RepolveGet the appIncline dumbbell press estimated 1RM calculator.
Estimate your incline dumbbell press one-rep max and compare your set with Repolve’s exercise standards. Enter the weight of one dumbbell—not the combined pair—to get a per-dumbbell estimate.
Calculate your incline dumbbell press score
Enter the weight of ONE dumbbell, not the combined pair. Use a completed set of 1–12 reps. Inputs stay in your browser.
A worked incline dumbbell press example
Two 25 kg dumbbells for 8 reps are entered as 25 kg. The estimated max is about 31.7 kg per dumbbell, or 0.40× an 80 kg bodyweight on this per-dumbbell scale. Entering 50 kg would double the input incorrectly.

Illustrative example using 80 kg bodyweight and male standards. Choosing female standards changes the exercise score, not the estimated max. This is one exercise score, not an overall Strength Score.
Incline Dumbbell Press rep-to-max examples
Each row uses a completed set at 25 kg per dumbbell. Enter the weight of ONE dumbbell, not the combined pair. These are formula examples, not suggested loads to attempt.
| Completed reps | Estimated 1RM per dumbbell |
|---|---|
| 1 | 25.0 kg |
| 3 | 27.5 kg |
| 5 | 29.2 kg |
| 8 | 31.7 kg |
| 10 | 33.3 kg |
| 12 | 35.0 kg |
A one-rep set uses the entered load. Sets of 2–12 reps use weight × (1 + reps ÷ 30). The result estimates a single repetition; it is not a guarantee that you can lift that weight.
Muscles worked
Chest, with front shoulders and triceps involved in the press. In Repolve’s scoring model, this exercise supplies primary evidence for chest. Training involvement and scoring coverage are different things.
Make your sessions comparable
Keep the bench angle and range of motion consistent. A steeper incline changes the movement, so note the setup in your history. Compare the same dumbbell weight convention from session to session.
How the estimate works
For a single rep, the estimate is the load entered. For 2–12 reps, the production engine uses the Epley estimate: weight × (1 + reps ÷ 30). It compares the resulting estimated max with bodyweight and the exercise’s sex-specific thresholds. This is an estimate from a completed set, not a prescription for your next attempt.
Incline Dumbbell Press strength standards
These ratios come directly from Repolve’s production standards. They describe exercise benchmarks, not population percentiles or age-adjusted rankings.
| Reference | Score | Male | Female |
|---|---|---|---|
| Beginner | 20 | 0.25× | 0.1× |
| Novice | 40 | 0.35× | 0.2× |
| Intermediate | 60 | 0.5× | 0.3× |
| Advanced | 100 | 0.65× | 0.45× |
| Elite | 125 | 0.85× | 0.6× |
Enter the weight of ONE dumbbell, not the combined pair. The same unit must be used for the lift and bodyweight. Understand the standards
Track progression
Progress may appear as more reps with the same dumbbells before you move to a heavier pair. Keep the actual reps next to the estimate and compare the same bench angle. This calculator gives you one snapshot. Repolve brings saved workouts, personal records, and eligible strength evidence together so you can understand exercise progress alongside your broader Strength Profile.

Common variations
Flat dumbbell bench press and incline barbell bench press use separate standards. Two 30 kg dumbbells belong in this form as 30 kg, not 60 kg. A barbell entry instead includes the full bar and plates.
Incline Dumbbell Press calculator questions
Do I enter one dumbbell or both?
Enter one dumbbell. If you press a pair of 25 kg dumbbells, use 25 kg, not 50 kg. The standards on this page use the same per-dumbbell convention.
Is the estimated 1RM for one dumbbell or both?
It is per dumbbell. A pair of 25 kg dumbbells for 8 reps gives an estimated 31.7 kg per dumbbell, not 31.7 kg for the pair. The table also uses per-dumbbell weight divided by your bodyweight.
Does the incline angle change the score?
The calculator does not take bench angle as an input. Keep your angle consistent and record setup changes, rather than treating results at different inclines as identical performances.

About this calculator
Written by Repolve to explain its own scoring model. Calculations and benchmark tables use the same engine and exercise standards as the app. Worked examples are illustrative, not customer results. Estimates describe logged performance; they do not directly measure muscle size or diagnose a training imbalance.
