How Combat Calculus works
Roll your attack twenty thousand times before you pick up a die.
What you pick
Combat Calculus is a Warhammer 40k expected damage calculator for one unit attacking another. Pick both from any faction's 11th edition catalogue and set the defender's unit size. Choose Ranged or Melee, then tick the attacker's weapons. For a squad, enter how many of each model it fields. The pickers skip Legends units.
What you get
You get average damage, average models killed, wipe chance and zero-kill chance, plus a chart of the damage distribution. A breakdown follows each weapon from attacks to hits, wounds, unsaved wounds and damage. It marks where an invulnerable save, Feel No Pain or an Anti ability applied.
How the dice roll
Each simulation resolves the attack 20,000 times, rolling D6 attacks and D3 damage fresh each time. It takes Torrent, Sustained Hits and Anti from each weapon's profile, plus unconditional Lethal Hits and Devastating Wounds. Kills count model by model, with excess damage lost. Feel No Pain applies only when the defender's own datasheet has it.
§ Questions
- Is there a 40k damage calculator for 11th edition?
- Yes. Combat Calculus is built for 11th edition: cover worsens a ranged attack's Ballistic Skill by 1 instead of improving the save, so cover and -1 to hit make -2.
- How does this mathhammer calculator work out expected damage?
- By simulation. Combat Calculus resolves the attack 20,000 times with fresh rolls and averages the results, so figures can shift a little between runs.
- Can I add Stratagems, auras and modifiers like +1 to hit?
- Yes, as toggles for their effects: hit and wound modifiers, re-rolls, Strength, AP, Damage, cover, critical hits and Fire Overwatch. Toggles matching either unit's ability text start switched on. You set army rules, detachment rules and Stratagems yourself.
- Does the calculator handle Rapid Fire, Melta and Heavy weapons?
- Yes. The baseline assumes a target beyond half range and an attacker that moved over 3 inches. Extra rows show within half range, moved 3 inches or less, or both, when that changes average damage.
- Can I compare two whole army lists at once?
- No. Combat Calculus pits one unit against another, one way. Kill Grid builds the unit-against-unit matrix from two pasted lists, both ways.
