Narrative:

Notified by station operations after takeoff that 884 pounds of cargo were on board but not notified on the cargo load sheet. I blocked out at XA55 and took off at XB10. At XB16 I was notified via ACARS message that 884 pounds of cargo were on board on cargo 3. Cargo load sheet in cargo 3 were reported empty. After sterile period; we corrected the load manifest. As expected with the extra weight in the aft of the aircraft; the load manifest was completely wrong. Center of gravity was off by 5 units; takeoff speeds were miscalculated; we used the 43000 pound speed cards; when we should use the speeds for 45000 pounds; because the extra weight put us in another weight category. With the extra weight; the aircraft did not exceed any limitations and the flight was completed safely and uneventfully.
