When Medicare takes the whole raise — and sometimes the whole check
The Part B premium is a flat $202.90 a month regardless of the size of the benefit it comes out of. At the top of the benefit distribution that is a nuisance. At the bottom it is most of the payment.
2026 Part B standard premium
$202.90
Deducted whole from every benefit it is withheld from. On a $500 monthly payment that is 40.6% of the check.

What actually happens at the bottom
Three different things happen depending on where the benefit sits, and they are genuinely different calculations rather than smaller versions of the same one.
| Benefit before | After the adjustment | Premium charged | Net payment | Billed separately |
|---|---|---|---|---|
| $200 | $205 | $190.00 | $15 | — |
| $300 | $308 | $193.00 | $115 | — |
| $400 | $411 | $196.00 | $215 | — |
| $500 | $514 | $199.00 | $315 | — |
| $600 | $616 | $201.00 | $415 | — |
| $700 | $719 | $202.90 | $516 | — |
The premium never drives the payment negative. Where it exceeds the benefit, the excess is billed rather than withheld — the payment simply stops at zero. Any calculator that returns a negative figure here is not modelling the programme.
What hold harmless does, and does not, do
Below about $639.29 a month, the 2.8% adjustment produces a smaller dollar increase than the +$18 premium increase. Section 1839(f) caps the premium so the net payment cannot fall.
| Benefit before | Premium without the cap | Premium with the cap | Net with the cap | Net without it |
|---|---|---|---|---|
| $200 | $202.90 | $190.00 | $15 | $2 |
| $300 | $202.90 | $193.00 | $115 | $105 |
| $400 | $202.90 | $196.00 | $215 | $208 |
| $500 | $202.90 | $199.00 | $315 | $311 |
| $600 | $202.90 | $201.00 | $415 | $413 |
| $700 | $202.90 | $202.90 | $516 | $516 |
The protection is real and it is narrow: it stops the net payment falling, and it does nothing about the fact that the raise has been fully consumed. Someone protected by hold harmless in a given year receives the same amount as last year — not less, and not more. The provision in full, with its four exclusions.
How many people are down here
SSA publishes the retired-worker population by monthly benefit amount. The bottom of that distribution is not a rounding error.
| Monthly benefit | Beneficiaries | Share | Premium as a share of the benefit |
|---|---|---|---|
| Less than 300.00 | 559,360 | 1.1% | 67.6% |
| 300.00-399.90 | 538,325 | 1.0% | 50.7% |
| 400.00-499.90 | 602,251 | 1.2% | 40.6% |
| 500.00-599.90 | 631,795 | 1.2% | 33.8% |
| 600.00-699.90 | 656,511 | 1.3% | 29.0% |
| 3,300.00 or more | 4,090,673 | 7.9% | — |
Below $600 a month, the standard premium is more than a third of the entire payment. About 3.3% of retired workers receive less than $500 a month.
SSI is a different case entirely, and getting this wrong is the classic error
None of the above applies to a Supplemental Security Income payment. SSI recipients are categorically Medicaid eligible in most states, and their Part B premium is paid by the state under a Medicare Savings Program buy-in — not deducted from the payment. Subtracting $202.90 from the 2026 SSI federal rate is simply wrong, and the engine behind this site refuses to do it rather than returning a plausible wrong number. The SSI figures.
Common questions
What happens if the premium is larger than my benefit?
Nothing is paid out and the balance is billed separately rather than withheld. The payment does not go negative, and the calculators on this site show that case explicitly rather than returning a negative number.
Does hold harmless protect a very small benefit?
It protects it from falling, which is not the same as protecting it from being small. Below about $639.29 a month the Part B increase is capped at the beneficiary's own dollar adjustment, so the net payment holds — but it barely rises either.
Why would someone have a Social Security benefit that small?
A short earnings record, low lifetime earnings, an early claim, or a benefit on someone else’s record. SSA publishes the distribution and the bottom of it is not a rounding error: hundreds of thousands of retired workers sit there.
Is SSI the same situation?
No, and this is the most important distinction on the page. SSI recipients are categorically Medicaid eligible in most states and their Part B premium is paid by the state under a Medicare Savings Program buy-in. No premium should ever be deducted from an SSI payment.
