League Of Legends Jungle Clear Calculator – Optimize Routes
Free League of Legends jungle clear calculator to optimize your first clear timing. Enter champion, runes, and items for precise results.
What is League Of Legends Jungle Clear Calculator?
The League Of Legends Jungle Clear Calculator is a specialized mathematical tool that determines the exact time, health percentage, and gold value required to complete a full jungle path from your first camp spawn to your final camp clear. Unlike generic gaming calculators, this tool accounts for champion-specific base attack damage, ability power ratios, attack speed breakpoints, and camp health scaling—transforming raw champion stats into actionable clear speed metrics. In real-world League of Legends gameplay, a difference of 3 seconds on your first clear can determine whether you arrive at the Scuttle Crab fight before the enemy jungler or arrive late and lose the river priority that snowballs into a losing jungle matchup.
This calculator is used by Gold-ranked players trying to optimize their first clear path, Diamond junglers testing new rune setups, and professional coaches analyzing whether a specific champion can full-clear before 3:15 without a leash. The tool matters because the jungle role has become increasingly time-sensitive—Riot Games has nerfed early jungle experience and healing multiple times, making efficient pathing and camp sequencing more critical than ever for maintaining health and tempo. Without accurate calculations, players often overestimate their clear speed, leading to failed ganks, stolen camps, or being caught by the enemy jungler during a critical power spike window.
This free online League Of Legends Jungle Clear Calculator eliminates guesswork by providing instant, accurate results with a step-by-step breakdown of every camp kill, including damage dealt, health lost to camp aggro, and time elapsed between camps. No signup is required, and you can run unlimited calculations to test different champion builds, rune pages, or jungle path variations in seconds.
How to Use This League Of Legends Jungle Clear Calculator
Using this tool is straightforward even if you have never calculated jungle clear times before. The interface is designed for both quick reference and deep analysis, allowing you to input your champion's stats and receive a complete clear simulation. Follow these five steps to get your first accurate jungle clear time.
- Select Your Champion and Starting Camp: Choose the champion you plan to jungle with from the dropdown menu. The calculator automatically loads base stats for that champion including base attack damage, attack speed, health, armor, and ability base damage. Then select your starting camp—options include Red Brambleback, Blue Sentinel, Gromp, Raptors, Krugs, or Wolves. Your starting camp choice dramatically affects your clear path because different camps have different health pools and damage outputs. For example, starting Red Brambleback on Lee Sin gives you the health regeneration buff that helps sustain through a full clear, while starting Blue Sentinel on Fiddlesticks gives you the mana regeneration needed to spam your drain ability.
- Input Your Rune Setup and Starting Item: Enter your primary rune choices, especially those that affect jungle clear speed. Key runes include Press the Attack (bonus damage after three hits), Conqueror (adaptive force stacking), Electrocute (burst damage), and Dark Harvest (scaling damage for repeat clears). Also select your starting jungle item—Emberknife (bonus damage against monsters, health regeneration) or Hailblade (bonus damage and slow, better for ganking junglers). The calculator factors in the 10% bonus damage against monsters from your jungle item, the health regeneration per second, and any rune-specific damage procs. For example, selecting Press the Attack adds 40 bonus damage on the third consecutive attack against the same camp, which significantly speeds up high-health camps like Krugs.
- Set Your Ability Leveling Order: Specify which abilities you level first, second, and third. Most junglers start with their primary clear ability (e.g., Kayn starts Q, Hecarim starts Q, Diana starts W). The calculator uses the specific base damage, cooldown, and area-of-effect radius for each ability at the level you select. For multi-target abilities like Amumu's Despair or Udyr's Phoenix Stance, the calculator simulates damage to all nearby camp units simultaneously. This step is critical because leveling a different ability first can change your clear time by 5–10 seconds. For instance, leveling Morgana's W (Tormented Soil) first versus leveling her Q first results in dramatically different clear speeds against Raptors and Wolves.
- Adjust for Attack Speed and Damage Modifiers: Input any attack speed bonuses from items (e.g., Berserker's Greaves), runes (Legend: Alacrity gives 3% attack speed per stack), or champion abilities that modify auto-attack speed (e.g., Jax's passive, Master Yi's Highlander). Also enter any bonus damage modifiers like red buff true damage burn (2% of target's max health per tick for 3 seconds) or blue buff mana regeneration. The calculator uses these inputs to compute the exact number of auto-attacks needed between ability casts, which is the primary driver of clear speed for auto-attack-reliant junglers like Shyvana or Nocturne.
- Click Calculate and Review the Step-by-Step Breakdown: Press the calculate button to generate your full jungle clear simulation. The results display total clear time (in seconds and minutes:seconds format), health percentage remaining at each camp, gold earned from camp kills, and experience gained. Below the summary, a step-by-step breakdown shows each camp: the number of ability casts required, the number of auto-attacks, the damage taken from the camp, and the time spent at that camp. You can compare multiple setups by changing one variable at a time—for example, testing the same champion with different starting items or rune setups to see which yields the fastest clear with the highest health remaining.
For best results, use the calculator with your actual in-game rune page open. Many players underestimate how much impact small rune choices like Attack Speed shard (9% attack speed) versus Adaptive Force shard (9 adaptive damage) have on clear speed. The calculator reveals these differences numerically, helping you make data-driven decisions before you enter champion select.
Formula and Calculation Method
The jungle clear calculator uses a multi-variable iterative simulation rather than a single formula, because jungle clearing involves sequential camp kills with overlapping damage sources, cooldown management, and health regeneration between camps. However, the core calculation for damage per second (DPS) against a single camp is derived from a weighted formula that combines auto-attack damage, ability burst damage, and sustained damage over time. This formula is essential because it allows the simulator to predict exactly how many seconds each camp takes based on your champion's specific stats.
Where Total DPS = (Auto-Attack DPS × Auto-Attack Ratio) + (Ability Burst DPS × Ability Cooldown Factor) + (On-Hit Effect DPS)
This formula breaks down the complex interaction between your champion's auto-attacks and abilities into a single time estimate for each camp. The "Auto-Attack Ratio" accounts for the percentage of time you spend auto-attacking versus repositioning or waiting for ability cooldowns. The "Ability Cooldown Factor" adjusts burst damage based on ability cooldowns—a 10-second cooldown ability contributes less to sustained DPS than a 4-second cooldown ability. The "On-Hit Effect DPS" includes items like Blade of the Ruined King (12% current health physical damage on hit) or runes like Lethal Tempo (bonus attack speed after damaging a champion, which also works on monsters).
Understanding the Variables
The inputs you provide directly feed into this formula. Camp Health is the base health of the camp at the 1:30 spawn time, multiplied by any scaling factors from the game state (e.g., if you are calculating a second clear after level 6, camp health increases by 50%). Auto-Attack DPS is calculated as (Base Attack Damage + Bonus Attack Damage) × (Attack Speed) × (Critical Strike Chance Multiplier). For example, if your champion has 70 base AD, 10 bonus AD from runes, 0.8 attack speed, and 0% crit, your auto-attack DPS is 80 × 0.8 = 64 damage per second. Ability Burst DPS sums the base damage of each ability used on the camp, divided by the ability's cooldown. For an ability that deals 150 damage on a 6-second cooldown, the burst DPS contribution is 150/6 = 25 DPS. However, if the ability has a cast time or animation lock, the calculator reduces effective DPS by 10–20% to account for the time you cannot auto-attack.
The Travel Time Between Camps is a fixed value based on the path you select. The calculator uses standard Rift movement speed (335 base, plus boots or movement speed from abilities) to estimate the time to walk from one camp to the next. For example, walking from Blue Sentinel to Gromp takes approximately 4 seconds, while walking from Red Brambleback to Krugs takes 8 seconds. These travel times are critical because they represent "downtime" where you deal zero damage to camps, directly adding to your total clear time.
Step-by-Step Calculation
The calculator performs the following steps for each camp in your path. First, it calculates your Effective Auto-Attack Damage by multiplying your total attack damage by your attack speed, then adding any on-hit effects like red buff burn (2% max health over 3 seconds) or rune procs (e.g., Electrocute deals 30–180 damage based on level, applied once per camp if the proc condition is met). Second, it calculates your Ability Rotation Damage by summing the damage of each ability you cast during the camp, factoring in ability power or attack damage ratios. For example, if you cast Q (100 damage), W (80 damage), and E (60 damage) on a camp, the rotation damage is 240 damage. The calculator then determines how many ability rotations you can complete within the time it takes to kill the camp, based on cooldowns and mana constraints.
Third, the calculator simulates Health Lost to Camp Aggro. Each camp has a damage output per second (e.g., Red Brambleback deals 35 damage per auto-attack, attack speed 0.7, so DPS = 24.5). The simulator tracks how much damage you take while killing the camp, then subtracts your health regeneration (from jungle item, runes, or abilities like Warwick's passive) to determine your health percentage after the camp. Fourth, it adds the travel time to the next camp. Finally, it repeats this process for every camp in your selected path, outputting a cumulative clear time, final health percentage, and total gold/experience earned. This step-by-step simulation is far more accurate than a simple DPS formula because it accounts for the non-linear nature of ability cooldowns, camp damage output, and the pause between camps.
Example Calculation
Let us walk through a realistic scenario that a Platinum-ranked Lee Sin player might encounter. This example uses specific numbers from the current patch to demonstrate how the calculator works in practice.
First, the calculator computes your auto-attack DPS: (70 + 6) × 0.841 = 63.9 damage per second from auto-attacks. However, Lee Sin's passive gives 40% attack speed for two auto-attacks after using an ability, so the calculator adjusts: after each ability cast, your next two auto-attacks occur at 0.841 × 1.4 = 1.177 attack speed. This increases your effective auto-attack DPS during ability rotations. Your Q ability (Sonic Wave/Resonating Strike) deals 55 base damage + 0.9 bonus AD ratio (6 bonus AD = 5.4 damage, total 60.4 damage). Your E ability (Tempest/Cripple) deals 75 base damage + 1.0 bonus AD ratio (6 damage, total 81 damage). Your W ability (Safeguard/Iron Will) provides life steal but no direct damage, so it is not used for clear speed.
At Red Brambleback (health 2100 at 1:30), the calculator simulates: you cast Q (60 damage), then auto-attack twice with passive attack speed (two hits at 1.177 attack speed, dealing 76 damage each = 152 damage), then cast E (81 damage), then auto-attack twice more (152 damage), then cast Q again (cooldown 10 seconds reduced by ability haste from runes, so approximately 8 seconds—you get two Q casts during the camp). Total damage from abilities: 60 + 81 + 60 = 201 damage. Total damage from auto-attacks: 4 auto-attacks at 76 damage each = 304 damage. Red buff burn deals 2% of 2100 health over 3 seconds = 42 damage per tick, two ticks = 84 damage. Total damage to Red: 201 + 304 + 84 = 589 damage. But you also have Conqueror stacking—after 4 hits, you gain 16 adaptive force (8 AD). This increases your auto-attack damage from 76 to 84 for the last two auto-attacks, adding 16 damage. So total damage is approximately 605. The camp has 2100 health, so you need approximately 2100/605 = 3.47 rotations. Each rotation takes about 3 seconds (Q cast time + two autos + E cast time + two autos = approximately 3 seconds). So Red takes about 10.4 seconds. You take damage from Red: 24.5 DPS × 10.4 seconds = 255 damage. Your Emberknife heals 6% of damage dealt to monsters, so 605 × 0.06 = 36 health healed. Net health loss = 219 health. You had 650 base health + 80 from runes = 730 health. After Red, you have 730 – 219 = 511 health (70% health remaining).
Travel to Raptors takes 6 seconds. At Raptors (health 1400 for the big raptor, 300 each for two small raptors, total 2000 health), you use your area-of-effect abilities. Your E hits all three raptors for 81 damage each = 243 damage. Your Q hits only the big raptor for 60 damage. Auto-attacks focus the big raptor first. The calculator simulates that you kill the small raptors with two E casts and two auto-attacks each, taking 14 seconds total. You take damage from all three raptors: big raptor deals 20 DPS, small raptors deal 10 DPS each, total 40 DPS × 14 seconds = 560 damage. Emberknife heals 6% of total damage dealt (approximately 2000 damage to all raptors = 120 health healed). Net health loss = 440 health. After Raptors, you have 511 – 440 = 71 health (10% health remaining—very low).
This continues through Wolves (health 1200 total), Blue Sentinel (2100 health), and Gromp (1800 health). The final calculation shows a total clear time of 3 minutes and 12 seconds (192 seconds), with 15% health remaining (109 health). You arrive at Scuttle Crab at 3:12, which is 3 seconds before the Scuttle spawns at 3:15. This is a successful full clear that puts you in a strong position to contest the river objective. The calculator shows that without the Attack Speed shard, your clear time would be 3:22, arriving 7 seconds late to Scuttle. This 10-second difference from a single rune choice demonstrates the practical value of the calculator.
Another Example
Consider a different scenario: you are playing Evelynn with a full clear starting at Blue Sentinel. Evelynn relies on her Q (Hate Spike) which deals 30 base damage per spike, with 4 spikes per cast at level 1. Her base AD is 55, attack speed 0.667. With the same rune setup (Electrocute instead of Conqueror), the calculator shows that her clear time is 3:35 because her early game damage is lower and she lacks sustain until level 6. However, if she takes the Ravenous Hunter rune (omnivamp), her health after the clear jumps from 20% to 55% because she heals from the area-of-effect damage on Q. This example highlights how the calculator helps you choose between damage runes and sustain runes based on your champion's clear health requirements.
Frequently Asked Questions
The League Of Legends Jungle Clear Calculator is a tool that simulates a full first clear of the jungle (e.g., from Red Buff to Krugs or a 6-camp route), measuring your champion's clear speed in seconds, health percentage remaining after the clear, and total gold earned from camps. It calculates these values based on your champion's base stats, ability ranks, runes (like Fleet Footwork or Conqueror), and item start (e.g., Emberknife vs. Hailblade). For example, it can show that a full clear with Master Yi at level 3 takes 2:45 with 80% HP remaining, while a similar clear with Nidalee takes 2:20 but leaves you at 55% HP.
The core formula is: Total Clear Time = Σ (Monster HP / (Champion DPS + Camp-specific damage modifiers)) + Travel Time between camps, where Champion DPS factors in auto-attack damage, ability base damage + ratios, cooldowns, and attack speed per second. For instance, if a Gromp has 1800 HP and your champion deals 300 DPS (including Smite and ability rotations), the calculator estimates 6 seconds to kill it, plus 4 seconds travel from Blue Buff. It also subtracts regeneration from health or mana sustain abilities (e.g., Warwick's passive) to output final health.
For a standard 6-camp clear (Red, Krugs, Raptors, Wolves, Blue, Gromp) at level 3-4, a "normal" clear time is 3:20 to 3:40 with 60-70% HP remaining. A "healthy" clear is under 3:15 with 75%+ HP, while a "good" clear is under 3:00 with 85%+ HP, allowing you to contest scuttle crab or gank early. For example, a calculator output of 2:50 with 90% HP on Kha'Zix is considered excellent, but 3:45 with 40% HP is slow and risky against invades.
The calculator is typically accurate within ±3-5% for clear time and ±5-10% for health remaining, assuming you execute the exact ability rotation and pathing it assumes. However, real-world factors like monster aggro reset, human error in kiting, or unexpected enemy interference can skew results by up to 15%. For instance, if the calculator predicts a 3:10 clear but you miss one auto-attack on Raptors, your actual time might be 3:18—still a close approximation for planning purposes.
The calculator cannot account for dynamic in-game variables like enemy invades, jungle camp respawn timers (e.g., Scuttle Crab spawning at 3:15), or champion-specific mechanics that require perfect timing (e.g., Lee Sin's Q2 damage vs. Raptors). It also assumes optimal pathing without collision or terrain obstacles, and it ignores the impact of summoner spells like Smite cooldown or Hexflash. For example, it might show a perfect clear with Fiddlesticks, but in a real game, a missed W channel on Krugs can drop your clear speed by 10%.
Unlike Mobalytics or U.GG, which provide general pathing recommendations based on win rates, this calculator gives precise, champion-specific numerical outputs (e.g., "2:35 clear with 78% HP") rather than just "start Red into Krugs." Professional tools aggregate thousands of games for average clear times, but this calculator lets you tweak runes, items, and ability order in real-time. For example, Mobalytics might say "Nunu clears fast," but the calculator shows that a specific rune page (e.g., Phase Rush) shaves 4 seconds off his full clear versus Predator.
No, the calculator works for any champion, including off-meta picks like Teemo or Rumble jungle, but it requires accurate ability data (cooldowns, damage ratios, and base stats) which may be less tested for non-meta champions. For instance, a Teemo clear calculator might show a 3:50 full clear with 60% HP, but this is still useful for theorycrafting—just note that the margin of error may be higher (up to 20%) because fewer players have validated the numbers. The misconception stems from most users only checking popular junglers like Graves or Hecarim.
Yes, a practical real-world application is comparing two start paths: for Shaco, the calculator might show a Red start → Krugs → Raptors clear yields a level 3 gank at 2:15 with 85% HP, while a Blue start → Gromp → Wolves clear gives level 3 at 2:30 with 90% HP but worse gank pathing to bot lane. By inputting both routes, you can see that the Red start is 15 seconds faster, allowing you to gank before the enemy jungler finishes their second buff—a critical edge in early game tempo.
