What is Calculate War Weight?
In the competitive landscape of Clash of Clans, the ability to accurately calculate war weight is a fundamental skill for serious clan leaders and strategists. War weight is a hidden numerical value assigned by the game's matchmaking algorithm to every base in a clan war. This value represents the defensive and offensive strength of a player's village. The sum of all individual war weights in a clan determines the "Total Clan Weight," which the server uses to find an opponent clan of similar strength.
Knowing how to calculate war weight helps players optimize their upgrade paths. By understanding which upgrades add the most weight versus the most utility, players can "engineer" their bases to offer lower defensive weight while maintaining high offensive power. This strategy, often referred to as ".5" bases (like TH9.5 or TH10.5), aims to secure easier matchups for the clan. Common misconceptions include the belief that walls calculate war weight heavily or that traps add zero weight; in reality, every element contributes, but weighted differently.
Calculate War Weight Formula and Mathematical Explanation
While the exact server-side algorithm is proprietary to Supercell, the community has derived a highly accurate approximation to calculate war weight. The core method involves analyzing the Gold available in storages during a war (Battle Day), as this value is directly correlated to the defensive weight.
The formula to calculate war weight typically breaks down into three core components: the Base Floor (Town Hall), the Heavy Defense Penalty (Eagle, Infernos, Scattershots), and the Hero Factor.
Consider a player who just upgraded to Town Hall 13. They want to calculate war weight to decide if they should drop the Royal Champion immediately.
Current Weight: 110,000 (Max TH12 weight).
Proposed Upgrade: Add Royal Champion (Level 1) and Scattershots (Level 1).
Calculation: The Scattershots are extremely heavy. Adding two Scattershots might increase weight by roughly 4,000 points, pushing the total to 114,000.
Decision: If the player's offensive troops are not yet upgraded to TH13 levels, adding 4,000 defensive weight might match the clan against a stronger opponent that they cannot 3-star. They delay the Scattershots.
Example 2: The Engineered Rushed Base
A "rushed" TH16 has maxed offense (Electro Dragons and Heroes) but TH11-level defenses.
Output: The calculator might show a weight of 125,000.
Comparison: A fully maxed TH16 would calculate war weight at roughly 160,000+.
Result: This base draws a TH14 or TH15 opponent in war but attacks with TH16 power, creating a mismatch advantage.
How to Use This Calculate War Weight Calculator
Follow these steps to utilize the tool above effectively:
Select Town Hall: Choose your current Town Hall level. This sets the baseline "floor" weight for your village.
Input Heavy Defenses: Enter the levels for your Eagle Artillery, Scattershots/Monolith, and the combined levels of your Infernos and X-Bows. These are the primary drivers when you calculate war weight.
Enter Hero Levels: Sum up the levels of all your heroes (King + Queen + Warden + Champion) and enter the total.
Analyze Results: The tool will display your Estimated Total War Weight. Compare this against the "Maxed TH Peer" in the table to see where you stand.
Key Factors That Affect Calculate War Weight Results
When you calculate war weight, several distinct factors influence the final number. Understanding these can help in long-term account planning.
Splash Damage Defenses: Defenses like the Eagle Artillery, Scattershots, and Inferno Towers (Multi) carry significantly more weight than point defenses like Cannons or Archer Towers because they affect multiple units at once.
Town Hall Weapon: Starting at TH12, the Giga Tesla/Inferno is a defense itself. Upgrading the TH weapon level directly increases weight.
Hero Levels: High-level heroes add weight, but generally, the offensive value they provide outweighs the defensive penalty. It is rarely advised to stop upgrading heroes to save weight.
Wall Levels: While individually light, 300+ walls upgraded to max level add a noticeable amount of "passive" weight that can tip the scales in strict matchmaking.
Offensive Weight: Though not visible on the war map, your troop levels, spell levels, and army camp capacity contribute to an "offensive weight" that also impacts matchmaking, preventing pure defensive engineering.
Placement vs. Level: Placing a new defense (placing the level 1 Inferno) adds a huge initial chunk of weight (the "unlock penalty"). Upgrading it subsequently adds less weight incrementally.
Frequently Asked Questions (FAQ)
Does removing decorations lower my war weight?
No. Decorations, obstacles, and trees do not affect how you calculate war weight. They are purely cosmetic.
Why does my war weight change without upgrades?
Supercell occasionally adjusts the weights of specific buildings in maintenance updates. A defense that was considered "heavy" last month might be reduced to balance the meta.
Is it better to upgrade walls or defenses first for war weight?
Generally, walls. Walls add weight, but significantly less per gold spent compared to heavy defenses like X-Bows. This keeps your weight lower while dumping resources.
How do I check my exact war weight in-game?
On Battle Day, execute a "scout" on your own base using a friendly challenge or ask a clanmate to view your base in war. Count the Gold in one storage and multiply by the number of storages (plus the TH). This total gold available is your raw defensive weight.
What is "roster engineering"?
This involves managing the mix of TH levels in a war roster (e.g., putting in low TH weights at the bottom) to manipulate the average clan weight.
Does the builder base affect war weight?
No. Progress in the Builder Base / Night Village has zero impact on the Home Village Clan War matchmaking or weight.
Can I lower my war weight?
You cannot lower it directly without selling buildings (which is no longer possible). The only way to "lower" your relative weight is to upgrade your Town Hall and Offense without touching your defenses.
What is the weight of a Spell Tower?
Spell Towers (TH15+) are considered heavy defenses, similar to Scattershots. You should calculate war weight carefully before dropping both immediately upon reaching TH15.
