The Calvert Foundation’s Community Investment Note lets users invest as little as $20 online in a host of social enterprises.

According to the foundation, investors can expect a 1% return over a year, 2% over five years, and 4% for a 15-year note. Calvert doesn’t invest in public companies, and investors will only fund enterprises that focus on creating social or environmental change.

The portfolios combined returned almost 19% from their inception in September 2016 through August 2017, according to Swell.
