supplemental income

Side job money

Supplemental income is money earned in addition to one's primary wages or salary.

It typically comes from side jobs, investments, rental properties, or government benefits: She drives for a rideshare app to earn supplemental income.

The term implies secondary status—income that supplements rather than replaces the main source.
