## How Endowment Spending Works

Endowments are designed to provide perpetual funding. The spending rate must be low enough that investment returns preserve the real (inflation-adjusted) value of the endowment.

### Formula

**Annual Spending = Endowment Value x Spending Rate**

**Sustainable if Spending Rate <= Expected Return - Inflation**

### Common Practice
- Most institutions spend 4-5% annually
- The "Yale Model" suggests 5.25% with a diversified portfolio
- Spending above the real return rate erodes the endowment over time

हल किया गया उदाहरण

A $50M endowment with 5% spending rate, 7% expected return, 3% inflation.

  1. Annual spending: $50M x 0.05 = $2,500,000
  2. Real return: 7% - 3% = 4%
  3. Spending (5%) > Real return (4%): Not sustainable long-term
  4. Net growth: $50M x (7 - 5 - 3)/100 = -$500,000 per year
