I can't seem to grasp how to calculate the values for a common emitter with a load resistance, to cascade an amplifier in multiple stages.

I'm trying to obtain an 8.5-9Vptp output from a 12V supply on a 5520 ohm load resistance. Not trying to achieve much gain since it can be achieved in earlier stages so ~5. I took:

Ic = 10mA

DC emitter 0.5V about ground

Vce min = 1V

This is what I've got

However, once I actually built the circuit on a breadboard the output gain ended up being 4Vptp, half of what I actually had in the simulation. What am I doing wrong?
