🧠 What is a Bench Press Calculator?

A bench press calculator is a simple online or offline tool that estimates how much weight you can lift for one maximum repetition (1RM) based on the number of reps and the weight you currently lift.

In other words, it helps you answer:

“If I can bench 225 lbs for 8 reps, what’s my 1 rep max?”

This is useful for planning workouts, setting goals, and understanding your strength level.

🔢 Top Bench Press Calculator Formulas (Used in 2025)

There are multiple formulas used by fitness coaches and lifters to estimate 1RM. Here are the top ones:

1️⃣ Epley Formula (Most Popular)

1RM = Weight × (1 + Reps ÷ 30)

Great for lower rep ranges (1–10 reps).

Example:
You bench 200 lbs for 5 reps.
→ 1RM = 200 × (1 + 5 ÷ 30) = 233.3 lbs

---

2️⃣ Brzycki Formula

1RM = Weight × 36 ÷ (37 − Reps)

More accurate for <10 reps.

Example:
You lift 150 lbs for 8 reps.
→ 1RM = 150 × 36 ÷ (37 − 8) = 186.2 lbs

---

3️⃣ Lombardi Formula

1RM = Weight × Reps^0.10

Good for advanced lifters doing higher reps.

---

4️⃣ O’Conner Formula

1RM = Weight × (1 + 0.025 × Reps)
