Arrow Drop Calculator

Calculate arrow drop instantly with our free online Arrow Drop Calculator. Perfect for bows and crossbows. Accurate, fast, and easy to use.

When you shoot an arrow, gravity starts working on it the moment it leaves the bow. The arrow doesn’t travel in a straight line forever it drops over distance. Understanding this drop is critical whether you're bowhunting, shooting a compound bow, or using a crossbow. That’s why we developed the Arrow Drop Calculator a simple and accurate tool that helps you calculate how much your arrow will drop based on speed, distance, and angle.

Our tool is designed for beginners and professionals alike. With an intuitive interface and instant results, you’ll never have to guess how much your arrow will fall again.

What is Arrow Drop?

Arrow drop is the vertical distance an arrow falls from the line of sight during its flight. As the arrow travels forward, gravity pulls it downward. The farther the arrow travels, the more it drops. This phenomenon is influenced by the arrow's speed, the shooting distance, gravity, and the angle at which the arrow is released.

Knowing your arrow's drop helps you adjust your aim and ensures greater accuracy. Whether you’re shooting at 20 yards or 60 yards, understanding this drop is key to hitting your target every time.

How the Arrow Drop Calculator Works

Our Arrow Drop Calculator uses physics-based projectile motion formulas to calculate drop. We offer two modes:

Simple Calculation (For Flat Shots)

This mode is for arrows shot straight or nearly flat.

Formula:

Drop = 6 × g × d² ÷ v²

Where:

  • g = gravity (usually 32.2 ft/s²)
  • d = distance to target (in feet)
  • v = arrow speed (in ft/s)

This gives the drop in inches.

Precise Calculation (For Angled Shots)

This is for arrows launched at a specific angle. It accounts for vertical motion and flight arc.

Formula:

Drop = x × tan(θ) - (g × x²) ÷ (2 × v² × cos²(θ))

Where:

  • x = distance to target (in feet)
  • θ = launch angle (in degrees)
  • v = arrow speed (in ft/s)
  • g = gravity (32.2 ft/s²)

This gives a more realistic drop based on arrow trajectory.

How to Use the Arrow Drop Calculator

Using the calculator is simple and takes just a few seconds:

Step 1:

Enter your arrow speed. You can use units like fps (feet per second), mps (meters per second), km/h, or mph.

Step 2:

Enter the distance to your target. Units can be in feet, meters, yards, or inches.

Step 3:

Select the gravity value. The default is Earth’s gravity (32.2 ft/s²).

Step 4:

Choose your calculation method – Simple (flat shot) or Precise (angled shot). If choosing Precise, enter the launch angle in degrees.

Step 5:

Click “Calculate.” You’ll instantly see the arrow’s drop in inches, time of flight, and even peak height if using the precise method.

This tool is perfect for archers using compound bows, recurve bows, and crossbows.

Final Verdict

If you're serious about improving your archery or hunting accuracy, you need to know exactly how your arrows behave in flight. The Arrow Drop Calculator is your perfect digital assistant. Whether you're tracking arrow ballistics for compound bows or figuring out crossbow trajectory, this tool removes all the guesswork.

With real-time calculations, support for multiple units, and clear results, it's the best arrow drop calculator for shooters of all skill levels. Try it today and take the mystery out of arrow flight.

FAQs

How much does an arrow drop at 40 yards?

The drop depends on arrow speed. For example, with a speed of 280 fps and a 40-yard distance, the drop is around 15–20 inches. Use our calculator for an exact result based on your setup.

Is this calculator accurate for crossbows?

Yes. Crossbow arrow speeds are usually higher, but our calculator supports both compound bows and crossbows accurately.

Can I use this for 3D archery or hunting?

Absolutely. Knowing your arrow’s drop helps you aim more precisely during 3D competitions and real-life hunts.

What is the best arrow drop calculator?

This one. We’ve developed it using accurate physics formulas and real-world testing for all archery styles.

Do I need to include air resistance?

This calculator currently assumes no air resistance, which is fine for short to medium distances. For long-range ballistics, you may need advanced tools with drag modeling.
