| Weapon | Attack | Motion | Sharpness | Affinity | Raw Hitzone | Use Case |
|---|---|---|---|---|---|---|
| Great Sword | 960 | 48% | White | 20% | 60% | Charged hit check |
| Long Sword | 660 | 35% | White | 40% | 55% | Spirit combo estimate |

Formula Used
True raw = displayed attack ÷ weapon bloat + raw bonus.
Raw damage = true raw × motion value × raw hitzone × sharpness × quest modifier × enraged modifier × other modifier.
Element damage = true element × element hitzone × element sharpness × element skill multiplier × active modifiers.
Expected hit = sum of each possible hit result multiplied by its probability.
Standard deviation = square root of all weighted squared differences from the expected hit.
DPS = expected hit × hit count ÷ combo duration.
How to Use This Calculator
Choose the weapon type first. Enter the attack value from your equipment screen, or switch to true raw mode.
Add motion value, hitzone values, sharpness, affinity, and critical boost level. Then enter elemental data if your weapon uses element.
Use quest, enraged, and other modifiers for special tests. Enter hit count and duration for combo damage and DPS.

Build Better Damage Estimates
Monster Hunter World damage is not one simple number. It is a stack of small modifiers. This calculator helps you place those modifiers in one clear view. It treats the build as a statistical model. You can compare normal hits, critical hits, weak hits, and average results. That makes the tool useful for planning weapons, sets, decorations, food buffs, and short combo tests.
Why The Inputs Matter
Displayed attack is only a starting point. Each weapon type uses a bloat value. The tool converts it to true raw before using motion value. Motion value describes the strength of the attack. Hitzone value describes how well the monster part receives that attack. Sharpness then changes the raw and elemental sides separately. Affinity controls the chance of critical or negative hits. Critical Boost changes the critical multiplier. Extra raw, quest modifiers, and enraged modifiers can also shift the result.
Statistical Damage View
A single strike can land as a normal hit or critical hit. Negative affinity can create a weaker hit. Because each outcome has a probability, the average hit is an expected value. The calculator also estimates spread with a standard deviation. A high standard deviation means the same move can vary more between attempts. Combo total and damage per second make longer tests easier to compare. This helps when two builds have similar averages but different reliability.
Practical Build Testing
Use the same monster part, motion value, and duration when comparing builds. Change one variable at a time. Try raw focused settings, then try elemental focused settings. Record the expected hit and DPS. Export the result when you want a clean note for later review. The example table gives safe starting values for common testing patterns. Real game results can still vary because of rounding, part breaks, ramping skills, coatings, ammo behavior, phials, and special move rules.
Advanced Planning Notes
The calculator is not a replacement for training area checks. It is a planning helper. Use it before farming materials or rebuilding sets. Save several outputs. Then compare averages, critical range, and elemental contribution. This simple workflow shows whether a change is truly stronger, or only looks stronger on the equipment screen during early build planning.
FAQs
What does displayed attack mean?
Displayed attack is the attack value shown on the weapon screen. The calculator divides it by the selected weapon bloat factor to estimate true raw damage.
What is motion value?
Motion value is the attack strength percentage for a move. Stronger attacks usually have higher motion values, while quick multi hit attacks often use lower values.
Why does affinity affect average damage?
Affinity is a probability. Positive affinity can create critical hits. Negative affinity can create weak hits. The calculator weights each outcome to estimate average damage.
Does sharpness affect element?
Yes. Sharpness has separate raw and elemental modifiers. The calculator applies both sides separately, then combines them into the final expected hit estimate.
Can this calculate combo damage?
Yes. Enter hit count and combo duration. The calculator multiplies expected hit damage by hit count, then divides by duration for damage per second.
What is standard deviation here?
Standard deviation shows damage spread from affinity outcomes. A higher value means more variation between hits. A lower value means steadier results.
Why are real game numbers different?
Real results may differ because of rounding, special move rules, monster state, coatings, ammo, phials, part changes, defense rules, or hidden modifiers.
What should I compare first?
Start with expected hit and DPS. Then compare low hit, high hit, raw contribution, elemental contribution, and standard deviation for a fuller build view.
