The 12 KPIs Every Ecommerce CFO Tracks on the Dashboard
The minimum-viable KPI dashboard for a DTC or marketplace brand: 12 metrics, why each matters, healthy ranges, and how often to refresh.
An e-commerce CFO dashboard is one screen of decision metrics – margin, cash, acquisition efficiency and inventory – refreshed on a fixed cadence.
- Applies to
- Founders drowning in platform analytics but still unable to answer "are we making money this month".
- The short list
- Net revenue, contribution margin %, MER/ROAS, CAC and payback, repeat rate, AOV, return rate, inventory cover, cash on hand, runway, EBITDA, cash conversion.
Bottom line: Twelve metrics with owners beat sixty on a wall. If nobody changes a decision because of a number, it does not belong on the dashboard.

Most DTC dashboards we inherit have either 4 vanity metrics (revenue, sessions, ROAS, AOV) or 60 numbers nobody reads. The right answer is 12 – enough to run the business, few enough that the founder actually looks at them every Monday.
Growth & demand
1. Net revenue (after returns & discounts)
Gross revenue is a marketing metric. Net revenue – after refunds, chargebacks and promo discounts – is what hits the bank. Track weekly, compare YoY, not MoM.
2. New vs returning customer split
Healthy DTC brands sit at 35–50% returning customers after year 2. Below 25% means you're renting customers from Meta. Above 60% means you've stopped acquiring.
Marketing efficiency
3. MER (Marketing Efficiency Ratio)
Total revenue ÷ total ad spend. The honest version of ROAS – includes organic and brand spillover. Healthy: > 3.0 for established brands, > 4.0 for early stage.
4. Blended CAC
Total marketing spend ÷ new customers acquired. The number that actually determines payback, not platform-reported CAC.
5. CAC payback period (days)
Days until cumulative gross profit per cohort = CAC. Target < 60 days for sustainable scale, < 30 days if you're using debt to fund growth.
Unit economics
6. Contribution margin %
Net revenue − COGS − fulfillment − payment fees − returns, divided by net revenue. Target > 30%. Below 25% and ad spend can't scale profitably.
7. LTV (12-month, by cohort)
Average gross profit per customer over their first 12 months. Track by acquisition cohort – blended LTV averages hide the truth.
8. LTV/CAC ratio
Healthy: ≥ 3.0. Below 2.0 you're losing money on every customer. Above 5.0 you're probably underspending on growth.
Profitability
9. % of SKUs profitable (fully loaded)
Most brands have 15–25% of SKUs losing money once all costs are loaded. Track this number – if it goes up, kill SKUs.
Cash & inventory
10. Cash runway (weeks)
Current cash ÷ average weekly burn. Anything under 16 weeks needs a board-level conversation.
11. Inventory turn (annualized)
Annual COGS ÷ average inventory at cost. Healthy DTC: 4–8x. Below 3x = trapped cash. Above 12x = you're stocking out.
12. Days of inventory on hand
365 ÷ inventory turn. Combined with cash runway, this is your early-warning system for working-capital trouble.
Refresh cadence
- Daily: revenue, MER, CAC (automated)
- Weekly: cash, LTV cohorts, SKU profitability flags
- Monthly: full P&L, contribution margin, inventory turn
If your current dashboard doesn't cover these 12, you're flying with half the instruments. We build this stack as part of every fractional CFO engagement.
Frequently asked questions
How many KPIs should a founder actually track?
About a dozen: enough to cover growth, margin, cash and efficiency, few enough that every number has an owner and drives a decision.
How often should the dashboard update?
Cash and paid-media efficiency weekly; margin, inventory and cohort metrics monthly with the close.
What is the most commonly missing KPI on founder dashboards?
Contribution margin after fulfilment and ads, plus days of inventory on hand. Revenue and ROAS are usually there; the two that predict cash usually are not.
