Age of Sigmar Damage Calculator

Estimate expected damage, unsaved wounds, and models slain from one attack sequence.

Attacking Models

Attacks per Model

To Hit (2-6)

Hit Modifier (e.g. +1, -1)

To Wound (2-6)

Wound Modifier (e.g. +1, -1)

Rend (use 0, -1, -2...)

Damage per Unsaved Wound

Enemy Save (2-7, use 7 for none)

Save Modifier (cover / commands)

Ward (2-7, use 7 for none)

Target Wounds per Model

Attacker Points (optional)

Tip: This tool gives average outcomes ("mathhammer"). Real dice can spike high or low.

How this Age of Sigmar calculator helps

This calculator is a quick AoS expected damage tool for planning attacks before a game or while building lists. Instead of guessing whether a unit can remove a screen or threaten a hero, you can estimate the average result from your attack profile in seconds.

Compute expected hits, wounds, unsaved wounds, and final damage
Account for hit/wound modifiers, rend, armor saves, and wards
Estimate how many models you remove based on wounds per model
Check points efficiency with a simple damage-per-100-points output

What each input means

Attacking profile

Attacking Models multiplied by Attacks per Model gives total attacks. Then set your To Hit, To Wound, Rend, and Damage.

Defensive profile

Set the defender's Save and Ward. Use 7 if there is no save roll of that type (for example no ward).

Modifiers

Use positive values to improve rolls and negative values to worsen them. Rend should be entered as 0, -1, -2, and so on.

The math behind the result

The calculator uses standard probability for d6 roll checks:

Chance to pass a roll is based on the required value after modifiers
Expected Hits = Total Attacks × Hit Chance
Expected Wounds = Expected Hits × Wound Chance
Expected Unsaved = Expected Wounds × (1 - Save Chance)
Expected Damage = Expected Unsaved × Damage × (1 - Ward Chance)

That makes it useful for fast mathhammer decisions: commit now, hold back, or charge a different target.

Practical use cases in real games

1) Deciding where to send your hammer

Check expected damage into two different targets. If one target has strong armor but no ward, and another has weak armor but a 5+ ward, this calculator will quickly reveal which one is more efficient to attack first.

2) Planning command point usage

Try one run with +1 to hit, then another with +1 save on the defender. The difference in expected damage helps you decide whether the command point is worth spending in that combat phase.

3) Testing list changes

Compare units by points efficiency. If Unit A deals 4.5 expected damage per 100 points while Unit B deals 3.2, you can see which profile gives you better output in your local meta.

Example scenario

Imagine 10 models, 2 attacks each, hitting and wounding on 3+, rend -1, damage 1. Target has a 4+ save and no ward.

Total attacks: 20
Expected hits: 13.33
Expected wounds: 8.89
After 5+ save from rend: 5.93 unsaved
Final expected damage: about 5.93

That is enough to heavily damage an elite unit or remove multiple 2-wound infantry models.

Important limitations

This is intentionally a clean baseline calculator. It does not automatically include special rules like exploding hits, mortal wounds on 6s, strike-first effects, recursion, or conditional buffs. For best accuracy, convert those effects into adjusted attack counts or run separate calculations.

It shows averages, not full probability distributions
It assumes one attack profile at a time
It does not model pile-in geometry or model positioning

Final tip

Use expected value as a decision aid, not a guarantee. In Age of Sigmar, smart positioning and objective play still beat pure damage racing. But with this calculator, your choices become faster, cleaner, and more informed.
