How To Calculate Your 1RM With A Calculator
Here is how to use a one rep max calculator to estimate your one rep max.
Although this is not as accurate as actually lifting your 1 rep max, it is a safer approach.
As an example, let’s say you lifted 225 lbs and failed at 5 reps on the barbell flat bench press.
Now that you know this, it’s time to quickly input this data into the free one rep max calculator on our website.

How To Use The One Rep Max Calculator
- Input how much weight you lifted, in pounds or kilograms, in the “Weight” field.
- In this example, you lifted 225 lbs.
- Select how many reps you completed with proper form from the “Reps” dropdown box.
- In this example, you completed 5 reps.
- Click the “Calculate” button to get your 1 rep max amount and percentage calculations.
- In this example, your estimated 1 rep max is 253 lbs.
Since this is just an estimate, and the goal is to get stronger in a safe manner, I recommend you round the numbers down.
Based on this calculation, your 1 rep max would be 250 lbs on the barbell flat bench press.
