Social media reporting drowns you in metrics. Most of them don't tell you whether the campaign is working. Here are the four that do, and the formulas we use in the calculator above.
ROAS (Return on Ad Spend) is the simplest performance metric and the one Meta, TikTok and LinkedIn all report on natively. It's revenue divided by ad spend.
ROAS = Revenue ÷ Ad spendIf you spent £1,500 on Meta ads and generated £4,500 in tracked revenue, your ROAS is 3x. That's the number your media buyer will put in the Monday morning report. It's a good starting point but it's incomplete, it doesn't account for your profit margin, your agency fees, or the cost of making the ad in the first place.
ROI (Return on Investment) is what your finance team actually cares about. It's your profit after every cost, as a percentage of everything you spent to get it.
ROI = ((Revenue − Total Cost) ÷ Total Cost) × 100The same £1,500 ad spend with £4,500 revenue looks very different once you include £650 agency fee, £300 creative production, and 60% cost-of-goods. Your ROI isn't 200%, it's closer to break-even. The ROI calculator above handles this for you automatically once you enter your profit margin.
CPC, CPM, CPA, the diagnostic trio
CPC (Cost per Click) tells you whether your ad is cheap to get people through to your site. CPM (Cost per 1,000 impressions) tells you whether your audience targeting is efficient. CPA (Cost per Acquisition) tells you whether those clicks are actually turning into customers.
When ROAS drops, these three metrics diagnose where. A high CPM with a low CTR means your targeting is wrong. A low CPC with a high CPA means your landing page is leaking traffic. A high CPA means the product-market fit or the offer needs work. Each metric isolates a different part of the funnel.
What good looks like on UK paid social in 2026
Paid social costs rose 8–12% year-on-year in 2025 as more brands piled into Meta and TikTok, but the UK market still runs at roughly 15% lower CPMs than the US. Here's what you should actually expect to pay on each platform, in £ sterling.
By platform
CPM is the single best platform comparison metric, it tells you the raw cost of reaching 1,000 UK eyeballs, regardless of what they do next. TikTok remains the cheapest for impression volume, LinkedIn the most expensive by a wide margin for B2B targeting.
| Platform | UK CPM | UK CPC | Typical ROAS | Best for |
|---|---|---|---|---|
| TikTok | £4–£8 | £0.30–£1.20 | 1.5–2.5x | Reach, younger audiences, virality |
| Meta (Facebook + Instagram) | £8–£14 | £0.50–£2.00 | 2.5–4x | D2C e-commerce, lifestyle brands |
| £2–£8 | £0.15–£1.00 | 2.5–4x | Fashion, home, wedding, food | |
| YouTube | £10–£18 | £0.50–£1.50 | 1.5–3x | Brand awareness, long-form |
| £20–£45 | £4–£10 | Pipeline metric | B2B lead generation only |
By industry
Within each platform, industries compete for the same audiences, so high-demand verticals pay a premium. Beauty and finance pay the most on Meta; apparel and food pay the least. When evaluating your own numbers, the platform benchmark alone isn't enough, your industry benchmark matters more.
| Industry | Meta CPM (UK) | Conversion rate | Target ROAS |
|---|---|---|---|
| Beauty & Skincare | £10–£14 | 2.5–3.5% | 3–4x |
| Fashion & Clothing | £6–£10 | 1.5–2.5% | 2.5–4x |
| Food & Drink | £5–£8 | 3–4.5% | 3–5x |
| Hospitality | £7–£11 | 1.5–2.5% | 2–3x |
| Fitness & Wellness | £8–£12 | 2–3% | 2.5–3.5x |
| Tech / SaaS | £9–£14 | 0.9–1.5% | CPL-focused |
| Finance / Insurance | £12–£18 | 1.5–2% | CPL-focused |
| Education / Courses | £7–£11 | 2–3% | 2–3x |
Six fixes that actually move ROAS for UK brands
We see the same five or six patterns in every paid social audit. Before you cut budget or switch agencies, work through these, most problems are diagnosable in an afternoon.
Refresh creative every 2–3 weeks
Creative fatigue is the silent ROAS killer. Meta's own 2025 data shows the average ad's ROAS drops 30% after week three. Build a library of 8–12 concepts and rotate two at a time.
Use Advantage+ on Meta
Meta's Advantage+ Shopping campaigns outperform manual setups by 15–25% on ROAS on average, and by up to 44% on cost per result. If you're still using traditional campaign setups in 2026, this is your fastest win.
Fix your pixel & server-side tracking
iOS 17+ updates and browser-level ad blockers have broken client-side attribution. If you haven't implemented Conversions API (CAPI) or a server-side tag manager, you're losing 30–50% of reported conversions, and the algorithm can't learn from them.
Swap polished ads for UGC
On TikTok and Instagram Reels, creator-style UGC outperforms polished brand ads by 2–3× on ROAS. The platforms reward content that looks native, not content that looks expensive.
Separate prospecting from retargeting
Running these in the same campaign confuses the algorithm and inflates your blended CPA. Separate the campaigns, separate the budgets, separate the creative. Retargeting needs urgency and proof; prospecting needs hook and curiosity.
Audit your landing page, not just your ads
Mobile ecommerce conversion rates in 2026 average 1.8–2.5% vs 3.5–4% on desktop. If your ads send mobile traffic to a desktop-optimised page, half your budget is funding bounces. Speed <2s, hero above fold, one clear CTA.
Frequently asked questions
For D2C e-commerce brands, a good blended ROAS is 3–4x. Prospecting campaigns typically achieve 2–3x ROAS, while retargeting hits 6–10x. For subscription products with high lifetime value, even 1.5–2x initial ROAS can be profitable when factoring repeat purchases over 12 months. For lead generation, ROAS isn't the key metric, cost per qualified lead and pipeline contribution matter more.
ROAS is revenue divided by ad spend, a ROAS of 4x means £4 revenue for every £1 spent on ads. ROI subtracts all costs (ad spend, agency fees, product costs, overheads) before dividing by investment, giving true profit percentage. ROAS is a campaign metric useful for comparing ads; ROI is a business metric useful for deciding whether the whole channel is worth it.
UK CPMs in 2026 typically range £4–£8 on TikTok, £8–£14 on Meta, £2–£8 on Pinterest, £10–£18 on YouTube, and £20–£45 on LinkedIn. UK CPCs run £0.30–£1.20 on TikTok and £0.50–£2.00 on Meta, varying by industry. Finance and beauty pay significantly more than apparel or food. All rates rose 8–12% year-on-year in 2025.
The formula is: ROI = ((Revenue − Total Cost) ÷ Total Cost) × 100. For social media, Total Cost includes ad spend, agency fees, creative production, and any tool subscriptions. A 200% ROI means you made £3 back for every £1 invested (the original £1 plus £2 profit). This is stricter than ROAS, a campaign can have 3x ROAS and still lose money once you add profit margin and overheads.
The usual suspects: audience saturation (hitting the same people repeatedly), creative fatigue (ads losing novelty after 2–3 weeks), rising CPMs (more competition in your vertical), and attribution gaps (iOS and ad blockers hiding 30–50% of conversions). Refresh creatives every 2–3 weeks, expand to new audiences, and implement Conversions API to stabilise ROAS.
Not alone. Meta's ROAS uses its own attribution window (typically 7-day click, 1-day view) and only counts conversions it can track. In practice this overstates ROAS by 15–30% for most brands. Cross-reference against your actual bank deposits and platform sales data monthly. The gap between Meta-reported and actual revenue is your real blended ROAS.
Yes, for lead gen you measure Cost per Lead (CPL) and Cost per Qualified Lead (CQL), then multiply through your sales funnel to get effective revenue. If your CPL is £25, lead-to-customer rate is 10%, and average customer value is £800, your effective ROAS is (£800 × 0.10) ÷ £25 = 3.2x. The calculator above handles this automatically in Lead Generation mode.
