Collin County Retirement Plan Briefing September 7, 2010

How Your Plan Works

A percentage of your employee’s paycheck is deposited into his or her TCDRS account. Your employee’s savings grow at an annual, compounded rate of 7% regardless of market ups or downs. You are also saving for your employee’s retirement. Your employer contributions become matching dollars for employees that retire. Your rate is determined annually based on your projected assets and estimated benefits promised. At retirement, you match the employee’s final account balance, including interest, $2.50 for every dollar saved. We calculate a monthly retirement payment based on that account balance and matching. Your retiring employee receives a monthly benefit payment for life. Five Simple Steps
