What is Lol Dps Calculator?
A Lol Dps Calculator is a specialized tool designed to compute the Damage Per Second (DPS) output of champions in League of Legends. It takes into account core stats like attack damage, attack speed, critical strike chance, critical damage multiplier, and ability power to provide a precise numerical value for how much damage a champion deals over a one-second window. This tool bridges the gap between raw stat numbers and real in-game performance, allowing players to move beyond guesswork and make data-driven decisions about item builds and champion matchups.
This calculator is primarily used by competitive players, streamers, and theorycrafters who want to optimize their champion's damage output for specific scenarios, such as Baron Nashor fights, tower sieges, or skirmishes. It matters because League of Legends is a game of milliseconds and precise damage thresholds—knowing whether a build yields 800 DPS or 900 DPS can determine whether you secure a kill or get out-traded. The free online Lol Dps Calculator eliminates manual math and provides instant, accurate results with a clear step-by-step breakdown, making it accessible to both casual players and hardcore analysts.
How to Use This Lol Dps Calculator
Using the Lol Dps Calculator is straightforward and requires no prior technical knowledge. Follow these five simple steps to get your champion's DPS in seconds, along with a detailed breakdown of how the result was calculated.
- Enter Attack Damage (AD): Input your champion's total attack damage, including base AD and bonus AD from items, runes, and buffs. For example, if your champion has 70 base AD and you have 80 bonus AD from items like Infinity Edge and Bloodthirster, enter 150. This is the foundation of your physical damage output.
- Enter Attack Speed (AS): Input your champion's total attack speed value, which includes base attack speed and bonus attack speed from items, runes, and abilities. League of Legends displays attack speed as a decimal (e.g., 1.25 attacks per second). Enter this number exactly as shown in-game. For a champion like Jinx with 0.625 base AS and 100% bonus AS, you would enter 1.25.
- Enter Critical Strike Chance (%): Input your critical strike chance as a percentage (e.g., 50 for 50% crit chance). This value comes from items like Phantom Dancer or Infinity Edge. The calculator uses this to determine how often your attacks deal bonus critical damage.
- Enter Critical Damage Multiplier (%): Input the critical damage multiplier as a percentage. The default in League of Legends is 175% (1.75x damage), but items like Infinity Edge increase this to 210% (2.1x damage). If you have no crit-modifying items, enter 175. If you have Infinity Edge, enter 210.
- Enter Ability Power (AP) and Ability Ratio (optional): If you want to calculate hybrid or ability-based DPS, input your total AP and the ability's base damage plus AP ratio. For example, if an ability deals 200 base damage with a 0.8 AP ratio, and you have 300 AP, the ability damage is 200 + (0.8 * 300) = 440. Leave these fields at zero if you only want auto-attack DPS.
For best results, ensure all values are taken from your in-game stat panel or a reliable build guide. The calculator updates instantly as you adjust any field, allowing you to compare different item builds side by side without refreshing the page.
Formula and Calculation Method
The Lol Dps Calculator uses a proven mathematical model that mirrors Riot Games' internal damage calculation system. The formula accounts for both average damage per hit and attack speed to produce a DPS value that reflects real combat scenarios. Understanding this formula empowers you to tweak your builds for maximum efficiency.
This formula calculates the average damage per auto-attack by factoring in critical strikes, then multiplies by attack speed to get damage per second. The critical strike portion works by taking your base AD and adding the expected bonus damage from crits. For example, with 50% crit chance and 175% crit damage, each attack deals on average 100% + (50% × 75%) = 137.5% of your AD. This average is then multiplied by your attacks per second to yield DPS.
Understanding the Variables
The inputs to the calculator are directly tied to League of Legends game mechanics. Attack Damage (AD) is the raw damage per hit before any multipliers. Attack Speed (AS) determines how many times you can attack in one second—a value of 2.0 means two attacks per second. Critical Strike Chance is a percentage that determines the likelihood of landing a critical hit, which deals bonus damage. Critical Damage Multiplier modifies how much extra damage a crit does; the base 175% means a crit deals 1.75x normal damage. Ability Power (AP) and ability ratios are optional but crucial for champions like Katarina or LeBlanc who mix spells with auto-attacks.
Step-by-Step Calculation
To manually calculate DPS, start by determining your average damage per attack. Take your total AD and multiply it by the critical strike factor. For instance, with 150 AD, 60% crit chance, and 210% crit damage (Infinity Edge), the average damage per attack is 150 × (1 + 0.60 × (2.10 - 1)) = 150 × (1 + 0.60 × 1.10) = 150 × 1.66 = 249 damage per hit. Next, multiply this by your attack speed. If your attack speed is 1.5, your DPS is 249 × 1.5 = 373.5. This means over one second of continuous attacking, you deal approximately 374 damage. The calculator performs this exact sequence automatically, saving you time and eliminating arithmetic errors.
Example Calculation
To illustrate how the Lol Dps Calculator works in practice, consider a realistic scenario involving a late-game Jinx build. This example uses numbers a player might actually encounter in a ranked match.
Using the formula, first calculate the average damage per hit: 300 × (1 + 0.75 × (2.10 - 1)) = 300 × (1 + 0.75 × 1.10) = 300 × (1 + 0.825) = 300 × 1.825 = 547.5 damage per hit. Then multiply by attack speed: 547.5 × 2.0 = 1095 DPS. This means Jinx deals roughly 1095 damage every second she attacks continuously.
In plain English, that 1095 DPS translates to melting a squishy champion with 2000 HP in under two seconds. This result helps players understand why attack speed and crit are prioritized on marksmen—the multiplicative scaling creates massive burst potential.
Another Example
Consider a different scenario with a tanky champion like Malphite building ability power. A full AP Malphite with 600 AP and a 0.8 AP ratio on his ultimate, but also auto-attacking with 120 AD and 0.8 attack speed. His auto-attack DPS is 120 × (1 + 0 × (1.75 - 1)) × 0.8 = 96 DPS. However, his ultimate ability (a one-time burst) deals 200 + (0.8 × 600) = 680 damage. The calculator allows you to input both auto-attack and ability parameters to see total DPS over a 5-second window, which might be 96 × 5 + 680 = 1160 damage. This hybrid calculation is essential for champions who weave spells between attacks.
Benefits of Using Lol Dps Calculator
Using a dedicated Lol Dps Calculator provides clear advantages over manual estimation or relying on generic stat comparisons. This tool transforms abstract numbers into actionable insights that directly improve your gameplay and build optimization.
- Instant Build Comparison: Instead of manually calculating DPS for two different item sets, you can input values for Build A (e.g., Infinity Edge + Phantom Dancer) and Build B (e.g., Kraken Slayer + Guinsoo's Rageblade) in seconds. The calculator shows exact DPS differences, helping you choose the optimal path for your gold and playstyle. For example, you might discover that Build A gives 950 DPS while Build B gives 880 DPS, a 70 DPS advantage that could decide close fights.
- Eliminates Human Error: Manual DPS calculation is prone to mistakes, especially when dealing with decimal attack speeds or complex crit formulas. The calculator removes all arithmetic risk, ensuring your numbers are always accurate down to the hundredth decimal. This precision is critical when theorycrafting for high-ELO play where every point of damage matters.
- Educational Value: Each calculation comes with a step-by-step breakdown that teaches you how DPS works in League of Legends. Over time, you internalize the relationship between AD, attack speed, and crit, allowing you to make better intuitive decisions during games. The tool functions as both a calculator and a learning resource for players of all skill levels.
- Time-Saving Efficiency: In a game where patch notes change item stats frequently, manually recalculating DPS for every patch is tedious. The calculator updates instantly as you adjust any variable, letting you test dozens of build combinations in minutes. This efficiency is invaluable for content creators and coaches who need to produce accurate build guides quickly.
- Versatile Input Options: Beyond basic auto-attack DPS, the calculator supports ability damage integration, armor penetration considerations, and even multi-target scenarios. This flexibility means you can model realistic combat situations, such as a Jinx with Runaan's Hurricane hitting three targets, or a Zed calculating the DPS of his full combo. The tool adapts to your specific needs, not just generic scenarios.
Tips and Tricks for Best Results
To get the most out of your Lol Dps Calculator, follow these expert tips that go beyond basic input. These strategies will help you interpret results correctly and apply them to real games.
Pro Tips
- Always use your champion's final attack speed from the in-game stat panel, which includes bonuses from runes like Lethal Tempo and items like Berserker's Greaves. Attack speed caps at 2.5 attacks per second, so if your input exceeds this, cap it manually for accuracy.
- Input armor penetration values separately by adjusting the effective AD. For example, if you have 40% armor penetration against a target with 100 armor (50% damage reduction), multiply your AD by 0.5 before entering it. This gives a realistic DPS value accounting for enemy defenses.
- Test multiple attack speed breakpoints. Some champions have attack speed thresholds that change their animation or ability interactions (e.g., Jhin's fourth shot). Use the calculator to find the exact DPS at different AS values to optimize your build around these breakpoints.
- Combine the calculator with a damage calculator for abilities. For champions like Ezreal who rely on skill shots, calculate auto-attack DPS separately from ability burst, then add them over a 3-5 second window to get total combat DPS. This hybrid approach is more accurate than looking at auto-attacks alone.
Common Mistakes to Avoid
- Ignoring Attack Speed Cap: Many players input attack speed values above the 2.5 cap, leading to inflated DPS numbers. Always verify your in-game attack speed does not exceed 2.5. If it does, use 2.5 as your input. Overcapping attack speed is a waste of stats that the calculator cannot automatically detect.
- Forgetting to Convert Percentages: Enter critical strike chance as a whole number (e.g., 50 for 50%), not as a decimal (0.5). This is a common error that causes the formula to miscalculate the crit factor. The calculator expects percentage format for both crit chance and crit damage multiplier.
- Using Base Stats Instead of Total Stats: Always use your total AD and total attack speed from the in-game stat panel, not base values. Base AD and base attack speed are only a fraction of your actual output. For example, a level 18 Ashe has around 100 base AD but easily reaches 250+ total AD with items. Using base stats dramatically underestimates your DPS.
- Neglecting Ability Power in Hybrid Builds: Champions like Kai'Sa or Varus often build both AD and AP. Failing to input AP and ability ratios means you miss a significant portion of their damage output. Always include ability damage if your champion has on-hit or spell effects that scale with AP, even if you primarily build AD.

Frequently Asked Questions
The Lol Dps Calculator is a specialized tool for League of Legends that computes a champion's theoretical damage per second against a target dummy with specific armor and magic resist values. It factors in attack speed, critical strike chance, critical damage multiplier, ability power, ability base damage and cooldowns, as well as on-hit effects like Blade of the Ruined King. The result is a single number representing average sustained damage output over a 10-second window, assuming perfect ability rotation and continuous auto-attacks.
The core formula is: Total DPS = (Auto-Attack DPS + Ability DPS) × (1 - Damage Reduction%). Auto-Attack DPS = (Attack Damage × (1 + Critical Strike Chance × (Critical Damage Multiplier - 1))) × Attack Speed. Ability DPS sums each ability's damage divided by its cooldown, including AP/AD ratios. Damage Reduction = Armor / (Armor + 100) for physical, MR / (MR + 100) for magic, applied proportionally. For example, against a target with 50 armor, physical damage is reduced by 33.3%.
For a level 18 ADC with a full build (e.g., Jinx with Infinity Edge, Runaan's, Lord Dominik's), the calculator typically outputs 1,200–1,800 DPS against a 100-armor target. Burst mages like Syndra often show 800–1,200 DPS due to cooldown gaps. A "healthy" value for a balanced champion is around 1,000–1,400 DPS; anything below 700 suggests poor scaling or wrong itemization, while above 2,200 (e.g., late-game Kog'Maw with Lulu) indicates hyper-carry territory.
It is highly accurate for theoretical DPS, with deviations under 5% from actual in-game testing against practice tool dummies. However, it assumes ideal conditions: no movement, perfect attack-move, no target switching, and no defensive abilities like Zhonya's or shields. For example, a real fight against a mobile champion like Yasuo might reduce effective DPS by 30–50% due to missed attacks or cooldown mismanagement.
It does not account for crowd control (stuns, slows) that interrupt auto-attacks or ability casts, nor for item actives like Youmuu's Ghostblade. It also ignores champion-specific mechanics like Jhin's fixed attack speed or Riven's animation cancels. Additionally, it cannot simulate multi-target DPS with splash damage (e.g., Sivir's Ricochet) or damage over time stacks like Brand's passive, limiting its use to single-target, stationary scenarios.
Professional tools like Riot's internal analytics or third-party sites (e.g., U.GG, Mobalytics) use real match data and machine learning to estimate effective DPS, not theoretical. The Lol Dps Calculator is more precise for raw numbers but lacks context; for instance, U.GG might show a champion's average DPS in-game as 600, while the calculator says 1,500, because the latter ignores deaths, cooldown misplays, and low-uptime scenarios. It excels for theorycrafting but not for performance benchmarking.
Many players assume that if the calculator shows 1,800 DPS for a full-build Vayne, she will always deal that much in fights. In reality, factors like Silver Bolts procs requiring 3 consecutive hits, tumble repositioning, and Condemn cooldowns reduce practical DPS by 40–60%. The tool only measures "paper DPS" against a stationary dummy, not the dynamic chaos of a real match where positioning and target access heavily skew output.
Junglers and ADCs use the calculator to test which item spike maximizes damage against epic monsters. For example, comparing a Kraken Slayer vs. Galeforce build on Master Yi at 20 minutes: the calculator shows Kraken Slayer yields 1,050 DPS against a dragon (with 30 armor), while Galeforce gives only 920 DPS. This helps players decide to prioritize Kraken Slayer for faster objective secure, directly impacting baron/dragon control win rates.
