What is an Axis and Allies Calculator 1940?
The axis and allies calculator 1940 is a specialized tool designed for the “Axis & Allies Global 1940” board game, including the Europe and Pacific 1940 theater editions. Unlike basic dice rollers, this calculator accounts for the unique unit interactions introduced in the 1940 ruleset, such as combined arms and tactical bomber synchronization. Using an axis and allies calculator 1940 allows players to move beyond guesswork and understand the mathematical probability of a successful offensive or a sturdy defense.
Serious players use an axis and allies calculator 1940 to decide whether to commit expensive units like strategic bombers or fighters to a battle. Because the game relies on d6 (six-sided dice) mechanics where lower rolls are hits, the statistical variance can be high. This tool provides the “Expected Value” (EV) of hits, which is the average number of units you should expect to destroy in a single round of combat.
A common misconception is that having more units always guarantees victory. However, an axis and allies calculator 1940 proves that quality and combined arms bonuses often outweigh sheer numbers. For instance, four infantry attacking alone are statistically weaker than two infantry paired with two artillery, despite the unit count being identical.
Axis and Allies Calculator 1940 Formula and Mathematical Explanation
The math behind the axis and allies calculator 1940 is based on probability theory. Each unit has a “Hit Threshold.” For example, a Tank attacks at 3, meaning a roll of 1, 2, or 3 on a d6 results in a hit. This represents a 50% success rate per die.
The core formula for Expected Hits (EH) is:
EH = Σ (Quantity of Unit × (Hit Threshold / 6))
| Variable (Unit) | Attack Value | Defense Value | Special Condition |
|---|---|---|---|
| Infantry | 1 (or 2) | 2 | +1 Att with Artillery |
| Artillery | 2 | 2 | Supports 1 Inf/Mech |
| Tank | 3 | 3 | Pairs with Tac Bomber |
| Tactical Bomber | 3 (or 4) | 3 | +1 Att with Tank/Fighter |
| Fighter | 3 | 4 | Highest defensive value |
Practical Examples (Real-World Use Cases)
Example 1: The Invasion of France
Suppose the German player attacks France with 6 Infantry, 2 Artillery, and 2 Tanks. The French defender has 4 Infantry and 1 Fighter. By entering these into the axis and allies calculator 1940, we find:
- Attacker Hits: (2 Inf * 1/6) + (4 Inf * 2/6) + (2 Art * 2/6) + (2 Tanks * 3/6) = 0.33 + 1.33 + 0.66 + 1.0 = 3.32 expected hits.
- Defender Hits: (4 Inf * 2/6) + (1 Fight * 4/6) = 1.33 + 0.66 = 1.99 expected hits.
The axis and allies calculator 1940 shows the attacker will likely clear the territory in 2 rounds while losing about 4 infantry.
Example 2: Pacific Fleet Engagement
A Japanese fleet with 2 Fighters and 1 Tactical Bomber attacks a US Destroyer and Carrier. While the US has fewer units, the axis and allies calculator 1940 highlights that the US Fighter’s defense of 4 is a major hurdle, requiring the Japanese player to bring more “punch” to ensure the Carrier is sunk before Japanese air assets are lost.
How to Use This Axis and Allies Calculator 1940
- Enter Attacker Units: Fill in the number of each unit type currently launching the assault. Note the “helper text” for combined arms bonuses.
- Enter Defender Units: Fill in the units stationed in the territory or sea zone being defended.
- Review the Primary Result: The “Projected Outcome” will update in real-time, indicating “Attacker Advantage,” “Defender Advantage,” or “Neutral.”
- Analyze Intermediate Values: Look at the “Expected Hits” per side. If the Attacker EH is double the Defender EH, a wipe is likely.
- Check the Chart: Use the SVG power bars to visually compare the raw “dice weight” of both forces.
Key Factors That Affect Axis and Allies Calculator 1940 Results
- Artillery Pairing: In the 1940 rules, each artillery unit increases one infantry’s attack from 1 to 2. This is the most efficient way to boost offensive power.
- Tactical Bomber Synergy: Pairing a Tactical Bomber with a Tank or Fighter increases its attack to 4. Without this, it’s just a more expensive Fighter on offense.
- Defense Bias: Defense is generally “cheaper” in Axis and Allies. Infantry defending at 2 are much more cost-effective than infantry attacking at 1.
- Air Superiority: Fighters and Bombers provide massive punch but cannot take territories alone. The axis and allies calculator 1940 helps you balance “soaking” units (infantry) with “hitting” units (planes).
- The “Luck” Factor: While the calculator provides the statistical mean, dice variance (getting “dicey”) can still swing a battle. Always aim for a force ratio of at least 1.5 to 1 in your favor.
- Order of Loss: The calculator assumes optimal play where players lose their cheapest units first (usually infantry) to preserve their “punch.”

Frequently Asked Questions (FAQ)
Q: Does this axis and allies calculator 1940 include AAA guns?
A: This version focuses on standard combat rounds. AAA guns fire once before regular combat and are not included in the ongoing EH calculation.
Q: How does the calculator handle Mech Infantry?
A: Mechanized Infantry are treated like standard Infantry in combat but are calculated separately to ensure they receive Artillery bonuses correctly.
Q: What is a “good” win probability in Axis and Allies?
A: Most veterans consider an 80% or higher win chance (or an EH ratio of 1.5+) as a safe “go” for a major offensive.
Q: Why is my Strategic Bomber defense only 1?
A: In the 1940 edition rules, Strategic Bombers were nerfed on defense to 1 to represent their vulnerability to interceptors and lack of maneuverability.
Q: Can tactical bombers get a bonus from mechanized infantry?
A: No, tactical bombers only get the +1 attack bonus when paired with a Tank or a Fighter in the 1940 ruleset.
Q: Does terrain affect the axis and allies calculator 1940 results?
A: The 1940 base rules do not have terrain modifiers, though some house rules do. This calculator follows the official Out-of-the-Box (OOB) rules.
Q: How are hits rounded?
A: We show the raw decimal (Expected Value). In practice, you cannot have 2.5 hits, but over 100 battles, you would average exactly that.
Q: Is this calculator compatible with the 1942 Second Edition?
A: While the core d6 mechanics are similar, the 1940 edition has different unit costs and tactical bomber mechanics, so this specific axis and allies calculator 1940 is optimized for the 1940 game versions.
