Example: Supplemental Security Income (SSI) counts most unearned income, but a bit less than half of earned income. So, if you have $500 in unearned income and $500 in earned income, your countable income for SSI would be just $697.50, even though your total income would be $1,000. Other programs, such as disability-based MO HealthNet and Medicare Savings Programs often use calculations similar to SSI's.
