Hello guys I am trying to figure something out about thrust reductions after takeoff. So when rolling down the runway I have my takeoff thrust set, after liftoff, what altitude AGL or MSL is that thrust reduced at? And by how much n1 power is the takeoff thrust reduced by? Thanks!

I tend to reduce thrust around 1000ft-1500ft above the airport altitude. It’s often that sort of altitude IRL as well (dependent on any departure route restrictions).
I tend to go between 2-5%. I find that works for me.

Okay I appreciate it.
Climb power is usually set between 800 and 1500 ft AFL. For standard NADPs (noise abatement departure procedures), this occurs at 800 ft AFL.
The reduction amount depends on the aircraft, any conditions affecting takeoff thrust, and use of takeoff and/or climb derate. If you don’t have all that figured out, 2-5% N1 is usually good.
Alright thank you very much!

For me, after about 1000-1500ft AGL I tend to set climb thrust about 5-10% N1 below toga (depending on weight and aircraft).
Alright thanks!
