Split a paid social budget by goal and audience, not by habit. Published 2026 CPM ranges run about $4 to $12 on Reddit, $6 to $12 on TikTok, $8 to $17 on Meta and $25 to $40 on LinkedIn. Cheaper impressions are not always cheaper customers, so set the split from cost per qualified outcome and test before you commit.

How much does each platform cost?
CPM, the price per 1,000 impressions, differs sharply by platform. Ranges below come from 2026 benchmark roundups and vary by industry, audience and season.
| Platform | Typical 2026 CPM | Best at | Watch for |
|---|---|---|---|
| About $4 to $12 | Niche communities, B2B and high-intent topics | Smaller scale, creative must fit the community | |
| TikTok | About $6 to $12 for In-Feed | Reach and discovery with younger audiences | Creative fatigue, low conversion on cold traffic |
| Meta (Facebook and Instagram) | About $8 to $17 | Broad reach and direct response | Rising costs in peak weeks |
| About $25 to $40 | B2B targeting by role and company | High cost per click and per lead |
Metricool's 2026 Social Ads Report, which covers 628,969 campaigns and $471 million in spend on Meta and TikTok, found TikTok CPMs about 22% below Meta's, with both rising year over year (Meta up 8%, TikTok up 5.5%). Peak weeks cost more. One roundup recorded Black Friday CPM spikes of up to 138%.
Why is a low CPM not the same as a low cost per customer?
A cheap impression only helps if it turns into an outcome at a similar rate. One 2026 analysis worked through an example where a $6 TikTok CPM produced a $75 customer acquisition cost, while a $10 Meta CPM produced $50. Conversion rates, audience intent and creative all change the result.
LinkedIn is the clearest case. Its CPM is roughly three to five times Meta's, but a B2B team may still get a better cost per qualified lead there than on cheaper platforms. Compare platforms on cost per qualified outcome, not on CPM.
How should you set the split?
Set the split in five steps, working from the goal backward.
- Define the outcome. Sales, qualified leads, app installs or awareness each favor different platforms.
- Map the audience. Where does the buyer spend time, and can the platform target them precisely?
- Set a testing reserve. Hold back 10% to 20% of the budget for new platforms, audiences and creative.
- Fund proven channels first. Put most of the budget where cost per outcome is already known.
- Review weekly, rebalance monthly. Let the data move budget, but avoid reacting to single-day swings.
These steps match the approach in the paid media budget guide, which also covers how paid social sits next to search and AI visibility spend.
What does an illustrative split look like?
The splits below are planning starting points, not benchmarks. Real mixes depend on category, margin and creative. Treat them as hypotheses to test.
| Brand type | Meta | TikTok | Testing reserve | ||
|---|---|---|---|---|---|
| Consumer ecommerce | 50% | 25% | 0% | 5% | 20% |
| B2B software | 25% | 0% | 45% | 15% | 15% |
| Beauty and lifestyle | 40% | 35% | 0% | 5% | 20% |
| Local services | 70% | 10% | 0% | 5% | 15% |
Two notes on reading the table. First, a zero for LinkedIn on a consumer brand reflects cost, not a ban, and a brand with a B2B arm should revisit it. Second, TikTok works best when it is paired with creator content. 5W's TikTok marketing practice builds the creative and the paid support together.
What creative does each platform need?
Budget splits fail when the same asset is pushed to every platform. Each feed rewards a different style, and creative production is a real cost to plan for.
- TikTok: Native-feeling vertical video that looks like it belongs in the feed. Creator-led content usually outperforms polished studio spots.
- Meta: A mix of short video, carousels and static images, tested against each other. Strong hooks in the first seconds matter on Reels and Stories.
- LinkedIn: Clear, professional creative that leads with a business problem, a data point or a customer result. Document and thought-leadership formats work for B2B.
- Reddit: Plain, honest creative that respects the community. Overly slick ads tend to draw negative comments, so tone and subreddit fit matter.
Plan creative volume before you set the budget. A platform with a thin creative pipeline wears out faster, and refresh needs rise with spend. As a rule of thumb, reserve part of the paid social budget, or a separate creative budget, for new assets every month instead of treating creative as a one-time cost.
How do you test and rebalance?
Run structured tests, not constant tweaks.
- Test one variable at a time: audience, creative or offer.
- Give each test enough spend to learn. Cutting tests off after a few days produces noise.
- Track the full funnel: impressions, cost per qualified visit, cost per lead or sale and downstream revenue.
- Use incrementality checks where budget allows, such as geo holdouts or conversion lift tests, to confirm that paid social caused the result.
- Refresh creative on a schedule. Fatigue shows up first on TikTok and Meta.
Judge results on cost per qualified outcome and incremental revenue. Clicks alone can mislead, because a platform with cheap clicks can still produce few customers.
A simple weekly review checklist
- Compare cost per qualified outcome by platform.
- Flag any ad set with rising frequency and falling results.
- Move 5% to 10% of budget toward the best performer, no more.
- Log what changed so results can be explained later.
What mistakes waste paid social budget?
Four mistakes show up again and again. The first is copying a competitor's split without knowing their margins or goals. The second is judging platforms on CPM or click cost instead of cost per qualified outcome. The third is spreading a small budget across too many platforms, which leaves every test too thin to read. The fourth is letting creative go stale, so costs creep up while results fall.
A simple guard against all four is to write down the goal, the outcome metric and the review date before launch. When a platform misses its target for a full test window, move its budget to the best performer instead of waiting for it to recover. Revisit the split each quarter, because platform costs, audience behavior and your own priorities all change.
Where does paid social fit in the full budget?
Paid social is one lane in a larger mix with search, programmatic, connected TV, retail media and earned media. Its job is usually reach, discovery and retargeting, while search captures existing demand. Budget for the whole mix first, then divide social spend.
5W plans paid social as part of a full program with PR, creative and AI Visibility, all done in house. Paid media and performance marketing retainers run $15,000 to $25,000 per month for most accounts, separate from ad spend. See the performance marketing practice for how 5W approaches channel mix, and the paid media management cost guide for fees.
What are the key takeaways on paid social budgets?
- CPMs run about $4 to $12 on Reddit, $6 to $12 on TikTok, $8 to $17 on Meta and $25 to $40 on LinkedIn.
- A low CPM does not mean a low cost per customer, so compare cost per qualified outcome.
- Hold 10% to 20% of the budget for tests and rebalance monthly.
- Plan creative for each platform and refresh it on a schedule.
Frequently asked questions
How much should I spend on paid social?
Set the total from your revenue goal and cost per outcome, then split it by platform. Hold 10% to 20% for testing.
Which platform is cheapest for paid social?
Reddit and TikTok usually have the lowest CPMs, and LinkedIn the highest. Cheapest is not best, because outcomes per impression differ.
Is TikTok cheaper than Meta?
On average, yes. Metricool's 2026 data found TikTok CPMs about 22% below Meta's. Conversion rates and creative needs can offset the saving.
Is LinkedIn worth the cost?
For B2B campaigns that need role and company targeting, often yes. Judge it on cost per qualified lead, not CPM.
Should small brands use every platform?
No. Start with one or two where the audience is, learn, then expand. Spreading a small budget thinly makes tests inconclusive.
How often should I change my paid social split?
Review weekly and rebalance monthly. Avoid reacting to single-day swings.
