How much does Medigap insurance cost in 2026?

Medigap premiums in 2026 vary by plan letter, age, gender, tobacco use, and carrier. In New Jersey, monthly rates for Plan G typically range from around $130 at age 65 to $300+ at age 80. Rates vary by carrier, so comparing quotes from multiple companies is essential.

Why does the same Medigap plan cost different amounts from different carriers?

Medigap plans are standardized by law, meaning Plan G from one carrier covers exactly the same benefits as Plan G from another. The difference is pricing methodology, claims history within each carrier's insured pool, and how aggressively a company prices to attract new members. Long-term rate stability matters more than starting price.

Can I switch Medigap plans if my rates go up?

You can apply to switch carriers anytime, but outside your initial 6-month Medigap Open Enrollment Period, carriers can medically underwrite you. If you have health conditions, you could be denied. That's why choosing a carrier with stable long-term pricing from the start is so valuable.

What's the difference between attained-age and community-rated Medigap pricing?

Attained-age plans increase your premium as you get older, on top of any general rate increases. Community-rated plans charge the same base rate regardless of age. Community-rated plans often start higher but can cost less over time. New Jersey requires carriers to offer community-rated pricing.

Average Cost of Medicare Supplement Insurance by Age in 2026: Real Rates from NJ Carriers

Average cost of Medicare Supplement insurance by age in 2026 depends on your plan letter, your carrier, and whether you're 65 or 80. The starting premium everyone fixates on? That's only half the story. What your rate looks like at 75 or 83 matters far more to your actual budget.

Here's what NJ carriers are actually charging right now, and how to use that information before your next birthday.

What determines your Medigap premium at each age

Three things drive your rate: the plan letter, your age at enrollment, and the carrier's pricing method. In NJ, carriers must offer community-rated options, which means the base price doesn't increase just because you turn 70.

But block rate increases still happen. When claims in your carrier's insured pool rise, everyone's premium goes up. When age-based increases and block increases stack together, 10-18% jumps in a single year aren't unusual. That's why the carrier you pick matters as much as the plan letter.

2026 monthly rates at ages 65, 70, 75, and 80

Rates vary by carrier, but here's a realistic range for Plan G in New Jersey based on current filings:

Age 65: roughly $130 - $185/month
Age 70: roughly $155 - $220/month
Age 75: roughly $195 - $270/month
Age 80: roughly $240 - $330/month

These are ballpark ranges. Your actual quote depends on gender, tobacco status, and which carrier you choose. A free rate comparison narrows it down fast.

Which plans offer the best value by age bracket

Plan G is the most popular Medigap plan in 2026 for good reason. It covers everything except the Part B deductible ($283/year in 2026). Plan N costs less monthly but adds copays at office visits and the ER.

At 65, Plan N's savings can be meaningful. By 75 or 80, most people prefer Plan G's simplicity since they're seeing doctors more often and want zero surprises on bills.

The starting price trap nobody warns you about

Some carriers price aggressively low to attract new enrollees. The rate at 65 looks unbeatable. By 74, those same plans have had the steepest increases because the carrier built its block on price shoppers, not stable long-term members.

A plan that's $15/month more at 65 but holds steadier over 10 years saves you thousands. I look at a carrier's rate increase history before I recommend anything.

How to lock in a lower rate before your next birthday

Your 6-month Medigap Open Enrollment Period starts the month you turn 65 and are enrolled in Part B. During this window, no carrier can deny you or charge more for health conditions. That's your best shot at the lowest rate.

If you're approaching 65, apply up to 6 months before your Part B start date. Already past 65? Call us. NJ has specific protections, and we can find your best option based on your current health.

Why comparing multiple carriers saves real money

Plan G is Plan G. The benefits are identical by law. The only difference is what you pay and how fast that price climbs. I compare rates from every major NJ carrier so you see the full picture, not just whoever's running the cheapest intro rate this quarter.
