How does the bench press calculator work?
This bench calculator takes a set you have done, such as 185 lb for 6 reps, and estimates the most you could bench for one rep. It runs your set through seven published 1RM formulas and shows the average as “Your bench max”, with the range underneath. It is the same engine as our main 1RM calculator, set up for the bench press.
For example, 225 lb for 5 reps gives an estimated bench max of about 259.9 lb. In kilograms, 100 kg for 5 reps gives about 115.5 kg. Your projected max bench is shown with a range underneath. A 1 rep set simply returns the weight you lifted, because that is already your max for the day.
Pick Dumbbells to enter the weight of one dumbbell. You will get your dumbbell bench press max per hand, and the plate loading is switched off. Pick Paused if you paused each rep on your chest, so you know the result is a paused bench max.
Why use a bench press calculator instead of maxing out?
A bench press calculator gives you a working number without the risk and fatigue of a true max attempt. You can use it every week from your normal sets, track your bench PR over time, and plan your next block. Most lifters only need a real max test before a meet. The rest of the time, this bench press calculator is enough.
Which 1RM formulas work best for the bench press?
Some of these formulas were developed from bench press data. Mayhew’s equation, for example, came from a study of bench press strength in college men and women. Still, the formulas do not agree exactly. For 225 lb × 5 reps, here is what each one says:
| Formula | Estimated 1RM | vs average |
|---|---|---|
| Epley | 262.5 lb | +2.6 lb |
| Brzycki | 253.1 lb | −6.7 lb |
| Lander | 255.8 lb | −4 lb |
| Lombardi | 264.3 lb | +4.4 lb |
| Mayhew et al. | 267.8 lb | +7.9 lb |
| O’Conner et al. | 253.1 lb | −6.7 lb |
| Wathan | 262.3 lb | +2.5 lb |
| Average | 259.9 lb | – |
In a study of seven common equations, all of them tracked real bench maxes closely, but the average error was meaningful for most of them (LeSuer and colleagues, 1997). That is why we show the average and the full range rather than trusting one formula. Another study found that a 5-rep max predicted bench press strength more accurately than sets of 10 or 20 (Reynolds and colleagues, 2006). So for the best bench 1RM estimate:
- Use a set of 3 to 6 reps taken close to failure.
- Use your normal competition-style grip and setup.
- Use a set you did when fresh, not the last set of a long workout.
How do grip width, pause and arch change your bench max?
Your bench PR depends on how you bench. The bench press calculator can only work with the set you give it, so enter a set done with the same technique you want the max for.
Grip width
A wider grip shortens the distance the bar travels and puts more work on the chest. A closer grip makes the bar travel further and puts more work on the triceps. Most lifters bench a little less with a close grip. If you want your close-grip bench max, enter a close-grip set.
Paused vs touch-and-go
Touch-and-go means you lower the bar and press straight back up. Paused means the bar stops on your chest before you press. In powerlifting meets the bar must stay still on the chest until the referee says “press”, so competitive lifters train paused reps. Most people can lift a bit more touch-and-go because they use the bounce out of the bottom. If you compete, use paused sets for your estimate.
Arch and leg drive
An upper-back arch with your shoulder blades pulled together gives you a stable base and a shorter bar path. Leg drive, pushing your feet into the floor, helps you stay tight. Both usually help people press more. Keep your glutes on the bench. Powerlifting rules require it, and it keeps the lift honest.
Every setting in the bench press calculator, from grip style to paused reps, only changes the label on your result. The maths stays the same, so enter a set that matches the bench you want a max for.
What is a bench percentage chart?
Once you know your bench max, you can plan training with percentages of it. The results panel shows these for your own number. Here is an example for a 225 lb bench max, rounded to 5 lb:
| % of 1RM | Weight | Reps (approx.) | Often used for |
|---|---|---|---|
| 100% | 225 lb | 1 | Max strength |
| 95% | 215 lb | ~2 | Max strength |
| 90% | 205 lb | ~4 | Max strength |
| 85% | 190 lb | ~6 | Strength |
| 80% | 180 lb | ~8 | Strength |
| 75% | 170 lb | ~11 | Hypertrophy |
| 70% | 160 lb | ~14 | Hypertrophy |
| 65% | 145 lb | ~17 | Size + endurance |
| 60% | 135 lb | ~20 | Size + endurance |
| 55% | 125 lb | 20+ | Warm-up |
| 50% | 115 lb | 20+ | Warm-up |
And for a 100 kg bench max, rounded to 2.5 kg:
| % of 1RM | Weight | Reps (approx.) | Often used for |
|---|---|---|---|
| 100% | 100 kg | 1 | Max strength |
| 95% | 95 kg | ~2 | Max strength |
| 90% | 90 kg | ~4 | Max strength |
| 85% | 85 kg | ~6 | Strength |
| 80% | 80 kg | ~8 | Strength |
| 75% | 75 kg | ~11 | Hypertrophy |
| 70% | 70 kg | ~14 | Hypertrophy |
| 65% | 65 kg | ~17 | Size + endurance |
| 60% | 60 kg | ~20 | Size + endurance |
The rep counts are estimates. On a hard day you may get fewer, on a good day more. For a printable version with every percentage and a quick lookup grid, see the 1 rep max chart.
What is my bench press max for 3, 5 or 8 reps?
The bench press calculator’s Coach mode shows your estimated rep maxes from 2RM to 12RM, which acts as a max rep calculator for the bench. For a 225 lb bench max:
| Rep max | Weight | % of 1RM |
|---|---|---|
| 1RM | 225 lb | 100% |
| 2RM | 210 lb | 94% |
| 3RM | 205 lb | 92% |
| 4RM | 200 lb | 89% |
| 5RM | 195 lb | 87% |
| 6RM | 190 lb | 84% |
| 7RM | 185 lb | 82% |
| 8RM | 180 lb | 80% |
| 9RM | 175 lb | 78% |
| 10RM | 170 lb | 76% |
You can convert any rep max back and forth on the rep max converter.
How should I warm up for a heavy bench?
A good warm-up gets you ready without tiring you out. A common pattern is an empty bar for 8 to 10 reps, then a few sets that get heavier while the reps drop. The bench press calculator builds this for your top set, with plates for each set. Here is an example for a 205 lb top set on a 45 lb bar:
| Set | Weight | Reps | Plates per side (lb) |
|---|---|---|---|
| Empty bar | 45 lb | 8-10 | bar only |
| 40% | 80 lb | 5 | 10 + 5 + 2.5 |
| 60% | 125 lb | 3 | 35 + 5 |
| 75% | 155 lb | 2 | 45 + 10 |
| 85% | 175 lb | 1 | 45 + 10 + 10 |
| 92% | 190 lb | 1 | 45 + 25 + 2.5 |
| Top set | 205 lb | as planned | 45 + 35 |
This is a starting point, not a rule. Add a set if you feel stiff, or skip one if you feel great. The warm-up calculator does this for any lift.
How do I test my bench max safely?
The bench press is the lift where people get stuck under the bar. If you want to test a true bench 1RM, set things up first:
- Use safety arms or a spotter. In a power rack, set the safety arms just below your chest at the bottom of the rep. If you use a spotter, agree on the lift-off and when they will take the bar.
- Use a full grip. Wrap your thumbs around the bar. A thumbless grip can let the bar roll out of your hands.
- Warm up, then climb slowly. After your warm-up, try singles at about 90%, then 95%, of your estimated max. Only try a new max if those moved well.
- Rest 3 to 5 minutes between heavy singles.
- Stop when form breaks. If the bar stalls, your butt lifts or your elbows flare hard, that is your max for the day.
If you train alone without safety arms, do not test a max. Use a heavy set of 3 to 5 and let the bench press calculator estimate it. Read the full guide on how to test your 1RM safely.
How can I raise my bench press?
A bigger bench comes from a few simple habits done for months, not weeks.
- Bench more than once a week. Practice improves technique. Many lifters bench two or three times a week at different weights.
- Add weight or reps slowly. Small jumps, like 2.5 to 5 lb, add up. Micro plates help once progress slows. See our guide to progressive overload.
- Train the helpers. Close-grip bench, dips, overhead press and rows build the triceps, shoulders and upper back that support your bench.
- Use percentages or RPE. Base your working sets on your bench max, or use the RPE calculator to adjust for how you feel on the day.
- Sleep and eat enough. Strength gains need recovery.
Come back to this bench press calculator after each training block and enter your best heavy set. Watching your estimated bench max climb is one of the simplest ways to see your progress.

Frequently asked questions
How do I calculate my bench max?
Bench a weight for 3 to 6 good reps, then enter the weight and reps above. The bench press calculator applies seven 1RM formulas and shows the average. For example, 185 lb for 6 reps gives a bench max of about 219.3 lb.
How much should I bench?
It depends on your bodyweight, age, sex and how long you have trained. Compare yourself with your own past numbers first. If you compete, the Wilks, DOTS and IPF GL scores on our Wilks calculator let you compare lifters of different sizes fairly.
Does the bench press calculator work for dumbbells?
Yes. Choose Dumbbells and enter the weight of one dumbbell. You get your estimated dumbbell bench press max per hand. Dumbbell and barbell maxes are not the same, so do not double a dumbbell number to guess your barbell bench.
Is a paused bench max lower than touch-and-go?
For most lifters, yes, a little. Touch-and-go lets you use the bounce at the bottom, while a pause takes that away. If you compete in powerlifting, enter paused sets, because meets require a pause on the chest.
How accurate is a bench press 1RM calculator?
It is a good estimate, not an exact number. It works best from sets of 3 to 6 reps taken close to failure. Your real max can be a little higher or lower, so use the range shown under your result.
Can I use a high-rep set to find my bench max?
You can, but the estimate gets less reliable above 10 reps. A set of 15 or 20 depends a lot on endurance, which varies from person to person. For a better number, use a heavier set of 3 to 6 reps.
What is a bench PR calculator?
It is another name for a bench press 1RM calculator. It estimates your personal record for one rep from a set of several reps, so you can see a new PR without testing a true max.
How often can I test my bench press max?
Most lifters only need to test a true bench max at the end of a training block or before a meet. You can estimate it as often as you like from a heavy set, which is much easier to recover from.
