135, 225 and 315 are one, two and three 45 lb plates a side on a 45 lb bar; 185 is a plate and a 25.

A max-effort set for each rep count, from the Epley formula solved for the load: 1RM ÷ (1 + reps ÷ 30), rounded to 5 lb. These are all-out efforts, not work-set targets.

Enter the weight and reps of one hard bench set, in lb or kg, and this calculator gives your estimated one-rep max without maxing out. It also shows your bench-to-bodyweight ratio, your strength level among lifters your size and the next plate milestone. For a set of 3–8 reps, the bench estimate is usually within a few percent of a tested max.
What is my max bench from my reps?
Find your set below for a quick answer; the calculator gives the exact figure for any weight. Each number averages the Epley and Brzycki formulas, both close to tested bench maxes in validation work (LeSuer et al., 1997).
| Your set | 3 reps | 5 reps | 8 reps | 10 reps |
|---|---|---|---|---|
| 135 lb | 146 | 155 | 169 | 180 |
| 185 lb | 200 | 212 | 232 | 247 |
| 225 lb | 243 | 258 | 282 | 300 |
| 275 lb | 297 | 315 | 345 | 367 |
| 295 lb | 318 | 338 | 370 | 393 |
| 100 kg | 108 kg | 115 kg | 125 kg | 133 kg |
So 225x5 means a max of about 258 lb, and 295x5 about 338 lb.
How do you use the bench press calculator?
Enter the bar weight and the clean reps from your hardest recent set, then your bodyweight and sex for the comparison. Count only reps that touched your chest and locked out.
- Keep the set at 10 reps or fewer; past that, estimates drift because endurance takes over (Reynolds et al., 2006).
- Paused reps give a lower, more honest number than touch-and-go. In competition the bar must sit motionless on the chest before the press command (IPF Technical Rulebook).
- Use the same rep style every time, or your trend means nothing.
How accurate is a bench max calculator?
Very, compared with other lifts. In a classic validation study, most equations missed the tested bench by only 2.2–5.4 lb, and Epley's average miss was about 1%; deadlift estimates ran 9–14% low (LeSuer et al., 1997). Across 220 men, Brzycki was most accurate for sets of 10 or fewer, which is why the calculator averages it with Epley (Mayhew et al., 1995).
Is your bench max good for your bodyweight?
For a man, about 1.2 times bodyweight is intermediate: 220 lb at 180 lb, stronger than half of the lifters who log the lift; novice starts near 0.9 times and advanced near 1.5 (Strength Level). For a woman at 150 lb, intermediate is 114 lb. See the full bench press standards, with a table for 135 to 315.
How far is your next plate milestone?
Plate milestones count 45 lb plates per side on a 45 lb bar: 135 is one plate, 225 two and 315 three. In kilos the bar is 20 kg, so 60, 100 and 140 kg are one, two and three 20 kg plates (barbell).
See what percentage of men can bench 225 and how many people can bench 315 for how rare each is.
What if your bench estimate stops going up?
Three or four flat weeks means the bench has stalled, and the cause is usually not the bench itself: benching once a week, adding weight only when it feels easy, an untrained sticking point or dieting. Across 22 studies, strength gains rose from an effect size of 0.74 at one weekly session to 1.08 at four or more (Grgic et al., 2018). Run the bench press plateau check, or get the full diagnosis.
FAQ
How do I find my bench max without maxing out?
Do a hard set of 3–6 reps with a rep or two left, enter it here and use the average of the formulas. That is safer than a true single and usually within a few percent.
How many reps do I need to bench 135?
About 6 clean reps with 115 lb predicts a 135 max, and about 7 reps with 185 lb predicts 225.
Should I enter paused or touch-and-go reps?
Enter the style you train and test with, and keep it the same. Touch-and-go reps estimate a slightly higher max.
Why is my calculated bench higher than what I can lift?
Usually the set was not near failure or you rarely practice heavy singles. A few weeks of heavier triples and doubles closes the gap.
