How to calculate the true cost of an au pair

The short version

The true annual cost has five lines: (weekly stipend × 52) + agency program fee + education allowance + (extra living costs × 12) + one-time costs. On a minimum-stipend budget that totals roughly $25,000 a year — $478 a week, more than double the quoted stipend. The stipend is the line everyone advertises; the agency fee and the cost of hosting another adult are the lines nobody advertises.

Slice 1: the weekly stipend

The stipend is set by the U.S. Department of State's formula: the federal minimum wage ($7.25) × 45 hours, minus a 40% credit for room and board = $195.75/week. EduCare — the part-time track capped at 30 hours — uses the same formula at 75%, giving $146.81/week. These are floors, not fixed prices: agencies may set higher minimums, and families in expensive metros commonly pay $250–$300 a week to stay competitive during matching. You may always pay more; you may never pay less.

Slice 2: the agency program fee

This is the biggest surprise on the bill — typically $9,000–$12,500 a year. It covers recruiting and vetting, the matching process, background checks, the Form DS-2019 visa paperwork, and international airfare to the U.S. (domestic travel from the training academy to your home is sometimes billed separately). Most agencies offer payment plans over 4–6 months, which usually add a few hundred dollars to the total. It is a genuine annual cost, not a one-time signup fee — a fresh placement carries the full fee every year.

Slices 3–5: education, living costs, and one-time costs

The program requires host families to contribute up to $500 toward the au pair's coursework ($1,000 on EduCare). Then come the costs that feel invisible because they hide inside existing bills: extra groceries and utilities for another adult, the cell-phone line she needs for emergencies and GPS, the car insurance and gas if she drives, and family-vacation costs if she comes along — typically $300–$450 a month all in. Finally the one-time setup: the $35 SEVIS fee, arrival travel, the phone itself, and bedroom setup — budget around $500.

The worked example

The flat-rate effect: why the math improves with more children

Here is the insight that decides most au-pair comparisons: an au pair costs the same whether you have one child or four, while daycare and nannies price per child. Divide the $24,879 example across two children and the effective cost is $239 a week per child — against daycare at $1,500 a month per child, the au pair saves about $927 a month. With one child, the flat rate usually loses to per-child pricing; at two or more, it starts winning, and every additional child widens the gap.

The overtime ban (read this before a busy week)

Federal J-1 rules prohibit au pair overtime entirely — not at time-and-a-half, not with extra pay, not even if the au pair asks. An au pair may not be scheduled for extra childcare hours to earn extra money, may not take outside employment, and unused hours cannot be banked into a future week. The cap is 45 hours a week and 10 hours a day (30 hours a week on EduCare). Overlooked by most families: overnights count as working hours whenever the au pair is responsible for the children, even if everyone is asleep. For genuinely busy weeks, the legal answer is backup care — a sitter, a drop-in center, or an employer backup-care program — not extra au pair hours.

The second-year discount

Keeping the same au pair for a second year is substantially cheaper than a fresh placement. Both sides confirm an extension with the agency — the au pair must show completed coursework and monthly counselor contact — and the extension program fee runs far below a first-year placement. Host families who publish their breakdowns show year-one agency costs near $8,860 falling to about $6,857 on extension, before the stipend. It is the strongest argument for matching carefully the first time.

The tax picture, briefly

Three things to know: the stipend for care that lets you work generally qualifies for the Child and Dependent Care Tax Credit and your employer's Dependent Care FSA — but many FSA administrators treat agency placement fees as ineligible, so check your plan. And the program has one genuine structural tax advantage: au pairs on J-1 visas are typically nonresident aliens exempt from Social Security and Medicare taxes, so you owe no FICA share the way you would with a nanny. Confirm the details with a tax advisor; the rules have state-level wrinkles, especially in California and Massachusetts.
