Narrative:
On climbout the number one engine overheat illuminated. I was the pm. We complied with the QRH procedures and declared an emergency. I completed the checklist up until the one engine inoperative landing checklist and then transferred control; so that I could conduct the landing. In the rush I inadvertently calculated the landing weight incorrectly; which resulted in an overweight landing. I did not discover the error until after we landed and I talked to the dispatcher. The actual landing weight was calculated by dispatch as 128;300 pounds.I had calculated 125;300 pounds. Because of the proximity to the landing field; I only had time to notify base operation to relay to dispatch of our situation and that we were returning to [departure airport.] dispatch did not have time to contact us airborne to relay the landing data; which we had already calculated. The computation confusion came about as everything was very rushed while trying to complete the QRH procedures and prepare for landing in a very short amount of time. I discussed the issue with the dispatcher and entered the overweight landing in the logbook. I also discussed the issue with maintenance control.
