150 kg for 12 reps
Estimated one-rep max: about 203 kg (448 lb). The five formulas span 192–216 kg, so treat it as a range rather than a number.

Mean of five published formulas. Range 192–216 kg — above ten reps every formula is extrapolating, so this is a rough guide only.

So is 203 kg a good bench press?
If that lift is a bench press, 203 kg (448 lb) puts a man at 82.5–87.5 kg bodyweight at the 99th percentile of 29,914 judged competition benches — world-class. For a squat or a deadlift the same weight ranks lower, because those lifts are heavier for everyone.

150 kg × 12 — common questions
What is my one-rep max if I lift 150 kg for 12 reps?
About 203 kg (448 lb), taken as the mean of the Epley, Brzycki, Lombardi, O'Conner and Mayhew formulas. Individually they give 192 to 216 kg, so the range is the honest answer — and above ten reps all five are extrapolating past the data they were fitted on.
Is 203 kg a good bench press?
If the lift is a bench press, 203 kg (448 lb) puts a man at 82.5–87.5 kg bodyweight at the 99th percentile of 29,914 judged competition benches — world-class. That population all competed, so it is stronger than a gym average.
What should I warm up with?
The ramp below runs 81 kg × 5, 112 kg × 5, 142 kg × 3, 163 kg × 2, 183 kg × 1, then the working single at 203 kg. It is a conventional ladder rather than a rule; the test is that the last warm-up still moves fast.
