No. The official family FAQ lists both an additional US$15,000 DHS processing fee and a US$1 million gift for each included family member.
Build the household total carefully
Confirm current charges before relying on a calculation, and distinguish those amounts from medical, visa-related and professional expenses. Identify who will pay each line. Keep any relative whose eligibility is unresolved visible in the plan, rather than quietly budgeting as though that person is included.
Build the total from the person-by-person list rather than by applying a multiplier to the principal's figure, since charges are frequently set differently for the principal and for each accompanying family member and a package price may not be a simple multiple of either. Take each amount from current official materials and record where it was found and when. Then add the costs that attach to individuals rather than to the application: civil document retrieval for people born abroad, certified translations, any medical or biometric requirements, travel, and professional fees which may or may not be charged per person.
Note which amounts are payable at the outset and which later, and which are refundable if someone withdraws. A household total assembled this way can be revised when the list changes; one assembled from a headline figure cannot.
