Supplements have the best retention economics of any consumer category. A 37.7% repurchase rate (inBeat DTC brand statistics, up from 33.1%), high gross margins from low COGS, and natural subscription mechanics create unit economics that other categories cannot match. The catch: regulatory compliance costs, platform advertising restrictions on health claims, and customer acquisition in a crowded market compress the advantage faster than expected.
These benchmarks are built from aggregated data across Finaloop (P&L benchmarks, 800+ brands), First Page Sage (CAC data, 80+ ecommerce clients, 2020-2025), MobiLoud/inBeat (retention and repurchase trends), and Genesys Growth (LTV:CAC benchmarks). If you run a supplements or wellness brand at $5M to $75M, these are the numbers to measure against.
The Retention Advantage
Supplements have the highest repurchase rate of any consumer category at 37.7% within a 24-month window, up from 33.1% in prior periods. For context, beauty sits at 25-30%, fashion at 20-25%, and home at 15-20%.
| Category | Repurchase Rate (24-month) | Trend |
|---|---|---|
| Supplements | 37.7% | Up from 33.1% |
| Food & Beverage | 25-35% | Drops by Month 6 |
| Beauty | 25-30% | Skincare higher than color |
| Fashion | 20-25% | Lowest consumable category |
This matters because repurchase rate is the single biggest lever on LTV, and LTV drives how much you can afford to spend on acquisition (Genesys Growth CAC benchmarks). A supplement brand with 37.7% repurchase and a subscription option has a structural economic advantage over a fashion brand at 22%, so supplements should produce the strongest LTV:CAC ratios of any consumer category. When they do not, the problem is almost always on the acquisition side. If your LTV:CAC is below 3:1 with a 35%+ repurchase rate, that is a clear signal: your retention economics are working and your acquisition is not. The next step is channel-level CAC tracking to find where the overspend is.
Subscription Economics
Supplements are the most natural subscription category in ecommerce. The product runs out on a predictable schedule (30, 60, or 90 days), the customer wants the same product again, and the reorder decision has low friction. This creates three specific economic advantages:
- Lower effective CAC. Acquisition cost is amortized over more orders. A $60 CAC spread over 8 subscription orders (2 years at quarterly refills) is an effective $7.50 per order, compared to $60 for a one-time buyer.
- Higher LTV. A subscription customer on a 90-day cycle at $45 per order generates $180 per year and $360 over 24 months. A one-time buyer generates $45.
- Predictable cash flow. Subscription revenue is recurring and forecastable, which improves cash planning and reduces the risk of inventory mismatches.
The key metric for subscription brands is subscription retention rate: what percentage of subscribers are still active at 6, 12, and 24 months. A brand adding 1,000 subscribers per month but losing 800 has a 20% monthly churn problem that no amount of acquisition spending can fix. The retention curve is the single most important chart in a supplement business.
Gross Margin
Supplements carry some of the highest gross margins in ecommerce, typically 65-80%. The COGS for a bottle of supplements is often $3-$8 per unit for products retailing at $25-$60. Contract manufacturing at scale drives per-unit costs down further.
| Rating | Gross Margin | What it means |
|---|---|---|
| Strong | >70% | Proprietary formulations, DTC-heavy |
| Healthy | 60-70% | Standard formulations, mixed channels |
| Warning | 50-60% | Heavy wholesale or ingredient cost pressure |
| Critical | <50% | Structural COGS or channel problem |
The margin advantage is real, but it comes with a caveat. Supplement brands often need to reinvest a larger share of gross profit into customer acquisition and compliance than other categories. A 75% gross margin that requires spending 35% of revenue on paid acquisition and 5-8% on regulatory compliance nets out to a contribution margin closer to other categories than the headline gross margin suggests. The high COGS margin can mask bad decisions elsewhere in the P&L, so the operating discipline is to track contribution margin as tightly as gross margin. If your gross margin is above 65% but your EBITDA is below 7%, that gap is where the diagnosis lives. Pull your marketing spend and compliance costs as separate line items to find it.
Contribution Margin
| Rating | Contribution Margin | Notes |
|---|---|---|
| Top Quartile | 54-56% | Best performers across categories |
| Healthy | 30-40% | Optimized DTC brands |
| Median | ~25% | Typical 7-8 figure brands |
| Critical | <15% | Unsustainable |
For supplement brands, the spread between gross margin and contribution margin is usually driven by two factors: marketing spend and fulfillment costs. Supplements are lightweight and non-fragile (low shipping costs), so fulfillment is a smaller drag than categories like beverages or furniture. The bigger variable is acquisition spending, which tends to run higher in supplements due to platform restrictions on health claims and intense competition.
EBITDA Margin
| Revenue Size | Median EBITDA | Target |
|---|---|---|
| $1M-$10M | 4% | 10%+ |
| $10M-$50M | 7-8% | 15%+ |
| $50M+ | 10-15% | 15-20% |
Supplement brands should produce higher EBITDA margins than most consumer categories given their gross margin advantage (Finaloop, 800+ brands; Hahnbeck DTC valuation data). The ones that do not usually have one of three problems: over-hiring (G&A bloat from building a team sized for $50M when the brand is doing $15M), a compliance cost burden that was never budgeted as a line item, or an acquisition cost structure that eats the margin advantage because the brand spread across too many paid channels before optimizing the core two. At the $10M-$50M range, G&A typically runs 18-22% of revenue (Finaloop, 800+ brands). If you are a supplement brand with 70%+ gross margin and sub-10% EBITDA, the operating exercise is to list every cost between gross profit and EBITDA, rank them by size, and ask which three you would cut if revenue dropped 20% tomorrow. Those three are your priority regardless.
LTV:CAC Ratio
| Rating | LTV:CAC | Interpretation |
|---|---|---|
| Strong | >4:1 | Efficient acquisition, room to invest |
| Healthy | 3:1 to 4:1 | Sustainable unit economics |
| Warning | 2:1 to 3:1 | Tight margins |
| Critical | <2:1 | Losing money on acquisition |
Supplements should be one of the strongest LTV:CAC categories given the 37.7% repurchase rate and subscription mechanics. The target is 3:1 minimum after three years in business, measured over a 36-month customer window (not an unfalsifiable "lifetime" assumption). With subscription models pushing effective customer lifetime to 18-24+ months, well-run supplement brands can reach 5:1 or better. If your LTV:CAC is below 3:1 in supplements, the issue is almost always acquisition efficiency. The deeper issue is usually brand differentiation: in a crowded category, the brands that keep CAC manageable are the ones with a clear point of view that the customer can describe in one sentence. Generic formulations with generic positioning produce generic CAC.
What Good Looks Like
Gross margin above 68%. Contribution margin above 32%. EBITDA margin above 12%. LTV:CAC above 4:1. Repurchase rate above 35% at 24 months. Subscription rate above 40% of revenue. Subscription churn below 8% monthly. Regulatory compliance costs budgeted and tracked as a line item. Customer acquisition from organic and retention channels exceeding 30% of total. G&A below 18% of revenue.
Warning Signs
EBITDA margin below 5% despite 70%+ gross margin (the margin advantage is being consumed by spending). Subscription churn above 12% monthly. LTV:CAC below 3:1 in a high-retention category (acquisition is broken). More than 80% of new customers from paid channels. No budget line for regulatory compliance. Health claims on packaging or advertising that have not been reviewed by counsel. Inventory aged 180+ days (supplements have expiration dates).
Category-Specific Insights
1. Regulatory compliance is a real cost center, not an afterthought
FDA requirements for dietary supplements include current Good Manufacturing Practices (cGMP), adverse event reporting, and specific labeling requirements. FTC scrutinizes health claims in advertising. Third-party testing (NSF, USP, or equivalent) adds credibility but also cost. A supplement brand at scale should budget $50K-$200K+ annually for compliance-related costs including testing, legal review, and claim substantiation. Founders who treat this as a cost to defer are building on a foundation that a single FDA warning letter can crack.
2. Platform advertising restrictions change the acquisition playbook
Meta and Google both restrict health claims in supplement advertising. This limits the creative and targeting options available to supplement brands compared to fashion or beauty. The brands that succeed at acquisition work around these restrictions through educational content, influencer partnerships, and organic SEO that drives traffic to owned properties where health claims can be supported with proper disclaimers. Paid acquisition is possible but requires more creative sophistication than most other categories.
3. The COGS advantage is real but can mask bad decisions
When your product costs $4 to make and sells for $40, it is easy to feel comfortable. That 90% markup on COGS gives the illusion of wide operating room. But once you add shipping ($3-$5), payment processing ($1.20-$1.60), acquisition cost ($15-$25 per order on a blended basis), and packaging ($2-$4), that $36 of gross profit becomes $12-$18 of contribution margin. The operating question to ask yourself: "If my gross margin dropped to 55% tomorrow, would my business still be profitable?" If the answer is no, then the high COGS margin is subsidizing a cost structure that needs to be fixed regardless.
4. Subscription retention is worth more than subscription acquisition
Adding 500 subscribers per month is meaningless if 400 are canceling. Every month a subscriber stays active, the effective CAC per order decreases and the lifetime value increases. The operating move that consistently outperforms adding more subscribers: investing in the subscription experience itself. Easy customization, skip/pause flexibility instead of cancel-only options, personal dosage guidance, and regular flavor or format drops that give existing subscribers a reason to stay engaged. The brands with the strongest subscription retention curves treat the subscriber experience as a product, and the brands stuck on the acquisition treadmill typically have not.
Pull these 3 numbers from your Shopify, subscription platform, and accounting system: subscription revenue as a percentage of total, monthly subscriber churn rate, and paid acquisition as a percentage of total new customers. If subscription revenue is below 30% of total, you are leaving your strongest economic lever on the table: invest in subscription onboarding and conversion before spending more on acquisition. If monthly churn is above 10%, the priority is subscriber experience (skip/pause flexibility, customization, dosage guidance), not subscriber volume. If paid acquisition accounts for more than 75% of new customers, your brand is too dependent on rented channels: invest in organic, email, and content to build a customer base you own.
