HDHP + Gimble Card

How Aetna PEO Companies Save 30-40% on Medical Insurance
Business Case | February 2026

The Opportunity

Companies on the Aetna PEO plan (a popular option through Rippling, Justworks, TriNet, and other PEOs) are overpaying for medical insurance. The low-deductible plan (LDHP 300/90) costs 39% more in premiums than the high-deductible alternative (HDHP 3300/90) while providing nearly identical actuarial value when out-of-pocket costs are factored in.

By switching to the HDHP and pairing it with Gimble Card, employers can give employees free healthcare (zero out-of-pocket costs) and still save hundreds of thousands of dollars per year.

The key insight: The premium savings from switching to the HDHP are so large that the employer can fund ALL employee out-of-pocket medical costs and still come out ahead. Every dollar of "coverage" on the LDHP is costing you $2+ in premiums.

What is Gimble Card?

Gimble Card is like Ramp for medical expenses. It provides employees first-dollar liquidity so they never face large, unexpected medical bills, even on a high-deductible plan.

1
Employee uses Gimble Card at doctor, pharmacy, or hospital
2
Gimble pays the provider immediately
3
Balance accumulates at 0% interest
4
Settled via HSA reimbursement or small payroll deductions

The result: employees experience $0 out-of-pocket costs at point of care. No surprise bills. No financial stress. Just swipe the Gimble Card.

The Employee Experience: Same Surgery, Three Plans

An employee needs a surgery in April that costs $4,800 after insurance. Here's the total monthly cost (premiums + out-of-pocket) under each approach:

Splitting the Savings

Switching to the HDHP generates significant premium savings. The question is: how do you and your employees share the benefit?

There are two paths, depending on whether you want a variable or fixed cost structure.

Path A: Variable Cost — Fund Employee OOP via Gimble Card

The employer funds some or all employee out-of-pocket costs through Gimble Card. This means employees pay $0 at the doctor, but the employer's total cost varies depending on how much healthcare employees actually use. The premium savings are so large that the employer saves money even in catastrophic scenarios.

The two scenarios below aren't choices — they're possible outcomes of the same approach:

Likely Outcome

~20% hit deductible, ~5% hit OOP max
$0
Employer saves
Employees pay $0

Worst Case Outcome

100% hit OOP max (extremely unlikely)
$0
Employer still saves
Employee OOP capped at LDHP level

In the worst case, the employer caps its OOP funding at the gap between HDHP and LDHP out-of-pocket maximums ($2,500/single, $5,000/family). The employee never pays more than they would have on the LDHP. Even in this catastrophic scenario — every employee maxing out — the employer still saves money because the premium gap exceeds the coverage gap at every tier.


Path B: Fixed Cost — HSA Seeding

If you prefer predictable budgeting, seed employee HSAs with a fixed amount ($2,000 single / $4,000 family). This gives employees tax-advantaged dollars to cover their out-of-pocket costs, and the employer's cost is known on day one.

Fixed Cost (HSA Seeding)

$2K single / $4K family — known cost, no variability
$0
Employer saves
Employees own their HSA forever

HSA funds are the employee's property — they roll over year to year, earn investment returns, and follow the employee if they leave. Unlike premium dollars that go to Aetna, this is real wealth employees keep. Healthy employees accumulate savings; those with medical needs use it for expenses.


Side-by-Side Comparison

Why This Works at Every Level

The math is straightforward: the premium gap between LDHP and HDHP is larger than the coverage gap.

Comparison Single (EE) Family (EF)
Annual premium savings (LDHP → HDHP) $4,353 $13,496
Max additional OOP exposure $2,500 $5,000
Net savings (even at max OOP) $1,853 $8,496

For every coverage tier, the premium savings exceed the maximum possible out-of-pocket costs. This is why the employer saves money in every scenario — even the catastrophic one where every employee maxes out. The HDHP is simply a better-priced product for the same underlying coverage.


Summary

Approach Employer Spend Employer Savings Per Employee OOP

All scenarios include Gimble fee of $40/employee/month.

Bottom line: The premium savings from switching to the HDHP are large enough to fund employee out-of-pocket costs entirely — and still save the employer money. The choice isn't whether to switch, it's how to share the benefit. Whether you choose variable OOP funding (Path A) or fixed HSA seeding (Path B), both employer and employees come out ahead.

Next Steps

  1. Review this analysis with your team and share employee counts for a custom quote
  2. Choose your approach: full OOP funding via Gimble Card, HSA seeding, or a hybrid
  3. Gimble handles the transition — enrollment, employee communications, card issuance
