Your one-rep maximum is the most accurate measure of your strength. A bench press calculator gives you that number without the risk of maxing out under the bar. Instead of grinding through heavy singles, enter a submaximal set and let the bench press calculator estimate your true max safely.

Why Use a Bench Press Calculator?
Safer Training
No need to max out under the bar. Get a reliable 1RM estimate from a submaximal set.
Track Progress
Measure strength gains over weeks and months with consistent, repeatable data.
Program Weights
Use your 1RM to calculate exact training loads for strength, hypertrophy, or endurance.
How the Bench Press Calculator Works
Using this bench press calculator is simple:
- Pick a challenging weight and warm up properly.
- Lift the weight to muscular failure — as many reps as you can.
- Enter the weight and reps into the bench press calculator above.
- Read your estimated one-rep max from the results.
Tip: Aim for 6–8 reps for the most accurate bench press calculator result. Then try 90% of your estimated 1RM next session to refine the prediction further.
Bench Press Calculator Formulas
This bench press calculator uses the Epley formula as its default — the most widely used 1RM equation in strength training:
1RM = w × (1 + r / 30)
Where w = weight lifted and r = reps completed. The bench press calculator also cross-references four additional formulas for a more complete estimate.
formulas.epleyTitle
1RM = w × (1 + r / 30)
The most widely used formula in strength training, developed by Boyd Epley. Simple, effective, and accurate for most rep ranges.
formulas.brzyckiTitle
1RM = w × (36 / (37 - r))
Created by Matt Brzycki. Particularly accurate for rep ranges of 1 to 10 and commonly used in academic strength research.
formulas.landerTitle
1RM = (100 × w) / (101.3 - 2.67123 × r)
Derived from regression analysis of actual 1RM tests. Good balance of accuracy across different rep ranges.
formulas.lombardiTitle
1RM = w × r0.10
Uses an exponential approach. Gives slightly different results at higher rep ranges, useful for cross-referencing your estimate.
formulas.oconnerTitle
1RM = w × (1 + 0.025 × r)
A straightforward linear model. Quick to compute and provides reasonable estimates across most common rep ranges.
Bench Press Calculator Chart
Use the bench press calculator chart below to plan your training loads. After calculating your 1RM with the bench press calculator above, find the right percentage for your goal: 85–95% for strength, 65–80% for hypertrophy, or 50–65% for endurance.
lbs
Strength
95%--1-2 reps
90%--2-3 reps
85%--3-5 reps
Hypertrophy
80%--4-6 reps
75%--6-8 reps
70%--8-10 reps
Endurance
65%--10-12 reps
60%--12-15 reps
50%--15-20 reps
Incline Bench Press
Upper Pecs
Primary
Anterior Deltoids
Secondary
Triceps
Stabilizer
The incline bench press targets the upper pectoral muscles and increases shoulder activation compared to flat pressing. Set the bench at 15–30 degrees for best results. Use the bench press calculator to find your incline 1RM — most lifters incline press about 65–75% of their flat bench max.
Proper incline bench press form:
- Set bench incline to 15–30 degrees. Feet flat on the floor.
- Grip the bar slightly wider than shoulder-width and unrack.
- Lower the bar to your upper chest, then press upward to full extension.
- Breathe and repeat for the desired number of reps.
Decline Bench Press
The decline bench press isolates the chest more than flat or incline pressing. Many experienced lifters prefer it for pectoral development and reduced shoulder strain. Use the bench press calculator to estimate your decline 1RM — it typically runs close to or slightly above your flat bench max.
Always use a full grip (thumb wrapped around the bar) and have a spotter when going heavy.
False Grip
Thumb on the same side as fingers. Dangerous if the bar slips.
Full Grip
Thumb wrapped around bar. Safe and recommended.
Decline bench press form:
- Hook your feet under the pad. Grip the bar outside shoulder width.
- Unrack with a spotter and lower the bar to your lower chest.
- Press back up to full extension. Repeat for planned reps.

Frequently Asked Questions
A 1-rep max is the maximum amount of weight you can lift for a single repetition with good form. It is the gold standard measure of strength in weightlifting.
Our calculator uses the most reliable formulas in sports science (including Epley and Brzycki). It is highly accurate, especially when your input is between 3 to 8 reps.
Testing a true 1RM places extreme stress on your nervous system and joints, which can lead to injury. A calculator gives you an accurate max based on a safer submaximal set.
Yes, always include the weight of the barbell. A standard Olympic barbell weighs 45 lbs (20 kg).
Yes! While optimized for the bench press, the formulas used (Epley, Brzycki, etc.) apply equally well to the squat, deadlift, and overhead press.
