For employers comparing an HDHP vs. PPO in 2027, the decision involves more than premium cost. A high-deductible health plan (HDHP) generally trades lower premiums for higher employee deductibles and out-of-pocket exposure, while a traditional PPO typically has higher premiums but lower deductibles and more predictable costs when employees use care.
Neither approach is universally better. Employers should compare premium impact, employee out-of-pocket exposure, workforce demographics, HSA strategy, employee education, and how well each option fits the organization’s broader employee benefits strategy.
MetLife describes HDHPs as plans that generally have lower premiums and higher deductibles than traditional health plans. A traditional PPO typically carries higher premiums with a lower deductible and lower out-of-pocket maximum. MetLife also notes an important distinction: an HDHP can itself use a PPO provider network, so “HDHP” and “PPO” are not always mutually exclusive plan categories.
HDHP vs. PPO: Key Differences
The primary difference between an HDHP and a traditional lower-deductible PPO is how healthcare costs are divided between premiums and employee out-of-pocket spending.
Factor | HDHP | Traditional PPO |
Premiums | Generally lower | Generally higher |
Deductible | Higher | Generally lower |
Out-of-pocket exposure | Potentially higher before plan coverage applies | Generally lower |
HSA eligibility | May qualify when IRS requirements are met | Traditional lower-deductible PPO generally does not qualify |
Provider network | Can use a PPO network | Uses a PPO network |
Employee experience | Requires greater understanding of deductible and HSA mechanics | May feel more predictable when employees regularly use care |
Employer decision issue | Premium savings must be weighed against employee cost exposure | Higher premium cost must be weighed against lower employee exposure |
MetLife’s current comparison explains that HDHPs typically have lower monthly premiums but higher deductibles and out-of-pocket maximums than traditional PPO plans. Traditional PPOs generally reverse that relationship.
That distinction makes the employer’s decision less about determining which plan is “better” and more about determining who bears which costs, when those costs occur, and how effectively employees can navigate the plan.
Employer Premium Considerations
One reason employers consider an HDHP is premium cost.
HDHPs generally carry lower premiums than plans with lower deductibles. That can create an opportunity to reduce the amount spent on premiums or redirect part of the difference toward other elements of the benefits strategy.
MetLife similarly describes lower premiums as one of the primary characteristics of an HDHP.
But employers should avoid evaluating the plan on premium savings alone.
A lower employer premium does not make employee healthcare expenses disappear. Instead, more cost may be experienced by employees through the deductible and other out-of-pocket requirements when they seek non-preventive care.
Before changing plan design, employers should compare:
- total employer premium contribution;
- employee payroll contributions;
- deductible levels;
- coinsurance and copays;
- out-of-pocket maximums;
- prescription costs;
- employer HSA contributions, if any;
- expected plan utilization; and
- the financial impact on different employee populations.
The most useful comparison is therefore not simply:
“Which plan has the lower premium?”
It is:
“How does each option distribute healthcare costs between the organization and employees?”
Employee Out-of-Pocket Exposure
Employee out-of-pocket exposure is one of the most important considerations when evaluating an HDHP.
Under an HDHP, employees generally pay a higher deductible before the plan begins sharing the cost of many covered services. MetLife also notes that unexpected medical needs or frequent non-preventive care can result in higher out-of-pocket expenses than an employee anticipated.
A traditional PPO with a lower deductible may offer greater cost predictability for employees who use healthcare services frequently, although that typically comes with higher premiums.
Employers should consider how the difference may affect employees who:
- have chronic health conditions;
- use prescription medications regularly;
- expect ongoing specialist care;
- have planned procedures;
- cover dependents;
- have limited emergency savings; or
- anticipate relatively little healthcare use.
This is also where employee perception matters.
An employer may view the HDHP primarily through its lower premium. An employee facing a medical bill may experience the plan primarily through its deductible.
Neither perspective tells the entire story.
Employers considering a plan change should model multiple employee scenarios rather than relying only on averages.
For example:
Employee A: Low healthcare utilization, values lower payroll deductions, and contributes consistently to an HSA.
Employee B: Regular prescriptions and specialist visits, with significant expected healthcare utilization.
Employee C: Limited routine use but experiences an unexpected hospitalization during the year.
The financial experience can be very different for each employee under the same plan.
How an HSA Fits With an HDHP
A Health Savings Account (HSA) is a tax-advantaged account that eligible individuals can use for qualified healthcare expenses.
To contribute to an HSA, an employee must be enrolled in an HSA-eligible high-deductible health plan and satisfy applicable eligibility requirements. MetLife explains that HSAs can be used for eligible healthcare expenses and that unused balances can carry forward rather than automatically expiring at year-end.
An HSA can change how employees experience an HDHP because the account gives them a way to set aside money for current or future healthcare expenses.
Employers can also contribute to employees’ HSAs.
An employer contribution may help offset some of the financial exposure created by a higher deductible, although the appropriate contribution will depend on plan economics, employer budget, workforce needs, and applicable contribution limits.
ESI also provides guidance around HSAs and FSAs as part of its broader employee-benefits offering, including administration and support for employers evaluating health savings and spending account options.
Important HSA distinction
An HSA is not simply another employer-owned benefit account.
MetLife notes that the HSA is owned by the employee. The employer sponsors the qualifying HDHP and may facilitate pre-tax payroll contributions, but the HSA itself belongs to the employee.
That employee ownership is part of what distinguishes an HSA from some other healthcare spending arrangements.
Employees can generally retain eligible HSA balances from year to year and when changing employers, subject to applicable federal rules.
MetLife HSA example: separate the evidence from the general guidance
MetLife uses its own HSA experience to illustrate how employee education and account design can influence adoption and savings behavior.
Its current HSA materials report higher-than-industry-average enrollment and contributions among participants in its program and emphasize customized employee education, interactive planning tools, and ongoing communication. Those figures represent MetLife program data, not guaranteed outcomes for employers adopting an HDHP or HSA strategy.
The general takeaway is not that adding an HSA automatically produces a particular result.
It is that an HSA strategy depends partly on whether employees understand:
- how the account works;
- how much they can contribute;
- how employer contributions work;
- which expenses qualify;
- that unused balances can carry forward; and
- how the account fits with the higher deductible.
That makes education part of plan design—not something to address only after enrollment.
Education and Adoption
Switching employees from a traditional PPO to an HDHP without adequate education can create confusion even when the economics make sense for the organization.
Employees may focus immediately on the higher deductible without understanding:
- the premium difference;
- employer HSA contributions;
- tax advantages;
- preventive-care provisions;
- how to use HSA dollars;
- what happens to unused HSA funds; or
- their potential total annual cost under different healthcare scenarios.
MetLife specifically emphasizes employee understanding as important to maximizing the value of HSA benefits. Its HSA resources include education, planning tools, and communications intended to increase participation and help employees understand the financial value of the account.
For employers, this makes benefits administration and communication central to adoption.
An employee should not have to become a health-plan expert to understand which option fits their situation.
Employers can improve the decision process by providing side-by-side examples such as:
Employee question | Information to provide |
What comes out of my paycheck? | Employee premium contribution |
What do I pay before insurance contributes? | Deductible |
What is my maximum potential exposure? | Out-of-pocket maximum |
Does the employer contribute money? | Employer HSA contribution |
What happens if I do not use the HSA balance? | Rollover and ownership rules |
What happens when I need care? | Deductible, coinsurance, copay and network examples |
Which plan may fit different healthcare-use patterns? | Scenario-based comparisons |
Education should also occur before employees are required to make an election.
A rushed explanation during open enrollment can leave employees comparing only the most obvious numbers rather than total potential cost.
Which Factors Should Employers Compare?
Employers considering an HDHP, PPO, or dual-plan approach should evaluate both financial and employee-experience factors.
A neutral plan-design review can include:
Decision factor | What employers should evaluate |
Employer premiums | What does each option cost the organization? |
Employee premiums | What comes out of employees’ paychecks? |
Deductibles | How much must employees pay before applicable coverage begins? |
Out-of-pocket maximums | What is the employee’s maximum covered in-network exposure under plan terms? |
HSA eligibility | Does the HDHP satisfy applicable HSA requirements? |
Employer HSA funding | Will the employer contribute, and how much? |
Workforce demographics | How might different employee populations experience each option? |
Healthcare utilization | How frequently are employees and dependents likely to use care? |
Financial readiness | Can employees absorb higher point-of-care expenses? |
Provider access | Are important providers included in the applicable network? |
Education | Can employees understand the tradeoffs before enrollment? |
Administration | Can payroll and benefits systems support HSA contributions accurately? |
Adoption | How will the employer measure enrollment and employee response? |
Employers should also consider whether employees will have a meaningful choice.
Offering both an HDHP and a traditional PPO may allow employees to select based on their individual healthcare and financial circumstances, but offering multiple plans also increases communication and administrative complexity.
That tradeoff should be part of the review.
ESI’s employee benefits services include benefits planning and support designed around the needs of both the business and its workforce.
2027 HDHP vs. PPO Review Checklist
Before changing plan design, employers can ask:
- What is the employer premium difference between the options?
- What is the employee premium difference?
- How do deductibles compare?
- How do out-of-pocket maximums compare?
- What healthcare expenses are employees most likely to experience?
- Does the HDHP meet HSA eligibility requirements?
- Will the employer contribute to employees’ HSAs?
- How does that contribution affect the effective employee exposure?
- Can employees afford the higher deductible if significant care is needed early in the year?
- What do current utilization patterns suggest?
- Are employees familiar with HSAs?
- What education will employees receive before enrollment?
- Can payroll accurately administer employee and employer HSA contributions?
- Should employees have both an HDHP and PPO option?
- How will the organization evaluate adoption after implementation?
The objective is not to prove that an HDHP or PPO is the better design.
It is to understand the tradeoffs well enough to determine which structure—or combination of structures—best fits the employer and workforce.
Frequently Asked Questions
Is an HDHP Cheaper for Employers?
An HDHP generally has lower premiums than a traditional lower-deductible health plan, which may reduce employer premium costs. MetLife identifies lower premiums as a common characteristic of HDHPs.
However, employers should consider the complete design. Employer HSA contributions, contribution strategy, administration, and the desired level of employee financial protection can change the overall economics.
A lower premium therefore does not automatically mean the lowest total cost or best workforce fit.
What Is the Difference Between an HDHP and PPO?
An HDHP generally has a higher deductible and lower premium than a traditional lower-deductible PPO.
A PPO describes a provider-network structure, while HDHP refers primarily to a plan meeting defined deductible and out-of-pocket requirements. An HDHP can therefore operate using a PPO network. MetLife specifically notes this distinction in its HDHP-versus-PPO guidance.
How Does an HSA Work With an HDHP?
Employees who meet applicable eligibility requirements and are enrolled in an HSA-qualified HDHP can contribute to a Health Savings Account. Employers may also contribute.
HSA funds can be used for qualified healthcare expenses, and eligible unused balances can carry forward from year to year. The account is owned by the employee rather than the employer.
What Should Employers Consider Before Switching Plans?
Before switching to an HDHP or changing the plan mix, employers should compare premiums, deductibles, out-of-pocket maximums, HSA contributions, workforce healthcare needs, employee financial exposure, provider access, administration requirements, and employee education.
Employers should also model how different employees could experience the proposed change rather than evaluating the decision solely through average premium savings.
Schedule a 2027 Plan Design Review
Choosing between an HDHP and traditional PPO requires more than comparing premium quotes. ESI can help employers review their current employee benefits, plan costs, employee contribution strategy, HSA options, workforce considerations, and benefits administration needs before making 2027 plan-design decisions.
