Formula Used
Raw heal per application = Base heal + Healing Power × Healing coefficient.
Positive multiplier = (1 + Outgoing %) × (1 + Incoming %) × (1 + Other %).
Final multiplier = Positive multiplier × Healing reduction factor × Barrier factor.
Total potential value = Modified heal per application × Pulses × Targets.
Effective value = Minimum of target missing health and target potential value, multiplied by targets.
How to Use This Calculator
Enter the healing source name first. Add the base heal and coefficient from your chosen skill, trait, or effect.
Enter your Healing Power. Add any temporary Healing Power bonus in the extra field.
Use pulses for repeated healing ticks. Use targets for group healing.
Add outgoing, incoming, and other healing modifiers as percentages.
Set missing health per target to estimate practical healing. Submit the form. Then download the report as CSV or PDF.

Why Healing Power Matters
Healing Power changes how support builds feel in Guild Wars 2. The value does not create one universal bonus. Each healing source has its own base amount and coefficient. That is why two skills can react very differently to the same stat increase. A pulse skill may look small, but many pulses and many allies can make it strong.
What This Tool Measures
This calculator separates the parts of the heal. It shows the base share, the Healing Power share, the modified value, the total group value, and the effective value after missing health. That last number matters. A huge heal can waste value when allies are already healthy. The overheal line helps you compare practical output, not only tooltip output.
Reading Coefficients Correctly
A coefficient tells you how much one point of Healing Power adds before modifiers. A coefficient of 0.80 means 1,000 Healing Power adds 800 healing to each single application. If the skill hits five allies, the group value becomes much larger. If the skill pulses three times, the total increases again. Modifiers then multiply the result.
Using Modifiers
Outgoing healing bonuses come from traits, runes, relics, sigils, food, and build effects. Incoming healing bonuses can come from the target. Some encounters may reduce healing. Enter those values as percentages. The calculator multiplies positive bonuses together, then applies the reduction. This makes stacking clearer than mental math.
Planning a Support Build
Use this tool while comparing gear sets. Keep the same base heal and coefficient. Change Healing Power and outgoing bonuses. Watch the gain from one hundred Healing Power. Then compare that with a five percent modifier. High coefficients like raw stats. Low coefficients often prefer broad modifiers. Group pulses also reward target count.
Practical Tips
Use realistic missing health values. A raid squad rarely needs full healing at every second. For strike missions and fractals, test both burst and steady settings. For World versus World, increase target count and pulses. Save the CSV or PDF after each test. You can build a small library of skill comparisons. Always record the skill patch date. Balance changes can shift coefficients, so confirmed values keep your comparisons useful for future updates and revisions.
FAQs
What does Healing Power do in GW2?
Healing Power increases healing when a skill, trait, or effect has a healing coefficient. The benefit is different for each source because each source can use a different base value and coefficient.
Why do I need the healing coefficient?
The coefficient shows how strongly a healing source scales with Healing Power. A higher coefficient means each point of Healing Power adds more healing before modifiers are applied.
Can this calculator handle pulsing heals?
Yes. Enter the number of pulses or applications. The calculator multiplies the modified value by that amount, then applies the target count for group healing.
What is outgoing healing bonus?
Outgoing healing bonus is a percentage increase to healing you apply. It may come from traits, runes, relics, food, or other build effects.
What is incoming healing bonus?
Incoming healing bonus belongs to the target receiving healing. Enter it only when the target has an effect that increases healing received.
Why is effective healing lower than potential healing?
Effective healing is limited by missing health. If a target only lacks 2,000 health, a 5,000 heal has 3,000 overheal for that target.
Can I estimate barrier with this tool?
Yes. Select the barrier mode and enter a barrier factor. This gives a planning estimate for barrier-style support calculations.
What should I enter for cooldown?
Enter the skill cooldown or your rotation window. The calculator uses it to estimate value per second for comparing burst and steady healing.
