Many employers offer matching contributions, usually around 3% or 4% of your annual salary. If your employer offers a match of 3% and you put 3% of your salary into your retirement account, your employer will match that contribution dollar-for-dollar. But let’s say you put 10% into your retirement account, the employer’s contributions will stay at 3%. Employer matches are more common in 401(k) plans than 403(b) plans.
