Dota 2 Calculator: The Attack Speed Calculator Tool for Dota 2

The Attack Speed Calculator Tool

The Attack Speed Calculator Tool turns attack speed into something you can feel: attacks per second, time per attack and right-click DPS for any hero at any level. Add items and watch the hit metronome speed up. Axe tried to count his punches per second. Axe punched the calculator. This one survived.

1. Pick a hero and a level. Base attack speed, agility and BAT come from the game data. Or switch to Custom and type your own BAT and attack speed.
2. Click items (up to six) and add bonus attack speed or agility from talents and spells.
3. Read the result: attacks per second, time per attack, total attack speed against the 700 cap and DPS. The metronome shows every hit with and without items.

Axe explains

Attack speed in 10 seconds

1. 700max attack speed, the cap.
2. 20min attack speed (shifted by base).
3. 1.7BAT of 92 of 127 heroes.
4. 1attack speed per point of agility.

More attack speed = more punches. Axe likes more punches.

Dota 2 attack speed formula

Attack speed and base attack time (BAT) together decide how often a hero attacks:

Example: Axe at level 1 has 100 base attack speed and 18 agility, so 118 attack speed. With a 1.7 BAT that is 118 ÷ 170 = 0.69 attacks per second, or one attack every 1.44 seconds.

• Base attack speed is 100 for 90 of 127 heroes. The others are listed below.
• Agility adds 1 attack speed per point, so agility items count too.
• Bonus attack speed comes from items, talents and spells and is simply added.
• Percentage bonuses multiply the total. Butterfly gives +20%, so 200 attack speed becomes 240.

Attack speed cap: 700 max, 20 min

Attack speed is limited to 700. Everything above it is wasted, and the tool shows how much. The minimum is 20, but it moves with the hero's base attack speed: Tiny (85 base) can drop to 5, Broodmother (125 base) never goes below 45. Only a few spells, like Marci's Unleash and Troll Warlord's Battle Trance, can go past 700.

Attacks per second at each attack speed. The last row is the cap.

Base attack speed of every Dota 2 hero

90 heroes start with 100 attack speed. The rest start higher or lower, and that shifts their whole attack speed range. Broodmother has the highest base (125), Tiny the lowest (85).

Every other hero: 100. Source: Liquipedia's base attack speed table, checked against all 127 heroes.

BAT and attack speed: why a low BAT is so strong

BAT divides everything. The same 300 attack speed gives 2.14 attacks per second with a 1.4 BAT, 1.76 with 1.7 and 1.50 with 2.0. That is why heroes with a low BAT get so much out of every attack speed item. 92 of 127 heroes have 1.7. See every hero's BAT in the Hero Stats Ranker Tool.

Attack speed vs damage: what gives more DPS?

Right-click DPS is damage per hit × attacks per second. Both multiply each other, so the one you have less of is usually the better buy. A simple rule: 1 attack speed is worth (your damage ÷ your attack speed) damage.

Example: Juggernaut at level 15 has about 94 damage and 181 attack speed. One point of attack speed is worth 0.52 damage for him, so +60 attack speed from a Hyperstone gives as much DPS as about +31 damage.

• High damage, low attack speed: attack speed gives more DPS.
• High attack speed, low damage: damage gives more DPS.
• Near the 700 cap: more attack speed does nothing, buy damage.

Attack speed also makes every on-hit effect trigger more often: lifesteal, bash chances, Maelstrom procs. Axe has one on-hit effect: the hit. Axe is happy.
