Best Medicare Supplement Plans in New Jersey (2026)

Three insurers have New Jersey's lowest Medicare Supplement (Medigap) rates for 65-year-olds on the most popular plans, based on quotes MoneyGeek collected from Medicare.gov. Bankers Fidelity charges $160 monthly for Plan G, $83 below the state Plan G average, and AFLAC's Plan N costs $118 monthly. LifeShield National and Bankers Fidelity tie for Plan F at $198, though Plan F is sold only to people eligible for Medicare before 2020.   

Plan letters are standardized, so each letter covers the same costs at every insurer, and Plans K and L trade lower premiums for sharing costs with you. Your final cost depends on the insurer, your age and its pricing style. Attained age pricing raises your premium as you age, while issue age pricing bases it on your age when you buy.

The seven lowest Plan G rates in New Jersey range from $160 to $181 per month for 65-year-olds. Bankers Fidelity has the lowest rate in MoneyGeek's data at $160 monthly, $83 below the $243 state Plan G average. LifeShield National charges $165 monthly and Bankers Life charges $166 monthly.

The seven lowest Plan F rates for New Jersey residents age 65 range from $198 to $229 monthly, but Plan F is sold only to people eligible for Medicare before Jan. 1, 2020, such as those who qualified early through disability.   

LifeShield National and Bankers Fidelity tie at $198, 33% below the $297 state Plan F average. AFLAC follows at $209 monthly. These three insurers cost $1,056 to $1,188 a year less than the state average. Plan F covers everything Plan G does plus the Medicare Part B deductible.

AFLAC charges $118 monthly for Plan N. This is the lowest rate in our quotes for New Jersey residents age 65, $75 below the $193 state Plan N average. LifeShield National and Mutual of Omaha both price Plan N at $120 monthly.   

Plan N charges copays of up to $20 for some office visits and up to $50 for ER visits that don't lead to a hospital admission, and it doesn't cover Part B excess charges, the amount above Medicare's approved rate that some doctors bill. In exchange for these copays, AFLAC's Plan N costs $42 a month less than the cheapest Plan G.

*Savings compare each rate with the New Jersey Plan N average of $193 a month ($2,316 a year) for 65-year-olds.

Your best Medicare Supplement plan depends on age and plan type. At 65, Mutual of Omaha has the lowest Plan A rate at $129 a month, $35 below LifeShield National. Filter by plan type, age and high-deductible option to see rates for your profile.

Average Medicare Supplement premiums for New Jersey residents age 65 range from $109 monthly for Plan K to $310 for Plan C, averaging $219 across the 10 plan types. Among the most popular plans, Plan N averages $50 a month less than Plan G, and Plan F averages $54 more.   

Each insurer sets its own price for each plan letter and files it with the New Jersey Department of Banking and Insurance, so a plan with less coverage can still cost more on average. Plan B averages $18 a month more than Plan G, and Plan C averages $13 more than Plan F.

Pick the Medicare Supplement plan type that fits the care you expect, then the cheapest financially stable insurer that sells it.

We scored New Jersey Medigap companies across three categories to create a weighted score out of 5:

• Affordability (50%): Lower monthly premiums earn higher scores.
• Pricing style (20%): We scored pricing methods based on long-term stability and fairness, with community rating highest, then issue age, then attained age. A community-rated plan with slightly higher costs can outscore a cheaper attained-age plan because community-rated premiums don't rise because you get older.
• Plan availability (30%): Insurers offering more plan types score higher. We weighted popular plans (G, F and N) more heavily in scoring.

Each category is scored out of 5, and the three weighted category scores add up to the overall MoneyGeek rating. Plan-type averages are the average monthly rate across the insurers we quoted for each plan.
