Carrier Rate Increases, Explained
Your Medigap benefits never change — a Plan G is a Plan G forever. So why does the premium keep going up? Here’s the honest, plain-English answer most agencies never give you — and exactly what to do about it.
The one thing to understand first
Medicare Supplement benefits are standardized by law — every insurer’s Plan G covers the exact same things. But insurers still set and raise their own prices. So a rate increase never means you’re getting less coverage; it means your carrier is charging more for the same coverage. That single fact is what puts you back in control.
Why premiums go up over time
Three forces push Medigap premiums higher. Understanding which ones apply to you is the difference between overpaying and staying ahead of it.
Medical inflation
Healthcare simply costs more each year. Every plan — no matter how it’s priced — reflects that rising cost over time.
Claims in the pool
Insurers price by how much the whole group of policyholders uses care. As a block of members ages and files more claims, premiums for that block rise.
Your age
On the most common pricing method, your premium climbs a little every birthday — and those age increases stack on top of inflation and claims.
The three ways carriers set your price
Every Medigap policy uses one of these three pricing methods. The coverage is identical — but how (and how fast) your premium rises depends entirely on which one you have.
Everyone pays the same
Age is never a factor — a 65-year-old and an 80-year-old pay the same base rate. It usually starts higher, but grows more slowly, and often becomes the better value the longer you hold it.
Locked to your age at purchase
Your premium is based on how old you were when you bought it — and it won’t rise just because you get older. It can still move with inflation and claims, but never for aging. Buying younger locks in a lower rate.
Based on your current age
The most common method nationwide. It’s often the cheapest at 65 — but the premium recalculates upward every birthday, and those increases pile on top of inflation and claims. The lowest price today can become the highest later.
The increases that catch people off guard
⚠ The “cheapest plan” can quietly become the priciest
An attained-age plan that looks like a bargain at 65 climbs every single year. Because age increases stack on top of inflation and claims adjustments, some people see two separate hikes in one year — one on their birthday, one at the plan’s annual change. Ten or fifteen years in, that “cheap” plan can cost more than the steadier options that looked expensive at first.
◆ The “closed block” trap
When a carrier stops selling a particular plan to new members, the existing group stops getting younger, healthier enrollees. Over time that closed group ages and files more claims — and premiums for everyone still in it can spike sharply. You may not even realize your plan has been closed to new business.
The catch: once you’re past your protected enrollment window, moving to a lower-priced carrier usually requires answering health questions. If your health has changed, you could be stuck — which is exactly why watching your rate before it spikes matters so much.
What to do when a rate increase hits
A rate-increase notice isn’t the end of the story — it’s your cue to act. Because benefits are standardized, you have real options.
Read the notice, not an ad
Compare your old and new premium, and note whether your policy is community, issue-age, or attained-age rated.
Compare the same plan letter
Your Plan G’s benefits are identical everywhere — so shop that exact plan across carriers to see who covers it for less.
Ask about discounts
Household, and other available discounts can quietly lower your rate without changing a thing about your coverage.
Don’t drop coverage blindly
Never cancel until new coverage is approved — and remember switching may involve health questions, so timing matters.
This is exactly where a lifelong advocate earns their keep.
Most people find out about a rate increase from a letter — and just pay it. We do it differently.
