Narrative: During initial climbout; I was the pilot flying. We were flying runway heading off of [Runway] XX to 4;000 feet as assigned. We had not yet received our clearance to climb higher. I began to reduce power and pitch in order to level off at 4;000. At 3;500 feet; and speed 240 KIAS; we were instructed to climb and maintain 10;000 MSL. I then smoothly added thrust and adjusted pitch to continue climbing utilizing FLC. Once I increased thrust; there was a loud bang; followed by the engine indications and crew alerting system indicating engine # 1 was out. Additionally; a yawing tendency towards the INOP engine. Once identified by both pilots; controls were transferred to the Captain and I assumed PM duties. Normal checklists were complete; ATC and company was notified and the QRH procedure for engine out was accomplished. Engine fluid levels were normal; and the engine was shut down; which did not require the pulling of the #1 fire extinguishing handle. Once concluded a restart was not advised after discussion; due to the loud bang and sudden shutdown; we then were directed by the QRH to execute one engine inoperative approach and landing. The FA was notified and provided a [crew] brief; followed by the passenger announcement. We then coordinated with ATC for radar vectors for the visual; backed up by the  RNAV XX in ZZZ. Once landed; we stopped on the runway; had the engine inspected by the ZZZ fire department. Verification was made that there was no fire; fluid leakage and we then taxied off the runway and parked at [the] gate for deplaning.   Loud bang; aircraft yaw and EICAS indications by both pilots leading to the engine out procedure. Cause is still to be determined; from the initial inspection; the mechanical issue caused small metal fragments found in the compressor blades. After identifying the issue; we transferred flight controls; had a brief discussion and executed the pertinent QRH procedures for engine failure and a single engine approach and landing. No suggestions to report at this time.


Second narrative: We were climbing out of ZZZ of Runway XX on runway heading and were just about to level off at 4;000 ft so the FO (PF) reduced thrust. Just before we leveled off we were given a continued climb up to 10;000 ft. While reintroducing thrust at 4;000 ft we heard a loud bang followed by aircraft yaw.  I immediately looked at the EICAS and saw an abrupt stop in the #1 engine. I called for my Aircraft.  The First Officer and I briefly discussed the situation then promptly ran the QRH for Engine OUT. The engine was shut down and our fluid levels (hydraulic/oil) looked normal so we decided against pulling the fire extinguishing handle. We discussed the possibility of restarting the engine but decided against it because of the loud bang we had heard followed by the abrupt shutdown of the engine. We were then led to [procedure] and proceeded to get set up for the Single engine approach.  After finishing talking to the passengers; flight attendant and sending a message to dispatch we completed all other  normal checklists. We then executed the visual approach backed up by RNAV RWY XX into ZZZ without any further event. We landed and had the fire department check out our engine for signs of smoke; fire; or fluid leak and then proceeded to the gate.The first indication of the Engine failure was a loud bang followed by aircraft yaw. We then looked at the EICAS and saw the indications of a #1 engine failure.  We were not given a definitive cause for the failure. It seems to have been a mechanical issue inside the Engine. Upon inspection after landing chunks of metal were found inside the compressor blades. After noticing the event. We transferred  flight controls then briefly discussed our situation and decided to run the checklist for Engine Failure in the QRH .


Synopsis: EMB-145 flight crew reported an engine failure on takeoff resulting in an air turn back and a precautionary landing.
