League of Legends Healing Calculator

Calculate the total healing output of your abilities in League of Legends. Factor in AP scaling, Heal and Shield Power, Grievous Wounds reduction, and Spirit Visage bonuses.

Ability Power Scaling

Interpreting Your Result

A single-target heal of 400+ is considered "High Sustain," while group heals (like Sona or Taric) aiming for 150-200 per person can change the outcome of entire teamfights.

✓ Do's

  • Prioritize targets with high resistances (Armor/MR) to maximize the "Effective Health" of your heals.
  • Watch for the Grievous Wounds icon (a broken red heart) on your allies before casting your biggest heals.
  • Combine Heal/Shield Power items with Ability Haste to increase your total healing over time (HPS).

✗ Don'ts

  • Don't waste your biggest heal (like Soraka R) when an ally is affected by ignite/60% Grievous Wounds if you can wait 2 seconds.
  • Don't ignore your own health—many healers (like Soraka) sacrifice their own HP to heal others.
  • Don't overbuy only AP if you are a support; % Heal Power is often more gold-efficient for raw sustain.

How It Works

The League of Legends Healing Calculator is the definitive tool for players of Soraka, Yuumi, Nami, and other sustain-focused champions. Healing wins wars of attrition in LoL, keeping your carries alive through heavy poke and long teamfights. This tool calculates your raw healing numbers and then applies modifiers like Grievous Wounds (Healing Reduction) to show you how much health you are actually restoring in the heat of battle.

Understanding the Inputs

Base Heal: The flat number in your spell tooltip. AP: Total Ability Power. Heal Power %: Sum from items and Revitalize. Grievous Wounds: Set to 40% if the enemy has anti-heal items.

Formula Used

Final Heal = (Base + Scaling) × (1 + Item HSP / 100) × (1 - Grievous Wounds %) × (1.25 if Spirit Visage) × (1.05 if Revitalize) Scaling = (AP × Ratio) + (Max HP × Ratio)

Real Calculation Examples

  • 1A Soraka with 300 AP casting Level 5 W (170 Base + 50% AP) with 30% Heal Power: (170 + 150) * 1.3 = 416 Total Healing.
  • 2A Vlad using Q on a target while affected by 40% Grievous Wounds: His healing is cut nearly in half, regardless of his AP scaling.
  • 3A Yuumi attached to a Mundo with Spirit Visage (+25% healing received): Her heals receive a massive multiplicative boost from the targets own passive stats.

The Comprehensive Guide

League of Legends Healing Guide: Mastering Sustainable Combat

Healing is one of the most polarizing and powerful mechanics in League of Legends. A single Soraka W or Nami Ebb and Flow can be the difference between a successful tower dive and a triple kill for the enemy. This guide explores the intricate math of Healing Scaling, the impact of Grievous Wounds, and how to build the ultimate sustain engine.

The Foundation of Healing Math

In LoL, every healing ability follows a standard path from your stats to the target's health bar. Understanding this path allows you to choose the right items for your specific champion.

1. Base Values and Ability Rank

Most heals gain 30-50% more base power just from leveling up the skill from Rank 1 to Rank 5. This is why healers like Soraka or Yuumi prioritize maxing their primary heal first—it is the most stable increase in power you can get.

2. Scaling Ratios (AP and HP)

Almost all active heals in the game scale with Ability Power (AP). Typical ratios range from 30% to 70%.
- Example: If Nami has 100 AP and a 50% ratio, she restores 50 bonus health.
- Advanced: Some champions like Taric or Alistar scale with health, making them "Tank Healers" who get stronger as they build more durability.

The Multiplier: Heal and Shield Power

For enchanters, the "Heal and Shield Power" stat is the single most important purchase. Unlike AP, which is additive, this stat is multiplicative. It increases the final number of your heal. If you have +20% Heal Power, a 500 HP heal becomes 600 HP.

Golden Rule: In the early game, buy AP for flat scaling. In the mid-to-late game, buy % Heal Power to multiply your already high base stats and AP ratios.

Grievous Wounds: The Great Equalizer

If healing were unchecked, games would never end. Grievous Wounds (Anti-Heal) is the mechanic Riot uses to keep sustain in check.
- 40% Reduction: This is the standard amount found on items like Thornmail, Mortal Reminder, Morellonomicon, and the Ignite summoner spell.
- How it acts: It is applied at the very end of the calculation.
Formula: Actual Healing = Calculated Healing × 0.60.

The "Spirit Visage" Effect

While healers build stats to heal others, tanks build stats to receive healing. Spirit Visage is the legendary counter-part to Grievous Wounds.
It provides a +25% increase to all incoming healing. If you are a Soraka healing a Mundo with Spirit Visage, your heal is amplified by 25% for free. This is why "Enchanter + Tank" duos are so hard to kill in the late game.

Runes for the Master Healer

If you want to maximize your sustain output, your rune page should look like this:

  • Revitalize (Resolve): The premier healing rune. It gives you 5% heal power permanently and a massive 10% extra (15% total) when healing a target below 40% HP. This is essential for surviving burst damage.
  • Aery (Sorcery): While mainly for damage, Aery provides a "shield" when you heal an ally, adding a layer of mitigation on top of your sustain.
  • Font of Life (Resolve): Imparing an enemy marks them; allies heal when they attack that enemy. This is "Passive Healing" that scales with your Max HP.

Core Itemization for HPS (Heals Per Second)

  1. Moonstone Renewer: The undisputed king of teamfight healing. It causes your abilities to chain heals to allies and increases your heal/shield power as you remain in combat.
  2. Ardent Censer: Best for healing ADCs. It provides heal power and gives your ally Attack Speed and extra on-hit damage.
  3. Redemption: A massive area-of-effect heal that can be used even while you are dead! It provides high base healing and 15% Heal/Shield power.
  4. Mikael's Blessing: Adds a cleanse and massive % bonuses, great for saving an ADC from a key CC spell while restoring their health.

Strategies: How to Out-Heal the Damage

1. Effective Health Synergy

Don't just heal based on the percentage of the bar. Heal the person who is currently being hit and has the highest resistances. Armor and Magic Resist make every 1 HP you restore "heavier" for the enemy to remove.

2. Anti-Heal Baiting

If an enemy has Ignite, wait for the Ignite to fade (5 seconds) before using your biggest heals unless the ally will die immediately. Using a 500 HP heal while ignited results in 200 health being wasted in the void.

3. The "Cooldown Cycle"

Healers like Sona or Soraka rely on Ability Haste. If you heal for 100 every 2 seconds, you are doing 50 HPS. If you get enough Haste to heal for 100 every 1 second, you have doubled your efficiency without buying a single point of AP.

Champion Deep Dive: Soraka, the Starchild

Soraka is the "Raw Healing" benchmark. Her W has a tiny cooldown (under 2 seconds) and a solid AP ratio. However, she pays with her own life (10% max HP per cast).
Pro Strategy: Hit your Q (Starcall) first! Hitting an enemy with Q gives Soraka the "Rejuvenation" buff, which causes her W to NOT consume health and grants the ally she heals extra health-per-second regen. Use our calculator to see how much Rejuvenation adds to your total output!

Advanced Tip: Healing as Mitigation

Often, healing is better than a shield because it is permanent. If an enemy pokes your ADC for 200 damage, and you heal them for 200, the enemy has essentially used their mana and cooldown for zero net gain. This is how healers "win lanes"—not by killing, but by exhausting the enemy's resources.

Verdict: Is Healing OP?

Healing is often called "anti-fun" because it negates plays. However, it requires precise mana management, expert positioning (since healers are usually squishy), and the ability to track Grievous Wounds durations. When a healer and their carry are in sync, they become a raid boss that requires an entire team to focus down.

Conclusion

Understanding the League of Legends Healing Calculator is your ticket to the high ranks of support play. Whether you are timing a Redemption to save your frontline or building 400 AP on Yuumi to turn your ADC into an unkillable god, the math is your greatest ally. Respect the anti-heal, build your multipliers, and keep your teammates in the game! See you on the Rift!

The Evolution of Anti-Heal Items

Years ago, anti-heal was rare. You had to buy a full Executioner's Calling or a Morellonomicon. Today, every class has a cheap 800-gold anti-heal option (Bramble Vest, Oblivion Orb, Executioner's). This has fundamentally changed how healers play. You can no longer rely on "out-healing" everything; you must now play around windows where anti-heal isn't being applied.

Ocean Drake: The Passive Sustain

The Ocean Drake provides health regeneration based on missing health. While not an "ability," it stacks with your active heals. Securing Ocean Soul is essentially giving every member of your team a "Passive Healer" that never runs out of mana. Calculating the total EHP of a team with Ocean Soul vs. a team with 40% Grievous Wounds show that Soul almost always wins out.

Support Item Priority List

  • Against Burst: Locket of the Iron Solari (Shields)
  • Against Poke: Moonstone Renewer (Sustain)
  • For Aggression: Ardent Censer (Buffs)
  • For Utility: Mikael's Blessing (Cleanse)

Frequently Asked Questions

Usage of This Calculator

Who Should Use This?

Support mains, theorycrafters looking for the "Best Sustain Build," and players trying to understand why their heals "feel weak" against anti-heal items.

Limitations

This calculator assumes standard ability scaling. It does not account for specific champion passives that might grant "Greener Health" or delayed healing (like Bard shrines).

Real-World Examples

The Soraka Miracle

Scenario: Soraka has 200 AP, 20% Heal Power, and uses Level 5 W (170 + 50% AP). Target is at 20% health.

Outcome: Base = 170 + 100 = 270. With 20% power = 324. If she has Revitalize (+10% extra), final heal = 356.4 HP.

The Anti-Heal Struggle

Scenario: A Nami heals her ADC for a calculated 200 HP. The enemy has Chempunk Chainsword (40% Reduced Healing).

Outcome: Actual HP restored: 200 * 0.6 = 120 HP. This deficit often forces the Nami to cast two heals instead of one, doubling her mana cost.

Summary

The LoL Healing Calculator helps you master the art of sustain. By understanding the interaction between your stats and the enemy's anti-heal efforts, you can optimize your build and keep your team in the fight for as long as it takes to secure the victory.
