Optimize your upper chest development with our Incline Bench Press Calculator. This tool uses scientifically backed formulas to estimate your one-repetition max (1RM) and training percentages based on your recent performance.
Incline Bench Press Calculator
Incline Bench Press Calculator Formula
Brzycki Formula: 1RM = W ÷ (1.0278 – (0.0278 × R))
Epley Formula: 1RM = W × (1 + (R ÷ 30))
Variables:
- W (Weight): The total load you lifted during a set (including the bar).
- R (Reps): The number of successful repetitions performed before reaching failure.
- 1RM: The theoretical maximum weight you could lift for a single rep.

What is an Incline Bench Press Calculator?
The incline bench press calculator is a fitness tool designed to predict your maximal strength capabilities on the incline press. Unlike the flat bench, the incline version specifically targets the clavicular head of the pectoralis major (the upper chest) and the anterior deltoids.
By inputting the weight you can lift for multiple repetitions, the calculator applies mathematical models to estimate your one-rep max. This is essential for powerlifters and bodybuilders to determine appropriate training loads for specific hypertrophy or strength blocks.
How to Calculate Incline Bench Press Max (Example)
Follow these steps to estimate your max manually:
- Choose a weight that you can lift for 3 to 10 repetitions with good form.
- Perform the set and record the exact number of clean reps (e.g., 200 lbs for 5 reps).
- Multiply the reps by 0.0278: 5 × 0.0278 = 0.139.
- Subtract that from 1.0278: 1.0278 – 0.139 = 0.8888.
- Divide your weight by that result: 200 ÷ 0.8888 = 225 lbs.
Frequently Asked Questions (FAQ)
Is the incline bench press harder than flat bench? Yes, most lifters find their incline press is 10-20% lower than their flat bench due to the increased involvement of the shoulders and decreased chest leverage.
What is the best angle for incline bench? A 30 to 45-degree angle is optimal. Higher angles tend to shift the load too heavily onto the front deltoids.
How accurate are these formulas? They are highly accurate for reps under 10. Once you exceed 12-15 reps, the correlation between endurance and maximal strength weakens.
Should I test my actual 1RM? Calculating it is safer for most lifters. Actual 1RM testing should only be done with experienced spotters and a proper peak phase.
