A useful starting point is to model healthcare out-of-pocket costs as 5% to 10% of gross salary. Use the lower end for a single person with light medical use. Use the higher end for family coverage, recurring prescriptions, or care you already know is coming. Then compare that amount against take-home pay after state taxes and payroll deductions.
Build the comparison around one year
Do not split the decision into loose monthly pieces. Premiums come out of each paycheck, but deductible costs and copays show up in bursts. A role can look fine in one month and feel tight over a full year.
Start with these numbers:
- Base salary and any guaranteed bonus
- State and payroll taxes
- Employee premium for the plan you would actually enroll in
- Routine care such as office visits, labs, and prescriptions
- Deductible exposure and copays
- Employer HSA or FSA support, if the employer adds any
A simple annual formula keeps the comparison honest:
Usable yearly pay = salary - taxes - employee premium - expected care costs - expected deductible share + employer HSA/FSA support
That formula works because it keeps fixed costs and variable costs in the same year. A premium is a fixed hit. A deductible is a risk bucket. Routine care sits between the two.
Use three spending cases, not one
One estimate is too easy to distort. A better model uses three cases so you can see whether the salary gap still matters when healthcare changes.
| Scenario | What to include | What it tells you |
|---|---|---|
| Light-use year | Employee premium, preventive care, and only a few routine prescriptions | Shows whether the salary still holds up when you stay mostly healthy |
| Normal year | Premiums, office visits, labs, and typical prescription use | Gives the clearest everyday comparison for most workers |
| High-use year | Premiums plus deductible or out-of-pocket max exposure | Shows whether the offer still works when the year gets expensive |
Do not use the out-of-pocket max as your default annual spend unless you know you have planned care, ongoing specialty treatment, or a family pattern that regularly pushes costs up. For most people, the normal-year case is the best place to start.
Where state changes the math
The same salary can produce very different take-home pay once state withholding enters the picture. The distinction matters because the healthcare number sits on top of the tax number, not beside it.
A state with lower income taxes can still lose ground if the health plan is weaker, the premium is higher, or the deductible is far more aggressive. On the other hand, a slightly higher-tax state can still come out ahead if the plan has lower payroll deductions and lower expected care costs.
For remote roles, use the actual payroll and residency setup that applies to the job, not the office address in the offer letter. For workers near a border or splitting time between states, that detail can change the entire comparison.
Who should use the lower end of the range
The 5% side of the model usually fits people with limited care needs and simple coverage. That often includes:
- Single workers with light medical use
- People who mainly need preventive care and an occasional visit
- Offers with modest premiums and a plan that does not push much cost into the deductible
- Situations where the salary gap is large enough that healthcare does not swing the result
In those cases, premium cost and state taxes usually do most of the work. If the numbers are close after those two items, the remaining healthcare costs are often manageable.
Who should move toward the higher end
The 10% side is more realistic when healthcare use is already part of the year. That can mean:
- Family coverage
- Recurring prescriptions
- Specialist visits or regular follow-up care
- Planned surgery, pregnancy, or another known medical event
- A plan with a high deductible and limited employer support
Here, the premium alone is not the main story. A cheaper premium can hide a much larger annual bill once visits, labs, medication, or deductible spending are added.
A simple way to compare two offers
If you are choosing between two states or two jobs, run the same steps for each one:
- Estimate annual after-tax income.
- Subtract the yearly employee premium for the plan you would enroll in.
- Add expected care costs for a light year, normal year, and high-use year.
- Add any employer HSA contribution back in as part of compensation.
- Compare the leftover amount, not just the headline salary.
The better offer is usually the one that leaves more usable money after taxes, premiums, and expected care. A slightly lower salary can easily win if the healthcare side is lighter.
Common mistakes that distort the result
- Comparing gross salary only. Gross pay does not show what gets taken out before money reaches you.
- Counting premiums as the whole healthcare cost. Premiums are only one piece. Copays, prescriptions, and deductible exposure still matter.
- Using the deductible as the default annual spend. The deductible is a risk level, not an automatic bill every year.
- Ignoring employer HSA or FSA support. Employer money changes the real value of the offer.
- Forgetting the people on the plan. Family coverage, dependent care, and recurring medications change the math fast.
- Leaving your doctors out of the decision. A cheaper plan can be a poor fit if it pushes you toward different providers or harder access.
This is where a salary-by-state comparison goes wrong most often. The salary looks clean, but the year is not clean.
What to do when the offers are close
If the salary gap is small, do not overvalue the prettier headline number. Look at the plan that gives you:
- Lower fixed payroll deductions
- A deductible you can realistically handle
- Better support for regular prescriptions or visits
- Employer HSA support, if available
- Less chance of surprise bills during a bad month
When the final difference is modest, simplicity matters. The better choice is the one that leaves you with fewer cash-flow shocks over the year.
Practical verdict
Use salary by state as a net-pay comparison, not a gross-pay contest. Start with take-home pay, then subtract employee premiums and expected healthcare costs. A rough planning range of 5% to 10% of gross salary works well for many people, but the right number depends on how much care the household actually uses.
For light-use years, premium and tax differences usually decide the answer. For family coverage, recurring prescriptions, or planned care, the deductible, copays, and employer HSA support carry much more weight. If an offer looks better only before healthcare is counted, it is not the better offer.
FAQ
Should I use gross salary or take-home pay?
Use take-home pay. Gross salary is only the starting point. Taxes and employee premiums decide what you actually keep.
Do premiums count as healthcare cost?
Yes. Premiums are part of your healthcare burden because they reduce each paycheck before you see the money.
When should I use the out-of-pocket max?
Use it when you expect planned care, a high-use year, or a household pattern that regularly pushes spending up. For ordinary years, the deductible and routine care are usually the better planning tools.
Do employer HSA contributions matter?
Yes. Employer HSA support changes the real value of the offer because it offsets part of your healthcare cost and adds to compensation.
How often should I update the model?
Update it at open enrollment and after any major life change such as marriage, a new dependent, a move, a new prescription, or planned treatment.
What if the salary is higher but the plan is worse?
Run the full annual model. If the higher salary disappears after taxes, premiums, and expected care, the lower salary with the better plan may leave you ahead.
