Multi-Generational Bridge: Retaining Assets Across Generations
The maths behind generational AUM attrition — and the retention value equation that makes heir engagement a quantifiable investment.
An estimated €70 trillion in wealth is projected to transfer between generations globally over the next two decades. Research consistently shows that 70–80% of heirs switch advisors within one year of receiving an inheritance — not because of poor performance, but because no prior relationship exists. This guide quantifies the revenue at risk, models the retention economics, and outlines engagement strategies with measurable outcomes.
The Attrition Formula
AUM at risk = Client AUM × Transfer probability × Heir attrition rate Annual revenue at risk = AUM at risk × Advisory fee rate (%)
| Client AUM (€) | Transfer prob. | Attrition rate | AUM at risk (€) | Revenue at risk @ 0.75% |
|---|---|---|---|---|
| 500,000 | 80% | 75% | 300,000 | €2,250/yr |
| 2,000,000 | 80% | 75% | 1,200,000 | €9,000/yr |
| 5,000,000 | 80% | 75% | 3,000,000 | €22,500/yr |
| 10,000,000 | 80% | 75% | 6,000,000 | €45,000/yr |
The Retention Value Equation
Net retention value = (AUM retained × Fee rate × Relationship years)
− Heir engagement costThe Three-Horizon Engagement Framework
Horizon 1: Foundation (10–15 years pre-transfer)
- Map the full family structure and identify primary heirs
- Introduce the firm to adult heirs in an educational, non-sales context
- Offer financial literacy resources tailored to heir life stage
Horizon 2: Integration (3–9 years pre-transfer)
- Include heirs in annual family financial review meetings (with client consent)
- Begin relationship-building with heirs as prospective clients in their own right
- Document family wealth structure in an accessible format
Horizon 3: Transition (0–2 years, transfer event)
- Execute proactive outreach immediately upon transfer trigger
- Offer a dedicated heir onboarding process distinct from the parent’s file
- Assign a relationship manager familiar with the family context
What-If Scenarios
On a €2M estate, AUM retained increases from €400K to €1.2M. Additional annual revenue (at 0.75%) = €6,000. Over 20 years, this represents ~€120,000 in additional gross revenue per client relationship.
For 20 high-value clients (avg. €3M AUM), total cost = €100,000/year. If the programme retains 50% of otherwise-lost AUM across 5 transitioning estates per year, retained AUM ≈ €3.75M/yr, generating €28,125 additional annual revenue. Payback ~3.5 years.
Conversion rate drops markedly to 15–25% vs. 50–65% where no prior relationship exists. Early engagement — before the heir has established their own advisory relationship — is significantly more effective than post-transfer outreach.
