Why did my health insurance go up? For 2027 the answer is that care costs more and insurers and employers are passing it on: employers expect the biggest jump in benefit costs since 2003, and marketplace insurers proposed a median rise of 15%. You cannot stop the increase. You can find out what it takes from each paycheck before January and plan around the smaller one.
Why is health insurance going up in 2027?
Two surveys tell most of the story. Mercer's survey of employers, published 31 August 2026, expects the total cost of health benefits per employee to rise 8.2% on average in 2027. That is after employers cut what they can. Left alone, their current plans would cost 11% more.
On the marketplace, KFF's analysis of 276 insurers' filings found a median proposed premium increase of 15% for 2027. Insurers point to higher prices for care, specialty drugs and a sicker pool of customers. The enhanced premium tax credits ended on 31 December 2025, healthier people dropped their coverage, and the people left cost more to insure.
None of that is something a household can negotiate. What a household can control is the plan it picks and the budget it builds around the new price.
How a higher premium shows up on your paycheck
If you are insured through work, your share of the premium comes out of every paycheck as a deduction. When the premium rises, the deduction rises, and your take-home pay falls by the difference.
Employers are not absorbing all of it. Mercer found that 59% of employers plan cost cutting changes for 2027, such as higher deductibles, and about two thirds of large employers expect to raise the employee's share of the premium. So your deduction can rise faster than the 8.2% headline.
Here is an illustration, not a quote. Say your share is $200 a paycheck on biweekly pay and it rises 10%. That is $20 less in every paycheck, or $520 over 26 paychecks. Most workplace premiums are taken before tax, so the drop in take-home pay is usually a little smaller than the rise in the premium, but it is still a drop.
It lands in the first paycheck of January, which is already a thin month after the holidays. The general reasons net pay moves are in gross vs net pay.
What to check during open enrollment
Open enrollment is the one window each year when you can change plans without a life event. Your employer sets its own dates, usually a few weeks in the fall. Do not let last year's plan roll over unread.
Benefits materials usually show each plan's deduction per pay period. That is the number your budget needs, not the annual premium.
A cheaper premium with a much higher deductible can cost more in a year you actually need care.
Adding a spouse or children changes the tier, and the tier changes the deduction more than anything else.
It is also taken per paycheck. Set it on purpose, because it reduces take-home pay too.
A plan that drops your doctor from its network is not cheaper in practice.
How to budget for higher health insurance from January
Once you have picked a plan, work out the new take-home pay before the first paycheck arrives. Your employer's enrollment summary or your first January pay stub shows it. Then rebuild the plan around that number, not the old one.
Your bills do not shrink in January because your paycheck did. Rent, the car, utilities and card payments are the same size, so the cut comes out of whatever was left after them. Decide now where the $20, or whatever your number is, comes from: a smaller grocery line, a subscription you stop, or a slower savings transfer.
If your plan runs on the calendar year, the deductible also resets on 1 January. A doctor visit in January can cost more than the same visit in November. Hold a little back for that in the first pay periods of the year.
January is already squeezed by the holidays. Spreading the holiday spending across the paychecks before it, as in how to plan a Christmas budget, leaves more room for the new deduction.
If you buy your own plan on the marketplace
Open enrollment on HealthCare.gov runs from 1 November 2026 to 15 January 2027. In most states you need to choose a plan by 15 December for coverage that starts on 1 January.
If you get a premium tax credit, what you pay depends on the credit as well as the premium. Update your expected income for 2027 on your application, compare plans again rather than renewing automatically, and check what your monthly payment will be after the credit. KFF's tracker explains how much and why marketplace premiums are rising.
A marketplace premium is a bill rather than a deduction. Put it on the day it is due, so you know which paycheck pays it.
Doing this in Cashrou
Cashrou plans each pay period on its own, starting from the income that lands on that payday. When your take-home pay changes in January, change the income amount once, and the pay periods ahead are planned on what will really arrive.
The payday routine then shows what is left between now and your next payday after the bills still to come, with a buffer you set held back first. If the smaller paycheck no longer covers everything due before the next one, you see it on that payday, not at the end of the month.
A marketplace premium goes in as a bill on its due date, so it lands in the pay period that pays it. It works on weekly, every other week, twice-monthly and monthly pay. If you are paid every two weeks, how to budget a biweekly paycheck explains the calendar behind it.
