Start with a monthly paycheck of $317 and a federal benefit rate of $994, and the Social Security Administration’s own worked example lands on a federal Supplemental Security Income payment of $878. In a state that tops that up with a $15 supplement for a person living alone, the total becomes $893. Those numbers come straight from SSA’s page on how earned income is counted, and they show how a small job changes an SSI check without erasing it.

Walking $317 in wages through SSA’s three subtractions

SSA’s rule for work income is stated plainly: the first $65 of earnings and one half of earnings over $65 received in a month are not counted. Ahead of that, the worked examples take out a general $20 exclusion. The agency’s Example B applies all three steps to $317 in gross wages.

• Start with $317 in gross wages for the month.
• Subtract the $20 that is not counted, leaving $297.
• Subtract the $65 earned income exclusion, leaving $232.
• Count only half of that remainder, which is $116 of countable income.

The countable $116 is then subtracted from the federal benefit rate. SSA’s federal benefit rate page lists $994 a month for an eligible individual in 2026, a rate that took effect in January 2026 after a 2.8 percent cost-of-living increase. Taking $116 from $994 leaves $878, the figure in the headline. The couple’s rate on the same page is $1,491, but the example concerns one person.

The people affected are SSI recipients who work part-time or return to work, along with anyone who lives with one and helps with the household accounts. What they have to decide is whether the monthly figure on the award letter still matches the wages being reported, and whether they live in a state that adds a supplement. That second question is the one the headline hangs on, because SSA’s $15 is an illustration for an individual living alone, not a number every recipient gets.

For recipients planning ahead on wages, The SSI & Disability Action Kit covers the rules for working without losing benefits, set out next to the SSA formula above.

The result of the example is worth stating in budget terms. A person who earned $317 in the month ends up with $317 in wages plus an $878 federal payment, or $1,195 before any state money. The paycheck cost $116 of benefit, not $317. The first $85 of earnings is excluded outright and half of the rest is excluded too, which is the design behind the rule.

Why the order of the subtractions matters

The sequence in SSA’s example is $20 first, then $65, then half. That order is not cosmetic. Reversing it, by halving the amount after the $65 and only then removing the $20, produces countable income of $106 instead of $116. A $106 figure would imply a federal payment of $888, ten dollars higher than the one SSA publishes. That reversed figure is this article’s own arithmetic, offered only to show the sequence matters; it is not something SSA states, and SSA’s order is the one that governs.

The practical lesson for anyone checking a notice is to start from the agency’s layout and not from a calculator shortcut. An organizer that subtracts $65 first and halves the rest will come out ten dollars off, and a ten-dollar error repeated across months becomes a reporting problem.

What the $15 state supplement is, and what it is not

Example D in the same SSA page repeats the calculation and adds one line: $878 as the SSI federal benefit, plus $15 described as a state supplement payment for an individual living alone, for $893 in total federal and state SSI. The headline begins with “a state that adds its own money” for that reason. The federal $878 holds everywhere the example’s facts hold. The extra $15 exists only where a state pays a supplement, and the amount depends on the state and on living arrangements.

The page does not say which states pay a supplement, and this piece does not name any. The $15 should be read as SSA’s teaching figure, not as a standard rate. A recipient who lives with others, or in a state with no supplement, would look at the federal line alone.

It is also true that the example is one month with one set of wages. SSI is recalculated month by month, so a month with $317 in wages and a month with none produce different checks. The countable figure follows the earnings, and the formula resets every month.

Checking a work-income month against SSA’s page

The free official route is SSA’s own explanation, the earned income examples page, which sets out each step with figures. Pair it with the federal benefit rate table so the starting number is the current one.

Before comparing, it helps to gather the month’s gross wages from the pay stub, the amount on the most recent SSA notice, and any state supplement shown on it. Run the steps in SSA’s order, $20, then $65, then half, and subtract the result from the federal rate. If the answer differs from the notice, the mismatch is worth raising with the local Social Security office, since the example on SSA’s page shows a $317 month ending at $878 federal and $893 with the $15 supplement.

The SSI & Disability Action Kit pairs the rules for working without losing benefits with an income and resource organizer, which suits the monthly tracking the outro describes.
