In California (and pretty sure this is standard across the USA), unemployment insurance is paid by the employer so doesn't come out of your compensation.

The calculator I used also included payments for social security and medicare contributions, which you would use if you eventually fell below security security income bracket (knock on wood) or if you need medical as a senior (I believe age 65+)

For other health coverage, that is paid for by the employer so also wouldn't come out of your compensation.
