YSK how your employee health insurance premiums are split between your employer and yourself.

The premium is how much is paid for the insurance policy. With an employee plan the percentage paid by the employer is usually 60 to 100%. The rest is paid by you from your wages (aka salary for a lot of people). So if your premium was $10,000 for the year and your employer covered 80% then you'd see $2,000 removed from wages. (Your employer is thus covering $8,000).

This can be somewhat important when looking at how much you actually make if an employer is say only contributing near the minimum. This percentage differs based on the company and if it's a single or family policy.
