## DTC unit economics matters

DTC brands live and die on unit economics. The pandemic-era DTC boom collapsed brands that scaled without economics. The winners had relentless discipline: every customer acquisition justified by lifetime contribution, every order generating cash that fueled the next.

## AOV and order economics

| Component | Why it matters |
| --- | --- |
| AOV | Higher AOV absorbs CAC better |
| Gross margin | Determines contribution per order |
| Shipping cost | Often eats 5–15% of revenue |
| Returns rate | Lower-margin categories devastated by returns |
| Payment processing | 2–3% of revenue typical |
| Cart abandonment recovery | Boosts effective AOV |

## CAC: blended and channel-level

- **Blended CAC:** Total marketing spend / new customers (including organic).
- **Paid CAC:** Paid spend / paid-attributed new customers.
- **Marketing-loaded CAC:** Include team, tools, content.
- **Channel-level CAC:** Per channel; informs allocation.
- **New customer focus:** Don't blend existing customer programs into acquisition CAC.

## LTV: cohort-based

- **Don't use average lifespan × ARPU.** Cohort-based LTV is what matters.
- **Sum future revenue per cohort.** Discounted by retention curve.
- **Cohort by acquisition source.** Channel quality varies.
- **Predicted LTV.** ML models from early behavior predict eventual LTV.
- **Gross profit LTV, not revenue LTV.** COGS, shipping, returns deducted.

## Payback period

- Time to recover CAC from gross profit.
- **DTC sweet spot:** 3–6 months.
- **Subscription DTC:** Can extend to 12 months with confidence in retention.
- Long payback = capital intensive; only sustainable with strong retention and reserves.

## Contribution margin

- Revenue − (COGS + shipping + processing + returns + variable marketing).
- **Healthy DTC:** 30–50% contribution margin.
- Below 20%: structural problem with product, pricing, or operations.
- Contribution margin per order; per cohort; per channel.

## Cohort analysis

- Retention curve per acquisition cohort.
- Revenue accumulation curves.
- Source-based cohorts (paid social vs organic vs referral).
- Behavioral cohorts (first product, discount used, repeat rate).
- Quarterly cohort review informs allocation.

## Cash conversion cycle

- Days from cash out (inventory + media) to cash in (customer payment).
- Inventory days + AR days − AP days.
- DTC ecommerce typically positive cash cycle (customer pays before AP due).
- Subscription DTC: faster cash because recurring payments.
- Cash discipline matters because reaching profitability often requires bridging.

## Advanced playbook

- **Channel-level full P&L.** Each channel modeled with full unit economics.
- **LTV by source-cohort dashboards.** Track quality of acquisition by channel.
- **Predictive LTV from first 7-30 days.** Allows confident bidding.
- **Subscription option for replenishment.** Lifts LTV and retention.
- **AOV optimization.** Free shipping thresholds, bundles, upsells.
- **Returns reduction.** Better photography, fit guides, reviews.
- **Contribution-margin-aware media bidding.** Bid against contribution, not revenue.
- **Discount discipline.** Tracks LTV of discount-acquired vs full-price.
- **Cash flow modeling.** Forecasts cash position; informs working capital.
- **Annual unit economics review with board.** Strategic alignment on growth vs profitability.

## Common mistakes

- Revenue-LTV not gross-profit-LTV.
- Average-lifespan LTV instead of cohort-based.
- Blended CAC reported without channel breakdown.
- Working media CAC only; team and tools omitted.
- Discount-acquired customers' LTV not tracked.
- Returns rate omitted from contribution margin.
- Shipping subsidies not reflected in contribution.
- Cash conversion cycle ignored.
- Payback period too long without capital strategy.
- Subscription not offered for consumables.
- Channel allocation by ROAS instead of contribution margin.
- Growth-at-any-cost without unit economics gate.

## Operating checklist

- Gross-profit LTV (not revenue LTV)
- Cohort-based LTV per acquisition source
- Channel-level CAC including team/tools
- Contribution margin per order
- Payback period tracked monthly
- Cash conversion cycle tracked
- Predictive LTV model for bidding
- Subscription offered for consumables
- Returns rate tracked per product/category
- Discount-acquired LTV tracked separately
- Quarterly cohort review
- Channel-level full P&L modeling
