta 35%, TikTok 15% |
| $500K/month | ~1,000 (at $500 AOV) | $25K–$40K/month | Google 45%, Meta 35%, TikTok 20% |
| $1M+/month | ~2,000+ (at $500 AOV) | $50K+/month | Full multi-channel, test new platforms |
Estimates based on eCommerce at $500 AOV, 2–3% CVR. Adjust for your product economics.

FAQ
Common questions about paid media budgets.
How do I calculate the right paid media budget for my business?+
Start with your revenue target. Divide by your average order value (or deal size) to get the number of conversions needed. Divide by your expected conversion rate to get the traffic needed. Multiply traffic by your average CPC or CPM equivalent to get the budget. Example: $500K revenue target ÷ $500 AOV = 1,000 orders needed ÷ 3% conversion rate = 33,333 sessions needed × $1.50 average CPC = $50,000 budget. Build in a 20% buffer for learning phase inefficiency.
What is a good LTV:CAC ratio for paid media?+
A 3:1 LTV:CAC ratio is the minimum sustainable threshold — meaning if your customer is worth $300 lifetime, your acquisition cost should not exceed $100. A 5:1 ratio is healthy and allows for profitable scaling. Above 10:1 suggests you're underspending and leaving growth on the table. Below 3:1 means paid media is either not profitable or the product economics don't support paid acquisition at current conversion rates.
How should I allocate paid media budget across channels?+
For most businesses: allocate 50-60% to your proven primary channel (usually Google Search for lead gen, Meta for eCommerce), 25-30% to your secondary channel, and keep 10-20% for testing new channels, creatives, or audiences. New accounts should concentrate budget on one channel until CAC is proven before diversifying. Spreading $5K/month across 4 channels gives each $1,250 — not enough for any of them to work.
How often should I review and adjust my paid media budget?+
Review budget pacing weekly (are you on track to spend the planned amount?), performance metrics weekly (CPL, ROAS, CPA trends), and full budget reallocation monthly (which channels warrant more investment, which warrant less). Major budget restructuring should happen quarterly, aligned with business planning cycles. Avoid making budget changes more frequently than weekly — each change can reset learning phases.
