What is a PUBG Mortar Calculator?
A PUBG mortar calculator is a specialized tool designed to help players in the popular battle royale game PlayerUnknown’s Battlegrounds (PUBG) determine the optimal firing parameters for mortar weapons. Mortars in PUBG are indirect fire weapons, meaning they don’t fire directly at the target but follow an arcing trajectory influenced by gravity and air resistance. Calculating this trajectory manually can be complex and time-consuming, especially under pressure during a match. This is where a PUBG mortar calculator becomes invaluable. It takes key input variables such as muzzle velocity, shell weight, target distance, and firing angle, and provides precise outputs like the shell’s flight time, maximum height, impact point, and optimal launch angle. By using this calculator, players can significantly improve their accuracy with mortars, effectively hitting stationary or moving targets from a distance, even when line of sight is obstructed. It’s a critical tool for strategic players aiming to master indirect fire.
Who should use it?
Any PUBG player who wants to effectively utilize mortars. This includes:
- Squad leaders coordinating indirect fire support.
- Players engaging enemies behind cover or at long distances.
- Competitive players seeking an edge in tactical engagements.
- New players looking to understand mortar ballistics better.
Common misconceptions about mortars and their use often involve assuming simpler, linear trajectories or ignoring the significant impact of air resistance. Many players also underestimate the importance of precise angle adjustments for different ranges. A PUBG mortar calculator helps dispel these myths by providing data-driven insights.
PUBG Mortar Calculator Formula and Mathematical Explanation
The physics governing a mortar shell’s flight are complex, primarily involving projectile motion with air resistance (drag). While simplified physics equations can estimate range, a more accurate PUBG mortar calculator often employs numerical methods to simulate the trajectory step-by-step.
The core principles involve:
- Initial Conditions: The shell is launched with an initial velocity ($v_0$) at an angle ($\theta$) relative to the horizontal.
- Forces Acting on the Shell:
- Gravity (Fg): Acts downwards, $Fg = m \cdot g$, where $m$ is mass and $g$ is acceleration due to gravity (approx. 9.81 m/s²).
- Air Resistance (Fd): Acts opposite to the direction of motion. It depends on the shell’s velocity ($v$), air density ($\rho$), drag coefficient ($C_d$), and cross-sectional area ($A$). The formula is typically $Fd = 0.5 \cdot \rho \cdot v^2 \cdot C_d \cdot A$.
- Equations of Motion: Using Newton’s second law ($F=ma$), we can derive differential equations for acceleration in the x (horizontal) and y (vertical) directions.
- $a_x = -\frac{Fd_x}{m}$
- $a_y = -g – \frac{Fd_y}{m}$
Where $Fd_x$ and $Fd_y$ are the components of the drag force.
- Numerical Integration: Because the drag force depends on velocity squared, the equations of motion become non-linear and difficult to solve analytically for exact range. Numerical methods like Euler integration (or more advanced ones like Runge-Kutta) are used. In simple Euler integration:
- Update velocity: $v_{new} = v_{old} + a \cdot \Delta t$
- Update position: $p_{new} = p_{old} + v_{old} \cdot \Delta t$ (or using updated velocity for better accuracy)
This process is repeated for small time steps ($\Delta t$) until the shell hits the ground ($y \le 0$).
Variable Explanations
The calculator uses the following variables:
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| Muzzle Velocity ($v_0$) | The initial speed of the mortar shell as it leaves the barrel. | m/s | 150 – 300 |
| Shell Weight ($m$) | The mass of the mortar projectile. | kg | 2.0 – 10.0 |
| Drag Coefficient ($C_d$) | A dimensionless number representing how aerodynamically resistant an object is. | Unitless | 0.1 – 0.5 (approx. 0.3 for spheres) |
| Shell Diameter ($d$) | The diameter of the mortar shell, used to calculate its cross-sectional area ($A = \pi (d/2)^2$). | m | 0.05 – 0.15 |
| Elevation Angle ($\theta$) | The angle at which the mortar is fired relative to the horizontal ground. | degrees | 10 – 85 |
| Target Horizontal Distance ($x_{target}$) | The direct horizontal distance from the mortar to the intended target. | m | 50 – 1000+ |
| Gravity ($g$) | Acceleration due to Earth’s gravity. | m/s² | ~9.81 (Constant) |
| Air Density ($\rho$) | Density of the air, affects drag force. Varies with altitude and temperature. | kg/m³ | ~1.225 (Sea level standard) |
| Time Step ($\Delta t$) | Small increment of time used in numerical integration. | s | 0.01 – 0.05 (typical) |
Practical Examples (Real-World Use Cases)
Example 1: Engaging a Static Target
A player spots an enemy team dug into a small bunker approximately 600 meters away. The terrain is relatively flat.
Inputs:
- Muzzle Velocity: 250 m/s
- Shell Weight: 4.0 kg
- Drag Coefficient: 0.3
- Shell Diameter: 0.081 m
- Target Horizontal Distance: 600 m
- Elevation Angle: 48 degrees (Initial guess)
Calculation Process: The PUBG mortar calculator is used. An initial angle of 48 degrees is entered. The calculator simulates the trajectory. Let’s say the simulation shows the shell landing 50 meters short (at 550m). The user then increases the elevation angle to, for example, 52 degrees and recalculates. This time, the calculator predicts the shell will land at the target distance of 600 meters.
Outputs:
- Optimal Launch Angle: 52 degrees
- Estimated Time of Flight: 12.5 seconds
- Maximum Height: ~780 meters
- Impact Point: 600 meters horizontal distance
Interpretation: The player now knows to set their mortar to a 52-degree angle to accurately hit the bunker 600 meters away. The high flight time suggests the enemy team has ample warning, so speed is important.
Example 2: Hitting a Moving Target
A player sees an enemy vehicle driving across an open field towards a compound, approximately 400 meters away. The vehicle is moving perpendicular to the player’s line of sight at an estimated speed of 60 km/h (approx. 16.7 m/s).
Inputs:
- Muzzle Velocity: 230 m/s
- Shell Weight: 3.0 kg
- Drag Coefficient: 0.3
- Shell Diameter: 0.081 m
- Target Horizontal Distance: 400 m
- Elevation Angle: 45 degrees (Initial guess)
Calculation Process: First, the calculator is used with the base parameters to find the landing spot for a stationary target at 400m with a 45-degree angle. Let’s assume this gives a time of flight of 9.8 seconds. The player then calculates the distance the vehicle will travel during this time: $Distance = Speed \times Time = 16.7 \, m/s \times 9.8 \, s \approx 164 \, meters$. This means the shell fired directly at the vehicle’s current position will miss. The player needs to lead the target. They must adjust their aim so the shell lands 164 meters *ahead* of the vehicle’s current position along its path. If the mortar has a maximum range of, say, 500m at 45 degrees, the player might need to fire at a point 400m + 164m = 564m ahead, which exceeds the mortar’s range. In this scenario, the player might need to use a higher angle (if possible) or a different mortar type. Alternatively, they might aim for a point 400m away but slightly offset laterally if the vehicle’s path allows for a flanking shot. For this example, let’s assume the vehicle is moving towards the player, and they need to calculate the impact point at 400m. The calculator’s primary output confirms the 400m range is achievable. The player now needs to estimate where the vehicle will be in 9.8 seconds and aim accordingly.
Outputs:
- Base Time of Flight (at 400m): 9.8 seconds
- Target Lead Distance (if moving across): ~164 meters
Interpretation: The player understands that simply aiming at the vehicle isn’t enough. They must anticipate its movement. For a target moving directly towards them, the 400m range might be sufficient. For a target moving laterally, they’d need to adjust their aim point significantly forward. This highlights the need to combine PUBG mortar calculator data with real-time observation.
How to Use This PUBG Mortar Calculator
Using this PUBG mortar calculator is straightforward and designed to be quick, even in the heat of battle. Follow these steps:
-
Gather Input Data:
- Muzzle Velocity: Check your in-game mortar’s stats or use a common value (around 230-250 m/s is typical for 81mm mortars).
- Shell Weight: Similar to muzzle velocity, check your mortar’s specific shell.
- Drag Coefficient & Diameter: These are often standardized for common shell types (like a sphere). Use the default values provided (Cd ~0.3, Diameter ~0.081m for 81mm).
- Target Horizontal Distance: Use your in-game rangefinder, minimap estimate, or any other method to determine the distance to your target.
- Elevation Angle: This is the crucial variable you’ll often adjust. Start with a common angle like 45 degrees or use the calculator’s suggested angle if it has a “find angle for range” feature (this calculator uses a fixed angle input for simplicity but shows results for it).
- Enter Values: Input the gathered data into the respective fields on the calculator. Ensure you enter accurate numbers for the best results. Pay attention to the units (meters, seconds, kilograms, degrees).
- Calculate Trajectory: Click the “Calculate Trajectory” button. The calculator will process the inputs and display the results.
-
Read the Results:
- Primary Result: This shows the predicted range achieved with the entered Elevation Angle. Compare this to your Target Horizontal Distance.
- Intermediate Values: Note the Launch Angle (used for the primary result), Max Height (useful for understanding the arc), Time of Flight (how long the shell takes to land), and Impact Velocity.
- Trajectory Table & Chart: These visualizations provide a point-by-point breakdown of the shell’s path and a graphical representation, helping you visualize the arc.
-
Adjust and Refine:
- If the predicted range is shorter than your target distance, you need to increase the Elevation Angle.
- If the predicted range is longer, you need to decrease the Elevation Angle.
- Enter a new Elevation Angle and click “Calculate Trajectory” again. Repeat until the calculated range closely matches your Target Horizontal Distance.
- Apply in Game: Once you find an Elevation Angle that achieves the desired range, set your in-game mortar to that angle and fire. Remember to account for target movement, especially for vehicles or running players. Use the Time of Flight to estimate where a moving target will be.

Mastering the PUBG mortar calculator takes practice, but it dramatically increases the effectiveness of this powerful weapon system.
Key Factors That Affect PUBG Mortar Results
Several factors influence the accuracy and effectiveness of mortar fire in PUBG. Understanding these is crucial for successful indirect engagements:
- Elevation Angle: This is the most direct control a player has. A higher angle generally results in a longer range, up to an optimal point (typically around 45 degrees in vacuum, but affected by drag), after which range decreases. Precise adjustment is key.
- Muzzle Velocity: A higher muzzle velocity means the shell leaves the barrel faster, resulting in a longer range and flatter trajectory (less drop over distance). Different mortars or ammunition types in PUBG might have varying muzzle velocities.
- Target Distance: The further the target, the more pronounced the effects of gravity and air resistance become. Calculating the correct angle for long distances is far more critical than for close targets.
- Air Resistance (Drag): This is a significant factor often simplified or ignored. Factors like shell shape (drag coefficient), size (cross-sectional area), and speed influence how much the air slows the shell down. A heavier, more aerodynamic shell will travel further and be less affected by drag. Our PUBG mortar calculator accounts for this.
- Wind: While not explicitly modeled in most simple calculators or directly in PUBG’s core mechanics for mortars, strong winds could theoretically affect shell drift, especially over long distances. In PUBG, this is usually less of a factor than other variables.
- Target Movement: This is critical for practical application. The PUBG mortar calculator provides the trajectory for a *static* point. Players must estimate the target’s speed and direction and “lead” their shot accordingly, aiming ahead of the target’s predicted position based on the shell’s time of flight.
- Terrain and Obstacles: Mortars are indirect fire weapons, allowing them to shoot over obstacles. However, the calculator assumes a clear path. Players must ensure their target is not blocked by intermediate terrain features or buildings, and that the shell’s apex is high enough to clear any intervening cover.
- Shell Type/Weight: Different ammunition types (if available for a specific mortar) will have different weights and aerodynamic properties, directly impacting range and trajectory. The calculator allows inputting shell weight.
Frequently Asked Questions (FAQ)
Q1: How accurate is this calculator compared to in-game results?
This calculator uses physics-based models that closely approximate real-world ballistics and the likely mechanics within PUBG. However, in-game physics can sometimes have simplifications or unique implementations. Factors like wind (often not explicitly modeled in game but present in real life) or slight variations in shell properties might cause minor discrepancies. It provides a highly accurate estimate and a strong starting point.
Q2: What is the standard mortar type and shell in PUBG?
The most common mortar is the 81mm Mortar. Standard 81mm shells are roughly spherical or fin-stabilized. The default values in this calculator (Muzzle Velocity ~240 m/s, Shell Weight ~3.5 kg, Diameter ~0.081 m, Cd ~0.3) are representative of typical 81mm mortar rounds.
Q3: Can I use this calculator for other projectile weapons in PUBG?
Primarily, this calculator is optimized for mortars due to their specific indirect fire characteristics (high arc, significant drop). It may not be accurate for direct-fire weapons like sniper rifles or rockets, which follow different ballistic paths.
Q4: How do I account for moving targets?
Use the calculated “Time of Flight” from the calculator. Estimate the target’s speed and direction. Multiply the speed by the time of flight to determine how far the target will move. Aim your mortar ahead of the target’s current position by that calculated distance (this is called “leading” the target). This requires practice and real-time judgment.
Q5: What does the “Drag Coefficient” mean?
The Drag Coefficient ($C_d$) is a measure of how much air resistance affects an object. A lower $C_d$ means the object is more aerodynamic and experiences less drag. A value of 0.3 is typical for a sphere. This impacts how quickly the shell slows down in flight, affecting range and trajectory.
Q6: My calculated range is much shorter than expected. What should I check?
Ensure your “Target Horizontal Distance” is entered correctly. Double-check the “Muzzle Velocity” and “Elevation Angle.” If your target is very close, a high elevation angle might actually decrease the range because the shell goes too high and comes down too steeply. Try slightly lower angles for closer targets.
Q7: Does altitude affect the calculation?
In real-world physics, air density decreases with altitude, reducing air resistance and potentially increasing range. Standard PUBG maps are generally at sea level or moderate altitudes. This calculator uses a standard sea-level air density (~1.225 kg/m³). Significant altitude differences are not usually a primary concern for most PUBG maps, but could be a minor factor.
Q8: How do I input different mortar types if they have different stats?
Simply update the “Muzzle Velocity”, “Shell Weight”, and potentially “Shell Diameter” fields to match the stats of the specific mortar you are using in PUBG. If you don’t know the exact stats, using the default values provides a good approximation for common mortar types.
