Every renewal season asks HR to walk the same tightrope, but the rope keeps getting thinner. Finance wants costs contained. Employees want coverage that doesn't shrink. And 2027 is shaping up to test that balance harder than most.
The numbers tell the story. Aon projects employer healthcare costs will rise 9.5% in 2027 — the fourth straight year of near-double-digit increases — pushing average spending above $19,000 per employee. Mercer's early read is a little lower at 8.2%, but calls it the biggest jump since 2003. Either way, the direction is clear, and it's steep.
To manage it, employers are reaching for familiar levers. More than half (59%) told Mercer they plan cost-cutting changes to their health benefits for 2027, including plan-design changes like higher deductibles. About two-thirds of large employers expect to raise the employee share of premiums. Translation: many employees are going to open their first 2027 paycheck and notice something's different.
The strategy that most often gets floated in that environment — steering more people toward a High Deductible Health Plan (HDHP) — makes real financial sense. But it runs straight into a wall of employee fear. Here's how to get over that wall without sacrificing trust.
For a lot of employees, the logic is simple and hard to shake: "high deductible" means "high risk." They picture a medical emergency, a huge bill, and no cushion. So they do the understandable thing and stick with the pricier PPO that feels safer — even when it isn't the better deal for them.
Here's the reality that fear obscures: for many healthy employees, an HDHP paired with a Health Savings Account (HSA) — a tax-advantaged account you can only use with an HDHP — is one of the most mathematically sound financial decisions available to them. Lower premiums free up cash every paycheck. Preventive care is typically covered in full. And the HSA offers a rare triple tax advantage that can compound into meaningful long-term savings.
The problem isn't the plan. It's that this math is genuinely hard to communicate at scale. A town hall and a benefits guide can explain how an HDHP works, but they can't answer the one question the employee actually cares about: "What would this cost me?" Without that answer, fear wins, and people default to the expensive, familiar option.
One of the most effective ways to make a cost-effective health plan feel safe is to pair it with a safety net — and this is where voluntary benefits earn their keep.
Supplemental coverage such as accident, critical illness, and hospital indemnity acts as a financial shock absorber. If someone on an HDHP has an unexpected medical event, these benefits can help cover the out-of-pocket exposure, often for a modest monthly cost. Bundled thoughtfully, an HDHP plus supplemental coverage can protect the employee and save the employer money at the same time.
The catch is the same one we keep running into: employees won't adopt what they don't understand. Voluntary benefits are chronically underused — not because they lack value, but because that value only becomes obvious when you connect it to a real-life "what if." Framing matters as much as the offering.
You can't argue someone out of fear. But you can show them the math — and the math, made personal, is remarkably persuasive.
That's what smart choice architecture does. Instead of asking employees to imagine how a plan might perform, you show them how it would actually work for them, based on their real situation:
Scenario modeling on real claims. When employees can see their predicted out-of-pocket costs under each plan — informed by their own past healthcare use, not a generic average — the abstract becomes concrete. "High deductible" stops being scary when you can see that, for you, it costs less.
The full financial picture. Show the premium savings, the HSA tax advantages, and the long-term growth potential side by side. When people can see the whole equation, the HDHP often stops looking like a gamble and starts looking like the smart move it is.
The result is confidence, and confidence changes behavior. A 42,000-employee healthcare system used Nayya's personalized recommendations — which explained the value of each option for each employee's specific situation — to grow HDHP enrollment as part of a deliberate cost-saving strategy [insert verified HDHP adoption stat from the Nayya case study]. Employees weren't pushed; they were shown the math, and they chose.
You don't have to choose between containing costs and supporting your people. Those goals only conflict when the communication fails. When employees understand the math, the cost-effective choice and the employee-friendly choice are frequently the same choice.
That's the gap Nayya is built to bridge. By evaluating each employee's financial profile and health history, Nayya guides them toward the plan tier that fits their situation — explaining the "why" in plain language along the way. Employees make confident decisions, and both they and the company save money.
Rising costs will be part of the conversation for the foreseeable future. But the employers who navigate it best won't be the ones with the smallest increase — they'll be the ones whose employees trust that the decision was made thoughtfully, with their interests in mind. Show them the math, and you protect both the budget and the relationship.
