Unlike Medicare Part B, which has a standard national premium, Medigap pricing is set entirely by private insurers and regulated at the state level. That means your neighbor two states away could be paying half — or double — what you pay for the exact same Plan G benefits. This guide explains what actually drives Medigap pricing and how to shop smart regardless of where you live.
The Three Ways Insurers Price Medigap
| Pricing Method | How It Works | Long-Term Impact |
|---|---|---|
| Community-rated | Everyone pays the same premium regardless of age (may still adjust for inflation) | Predictable; doesn’t rise just because you get older |
| Issue-age-rated | Premium is based on your age when you first bought the policy and never increases due to aging | Buying young locks in a lower base rate for life |
| Attained-age-rated | Premium starts lower but increases every year as you get older | Cheapest at first, but rises steadily over decades |
Attained-age-rated policies are the most common nationally and often look like the cheapest option when you first enroll — but they can become significantly more expensive over a 15–20 year retirement. Community-rated and issue-age-rated policies tend to be more predictable over the long run, even if the starting price is higher.
Why State Matters So Much
Each state’s insurance department regulates Medigap differently — some mandate community rating (Arkansas, Connecticut, Massachusetts, Maine, Minnesota, New York, Vermont, and Washington are commonly cited examples), some allow all three pricing methods, and some states have far more competing carriers than others, which drives prices down through competition. States with fewer insurers or stricter guaranteed-issue mandates (which spread risk across a broader population) tend to have higher average premiums, while states with more competition and looser rules often show a wider range of prices — meaning more opportunity to shop around and save.
Other Factors That Affect Your Premium
- Age: Especially under attained-age-rated policies, premiums typically rise with age.
- Gender: Many insurers price men and women differently, reflecting differing average healthcare utilization.
- Tobacco use: Smokers typically pay a surcharge, similar to life insurance pricing.
- Household discounts: Many carriers offer a discount (often 5–12%) if you or a spouse/partner also holds a policy with them.
- Plan letter: More comprehensive plans like G cost more than leaner options like A or high-deductible variants.
- Carrier overhead and claims history: Larger, more efficient insurers can sometimes offer lower rates for identical coverage.
Typical Premium Ranges by Plan (National Snapshot)

| Plan G | $120–$300+ |
| High-Deductible Plan G | $40–$90 |

The High-Deductible Plan G Option
For budget-conscious shoppers, High-Deductible Plan G offers the same comprehensive benefits as standard Plan G, but you pay a set annual deductible out of pocket before the plan starts covering costs. In exchange, the monthly premium is dramatically lower — often a fraction of standard Plan G. This can be an excellent option for healthy retirees who want catastrophic protection without paying for first-dollar coverage they may not use.
How to Actually Lower Your Medigap Cost
- Compare multiple carriers for the same plan letter — since benefits are identical, price is the main variable. See Medigap Plan Letters Explained for what each letter covers.
- Consider Plan N instead of Plan G if you don’t mind small copays — see our Plan G vs. Plan N comparison.
- Ask about household/multi-policy discounts.
- Re-shop periodically even after you’re enrolled — switching carriers for identical coverage at a lower price is possible in many cases. See Switching Medigap Plans.
- Enroll during your Open Enrollment window to guarantee the best available rate without underwriting — see Medigap Open Enrollment Period.

Frequently Asked Questions
- Why does Medigap cost so much more in some states?
- Pricing rules, the number of competing carriers, and state-level guaranteed issue mandates all affect average premiums, which is why identical coverage can cost very different amounts depending on where you live.
- Will my Medigap premium go up every year?
- It depends on the pricing method. Attained-age-rated policies typically increase as you age; community-rated and issue-age-rated policies are more stable but can still rise with inflation and claims trends.
- Is High-Deductible Plan G a good deal?
- It can be, especially for healthy retirees who want lower premiums and are comfortable paying a set deductible before coverage kicks in for cost-sharing.
