Question

What was the approximate cost of a private health insurance plan, in 2018, for…
An individual in the us?

Answer 1

If you mean employer‑sponsored private coverage (the most common kind of private insurance in the U.S.), the Kaiser Family Foundation’s 2018 Employer Health Benefits Survey gives the average annual premium for single (individual) coverage as $6,896 — about $575 per month. Employers paid about $4,565 of that on average, and workers’ average share was $2,331 annually (about $194/month).

If you meant individually purchased (non‑group/Marketplace) plans, costs varied a lot by age, location and plan level; after premium tax credits many people paid much less. Tell me which market (employer vs. Marketplace/non‑group) and whether you want before‑ or after‑subsidy figures and I’ll pull the specific numbers.
