What is CoC War Weight?

In Clash of Clans, "War Weight" is a hidden metric that the matchmaking system uses to pair clans against each other in Clan Wars. Essentially, it's a numerical value assigned to each component of your base, and the sum of these weights determines your base's overall contribution to your clan's war weight. The game's algorithm attempts to find opponents with a similar total war weight, aiming for fair matchups. Understanding and managing your war weight is crucial for competitive play. A base with high offensive power and low defensive weight (often called an "engineered" base) can manipulate matchmaking to gain an advantage. Conversely, a base with maximum defenses and weak offense will have a higher war weight and might face tougher offensive opponents. This CoC War Weight Calculator Spreadsheet is designed to help you estimate this value accurately.

Who should use it? Any Clash of Clans player participating in Clan Wars can benefit. This includes:

• Newer players trying to understand how their base impacts war.
• Mid-game players looking to optimize their progression path (e.g., balancing offense and defense).
• Advanced players and clan leaders aiming to strategize war weight management for the entire clan.
• Players considering "engineering" their base to gain a matchmaking advantage.

Common misconceptions:

• War Weight is only about defenses: This is false. While defenses contribute significantly, troops, spells, heroes, and even Clan Castle troops all factor into war weight. Offensive power is a major component.
• Maxing everything is always best for war: Not necessarily. For competitive wars, balancing offense (troops, heroes, spells) with defense is key. A severely under-leveled offense on a maxed defense can be a liability.
• Clan Castle weight is fixed: The weight of troops *in* your Clan Castle for defense during war contributes. Donating high-weight troops to your CC can increase your base's war weight.

This CoC War Weight Calculator Spreadsheet aims to demystify the complex calculations involved, providing a clear estimate.

CoC War Weight Formula and Mathematical Explanation

The exact formula used by Supercell is proprietary and can change over time. However, based on community analysis and observed behavior, a widely accepted approximation for a base's total war weight can be represented as follows:

Total War Weight = Defense Weight + Offensive Unit Weight

Where:

• Defense Weight: This is the sum of the weights of most buildings, including Walls, Traps, Hero Altars, and all defensive structures (Cannons, Archer Towers, etc.). Crucially, Army Camps, Resource Collectors, Resource Storages, and the Town Hall (especially at lower levels) contribute less or are sometimes excluded from this calculation by the community models. For simplicity in most calculators, a generalized "Defense Weight" is used, encompassing the primary defensive and structural elements.
• Offensive Unit Weight: This encompasses all trainable and usable offensive components. It's further broken down:
  • Trained Troop Weight: Sum of the weights of all troops you have trained (excluding those only available in the Clan Castle initially).
  • Spell Weight: Sum of the weights of all spells you can train.
  • Hero Weight: Sum of the weights of your Barbarian King, Archer Queen, Grand Warden, and Royal Champion.
  • Clan Castle Troop Weight: Weight of troops donated to your Clan Castle for war.
  • Siege Machine Weight: Weight of your unlocked Siege Machines.

Simplified Formula for Calculator: The calculator uses a more direct summation based on common community findings:

Total War Weight = DefenseWeight + TroopsWeight + SpellsWeight + HeroesWeight + ClanCastleWeight + SiegeMachinesWeight

This formula provides a good estimate for understanding your base's impact on war matchmaking.

Variables Table

Variable	Meaning	Unit	Typical Range (Illustrative)
Defense Weight	Sum of weights for Walls, Traps, Defenses, Hero Altars. Excludes some buildings like Storages, Collectors, Army Camps.	Points	~300,000 – 1,500,000+
Troop Weight (Trained)	Weight of all troops unlocked and trained. Varies significantly by troop level.	Points	~100,000 – 500,000+
Spell Weight	Weight of all spells unlocked and trained. Varies by spell level.	Points	~20,000 – 100,000+
Hero Weight	Combined weight of Barbarian King, Archer Queen, Grand Warden, Royal Champion based on level.	Points	~50,000 – 300,000+
Clan Castle Troop Weight	Weight of troops donated to the Clan Castle for war. High-level troops add significant weight.	Points	~10,000 – 80,000+
Siege Machine Weight	Weight of unlocked Siege Machines (Wall Wrecker, Battle Blimp, etc.).	Points	~10,000 – 40,000+
Total War Weight	Overall matchmaking value of the base.	Points	~600,000 – 2,500,000+

The ranges provided are highly approximate and depend heavily on Town Hall level and upgrade priorities. Use this CoC War Weight Calculator for precise estimations.

Practical Examples (Real-World Use Cases)

Let's illustrate with two distinct base scenarios using our CoC War Weight Calculator Spreadsheet.

Example 1: Maxed Defense, Balanced Offense (TH11)

Player 'Warrior' at Town Hall 11 has maxed defenses for their TH level, including walls and heroes (BK Lvl 50, AQ Lvl 50, GW Lvl 20). Their lab is focused on war troops and spells.

• Inputs:
  • Total Defense Weight: 750,000
  • Total Troop Weight (Trained): 250,000
  • Total Spell Weight: 70,000
  • Total Hero Weight: 200,000 (BK 50, AQ 50, GW 20)
  • Clan Castle Troop Weight: 40,000 (e.g., Max Golem + Wizards)
  • Siege Machine Weight: 25,000 (Unlocked: Wrecker, Blimp)
• Calculation:

  750,000 (Def) + 250,000 (Troops) + 70,000 (Spells) + 200,000 (Heroes) + 40,000 (CC) + 25,000 (Siege) = 1,335,000

• Outputs:
  • Primary Result (Total War Weight): 1,335,000
  • Intermediate Values: Defenses: 750,000, Units (Trained+CC): 290,000, Heroes & Siege: 225,000
• Interpretation: This base has a substantial war weight due to its heavily maxed defenses. While offensive capabilities are decent, the defense weight dominates. This base might face similarly weighted bases, potentially requiring strong offensive strategies to overcome enemy defenses. It's a solid, well-rounded war base but not designed for weight manipulation.

Example 2: "Engineered" Base (TH10) – High Offense, Lower Defense

Player 'Rusher' at Town Hall 10 has upgraded heroes significantly (BK Lvl 40, AQ Lvl 40) and focused heavily on unlocking and upgrading war troops and spells. They have deliberately kept some defenses (like some Air Defenses and Wizard Towers) at lower levels to reduce defensive weight.

• Inputs:
  • Total Defense Weight: 400,000 (Lower defenses, fewer walls)
  • Total Troop Weight (Trained): 300,000 (Max troops for TH10)
  • Total Spell Weight: 80,000 (Max spells for TH10)
  • Total Hero Weight: 250,000 (BK 40, AQ 40)
  • Clan Castle Troop Weight: 50,000 (Max Electro Dragon)
  • Siege Machine Weight: 30,000 (Unlocked all)
• Calculation:

  400,000 (Def) + 300,000 (Troops) + 80,000 (Spells) + 250,000 (Heroes) + 50,000 (CC) + 30,000 (Siege) = 1,110,000

• Outputs:
  • Primary Result (Total War Weight): 1,110,000
  • Intermediate Values: Defenses: 400,000, Units (Trained+CC): 350,000, Heroes & Siege: 280,000
• Interpretation: Despite being a TH10, this base has a significant war weight, comparable to a higher-level, more balanced base. This is driven by its extremely strong offensive potential (high heroes, max troops/spells). This "engineered" approach aims to face opponents with weaker offensive capabilities, allowing for easier three-star attacks. However, defending against higher Town Hall levels can be challenging. This CoC War Weight Calculator helps quantify this imbalance.

How to Use This CoC War Weight Calculator

Using our CoC War Weight Calculator Spreadsheet is straightforward. Follow these steps to get an accurate estimate of your base's war weight and understand its components.

1. Gather Your Base Information:
   • Defenses: You need the approximate *total weight* of all your defenses. This includes Walls, Traps (Bombs, Springs, etc.), Hidden Teslas, Air Mines, Skeleton Traps, Bomb Towers, Archer Towers, Cannons, Wizard Towers, Inferno Towers, Eagle Artillery, Scattershots, X-Bows, and Hero Altars. Exclude Army Camps, Resource Storages, Resource Collectors, Laboratory, and Spell Factory from this specific input. You can find approximate individual building weights online or in community resources. Sum them up.
   • Troops: Sum the weights of all your *trained* troops (excluding those you only have in your Clan Castle). This usually means troops from your Barracks, Dark Barracks, and Pet House.
   • Spells: Sum the weights of all your *trained* spells (Elixir and Dark Elixir spells).
   • Heroes: Sum the weights associated with your Barbarian King, Archer Queen, Grand Warden, and Royal Champion based on their current levels.
   • Clan Castle Troops: Estimate the weight of the troops typically donated to your Clan Castle for war. High-level troops add significant weight here.
   • Siege Machines: Sum the weights of all Siege Machines you have unlocked.

   Tip: Many online CoC resources and forums provide tables with approximate weights for buildings, troops, spells, and heroes at different levels.

2. Input Values into the Calculator: Enter the collected weights into the corresponding fields in the calculator above. Use the helper text below each input for guidance on what to include. Ensure you enter numerical values only.
3. Calculate: Click the "Calculate War Weight" button. The calculator will process your inputs.
4. Interpret the Results:
   • Primary Result: This is your estimated total war weight. A higher number generally means you'll face heavier opponents in war.
   • Intermediate Values: These show the breakdown – how much weight comes from your defenses, your offensive units (trained troops, heroes, CC troops, spells, siege machines), and heroes/siege machines specifically. This helps identify where your base's weight is concentrated.
   • Table Breakdown: The table provides a detailed percentage and weight distribution for each component, offering a clear visual of your base's composition.
   • Chart: The chart visualizes this distribution, making it easy to see which component contributes the most to your total war weight.
5. Decision-Making Guidance:
   • High Defense Weight, Low Offense: You might struggle to get 3 stars against opponents, but your base might be hard to 3-star. Consider focusing on offensive upgrades (heroes, troops, spells) to balance.
   • Low Defense Weight, High Offense: You'll likely achieve 3 stars easily against similarly matched opponents, but your base might be easier to 3-star. This is typical of "engineered" bases. Ensure your clan is comfortable with this strategy.
   • Balanced Weight: Your base is well-rounded, contributing a moderate war weight. This is often a good strategy for players who want to contribute both offensively and defensively without extreme manipulation.
6. Reset and Experiment: Use the "Reset" button to clear fields and try different scenarios. For instance, see how upgrading a specific defense or troop impacts your total weight. The "Copy Results" button is useful for sharing your analysis or saving it elsewhere.

Key Factors That Affect CoC War Weight Results

Several factors influence your base's war weight calculation. Understanding these can help you strategically manage your base progression for optimal Clan War performance. This CoC War Weight Calculator relies on these inputs.

1. Defense Levels: This is arguably the most significant contributor to war weight. Upgrading defenses like Inferno Towers, Eagle Artillery, X-Bows, and even basic Cannons and Archer Towers increases your defense weight substantially. Maxing defenses usually results in a very high war weight.
2. Hero Levels: Your Barbarian King, Archer Queen, Grand Warden, and Royal Champion contribute heavily, especially at higher levels. Prioritizing hero upgrades is essential for both offense and war weight. The combined weight of maxed heroes at higher Town Halls is considerable.
3. Troop and Spell Levels: While often considered "offense," the levels of your troops and spells directly impact war weight. Maxing out your primary war troops (e.g., Dragons, Electro Dragons, Yetis, Witches) and key spells (e.g., Rage, Freeze, Poison) significantly boosts your offensive unit weight. Investing in the Laboratory upgrades is critical.
4. Walls: While they don't defend directly, upgraded walls add a notable amount to the total defense weight. Players often delay maxing walls if they are focusing on offense or trying to keep weight low, but they are a key component of a high-weight base.
5. Clan Castle Troops: The specific troops donated to your Clan Castle for war defense carry weight. Donating high-level, computationally "heavy" troops (like Electro Dragons or Super Troops) can noticeably increase your base's overall war weight. This is a flexible component you can adjust.
6. Siege Machines: Each unlocked Siege Machine adds its own weight. While individually less impactful than max defenses or heroes, collectively they contribute to the offensive component of your war weight. Unlocking them is part of progressing in the game and impacts war readiness.
7. Town Hall Level: While not a direct input in this calculator, your Town Hall level fundamentally dictates the maximum levels for defenses, troops, heroes, and spells. Higher Town Hall levels inherently allow for much higher potential war weights due to access to more powerful upgrades and buildings. Our Town Hall Upgrade Planner can help visualize this.
8. Unused Potential (Offense): Even if you don't use certain troops or spells frequently, if they are unlocked and upgraded, they contribute to your overall war weight. This is a subtle factor that contributes to the "engineered" base concept – maximizing offensive weight while minimizing defensive weight. A base that has fully upgraded offensive capabilities but lower defenses will appear "heavier" offensively than defensively.

Frequently Asked Questions (FAQ)

Q1: How accurate is this CoC War Weight Calculator?

This calculator provides a highly accurate *estimate* based on widely accepted community formulas. Supercell's exact algorithm is not public and can be adjusted. However, for practical war strategy and understanding matchmaking trends, this tool is very effective.

Q2: Should I try to engineer my base to lower my war weight?

Engineering (prioritizing offense over defense) can provide a matchmaking advantage, potentially allowing you to face weaker opponents offensively. However, it also makes your base harder to defend. Whether it's "worth it" depends on your clan's strategy, your playstyle, and the competitive environment. Use this CoC War Weight Calculator to analyze the trade-offs.

Q3: Does the Town Hall itself add weight?

Traditionally, the Town Hall's weight contribution varied significantly by level and was often considered low compared to defenses or heroes. Some models exclude it or give it minimal weight. Our calculator focuses on the core components widely agreed upon to influence matchmaking.

Q4: What about Resource Storages and Collectors? Do they add weight?

Resource Storages and Collectors generally add very little to no war weight in most community models. They are typically excluded from the "Defense Weight" calculation as they are not defensive structures.

Q5: How do troop levels affect weight more than defense levels?

This isn't universally true. Maxed defenses at higher Town Halls often contribute more raw weight than maxed troops. However, the *progression curve* can differ. A player might max their offense (troops, spells, heroes) faster than their defenses, leading to a disproportionately high offensive weight relative to their defensive weight for their Town Hall level. This calculator helps quantify that balance.

Q6: Can I "hide" war weight by not upgrading certain things?

Yes, this is the core principle of engineering. By delaying upgrades on certain defenses or non-essential structures, you keep your total war weight lower. However, you sacrifice defensive strength. This CoC War Weight Calculator quantifies exactly how much weight each component adds.

Q7: What is the weight of a specific troop or spell?

Exact weights vary per troop/spell and level. This calculator requires the *sum* of weights for all your troops and spells. You'll need to consult external CoC resources or community wikis for specific unit weights to calculate your totals accurately.

Q8: Does the calculator account for Pet Levels?

As of recent updates, Pets also contribute to offensive weight. While not explicitly a separate input in this simplified calculator, their weight is generally captured within the broader "Troop Weight" or "Hero Weight" categories depending on how community resources categorize them. For maximum accuracy, ensure your troop/hero weight inputs reflect all available offensive unit upgrades.
