Why did my health insurance premium increase? Common reasons include higher plan costs, a change in how your employer shares costs, or a new coverage election.
EMPLOYEE BENEFITS GUIDE · REVIEWED OCTOBER 21, 2026
A higher payroll deduction can reflect several factors, and it may not change by the same percentage as the employer’s overall health benefit costs.
Compare the coming year’s premium for the same plan and coverage tier. Then ask the benefits team which parts of the change apply to you.
The 2027 Employer Cost Outlook
Marsh’s September 2026 employer health-cost survey announcement reports preliminary responses from more than 1,800 U.S. employers. Respondents expected total health benefit cost per employee to rise an average of 8.2% in 2027 after planned cost-reduction measures.
That is an employer-cost forecast, not a required premium increase for every employee. It does not establish the renewal rate for your company or an ESI-related plan. Your own deduction can change by a different amount.
The announcement identifies pressures involving medical treatment costs and other factors, including weight-management GLP-1 medications. These broader findings do not identify the cause of any individual employer’s renewal.
Check Whether You Are Comparing the Same Coverage
Look at the plan option, employee-only or family tier, and enrolled dependents. A change in any of those can affect the deduction even if the rate for your previous election stayed the same.
Check whether each amount is monthly or per paycheck, and confirm the number of deductions. Amounts on different schedules are not directly comparable.
Ask whether the enrollment summary includes a surcharge, credit or adjustment. Review those entries separately from the underlying medical premium.
Ask About the Employer’s Contribution
The employer and employee share premium costs according to the employer’s program. If the employer contribution changes, your share can change even when the total plan cost moves by a different percentage.
Ask for the coming year’s employee rate and, where available, an explanation of the contribution structure. Focus on what you will pay for the option you are selecting.
If the employer also adds or changes HSA funding, include it in the overall benefits comparison. Keep account funding separate from the medical premium so you can see each clearly.
Calculate the Change in Dollars
For example, a deduction rising from $120 to $132 over 24 paychecks increases by $12 per paycheck, or $288 per year. That example is a 10% increase. These are illustrative amounts, not ESI rates.
Annual dollars help you understand the effect on your household budget. A percentage alone does not show how much money you will need for the new election.
If your payroll deduction differs from the final enrollment confirmation, contact the benefits team. Ask whether the difference reflects your election, the deduction schedule or a correction.
Review the Rest of the Plan Before Switching
Compare deductible, copays, coinsurance, network and prescription coverage as well as premium. HealthCare.gov’s total-cost guide explains why health plan choices should consider total annual costs.
An option with a lower premium can require more spending when you use care. A higher premium does not automatically mean every service or medication is covered.
Use the same household care assumptions to compare options. Estimate routine spending and a year with substantial covered care, and confirm whether your providers and medications fit the alternative.
Questions to Ask the Benefits Team
Ask: “Is this the new rate for the same plan and tier? Did the employer contribution change? Are surcharges, credits or payroll adjustments included? What other plan features changed at renewal?”
Request the current benefit summary and save the final election. Those records help you distinguish a planned increase from a possible deduction error.
Keep Renewal Communication Clear
Employees should use their employer’s actual renewal information to understand their own premium. Employers can explore ESI’s employee benefits services and ESI’s benefits renewal article for help communicating benefits choices.
A useful explanation separates the plan’s cost, the employer contribution and the employee’s payroll amount.
A PRACTICAL NEXT STEP
Your Renewal Checklist
- Compare the same plan, coverage tier and payroll schedule.
- Separate total plan cost from your employee contribution.
- Check dependents, surcharges, credits and plan design.
- Ask which changes apply to your election.
- Compare premium and coverage before switching.

Common Questions
Can my deduction rise if I did not file claims?
Yes. Premiums and payroll deductions can change for reasons beyond one employee’s claims, including renewal pricing, employer contributions or coverage tier.
Does a national cost forecast predict my own increase?
No. A survey forecast describes broader employer costs. Your employer’s rates and your payroll deduction may change by a different amount.
What does the 8.2% 2027 figure mean?
Marsh reported surveyed employers expected total health benefit cost per employee to rise an average of 8.2% in 2027 after planned measures. It is a forecast, not a rate for every employer or worker.
