Methodology, benchmarks and frequently asked questions
Free AUM Portability Calculator | Portability Score™
Portability, defined as a private banker's ability to transfer client assets when changing employer, is the single most important variable in any senior career move in wealth management.
A relationship manager with CHF 350m AUM does not automatically control CHF 350m of portable assets. The actual portable fraction depends on where that AUM sits, how deep the personal client relationship runs versus the bank brand, whether competitors have already approached those clients, and whether non-solicitation obligations create a lock-out window.
The Portability Score™ is a structured decision-support framework informed by Executive Partners experience across 200+ completed placements. It stress-tests each of these dimensions to give you an honest picture of your true commercial position, before you start talking to banks.
How much of my AUM is actually portable?
Executive Partners observes that private bankers can overestimate portable AUM when total AUM and portable AUM are treated as the same number. The model tests how deep the personal client relationship runs versus the bank brand, wallet share concentration in the top relationships, the scope and enforceability of any non-solicit clause, and the compliance and documentation status of cross-border client files. The Portability Score below maps these and related dimensions in under ten minutes.
What is the average client retention rate when a private banker changes bank?
Executive Partners uses indicative model ranges informed by its placement experience. The current model range is 45 to 65 percent for UHNW books and 60 to 75 percent for HNW books. It uses an indicative 70 to 85 percent range for family-office relationships where the RM personally owns the primary client contact, and 20 to 40 percent for institutionally supported relationships. These are decision-support estimates, not observed averages or guarantees. Client decisions, contractual restrictions, onboarding and market events can materially change actual outcomes.
How do banks calculate AUM portability before making an offer?
Hiring banks run their own portability model before approving any senior RM offer. They will ask you to walk through your top 10 to 20 client relationships individually, not as an aggregate AUM figure. They want to understand relationship tenure, whether the introduction was personal or institutional, total client wealth and your wallet share, cross-border compliance status, and non-solicit exposure. The banks that move fastest on offers work with candidates who arrive with this analysis pre-built. The Portability Score produces exactly that, formatted for a hiring committee conversation.
