Model Comparison

PSC:
Endowments++

PSC isn't a replacement for endowments—it's an upgrade. You get perpetual funding, legacy naming, and capital preservation—plus 22× more system value over 30 years. Allocate some or all of your capital to PSC alongside traditional endowments.

Same Benefits, Better Mechanics

Both preserve capital in perpetuity. PSC just does it more efficiently—and you can use both.

Traditional Endowment

Locks capital in investments. Deploys only the returns (4-5% annually). The principal stays untouched "forever."

Capital preserved in perpetuity
Predictable annual distributions
95% of capital sits idle each year
Subject to market volatility
High management fees (0.5-2%)
30-Year Total Deployed
~$150,000
(from $100K initial)

Perpetual Social Capital

Everything endowments offer—perpetual funding, legacy naming, capital preservation—plus 100% immediate deployment and compounding impact.

Capital preserved in perpetuity (via recycling)
Legacy naming & recognition available
100% deployed immediately (not 5%)
Impact compounds each cycle
Not tied to market volatility
No management fees
30-Year System Value (R=0.95)
$2,670,000
(26.7× from $100K initial)

30-Year Cumulative Deployment

Starting with $100,000, see how much capital actually works for beneficiaries.

Endowment: 5% annual payout | PSC: R=0.9, 3-year cycles

It Doesn't Have to Be Binary

Many foundations allocate a portion of their capital to PSC while maintaining a traditional endowment. Start with 10-20% and adjust based on results.

Conservative
80% Endowment / 20% PSC

Keep most capital in traditional endowment for predictability. PSC portion amplifies impact on suitable programs.

Balanced
50% Endowment / 50% PSC

Split approach maximizes both stability and impact. Best for foundations with diverse program types.

Aggressive
20% Endowment / 80% PSC

Maximum system value. Keep small endowment for overhead and emergency funds. Deploy the rest through PSC.

When to Keep Some in Traditional Endowment:

  • Programs where beneficiaries cannot pay forward (emergency relief, end-of-life care)
  • Covering operational overhead that needs predictable annual funding
  • Maintaining a reserve for unexpected opportunities or crises

The Theoretical Foundation

Why does PSC outperform endowments? The Regenerative Capital Theory paper explains the fundamental difference: endowments use extractive logic (invest → extract returns → deploy some), while PSC uses regenerative logic (deploy → benefit → recycle). This isn't just different mechanics—it's a different relationship between capital and beneficiaries.
