Social Security only counts earned income, such as wages or net business income, when calculating benefits.
Investment income, such as dividends, interest, and capital gains, is not considered earned income for Social Security purposes.
However, you may need to pay income taxes on your investment income.
If your total income, including your investment income, is above certain thresholds, you may owe taxes on some of your Social Security benefits.
