**Classification framework:**

A useful test is the "dignity threshold" — would failing to fund this expense compromise the client's health, safety, legal obligations, or basic dignity? If yes, it is essential.

| Category | Essential | Discretionary |
|----------|-----------|---------------|
| Housing | Mortgage/rent, property tax, basic maintenance | Renovation, vacation home, luxury upgrades |
| Food | Groceries, basic dining | Fine dining, premium wine, catering |
| Healthcare | Insurance premiums, medications, dental | Elective procedures, premium supplements |
| Transportation | Reliable vehicle, insurance, fuel | Luxury car, frequent upgrades |
| Taxes | Income tax, property tax | Charitable giving (above baseline) |
| Insurance | Health, home, auto, umbrella | Whole life (beyond estate need) |
| Utilities | Electric, water, internet, phone | Premium streaming, smart home systems |
| Personal | Basic clothing, grooming | Designer clothing, spa services |

**The gray zone — client-specific classification:**

Consider two clients of advisor Nathan Brooks:

- **Sandra Keating**, 63, suburban Arizona: a car is essential (no public transit, medical appointments require driving). Annual auto cost: $8,400 → essential.
- **Michael Ferraro**, 63, Manhattan: subway pass is essential ($1,500/year), car ownership is discretionary ($14,000/year in parking, insurance, payments).

Same expense category, opposite classifications based on circumstances.

**Dynamic reclassification:**

Spending classifications should be reviewed as clients age. A fitness membership classified as discretionary at 65 might become essential at 78 when physical therapy and fall prevention become medical necessities. Travel classified as discretionary spending might be reclassified as essential for mental health by a geriatric care specialist.

**Exam application:**

When CFA Level III presents a case study, follow this process:
1. List all spending items
2. Apply the dignity threshold test
3. Consider client-specific circumstances (location, health, family obligations)
4. Separate into essential (fund with 90%+ probability) and discretionary (fund with 50-75% probability)
5. Size the floor portfolio to cover essentials

The rigor of this classification directly determines the quality of the retirement income strategy. Over-classifying items as essential creates an unnecessarily large floor (reducing upside potential), while under-classifying creates a floor that fails when markets decline.
