Retirement contributions refer to the money that an individual sets aside for their retirement savings. This can include contributions made by both employees and employers to a retirement plan, such as a 401(k) or IRA. The goal of these contributions is to help individuals save enough money over time so they can live comfortably in retirement without having to rely on government assistance programs. Retirement contributions are typically made through automatic payroll deductions and may be invested by the plan's trustee for growth over time.
