If your 2027 Federal Employees Health Benefits (FEHB) premium changed by a very different percentage than your plan’s total premium, you are not misreading the rates. The government pays part of the premium under a formula that does not move in step with individual plan prices, so the enrollee’s share can rise or fall far faster than the total premium. One plan raised its total premium 43%, and its Self and Family enrollees’ share rose 84%. Another kept its total premium flat, and its High Option enrollees pay about 13% less.
The formula is predictable, and this article explains it with real examples from the Office of Personnel Management’s (OPM) 2027 files, including what a big drop in premium does and does not mean if you are thinking about switching plans.

How the government contribution works
Dollar figures in this article are biweekly premiums for Self and Family unless noted. Annuitants pay monthly, so OPM’s published monthly changes appear where they matter. Plan-by-plan rates are on the FEHB premium rates page.
For most employees and annuitants, the government pays the lesser of two amounts, according to OPM’s 2027 Open Season highlights:
- 72% of the program-wide weighted average premium for the enrollment type, or
- 75% of the total premium for the plan the enrollee selects.
The first amount is the same across plans for a given enrollment type, so it works as a dollar cap. The second amount moves with each plan’s own premium. Whichever is lower is what the government pays, and the enrollee pays the rest. These figures reflect the standard contribution for most employees and annuitants; some employees, including certain part-time employees, receive a different contribution.
The effect shows up even in the averages: OPM reports that FEHB total premiums rise 9.3% on average for 2027, while the enrollee share rises 10.9% on average. In OPM’s rate files, the maximum government contribution rose 8.4% for Self Only, 7.9% for Self Plus One, and 8.5% for Self and Family:
| Enrollment type | 2027 maximum government payment | Dollar increase from 2026 | Premium where the cap starts to apply, 2026 / 2027 |
|---|---|---|---|
| Self Only | $352.04 | +$27.28 | $433.01 / $469.39 |
| Self Plus One | $767.53 | +$56.36 | $948.23 / $1,023.37 |
| Self and Family | $843.82 | +$65.79 | $1,037.37 / $1,125.09 |
This article calls the premium in the last column the cap trigger price. It is the total premium at which the cap starts to apply, calculated by dividing the cap by 0.75. A plan priced at or below its cap trigger price is in the 75% zone, where the government pays 75% of the premium. A plan priced above it is in the capped zone, where the government pays the maximum dollar amount. The two zones behave differently:
- In the 75% zone, the enrollee pays 25 cents of every extra dollar the plan charges while the premium remains in that zone. If the plan stays in the 75% zone in both years, the enrollee’s percentage change matches the total premium’s percentage change, subject to rounding.
- In the capped zone, the enrollee pays every extra dollar the plan charges while the premium remains above the cap trigger price. The government’s payment changes when the annual cap changes.
The rule matches OPM’s data. Checked against every Self Only, Self Plus One, and Self and Family rate line in OPM’s 2027 premium charts, the government payment equals the lesser of the cap and 75% of the total premium, to within a cent. The same check holds for the prior-year payments reconstructed from OPM’s comparison columns where a 2026 comparison is available.
A rule of thumb for capped plans
For a plan that is capped in both years, the math is simple. The enrollee’s dollar change equals the plan’s dollar premium change minus the cap’s dollar increase. For Self and Family, the cap rose $65.79.
| Self and Family, biweekly | Total premium change | Subtract cap increase | Enrollee change | Enrollee percent change |
|---|---|---|---|---|
| Blue Cross and Blue Shield Standard Option | +$105.03 (+8.5%) | −$65.79 | +$39.24 | +8.6% |
| American Postal Workers Union (APWU) High Option | +$189.68 (+17.0%) | −$65.79 | +$123.89 | +36.7% |
| Special Agents Mutual Benefit Association (SAMBA) High Option | +$264.42 (+20.0%) | −$65.79 | +$198.63 | +36.5% |
Blue Cross and Blue Shield Standard Option raised its total premium 8.5%, nearly the same percentage as the cap increase, so enrollees saw a similar 8.6% increase. When a capped plan’s premium rises faster than the cap, the enrollee’s percentage increase is larger than the total premium’s percentage increase. The enrollee pays the remaining dollar increase from a smaller starting amount. A 17.0% total premium increase at APWU High Option became a 36.7% increase in the enrollee share.
Example 1: Mail Handlers Benefit Plan (MHBP) Standard Option crossed the cap trigger price
| Self and Family, biweekly | 2026 | 2027 | Change | Percent change |
|---|---|---|---|---|
| Total premium | $872.79 | $1,244.60 | +$371.81 | +42.6% |
| Government pays | $654.59 | $843.82 | +$189.23 | +28.9% |
| Enrollee pays | $218.20 | $400.78 | +$182.58 | +83.7% |
In 2026, MHBP Standard’s Self and Family total premium of $872.79 sat below the 2026 cap trigger price of approximately $1,037.37, so the government paid 75%, or $654.59. For 2027, the total premium rose 42.6% to $1,244.60, well above the 2027 cap trigger price of $1,125.09. Under a pure 75% rule, the government would pay $933.45. The cap holds it to $843.82, which leaves enrollees paying $89.63 more than a quarter of the total premium.
Of the $371.81 total premium increase, the government covered $189.23, or 51%, and the enrollee covered $182.58. The government’s share of the total premium fell from 75.0% to 67.8%. The enrollee’s percentage increase is roughly double the total premium’s percentage increase because enrollees started from only $218.20. The Self Only enrollee share rose 63.1% ($93.89 to $153.11), and Self Plus One rose 104.9% ($216.12 to $442.77).
For a Self and Family enrollee, that is about $4,747 more per year, or $395.59 more per month for an annuitant, according to OPM’s monthly rate comparison.
Example 2: Geisinger Standard, a real premium cut that looks bigger
| Self and Family, biweekly | 2026 | 2027 | Change | Percent change |
|---|---|---|---|---|
| Total premium | $1,298.01 | $1,144.10 | −$153.91 | −11.9% |
| Government pays | $778.03 | $843.82 | +$65.79 | +8.5% |
| Enrollee pays | $519.98 | $300.28 | −$219.70 | −42.3% |
Geisinger Health Plan Standard is available in its Pennsylvania service area and is capped in both years. The enrollee’s $219.70 decrease has two parts: the plan cut its total premium by $153.91, and the government’s cap rose $65.79. About 70% of the decrease comes from the lower total premium and about 30% comes from the higher cap.
The percentage looks dramatic because the government payment rises even as the total premium falls. The enrollee pays only the remainder, so an 11.9% total premium cut shows up as a 42.3% cut in the enrollee share. The government’s share of the total premium rose from 59.9% to 73.8%. The annual difference is about $5,712, or $476.03 per month for an annuitant, using OPM’s monthly rate comparison.
Geisinger Basic shows a related effect. Its total premium fell 11.2% to $1,097.93, which drops below the 2027 cap trigger price, so the government now pays 75% ($823.45) instead of the cap.
Example 3: Government Employees Health Association (GEHA), flat premiums and two different outcomes
Four GEHA options kept their 2026 total premiums. The table shows what happened to each for Self and Family.
| GEHA option | Total premium (both years) | Government pays, 2026 | Government pays, 2027 | Enrollee pays, 2026 | Enrollee pays, 2027 | Enrollee change |
|---|---|---|---|---|---|---|
| High Option | $1,303.21 | $778.03 | $843.82 | $525.18 | $459.39 | −$65.79 |
| Standard Option | $925.79 | $694.34 | $694.34 | $231.45 | $231.45 | $0.00 |
| High deductible health plan (HDHP) | $862.51 | $646.88 | $646.88 | $215.63 | $215.63 | $0.00 |
| Elevate Option | $915.42 | $686.57 | $686.57 | $228.85 | $228.85 | $0.00 |
High Option’s total premium of $1,303.21 is above the cap trigger price in both years, so the government pays the cap. The cap rose $65.79, and with the total premium unchanged, the enrollee share fell by exactly that amount, or 12.5% for Self and Family. Self Only fell 14.0% ($195.29 to $168.01), and Self Plus One fell 13.0% ($432.95 to $376.59). A Self and Family enrollee saves about $1,711 a year, or $142.55 per month as an annuitant. The decrease came entirely from the higher government contribution cap; GEHA High’s total premium was unchanged.
The Standard Option, HDHP, and Elevate Option are priced below their respective cap trigger prices in both years, so the government pays 75% of the total premium. With total premiums unchanged, neither the government payment nor the enrollee share changes. The higher cap does not affect those options because their government payments remain below it.
GEHA’s Elevate Plus Option tells the opposite story. Its total premium rose 16.0% and it remained capped, so the Self and Family enrollee share rose 27.8%, from $496.12 to $634.19.
When a big decrease comes from the formula, not a lower total premium
Every Self and Family option that remained capped in both years received the same $65.79 increase in the government contribution. For a capped option that held its total premium flat, like GEHA High, the full increase reduces the enrollee share. For a capped option that cut its total premium, like Geisinger Standard, the enrollee benefits from both changes. Panama Canal Area Benefit Plan shows the effect at a smaller scale: its total premium fell $46.48 (3.5%), and the enrollee share fell $112.27 (20.4%).
Because two capped options receive the same government contribution for the same enrollment type, the gap between their enrollee premiums equals the gap between their total premiums. In 2026, GEHA High Option cost a Self and Family enrollee $67.52 more than Blue Cross and Blue Shield Standard Option. In 2027, it costs $37.51 less. That $105.03 swing equals the Blue Cross total premium increase. The cap increase lowered both options’ enrollee costs by the same amount relative to what they otherwise would have been; the change in their ranking came from Blue Cross raising its total premium while GEHA held its total premium flat.
For someone deciding whether to switch, that leads to a few practical points:
- Compare 2027 dollar premiums side by side. Percentage changes depend on last year’s starting point and say little about which plan costs less now.
- A plan with a large decrease is not necessarily cheaper than its rivals. If both options remained capped, the cap increase benefits both equally.
- If an option remained in the 75% zone in both years, its enrollee premium changes in proportion to its total premium. The cap increase does not affect its payment.
- Premium is not total cost. Deductibles, copayments, provider networks, and prescription coverage can outweigh a few hundred dollars in annual premium. Review the 2027 brochures and comparison tools when available; the FEHB plan comparison page provides resources for that review.
How close each fee-for-service plan is to the cap trigger price
A plan’s distance from the cap trigger price shows whether the government pays 75% of its total premium or the maximum dollar contribution. If the cap stays fixed, a premium increase that carries a plan above that threshold leaves the enrollee paying every additional dollar above it. Crossing the threshold does not cause a sudden jump in the entire enrollee premium; it changes how additional premium dollars are divided. The cap itself is recalculated each year, so proximity to the 2027 threshold does not predict a plan’s position in 2028.
The table shows the 17 fee-for-service plan options in OPM’s 2027 rate file for Self and Family, ordered from highest to lowest total premium. Some have enrollment restrictions, so the list does not mean every option is available to every reader. Ten are above the $1,125.09 cap trigger price and seven are below it. SAMBA Standard Option sits just $2.45 below it.
| Plan option | 2027 total premium | Distance from $1,125.09 | Zone |
|---|---|---|---|
| SAMBA, High Option | $1,586.50 | $461.41 above | Capped |
| GEHA Elevate Plus Option | $1,478.01 | $352.92 above | Capped |
| Blue Cross and Blue Shield, Standard Option | $1,340.72 | $215.63 above | Capped |
| APWU Health Plan, High Option | $1,305.43 | $180.34 above | Capped |
| GEHA, High Option | $1,303.21 | $178.12 above | Capped |
| Panama Canal Area Benefit Plan, fee-for-service with point-of-service option | $1,281.60 | $156.51 above | Capped |
| MHBP, Standard Option | $1,244.60 | $119.51 above | Capped |
| Blue Cross and Blue Shield, Basic Option | $1,231.36 | $106.27 above | Capped |
| Foreign Service Benefit Plan, High Option | $1,226.47 | $101.38 above | Capped |
| Compass Rose Health Plan, High Option | $1,204.85 | $79.76 above | Capped |
| SAMBA, Standard Option | $1,122.64 | $2.45 below | 75% zone |
| APWU Health Plan, Consumer Driven Option | $973.35 | $151.74 below | 75% zone |
| GEHA, Standard Option | $925.79 | $199.30 below | 75% zone |
| GEHA Elevate Option | $915.42 | $209.67 below | 75% zone |
| GEHA, HDHP | $862.51 | $262.58 below | 75% zone |
| Blue Cross and Blue Shield, FEP Blue Focus | $701.42 | $423.67 below | 75% zone |
| Compass Rose Health Plan, Standard Option | $662.78 | $462.31 below | 75% zone |
A plan can sit in different zones for different enrollment types. SAMBA Standard Option is in the 75% zone for Self and Family ($1,122.64), but it is above the cap trigger price for Self Only ($487.91 against $469.39) and for Self Plus One ($1,032.17 against $1,023.37). Check the cap trigger price for the enrollment type you hold.
Across all 435 Self and Family rate lines in OPM’s fee-for-service and regional health maintenance organization (HMO) premium files, 237 are above the cap trigger price and 198 are below it. These are rate lines, not distinct plan options; regional HMO options can appear on multiple lines for different locations.
Checking your own plan before Open Season
- Find your plan and enrollment type on the FEHB premium rates page and note the total premium, not just the enrollee share.
- Compare the 2027 total premium with the 2027 cap trigger price: $469.39 for Self Only, $1,023.37 for Self Plus One, or $1,125.09 for Self and Family.
- For the prior-year comparison, use the 2026 cap trigger price: approximately $433.01 for Self Only, $948.23 for Self Plus One, or $1,037.37 for Self and Family.
- If the total premium exceeded that year’s cap trigger price in both 2026 and 2027, the enrollee’s biweekly change equals the plan’s dollar premium change minus the cap increase: $27.28 for Self Only, $56.36 for Self Plus One, or $65.79 for Self and Family.
- If the total premium was below that year’s cap trigger price in both years, the enrollee pays 25% of the total premium change, subject to rounding.
- If the option crossed the cap trigger price, as MHBP Standard did, compare the government’s payments directly. The enrollee’s change is the total premium change minus the change in the government’s payment.
- Compare 2027 enrollee premiums for the options you are eligible to join, then weigh coverage and out-of-pocket costs.
