Benefits are 20-30% of total comp and nobody prices them
I've sat across the table from dozens of candidates negotiating offers. Almost all of them anchor on base salary. Roughly 1 in 20 asks for the health premium contribution. Almost none compute the actual dollar value of the benefits package. The result: people routinely leave $15-30k of annual value on the floor by missing benefits gaps that would be cheap for employers to close.
A $135k base salary at Company A with $12k/yr of total benefits value is meaningfully less than $125k at Company B with $28k/yr of benefits value — even though Company A's headline number is higher. The gap compounds over a 4-year stay: $40-80k of missed total comp if you took Company A on the base alone.
This calculator puts a dollar sign on health coverage, retirement match, PTO, and "other" benefits so you can compare offers or re-evaluate your current job in total-comp terms. The specific numbers matter. A generic "benefits are worth 20-25% of base" is close to right on average but not right for your specific package.
How to source the numbers
Employer health contribution per month. Not what you pay — what the employer pays. This shows up on your benefits election page or offer letter. Typical ranges: $450-700/mo single coverage, $1,200-2,000/mo family coverage. The employee portion is usually a much smaller number ($100-300 single, $400-900 family) and is deducted from your paycheck pre-tax.
Retirement match per year. Your employer's actual contribution. If the match is "100% of the first 5% of salary" and you make $130k, the match is $6,500/yr (assuming you contribute at least 5%). Many employers also have profit-sharing or non-elective contributions (e.g., a flat 3% of salary added whether you contribute or not) — include those.
PTO days × your daily rate. PTO is compensation you can use — it's work you didn't do but got paid for. At $130k salary, one day is ~$500. 20 PTO days = $10,000 of value. This captures the "unlimited PTO" variance too: if you only actually take 12 days under unlimited, your PTO value is $6,000, not theoretical $10,000.
Other benefits per year. HSA/FSA employer contributions, wellness stipends, professional development budget, phone and internet stipends, tuition reimbursement, life insurance, short/long-term disability, commuter benefits, pet insurance, parental leave pay above baseline. Most people's "other" lands $2,000-6,000. If you don't know, ask HR for the benefits-summary page.
What benefits actually cost the employer vs. are worth to you
Employer-sponsored benefits have a peculiar property: they often cost the employer less than they're worth to you. Three examples:
- Health insurance. A large employer pays ~$550/mo for the equivalent of a $950/mo individual plan, because of group risk pooling. If you bought comparable coverage on the ACA marketplace, you'd pay the full $950. The tool measures the employer contribution, but your replacement cost is actually 1.5-2x that number.
- 401(k) match. An exact dollar-for-dollar match. No mystery there. But the tax-advantaged contribution space is hard to replicate outside an employer plan — so even though the match itself is $6,000, the optionality to save another $18,000+ pre-tax is additional implicit value.
- Parental leave. 12 weeks of paid leave on a $130k salary is $30,000 of comp paid when you're not producing output. Employers treat this as retention spending; to you, it's tax-free time with a new child and a guaranteed return to your role.
Net: the calculator's headline "total benefits value" is a floor. Your replacement cost for the same coverage on the open market is typically 30-70% higher than the employer-contribution number.
The PTO problem
PTO is the line item people most consistently mis-price. Two failures.
Failure 1: unused PTO. 55% of US workers don't use all their PTO. Average unused is 4-6 days. If your 20 days of PTO is really only 14 actual-used, your effective benefit value is 30% lower than the calculator shows. Take the PTO.
Failure 2: "unlimited PTO" averaging 13 days. Employers love this policy because it reduces accrual liability on the balance sheet and, in practice, most workers take less under unlimited than they did with defined days. If your offer is unlimited, use 12-16 days as the realistic number — not the 25 you might otherwise claim.
A useful exercise: look at your last 3 years of days taken. If you're chronically under-using, renegotiate: ask for a formal minimum ("take 25 days/year, no exceptions") rather than a larger unlimited bank. Some managers will agree; it aligns their interests with yours.
A real-world comparison
Two offers I worked through with a senior product manager last quarter.
Offer A. $155k base. $10k bonus target. $400/mo employer health contribution. 401(k) match of 4% of salary ($6,200). Unlimited PTO (she'd realistically take 15 days). $2,000 L&D budget. Annual headline comp: $165k + bonus. Annual benefits value: ($400 × 12) + $6,200 + (15 × $600 daily rate) + $2,000 = $22,000.
Offer B. $148k base. $15k bonus target. $850/mo employer health contribution. 401(k) match of 6% of salary ($8,880). 25 days defined PTO + 10 federal holidays. $3,000 L&D budget, $1,200 phone/internet stipend, $2,500 wellness stipend. Annual headline: $163k + bonus. Annual benefits value: ($850 × 12) + $8,880 + (25 × $570 daily rate) + $6,700 = $29,830.
Offer A looks $2k better on base + bonus. Offer B is $6k better on benefits. Net: Offer B wins by $4k/yr in total comp — and Offer B has the more-defined PTO policy, which she was likely to use more consistently. She took Offer B.
The benefit hierarchies by life stage
Benefit priorities shift as you age. A quick taxonomy:
- 22-28, single. Health insurance matters less (you're healthy), PTO matters a lot (first real time off in life), 401(k) match matters enormously because of compound horizon. Prioritize matches > PTO > flexibility > health.
- 28-38, partnered, maybe kids. Family health insurance becomes huge. Parental leave becomes huge. 401(k) still matters. PTO matters for kid care. Prioritize family health + parental leave > 401(k) > PTO > flexibility.
- 38-50, kids in school. Schedule flexibility often outweighs everything. Good health plan with low family deductible is critical. PTO for kid emergencies. Prioritize flexibility + health > PTO > retirement > other.
- 50+, career late stage. Retirement match becomes less about compound (short horizon) and more about immediate savings. Health insurance quality matters a lot (aging). PTO matters for caregiving or sabbatical planning. Prioritize retirement max + health > flexibility > PTO > other.
When comparing offers, weight the benefits categories by your life stage, not by total dollar value alone.
Negotiating benefits specifically
Benefits are often easier to move than base salary because they come from different HR budgets. Moves that sometimes work:
- Sign-on bonus equal to first-year 401(k) match waiting-period loss. If the new employer has a 6-month match eligibility wait, ask for a sign-on equal to the match you'd miss.
- Explicit PTO minimum in offer letter. Especially with unlimited PTO. "I'd like written confirmation that I'll take at least 20 days per year." HR almost always agrees because it's free to them.
- Extra professional development budget. $2,000 of L&D costs the company less than $2,000 of salary (no FICA on L&D reimbursement). Ask for more.
- Phone/internet stipend or home office stipend. $1,500/yr tax-free stipend is worth ~$2,200 of taxable comp. Easy to negotiate into a remote or hybrid role.
- Enhanced parental leave. For a role you'll be in through family planning, ask for the leave details in the offer letter. If they're below your target, ask for improvement — this is sometimes easier than getting $5k more in base.
If the base salary is stuck but the recruiter wants to close, benefits asks frequently get through where salary asks stall.
When benefits are bad and base is good
Some companies deliberately run lean benefits and compensate with higher base. Big-tech at the staff+ level is like this; small boutique consulting firms too. If you can self-insure (high savings rate, good alternative health coverage, your own IRA), the high-base / low-benefits model can work for you. You capture the comp in cash and spend it how you want.
Conversely, some traditional employers run rich benefits at lower base. Government, universities, large financial services, unionized workplaces. If you value stability and don't want to actively manage benefits (insurance, retirement, etc.), these can be better than they look.
The calculator makes the comparison clean. A $180k base with $10k of benefits is $190k total. A $140k base with $50k of benefits is $190k total. They net to the same number; the question is which form of value fits your life.
