Luckily the designers of the airplane knew calculation inflight is for practical purposes impossible.

We calculate (read from a table) the EO ACC alt during the flightdeck preparation. Then use MCDU page TAKEOFF PERF to enter a reminder, key 5R off the top of my head. Once you lose the engine (about 10x a year in the SIM) you decrease the pitch and start accelerating at or above it. No calculations required, you just read the figure from MCDU and compare to the indication of the altimeters.
