How to Bench Press Calculator

▾

1Epley formula: 1RM = Weight × (1 + Reps / 30)
2Brzycki formula: 1RM = Weight / (1.0278 − 0.0278 × Reps)
3Most accurate when reps are in the 3–10 range; less reliable above 15

Worked Examples

▾

Example 1

Given:80kg for 8 reps (Epley)

Result:1RM ≈ 101kg

80×(1+8/30) = 80×1.267 = 101.3
