So a bit under 5% per the rest of the numbers in that link.

I can't find the detailed breakdown for 2025, but in 2024, they took in $308bn in premiums and paid out $264bn in medical costs. So even ignoring all of the downstream and systemic problems caused by insurance existing as a for-profit entity, they're taking 14% off the top just to exist as a middle-man.
