Plan G Cost: What Medicare Supplement Premiums Include

Medicare Supplement Plan G does not have one fixed price: insurers set premiums, so the monthly cost depends on where you live, your age, tobacco use, pricing method, and the company. To estimate your own cost, enter a Plan G monthly premium and any deductible or other monthly health-coverage expenses; the calculator shows the estimated yearly and multi-year premium cost.

Formula

The calculator multiplies the monthly premium by 12 to estimate a year of premiums, then multiplies that amount by the number of years entered.

• prem = the quoted monthly Plan G premium, in dollars.
• yrs = the period being estimated, in years.
• cost = estimated premiums over that period, in dollars.

In symbols: estimated premium cost = monthly premium × 12 × years. The separate monthly output repeats the entered premium as a check. This arithmetic assumes the quoted monthly amount stays unchanged; actual premiums may change over time.

Worked Example

Using the calculator defaults, the monthly premium is $180 and the estimate period is 1 year.

1. Annualize the premium: $180 × 12 months = $2,160.
2. Multiply by the estimate period: $2,160 × 1 year = $2,160.
3. The estimated Plan G premium cost is $2,160, and the monthly premium entered is $180.

This is a multiplication estimate, not a quote. Enter an insurer’s actual monthly price to model that offer; the default is only an example.

What Plan G Covers—and What It Does Not

Medicare Supplement Insurance, also called Medigap, is private insurance that can help pay certain cost-sharing expenses associated with Original Medicare. Plan G is a standardized Medigap plan design: its covered benefit categories are generally the same across insurers, although premiums and service can differ. Availability and the specific enrollment rules that apply can vary, so check current details with Medicare or a state insurance department.

For people who have Original Medicare, Plan G generally covers the Part A hospital deductible and coinsurance, Part B coinsurance or copayments, hospice coinsurance, skilled nursing facility coinsurance, and certain other listed Medicare cost-sharing amounts. It does not cover everything. In particular, a person enrolled in Plan G generally pays the Medicare Part B deductible out of pocket. Plan G also does not cover routine dental, vision, or hearing care, prescription drugs, or long-term custodial care. Separate coverage or personal payment may be needed for expenses outside the plan’s benefits.

Medigap is not the same as Medicare Advantage. A Medigap policy supplements Original Medicare; Medicare Advantage is a different way to receive Medicare benefits. The Plan G premium is generally separate from the Medicare Part B premium, and a person may also have costs for prescriptions or services the policy does not cover.

Why Plan G Premiums Differ

There is no universal Plan G price, and a premium advertised in one place is not a reliable estimate for everyone. Insurers set their prices, and the quote can reflect several factors, including:

• Location: premiums and available policies differ by state, county, or rating area.
• Age and pricing method: insurers may use community-rated, issue-age-rated, or attained-age-rated pricing. These methods affect how a premium is set and how it may change as a policyholder ages.
• Tobacco use: some insurers use tobacco status in pricing.
• Household discounts and other pricing details: an insurer may offer a discount if certain conditions are met; ask how it works and whether it can change.
• Plan type: High-Deductible Plan G has a different premium structure from standard Plan G and requires the policyholder to pay covered costs up to its deductible before the plan pays its share.

Premiums can rise after enrollment. A multi-year calculator estimate that holds the price constant is useful for simple arithmetic, but it does not forecast future price changes, deductibles, medical expenses, or insurer decisions. To compare actual offers, use current written quotes for the same plan type and location, and confirm whether the quote includes discounts or underwriting conditions.

How to Estimate Your Total Cost

Start with the monthly premium quoted for the exact policy you are considering. Check that it is Plan G rather than High-Deductible Plan G, and note whether the amount assumes a discount. Then enter the premium and the period you want to examine. For example, a $180 monthly quote produces a $2,160 one-year premium estimate before other costs.

For a more complete household budget, consider costs that this simple calculator does not add automatically:

• Medicare Part B premiums and the Part B deductible.
• Prescription drug coverage premiums and medication expenses, if applicable.
• Costs for services excluded from Medicare or Plan G, such as routine dental or long-term custodial care.
• Potential premium increases over time.
• For High-Deductible Plan G, the applicable deductible and covered expenses paid before the plan contributes.

Do not treat the premium alone as the total cost of healthcare. It is the recurring price of the policy, while out-of-pocket costs depend on covered services, Medicare’s rules, and the particular policy. Ask the insurer for the policy outline and a dated quote, and verify benefit and enrollment details through official Medicare information.

Choosing and Comparing Quotes

When comparing quotes, make sure each one is for the same Plan G design and effective date. A lower starting premium may reflect a different pricing method or fewer discounts; it does not by itself show how premiums will change. Ask each insurer to explain the rating method, the discount conditions, the policy’s renewal provisions, and whether the price shown is introductory or ongoing.

It is also important to distinguish standard Plan G from High-Deductible Plan G. The latter generally has a lower premium in exchange for more costs paid by the policyholder before coverage begins, but the applicable deductible and terms should be confirmed for the specific policy year. This calculator estimates premiums only; it cannot decide which arrangement fits someone’s needs.

Enrollment rights can affect which policies are available and whether an insurer can use health questions. Those details are not calculated here and should not be assumed based on a price comparison. Check current federal and state information or consult a qualified, unbiased source if you need help understanding enrollment options.

Frequently Asked Questions

How much does Medicare Plan G cost per month?
There is no single monthly price. The amount varies by location, insurer, age and pricing method, tobacco status, discounts, and whether you choose standard or High-Deductible Plan G. Use a current quote for your circumstances.

Does Plan G have a deductible?
With standard Plan G, the Medicare Part B deductible is generally not covered, so the beneficiary pays it. High-Deductible Plan G has a separate plan deductible structure; confirm the current amount and policy terms.

Does the Plan G premium include Medicare Part B?
No. The Medigap premium is separate from the Medicare Part B premium. Part D drug coverage, if purchased, is also separate.

Can Plan G premiums increase?
Yes. A premium is not necessarily fixed for life. The insurer’s pricing method and other factors can affect changes, so ask how premiums are set and review notices about any increase.

Is High-Deductible Plan G the same as Plan G?
It has a related standardized benefit design but uses a deductible structure that makes the policyholder pay certain covered costs up to the deductible before the plan pays. Its premium and out-of-pocket pattern differ from standard Plan G.

Does this calculator include medical bills?
No. It estimates premiums only. It does not include the Part B deductible, uncovered services, prescription expenses, deductible payments, or future premium changes.

The result is an estimate based on the premium and period you enter; get the exact policy price and coverage details from the insurer and verify Medicare information through official sources.
