Detailed Guide Coming Soon
We're working on a comprehensive educational guide for the HPS (Healing Per Second) Calculator. Check back soon for step-by-step explanations, formulas, real-world examples, and expert tips.
The Healer Throughput (HPS) Calculator measures a healer's effective healing output per second, helping healers optimize their throughput, evaluate spell efficiency, and plan for healing-intensive encounters. HPS (Healing Per Second) is the primary metric for healer performance, analogous to DPS for damage dealers. Effective HPS differs from raw HPS by accounting for overhealing — healing applied to targets already at full health is wasted throughput. High raw HPS with 40% overheal is worse efficiency than moderate HPS with 10% overheal. Healer efficiency is more complex than DPS because it depends on both the healer's output and the damage intake of the group. A healer in a smoothly-running raid will have lower HPS than one in a chaotic run, but the former is actually playing better (proper cooldown usage means healing is not needed). The fundamental HPS formula is: Effective HPS = Total Healing Done / Fight Duration. Spell efficiency (healing per mana point) is equally important because healers have finite mana resources — a healer who runs out of mana mid-fight cannot sustain HPS regardless of throughput potential. The most mana-efficient heal is usually a slow but cheap heal like Healing Wave (WoW Shaman) or Physick (FFXIV). High-throughput emergency heals like Nature's Swiftness or emergency CDs have poor mana efficiency but are necessary for surge healing. In party vs. raid contexts, HPS requirements differ dramatically — a Mythic+ dungeon healer typically needs high single-target burst healing for tank damage, while a 20-person raid healer focuses on area healing mechanics and spreading efficient HoTs.
HPS = Total Healing Done / Fight Duration (seconds) Effective HPS = (Total Healing - Overhealing) / Fight Duration Mana Efficiency = Healing per Cast / Mana Cost per Cast Healing Required = Incoming Damage - Damage Absorbed
- 1Step 1: Collect total healing done and overheal data from a combat log parser.
- 2Step 2: Calculate effective HPS: (total healing - overheal) / fight duration.
- 3Step 3: Compare effective HPS to the incoming damage per second to identify gaps.
- 4Step 4: Audit individual spell efficiency — which spells have high overheal %?
- 5Step 5: Identify mana usage rate and compare to fight duration for sustainability.
- 6Step 6: Review cooldown timing — emergency CDs should be used reactively, not burned on minor damage.
A 30% overheal rate is typical for Holy Priest in a smoothly-progressing raid, where most players are near full health and heals land slightly over their HP. This is not necessarily poor performance — some overheal is unavoidable due to heal travel times and cast pre-queuing. If overheal exceeds 40%, the healer is casting unnecessarily or their spells are too slow to land before other healers fill the HP. Effective HPS of 28,000 is the number that matters for actual healing contribution.
FFXIV healers are designed to have significant downtime — the healer role is expected to deal damage (DPS) during periods when no healing is needed. A White Mage with 13,667 effective HPS is performing competently. However, if tank HP is stable throughout the fight, the healer should be casting Holy, Stone, or Glare (DPS spells) rather than over-healing, pushing their total contribution beyond pure healing metrics.
This healer will run out of mana 23 seconds before the fight ends without mana conservation. Solutions: use a mana potion (restores 50,000 mana) at the 2-minute mark to extend mana by 55 seconds; shift to more mana-efficient spells (Renew/Prayer of Mending instead of Greater Heal) for the final third; or pre-cast Innervate (if available) at the 60% fight mark. Identifying this in advance through calculation prevents emergency mana extinction mid-fight.
A raid with two healers where Healer A focuses tank and Healer B focuses raid should divide labor appropriately. If the tank experienced 3 dangerous HP spikes, Healer A's 10,000 sustained HPS was sufficient for baseline healing but required emergency cooldowns during spikes. Analyzing which spikes correlated with specific encounter mechanics helps pre-plan cooldown assignments for future attempts.
Professionals in health and medical use Healing Per Second as part of their standard analytical workflow to verify calculations, reduce arithmetic errors, and produce consistent results that can be documented, audited, and shared with colleagues, clients, or regulatory bodies for compliance purposes.
University professors and instructors incorporate Healing Per Second into course materials, homework assignments, and exam preparation resources, allowing students to check manual calculations, build intuition about input-output relationships, and focus on conceptual understanding rather than arithmetic.
Consultants and advisors use Healing Per Second to quickly model different scenarios during client meetings, enabling real-time exploration of what-if questions that would otherwise require returning to the office for detailed spreadsheet-based analysis and reporting.
Individual users rely on Healing Per Second for personal planning decisions — comparing options, verifying quotes received from service providers, checking third-party calculations, and building confidence that the numbers behind an important decision have been computed correctly and consistently.

What is a good HPS for my role and content?
HPS benchmarks depend on content and group composition. Mythic+ dungeons typically require 15,000-30,000 effective HPS from a single healer at high keystone levels. Raid healing varies by fight type: healing-intensive fights (Healing Mythic raid bosses) may require 40,000+ EHPS, while easier fights may only need 15,000. Check WarcraftLogs or FFLogs for median and 75th-percentile EHPS for your specific boss and role to establish realistic benchmarks.
What is the best way to reduce overheal?
Reducing overheal requires better timing and reactive healing habits. Key strategies: use HoT-based healing (Rejuvenation, Renew) that heals gradually and is less likely to overheal than burst heals; pre-cast slower heals only when targets are below 70% HP; use weaker, more frequent heals instead of large infrequent heals; communicate with co-healers to avoid simultaneously healing the same target. Combat log analysis (WarcraftLogs spell breakdown) identifies which specific spells have the highest overheal rates.
When should I use healing cooldowns?
Healing cooldowns (Tranquility, Divine Hymn, Spirit Link Totem) should be used proactively when you know a major damage event is incoming, not reactively when multiple players are already near death. Most raid encounters have predictable high-damage windows (timer-based abilities, phase transitions) that allow pre-planning cooldown usage. Burning cooldowns on minor damage that self-resolves wastes their potential for critical moments. Coordinating cooldown assignments with other healers ensures maximum coverage without doubling up.
How does Absorb (shielding) affect HPS metrics?
Absorb shields prevent damage before it reaches health bars — they do not appear as 'healing done' in the same way. WarcraftLogs tracks absorbed damage separately from healing done. Discipline Priests and MW Monks have significant absorb components that make their raw HPS appear lower than Holy/Resto specs despite equivalent or superior effective contribution. When comparing healers, always include absorbs in the effectiveness assessment.
Should healers deal damage (DPS) when not healing?
Yes — in modern MMO design, healers are expected to deal damage during low-incoming-damage periods. A healer who exclusively casts heals (even efficient ones) when the group is at full HP is wasting potential contribution. FFXIV specifically designs healer kits with the assumption that 30-40% of a healer's output is DPS during safe periods. WoW healers similarly benefit from spending low-damage phases on damage abilities to contribute to kill timers, especially in Mythic+ where DPS race is critical.
How does tank behavior affect healer HPS requirements?
Tanks that use all their defensive cooldowns effectively and maintain appropriate mitigation dramatically reduce the healer's HPS requirements. A tank who forgets to use Shield Wall or Survival Instincts at critical moments forces the healer into emergency healing that consumes more mana and may not succeed. Strong healer-tank communication about cooldown timing (calling defensives before predictable large hits) is one of the most impactful improvements available to any group.
What parsers should I use to analyze my healing performance?
WarcraftLogs is the premier WoW healing analysis tool, showing detailed breakdowns of every spell cast, heal amount, overheal, and timing relative to encounter events. FFLogs serves the same function for Final Fantasy XIV. Both allow filtering by fight phase, comparing to percentile benchmarks, and identifying specific moments where healing was insufficient. Regular log review is the fastest path to improving healer decision-making and identifying which spells contribute most to effective throughput.
Pro Tip
After every raid attempt, review your spells' overheal percentage in WarcraftLogs. If any spell has over 40% overheal, cast it less frequently or replace it with a more reactive spell in that situation. Target 15-25% total overheal as a sign of efficient spell selection and timing.
Did you know?
In World of Warcraft's early history (vanilla, 2004), healing was so inefficient that 40-person raid teams typically brought 8-10 dedicated healers just to sustain the group. Modern WoW's encounter design and healer kits allow 1 healer for 5-player content and 4-5 healers for 20-player raids — a dramatic efficiency improvement reflecting 20 years of healer kit design evolution.
