E-commerce KPIs: The 25 Metrics Every DTC Brand Should Track in 2026

The 25 e-commerce KPIs that matter most for DTC brands fall into five categories: acquisition, retention, revenue, profitability, and engagement. Tracking the right metrics is not about monitoring everything available. It is about focusing on the metrics that directly inform decisions and drive profitable growth.

Too many brands track vanity metrics like total revenue, follower count, or page views without connecting them to anything that actually moves the business. Each metric below answers a specific business question: are we acquiring customers efficiently, are they coming back, are they profitable. The list is organized so you can find the metrics that matter for your stage and start tracking them.

Acquisition metrics

How efficiently you attract and convert new customers.

1. Customer Acquisition Cost (CAC)

The total cost to acquire one new customer, including all marketing and sales spend. CAC = Total Marketing and Sales Spend / Number of New Customers Acquired.

Mid-market DTC sits at $30-60. Beauty and skincare run $40-50, apparel $50-70, supplements $35-55. CAC determines whether your unit economics work at all. If your CAC exceeds first-order contribution margin, you need repeat purchases to break even, which puts the entire weight of profitability on retention.

2. Return on Ad Spend (ROAS)

Revenue per dollar of ad spend. ROAS = Revenue from Ads / Ad Spend. Healthy DTC ranges: 3-5x for prospecting, 5-10x for retargeting, blended 4x.

Track it by channel and campaign. Aggregate ROAS hides the campaigns that are quietly bleeding money.

3. Cost Per Acquisition (CPA)

The cost to acquire a specific action, usually a purchase but sometimes a lead or signup. CPA = Total Campaign Cost / Number of Conversions. For purchases, often used interchangeably with CAC. For lead actions like email signups, $5-15 is typical.

CPA is the channel-level view of acquisition efficiency that complements blended CAC.

4. Conversion Rate

Conversion Rate = (Number of Orders / Number of Sessions) x 100. The DTC average is 2-3%, top performers hit 4-5%, and mobile typically converts 40-50% lower than desktop.

This is one of the highest-impact numbers on the site. A brand with 100,000 monthly visitors at 2% generates 2,000 orders. Moving to 3% generates 3,000 orders, a 50% revenue lift with zero added ad spend. We have seen brands ignore conversion rate for years because they were busy buying more traffic.

5. Cost Per Click (CPC)

The average cost per click on a paid ad. CPC = Total Ad Spend / Total Clicks. Facebook and Instagram run $0.50-2.00, Google Search $1.00-3.00 for DTC verticals, TikTok $0.30-1.00.

CPC is an input that feeds CPA and CAC. Rising CPCs usually signal increased competition or fading ad relevance.

Retention metrics

How well you keep customers engaged and purchasing over time.

6. Churn Rate

The percentage of customers (or subscribers) who stop purchasing or cancel within a given period. Churn Rate = (Customers Lost During Period / Customers at Start of Period) x 100.

Subscription e-commerce typically runs 5-8% monthly churn. 2-4% is excellent, above 10% is a fire. Reducing monthly churn from 8% to 5% takes average customer lifespan from 12.5 months to 20, a 60% improvement that flows straight into LTV. Retention intelligence helps surface what is actually causing the churn.

7. Retention Rate

The percentage of customers active in a defined period. Retention Rate = ((Customers at End of Period - New Customers Acquired) / Customers at Start of Period) x 100.

DTC brands target 30-40% 12-month retention. Subscription brands with strong product-market fit clear 50%. When this number declines, it is almost always pointing at product issues, competitive pressure, or a deteriorating experience, not marketing.

8. Repeat Purchase Rate

Repeat Purchase Rate = (Customers with 2+ Orders / Total Customers) x 100. Average DTC sits at 25-30%. Consumables hit 35-45%, durables 15-20%. Full breakdown in our guide to repeat purchase rate.

The most direct measure of customer loyalty and product satisfaction, and a strong leading indicator of LTV.

9. Customer Health Score

A composite metric (typically 0-100) that combines recency, frequency, monetary value, engagement, and support interactions into a single score per customer. See our customer health score guide for the formula.

Aim for 60%+ of active customers in healthy territory (score above 60). Watch the distribution, not just the average. The reason this matters is forward-looking: a health score lets you act on at-risk customers before churn shows up in the lagging numbers.

10. Time Between Purchases

The average days between a customer's consecutive orders. Time Between Purchases = Total Days Between All Consecutive Orders / Total Number of Repeat Purchases.

Consumables run 30-45 days, apparel 60-90, durables 180+. Knowing your real cadence is what makes win-back campaigns and replenishment reminders work, and it is what lets you define churn correctly instead of using an arbitrary 90-day window.

Revenue metrics

The revenue performance of your business.

11. Monthly Recurring Revenue (MRR)

The predictable, recurring revenue from subscriptions each month. MRR = Active Subscribers x Average Revenue Per Subscriber. Track growth rate, not the absolute number. 10-20% month-over-month is strong for early-stage, 5-10% for scaling brands.

The number that matters more than top-line MRR is the breakdown: new MRR, expansion MRR, contraction MRR, and churned MRR. That is where you actually see what is driving growth or hiding decline.

12. Annual Recurring Revenue (ARR)

ARR = MRR x 12. Used primarily for valuation and planning. Strong early-stage subscription brands grow ARR 2-3x year-over-year. Mostly relevant when you are raising money or building a long-term plan.

13. Average Order Value (AOV)

AOV = Total Revenue / Number of Orders. Mid-market DTC sits at $50-80. Beauty $45-65, supplements $40-60, apparel $65-100, home goods $80-150.

One of three levers in the LTV equation along with purchase frequency and lifespan. Lifting AOV through upselling, cross-selling, and bundling flows directly into LTV without requiring more customers or more retention.

14. Customer Lifetime Value (CLV)

CLV = AOV x Purchase Frequency x Customer Lifespan. A healthy CLV:CAC ratio is 3:1 or higher. DTC CLV typically lands between $100 and $400 depending on category and retention. See our guide to increasing CLV.

This is the single most important metric for sustainable growth. It defines how much you can spend on acquisition, retention, and product without breaking unit economics. At Scentbird we ran the entire business off LTV by cohort.

15. Revenue Per Visitor (RPV)

RPV = Total Revenue / Total Website Sessions. $2-5 is typical for DTC.

RPV is conversion rate and AOV in one number. It is the cleanest way to evaluate traffic quality and site effectiveness, because either lever moving in the wrong direction will show up here.

Profitability metrics

Whether your revenue translates to actual profit.

16. Contribution Margin

Revenue minus variable costs (COGS, shipping, payment processing, returns) per order or as a percentage. Contribution Margin = Revenue - Variable Costs.

Owned manufacturing brands run 40-60%, contract manufacturing 25-40%, resellers 15-25%. Contribution margin is what determines whether you can afford your CAC. If margin on a first order is $30 and CAC is $45, you are paying $15 to acquire each customer and praying for repeat purchases. Profit intelligence tracks this at the customer and product level.

17. COGS Ratio

Cost of goods sold as a percentage of revenue. COGS Ratio = (COGS / Revenue) x 100. DTC brands typically run 25-40%. Below 30% is strong. Above 50% leaves almost nothing for marketing and operations.

Watch this at the product level. Some products in your catalog are quietly subsidizing the rest, and unless you look, you will not know which.

18. CAC Payback Period

The number of months to recoup acquisition cost. CAC Payback = CAC / (Average Monthly Revenue per Customer x Contribution Margin %).

Under 6 months is strong, 6-12 is acceptable, over 12 means your acquisition costs are too high relative to what customers generate. Payback period also drives your cash flow needs. A 3-month payback lets you reinvest fast. A 12-month payback means you need working capital just to grow.

19. Return Rate

Return Rate = (Returned Orders / Total Orders) x 100. Apparel runs 10-15%, beauty and consumables 3-5%, footwear 8-12%. DTC average is 8-10%.

Returns eat contribution margin directly. A 30% return rate on apparel can flip a profitable order into a loss once you factor in shipping, restocking, and inventory write-downs.

20. Gross Margin

Gross Margin = ((Revenue - COGS) / Revenue) x 100. Owned manufacturing 60-75%, contract manufacturing 50-65%, resellers 35-50%.

The starting point for every profitability question. It tells you how much money is available for marketing, operations, and profit before any of it gets allocated.

Engagement metrics

How customers interact with your brand outside of purchase events.

21. Email Open Rate

Email Open Rate = (Emails Opened / Emails Delivered) x 100. 20-30% for promotional, 40-60% for transactional, 30-40% for lifecycle flows.

Apple Mail Privacy Protection inflates open rates, so this metric is less reliable than it used to be. Use it as a directional signal of list health and lean on click rates for accuracy.

22. Email Click-Through Rate (CTR)

Email CTR = (Emails Clicked / Emails Delivered) x 100. 2-4% for promotional, 3-6% for lifecycle. A click-to-open rate of 10-15% is healthy.

The most reliable email engagement metric in the post-iOS 15 era. It actually measures whether your content drove an action, not whether a privacy proxy fetched the open pixel.

23. Site Sessions Per Customer

Site Sessions Per Customer = Total Sessions from Known Customers / Number of Active Customers. Engaged brands see 3-5 sessions per customer per month.

Track the trend more than the absolute number. Customers who visit regularly are dramatically more likely to purchase and dramatically less likely to churn.

24. Net Promoter Score (NPS)

NPS = % Promoters (9-10) - % Detractors (0-6). 30-50 is good for DTC, 50-70 is excellent, above 70 is rare.

The best single-question predictor of word-of-mouth and loyalty. Brands with NPS above 50 see repeat purchase rates roughly 2x those of brands below 30.

25. Customer Satisfaction Score (CSAT)

The percentage of customers who rate their experience as satisfactory (typically 4-5 on a 5-point scale). CSAT = (Satisfied Responses / Total Responses) x 100.

75-85% is good, 85-95% is excellent, below 70% indicates systemic experience issues. Where NPS measures overall loyalty, CSAT pinpoints where in the journey the experience is breaking down. Run it post-purchase, post-support, and post-delivery to find the problem touchpoints.

Building your metrics dashboard

Not every brand needs all 25 metrics on day one. Prioritize by stage.

Early stage (under $1M revenue)

CAC, ROAS, Conversion Rate, AOV, Contribution Margin, Repeat Purchase Rate.

Growth stage ($1-10M revenue)

Add CLV, Churn Rate, MRR, CAC Payback Period, Email CTR, NPS.

Scale stage ($10M+ revenue)

Add Customer Health Score, RPV, Time Between Purchases, Gross Margin, COGS Ratio, Site Sessions.

Finsi's profit intelligence and retention intelligence track these automatically, connect them to specific customers and segments through smart segmentation, and surface the actions worth taking. That was the whole point of building it: less time in spreadsheets, more time on decisions.

Frequently asked questions

What KPIs should I track for my e-commerce store?

It depends on your stage. Early-stage brands (under $1M) should focus on six core metrics: CAC, ROAS, Conversion Rate, AOV, Contribution Margin, and Repeat Purchase Rate. Past $1M, add CLV, Churn Rate, MRR, and CAC Payback Period. At $10M+, layer on Customer Health Score, Revenue Per Visitor, and Time Between Purchases. The point is tracking metrics that inform decisions, not vanity numbers like total page views. Founders building their first analytics stack should start with the early-stage set and expand as the business matures.

What is a good conversion rate for e-commerce?

The DTC average is 2-3%. Top performers hit 4-5%. Mobile conversion typically runs 40-50% lower than desktop, so if your traffic skews mobile, a blended 2% can still be healthy. Conversion rate is one of the highest-impact metrics you can move. Going from 2% to 3% is a 50% revenue increase with zero additional ad spend. Focus on product pages, checkout flow, and page speed.

How many KPIs should an e-commerce brand track?

Most brands should actively monitor 6-12 KPIs depending on stage and complexity. Tracking too few leaves blind spots. Tracking too many creates noise that buries the signals worth acting on. The 25 metrics in this guide are comprehensive, but they are meant to be adopted progressively. Start with the metrics that answer your most urgent questions, then add more as your growth team builds capacity to act on them.

What is the difference between KPIs and metrics in e-commerce?

All KPIs are metrics. Not all metrics are KPIs. A metric is any measurable data point: page views, email opens, social followers. A KPI is a metric tied to a critical business objective. Total website sessions is a metric, but Conversion Rate is a KPI because it directly measures how effectively you turn traffic into revenue. The distinction matters because tracking too many metrics as if they were KPIs dilutes focus.

What are the best tools for tracking e-commerce KPIs?

Most brands stitch KPI tracking together from multiple tools: Shopify Analytics for store metrics, Google Analytics for traffic, ad platform dashboards for acquisition. The trouble is that the most valuable insights come from connecting metrics across systems, like understanding how CAC relates to CLV by acquisition channel, or how retention varies by customer segment. Platforms like Finsi's profit intelligence and retention intelligence unify the metrics, link them to individual customers via smart segmentation, and surface recommendations.
