Comparing Health Insurance Between Job Offers

TL;DR / Quick Take

Two offers with the same base salary can differ by $8,000–$12,000 a year in health costs alone once you factor in premiums, deductibles, and whether the employer covers dependents.

Premium, Deductible, or Employer Share — Pick Your Pain

Health plans come in three flavors that matter for offer comparison: what you pay per paycheck (premium), what you pay before insurance kicks in (deductible), and what your employer subsidizes.

A low-premium plan with a $5,000 deductible looks cheap until you need care. A high-premium plan with a $500 deductible costs more every month but protects you from surprise bills. For offer math, estimate your expected annual usage — not just the sticker premium.

Family Coverage: Where Offers Diverge Most

Single coverage differences are often a few hundred dollars a month. Add a spouse and two kids and the gap explodes. One employer might cover 90% of family premiums; another might cover 60%. On a $1,800/month family plan, that's $648/month — $7,776 per year — before anyone visits a doctor.

If you're comparing offers and you have dependents, ask HR for the exact family premium split, not just the employee-only rate on the benefits summary.

Frequently Asked Questions

Should I pick the plan with the lowest premium?

Only if you're healthy, rarely use care, and have an emergency fund to cover the deductible. Otherwise, total expected cost (premium + likely out-of-pocket) is the better comparison metric.

When do benefits start after I join?

Many employers start coverage the first of the month after your start date; some have a 30- or 60-day waiting period. A gap in coverage has a real cost — factor it in if you're leaving a job mid-year.

How do I put a dollar value on health benefits for Adjusted Value?

Use employer premium contributions plus any HSA seed money as a positive adjustment. Subtract your expected out-of-pocket (premium + deductible usage) as a negative. WMO models employer-paid premium share as a direct benefits value add.
