Automatic plan features like auto-enrollment and auto-escalation can help more Americans save for retirement by addressing issues like procrastination and inertia. Auto-enrollment automatically enrolls employees in a 401k plan at a default contribution rate, often 3%, unless they opt out, nearly doubling participation. Auto-escalation periodically increases the default contribution rate to keep participants on track to meet savings goals. However, these features also create challenges, as auto-enrollment alone may leave some workers stuck at low savings rates and increased automatic contributions burden employers with higher costs and administrative requirements.
