Estimated one-rep max: about 147 kg (323 lb). The five formulas span 142–151 kg, so treat it as a range rather than a number.

So is 147 kg a good bench press?
If that lift is a bench press, 147 kg (323 lb) puts a man at 82.5–87.5 kg bodyweight at the 78th percentile of 29,914 judged competition benches — advanced. For a squat or a deadlift the same weight ranks lower, because those lifts are heavier for everyone.

130 kg × 4 — common questions
What is my one-rep max if I lift 130 kg for 4 reps?
About 147 kg (323 lb), taken as the mean of the Epley, Brzycki, Lombardi, O'Conner and Mayhew formulas. Individually they give 142 to 151 kg, so the range is the honest answer.
Is 147 kg a good bench press?
If the lift is a bench press, 147 kg (323 lb) puts a man at 82.5–87.5 kg bodyweight at the 78th percentile of 29,914 judged competition benches — advanced. That population all competed, so it is stronger than a gym average.
What should I warm up with?
The ramp below runs 59 kg × 5, 81 kg × 5, 103 kg × 3, 117 kg × 2, 132 kg × 1, then the working single at 147 kg. It is a conventional ladder rather than a rule; the test is that the last warm-up still moves fast.
