Ecommerce Metrics Every DTC Founder Should Track

Most DTC founders check two numbers: revenue and ad spend. Revenue went up? Good day. ROAS above 3? Open a beer. Everything else gets ignored until something breaks.

This works until it doesn't. You can grow revenue 40% in a quarter and still lose money. I have watched it happen. High return rates, rising CAC, and thin margins can eat a business alive while the top-line number looks fantastic.

Here are the eight metrics that separate DTC brands that scale from DTC brands that go under. With real benchmarks so you know where you stand.

1. Contribution Margin

This is the number that tells you whether your business actually makes money on each order. Revenue minus COGS minus fulfillment minus payment processing minus ad spend for that order. What is left after every variable cost.

If your contribution margin is negative, you are paying customers to buy from you. No amount of volume fixes that. You need to either raise prices, cut fulfillment costs, or reduce ad spend per acquisition.

Benchmark: Healthy DTC brands run 15-25% contribution margin after ad spend. Below 10% and you have almost no room for error. Above 30% and you are in excellent territory.

2. Average Order Value (AOV)

Total revenue divided by number of orders. Simple math, but the strategic implications are huge. Higher AOV means you can afford higher CAC. It means each customer interaction generates more gross profit. It means your margins on shipping and fulfillment improve because those costs do not scale linearly with order value.

The lever most founders miss: bundles. A customer who buys one product for $40 costs you nearly the same in fulfillment as a customer who buys two products for $72. But the second order has dramatically better economics.

Benchmark: Varies wildly by category. Apparel averages $80-120. Beauty and skincare $50-75. Home goods $100-200. Track your own trendline. A rising AOV quarter over quarter is more important than hitting a specific number.

3. ROAS (Return on Ad Spend)

Revenue generated per dollar spent on ads. A 3x ROAS means you spent $1,000 on ads and generated $3,000 in revenue. Sounds great until you remember that revenue is not profit. If your margins are 30%, that $3,000 in revenue is $900 in gross profit. You spent $1,000 to make $900. You lost money.

ROAS is only meaningful in the context of your margins. A 2x ROAS on a 70% margin product is better than a 4x ROAS on a 20% margin product. Too many founders celebrate ROAS without doing the margin math.

Benchmark: Blended ROAS across all channels: 3-5x is solid for most DTC brands. Below 2x is usually unprofitable. Above 5x usually means you are under-spending and leaving growth on the table.

4. Customer Acquisition Cost (CAC)

Total marketing spend divided by new customers acquired. Not just ad spend. Include your agency fees, your creative production costs, influencer payments, affiliate commissions. Everything it costs to bring a new customer through the door.

The honest version of this number is almost always higher than what founders quote. When you include the creative agency, the photography, and the email platform, a $30 CAC quickly becomes $48.

Benchmark: Depends entirely on your LTV. The rule of thumb is LTV-to-CAC ratio of 3:1 or better. If your average customer is worth $150 over their lifetime, you can afford to spend $50 to acquire them.

5. Customer Lifetime Value (LTV)

How much revenue a customer generates before they stop buying from you. The simplest formula: average order value multiplied by average number of purchases over 12 months (or 24, depending on your cycle).

LTV is the number that determines how aggressively you can acquire customers. A DTC brand with $200 LTV can outspend a competitor with $60 LTV on every single channel, even if their product is worse. That is why brands obsess over repeat purchases. One-time buyers are expensive. Repeat buyers are where the money actually lives.

Benchmark: Top DTC brands see 2.5-4x repeat purchase multiplier over 24 months. If your AOV is $80 and customers buy 3 times, your LTV is $240. Brands below 1.5x usually struggle with profitability.

6. Repeat Purchase Rate

Percentage of customers who buy a second time. This is the leading indicator that tells you whether your product is good enough to build a business on. High first-order volume with low repeat rates means your marketing is working but your product is not.

Track this at 30, 60, and 90 day intervals after first purchase. If repeat rates are flat or declining, fix the product before scaling acquisition. Scaling a leaky bucket just makes a bigger mess.

Benchmark: 25-30% repeat purchase rate within 90 days is good for most DTC categories. Consumables (skincare, supplements, food) should aim for 35-45%. Below 20% and you have a retention problem that no amount of email marketing will fix.

7. Return Rate

The metric nobody talks about in their investor deck. Returns eat your margins twice: you refund the revenue and eat the shipping cost. A 25% return rate on a product with 50% gross margin means your effective margin is closer to 30% when you account for reverse logistics.

High return rates usually signal one of three things: misleading product photos, poor sizing information (apparel), or quality issues. All fixable, but only if you track the number.

Benchmark: Apparel runs 20-30% returns (brutal industry). Electronics 10-15%. Beauty and consumables under 5%. If you are significantly above your category average, you have a product or messaging problem.

8. Conversion Rate

Percentage of site visitors who complete a purchase. The multiplier on everything else. A 1% improvement in conversion rate does more for your bottom line than a 10% increase in traffic, because the traffic you are already paying for starts converting better.

Track this by source. Your Instagram traffic might convert at 0.8% while your email traffic converts at 4.5%. Blended conversion rate hides where the real performance (and real problems) live.

Benchmark: Average ecommerce conversion rate sits around 2.5-3.5%. Top DTC brands hit 4-6%. Below 1.5% and you likely have a landing page, pricing, or trust problem.

Putting It Together

These eight metrics form a complete picture. Contribution margin tells you if the business works. AOV and LTV tell you how much each customer is worth. CAC and ROAS tell you what it costs to get them. Repeat purchase rate tells you if they stick around. Return rate tells you if the product delivers. Conversion rate tells you if your site does its job.

Most ecommerce analytics tools only cover half of these, or they cover them without connecting the dots. Kartib has an ecommerce dashboard mode that tracks all eight in one view, with auto-calculated contribution margins and LTV-to-CAC ratios. No Shopify plugin required. You enter your data, and the KPI engine handles the rest.

Check these weekly. Not monthly. By the time you notice a bad month, the damage is done. Weekly reviews let you catch problems while they are still small enough to fix.
