Skill Cooldown Calculator
Calculate effective skill cooldowns with CDR
About this calculator
The Skill Cooldown Calculator helps gamers determine the actual cooldown time of abilities after applying Cooldown Reduction (CDR) effects. This tool is essential for optimizing builds, planning ability rotations, and maximizing DPS in games like League of Legends, Dota 2, World of Warcraft, and other RPGs. By calculating effective cooldowns, players can make informed decisions about item builds, talent choices, and combat strategies to achieve optimal performance.
How to use
Enter your skill's base cooldown time in seconds, then input your total Cooldown Reduction percentage from items, talents, or buffs. The calculator will instantly display your effective cooldown time, showing how much faster you can use your abilities with CDR applied.
Frequently asked questions
How does CDR affect skill cooldowns?
CDR reduces the time between ability uses. For example, 25% CDR on a 10-second skill makes it 7.5 seconds.
Is there a maximum CDR limit in games?
Most games cap CDR between 40-45% to prevent abilities from becoming too spammable and maintain game balance.
Does CDR stack additively or multiplicatively?
In most games, CDR from different sources stacks additively up to the maximum cap, then additional CDR is ignored.
