Formula Used
The calculator first converts displayed attack to true raw when needed.
True raw equals displayed attack divided by the selected weapon multiplier.
Effective true raw = (true raw + flat raw bonus) × (1 + raw bonus percent ÷ 100).
Average raw critical factor = 1 + affinity rate × critical gain.
Positive affinity uses the selected critical multiplier.
Negative affinity uses the weak hit multiplier.
Raw damage = effective true raw × motion value × raw sharpness × raw hit zone × average critical factor × quest modifier × rage modifier × defense modifier × special modifier.
Element damage = effective element × element sharpness × element hit zone × element critical factor × element modifier × quest modifier × rage modifier × defense modifier × special modifier.
Final combo damage equals raw damage plus element damage, multiplied by hit count.
The selected rounding rule is then applied.
Monster Hunter Damage Planning Guide
Why Damage Math Matters
Monster Hunter damage feels simple when a number appears on screen, yet many hidden factors shape that number.
A strong weapon can underperform when the hit zone is poor.
A modest weapon can shine when sharpness, affinity, and motion value align.
This calculator brings those parts together.
It gives a practical estimate before you spend time farming, crafting, or testing in the training area.
Raw Damage Choices
Raw damage starts with true raw.
Some games show inflated attack values, so the tool lets you divide displayed attack by a weapon multiplier.
Motion value then represents the strength of the move.
A slow charged slash has a large motion value.
A quick poke has a smaller one.
Sharpness, hit zone value, quest modifier, rage modifier, and extra multipliers then adjust the final raw estimate.
Element And Affinity
Element follows a separate path.
The calculator converts displayed element when needed, applies elemental sharpness, checks the monster part value, and adds optional elemental boosts.
Affinity is handled as an average value.
Positive affinity increases expected damage through critical hits.
Negative affinity lowers expected damage through weak hits.
Critical Boost can raise the value of positive critical hits.
Better Build Comparison
Use the result to compare sets, not to chase one perfect number.
Real hunts include movement, missed attacks, stagger timing, part breaks, and monster behavior.
A build with lower sheet damage may win when it keeps sharpness longer or reaches better hit zones more often.
Record several attacks from the same combo.
Then compare totals across weapons, charms, decorations, food, and buffs.
Reading The Output
The output separates raw, element, total damage, effective true raw, and average critical factor.
This makes problems easy to find.
If raw damage is low, check motion value or hit zone.
If element is low, check the elemental hit zone.
If the critical factor is weak, review affinity.
Export the result as a CSV or PDF for build notes, guides, team planning, or repeat testing.
Keep every test consistent.
Use the same monster part, sharpness level, food buff, and rage state.
Small changes can hide the real winner, especially when two builds are close in performance during long hunts.
FAQs
What is true raw?
True raw is the real attack value used in most damage formulas.
Some games show inflated weapon attack.
Divide displayed attack by the weapon multiplier to estimate true raw.
What is motion value?
Motion value is the power rating of an attack animation.
Heavy attacks usually have higher motion values.
Fast attacks usually have lower values.
What does hit zone value mean?
Hit zone value shows how much damage a monster part accepts.
A higher value means the part is weaker.
Raw and elemental hit zones are often different.
How does affinity affect damage?
Affinity is critical hit chance.
Positive affinity raises average damage.
Negative affinity lowers average damage.
The calculator uses expected damage instead of random hit results.
Why is element calculated separately?
Element uses different hit zones and sharpness modifiers.
It is not based on motion value in this simplified model.
This separation helps compare raw and elemental builds.
Which rounding option should I use?
Use floor each hit when you want a stricter estimate.
Use no rounding for comparison work.
Game rounding can vary by title and damage step.
Can this match every game exactly?
No single web form can cover every title, patch, and hidden rule.
Use it as a flexible estimator.
Adjust modifiers to match your chosen game.
Why include CSV and PDF exports?
Exports help save build tests.
CSV works well for spreadsheets.
PDF is useful for notes, guides, and sharing results with a team.
