Personal Assistant Cost for High-Net-Worth Families

A personal assistant supporting a high-net-worth family commands a base salary of $120,000 to $250,000 in the US, according to Morgan & Mallet’s 2025/26 Household Staff Salaries Annual Report — but the salary line understates what the household actually writes off. Layer in employer payroll taxes, workers’ compensation, health contributions, and an amortized placement fee, and the true annual outlay runs roughly 19 to 22 percent above the salary figure.

That gap is the entire story. Most coverage of personal assistant compensation quotes a salary band and stops. The numbers below trace every cost component to a named source, calculate the all-in figure, and convert it into a single multiplier any household can apply to its own offer.

What “personal assistant” actually means at this income level

The title spans a wide band, and the salary follows the scope. At the entry of the private-market range, a personal assistant handling scheduling, correspondence, travel logistics, and vendor coordination for a single principal runs $85,000 to $145,000 depending on metro, per Riveter Consulting’s 2025 market breakdown, which reports Los Angeles roles at $85,000–$140,000 and New York at $90,000–$145,000.

Higher up, the role merges with operations. Morgan & Mallet reports US personal assistant salaries reaching $300,000 for assistants managing exotic car fleets, private aviation logistics, and staff across multiple residences. Findcelebrityjobs.com places the elite UHNW-and-celebrity tier at $150,000 to $250,000-plus, noting these candidates typically carry five to ten years of experience and overlap heavily with executive assistant skill sets. When the job description starts to include supervising other staff and running multiple properties, the comparison is no longer a personal assistant — it is approaching an estate manager role and its pay scale.

For a useful benchmark on the labor market beneath this premium tier, BLS Occupational Employment and Wage Statistics (May 2023) put the mean annual wage for Executive Secretaries and Executive Administrative Assistants at $73,680, with the 90th percentile at $104,000. The private-employer premium over that public figure — roughly $50,000 to $150,000 at the top — is the price of discretion, availability, and the absence of a corporate HR buffer between principal and staff.

Building the all-in cost

Salary is the starting line. Six additional cost components sit on top, and each has a named source rather than a rule of thumb.

Employer FICA. The household owes 7.65% — 6.2% Social Security plus 1.45% Medicare — on wages, matching the employee’s share. IRS Publication 926 sets the 2026 Social Security wage base at $184,500, so salaries above that cap stop accruing the 6.2% portion while Medicare’s 1.45% continues uncapped. On a $150,000 salary, employer FICA runs $11,475. On a $200,000 salary, the Social Security portion caps out and the employer owes $14,339 rather than the $15,300 a flat 7.65% would imply.

Federal unemployment tax (FUTA). The Federal Unemployment Tax Act levies 6% on the first $7,000 of wages, but IRS Publication 926 confirms a state credit of up to 5.4%, dropping the effective rate to 0.6% — a flat $42 per employee for any full-time salary at this level. Small in dollar terms, but it is a hard obligation, and the credit requires timely state unemployment contributions to claim.

State unemployment tax (SUTA). The State Unemployment Tax Act rate and wage base vary by state. New employer rates commonly fall in the 2–4% range on a state-specific wage base. The model below uses a representative $189 (roughly 2.7% on a $7,000 base) and flags it as an estimate; a household should pull its own state’s new-employer rate.

Workers’ compensation insurance. Required for household employees in many states, priced per $100 of payroll by job classification. Clerical and personal-assistant classifications carry low rates — typically under 1% of payroll — though live-in or driving duties can raise the classification. The model assumes roughly 1%, an area covered in depth in the workers comp cost guide for household employees.

Health and benefits. The largest non-salary line. UHNW packages routinely include health insurance, paid leave, and often a 401(k) match; the model uses a $6,000–$8,400 employer health contribution scaled to role tier. Households building broader packages should consult the health insurance cost for household staff for plan-level detail.

Amortized placement fee. Domestic staffing agencies charge 20–30% of first-year salary, with 25% the common midpoint, per published fee schedules from agencies including Muffetta (16–30%) and Deb’s Domestic Agency (25%). Retained searches for UHNW placements often sit at the top of that band. Amortized over an expected four-year tenure, a 25% fee on a $150,000 salary adds roughly $9,375 per year — and the real exposure is turnover, the subject of the recruiting and turnover cost analysis.

Total cost by salary tier

The table below runs the full calculation across three representative salary points. Every figure is annual.

SUTA and workers’ compensation are representative estimates and vary by state. Calculations and Finluxy Staff True Cost Multiplier by Finluxy.

The Finluxy Staff True Cost Multiplier

The Finluxy Staff True Cost Multiplier is total annual employment cost divided by gross salary — a single number showing how much more than salary the household pays. Across the three tiers it lands between 1.19× and 1.21×, meaning a household pays 19 to 21 percent above salary in fully loaded cost.

One feature of this multiplier deserves attention: it falls as salary rises. That runs against intuition. The reason is structural. FUTA is a flat $42 regardless of salary, SUTA is effectively flat, and the Social Security portion of FICA stops at the $184,500 wage base — so the percentage drag of these fixed and capped costs shrinks as the denominator grows. At $95,000 the multiplier is 1.21×; at $200,000 it has slipped to 1.19× despite a larger absolute spend. The household pays more in dollars and a slightly smaller proportion in overhead.

What most coverage misses

Published personal assistant salary guides almost universally quote the band and call it the cost. The overlooked figure in this dataset is the placement fee’s weight relative to payroll taxes. At the $150,000 tier, the amortized placement fee ($9,375/year) is itself roughly 80% the size of the entire employer FICA bill ($11,475) — and it scales with turnover, not time. A household that churns through two assistants in four years effectively pays the placement fee twice, pushing the multiplier from 1.20× toward 1.26× or higher. Payroll taxes are predictable; the placement line is the one a household can actually move, and it moves through retention, not negotiation. For comparison shoppers weighing the full picture, the household staff cost guide for affluent homes places the personal assistant line against every other role.

Live-in arrangements change the math

Some personal assistant roles are live-in, particularly in multi-residence households where the assistant travels with the principal. Morgan & Mallet notes live-in roles carry lower base salaries but include accommodation and meals worth $20,000 to $40,000 a year. IRS Publication 926 requires the value of lodging to be evaluated for inclusion in compensation in certain circumstances, which affects the taxable wage figure and therefore the FICA base.

The trade-off is rarely a clean wash. A $40,000 room-and-board value offsetting a $30,000 salary reduction leaves the household ahead on cash but exposed on the housing cost it was already carrying, and the IRS treatment is fact-specific. The full comparison — cash salary, imputed lodging value, tax treatment, and opportunity cost of the space — is laid out in the live-in vs live-out total cost comparison.

Methodology

What this means for a $150k+ household

For a household in the $150k+ income band considering a personal assistant, the decision threshold is not the salary — it is the fully loaded cost against the value of the principal’s reclaimed time. A $150,000 salary is a $179,781 annual commitment at a 1.20× multiplier, and that figure is structural, not negotiable: the payroll taxes and minimum insurance are fixed by law. The levers a household actually controls are scope, tenure, and placement strategy. A tightly scoped live-out role at the $95,000 tier carries the same multiplier as the $200,000 role but less than half the absolute cost, and the single largest variable expense — the placement fee — rewards retention more than any negotiation at hire. Households running multiple staff should model the combined number rather than role-by-role; the interaction of payroll thresholds and benefits across a full team is the subject of the combined household staff payroll math. The figure to anchor on is not what the assistant earns, but what the household clears after the multiplier — and whether the hours that buys back are worth more deployed elsewhere.
