D&D 5e Fall Damage Calculator

Instantly calculate falling damage based on official 5e rules, including optional rules from Tasha’s Cauldron of Everything and class features.

What is the Fall Damage Calculator 5e?

A fall damage calculator 5e is a specialized tool for Dungeon Masters and players of Dungeons & Dragons 5th Edition to quickly determine the consequences of falling. According to the Player’s Handbook, fall damage is a common hazard. This calculator simplifies the core rule: 1d6 bludgeoning damage for every 10 feet fallen, to a maximum of 20d6. It also incorporates advanced scenarios, such as the effects of the Feather Fall spell, a Monk’s Slow Fall ability, and the optional rule from Tasha’s Cauldron of Everything for falling onto another creature. Anyone playing D&D 5e, especially DMs who need to make quick rulings during combat or exploration, will find this tool invaluable. A common misunderstanding is how damage caps; this calculator correctly limits the damage dice to 20d6, regardless of how extreme the fall height is.

The Fall Damage 5e Formula and Explanation

The fundamental formula for fall damage in D&D 5e is straightforward and designed for ease of use rather than perfect physics simulation.

Damage Dice = min(20, floor(Fall Distance / 10))

This means for every full 10 feet a creature falls, you add one d6 to the damage roll. This continues until you reach 200 feet, where the damage caps at 20d6. A fall of 9 feet results in no damage, while a fall of 19 feet results in 1d6 damage. A fall from 500 feet still only results in 20d6 damage. Unless the creature avoids taking damage from the fall, it lands prone.

Variables Table

Key variables used in calculating fall damage.

Variable	Meaning	Unit / Type	Typical Range
Fall Distance	The height from which the creature falls.	Feet	10 – 500+
Damage Dice	The number of six-sided dice (d6) rolled for damage.	d6s	1 – 20
Damage Reduction	A flat amount subtracted from the total rolled damage.	Hit Points	Varies (e.g., 5 x Monk Level)
Landed Prone	The condition of the creature after landing.	Boolean	True or False

Practical Examples

Example 1: A Simple Fall

• Inputs: A Rogue attempts to leap across a 20-foot chasm and fails, falling 40 feet to the jagged rocks below.
• Calculation: 40 feet / 10 = 4. The damage is 4d6.
• Results: The Rogue takes 4d6 bludgeoning damage and lands prone. Using our fall damage calculator 5e, this gives a max damage of 24 and an average of 14.

Example 2: A Monk’s Graceful Tumble

• Inputs: A Level 9 Monk is pushed off a 100-foot cliff. The Monk uses their Slow Fall reaction.
• Calculation: The initial damage would be 10d6 (from 100 feet). The Monk can reduce this damage by an amount equal to five times their monk level (5 * 9 = 45). Let’s say the DM rolls 10d6 and gets a total of 38. The Monk reduces this by 45, bringing the damage taken to 0.
• Results: The Monk takes 0 damage. Because they avoided taking damage, they do not land prone. This showcases a key benefit available in our Monk class guide.

How to Use This Fall Damage Calculator 5e

1. Enter Fall Distance: Input the total distance fallen in feet. The calculator automatically determines the base damage dice.
2. Select Special Conditions: Check the box if the creature has an ability like Feather Fall or a Monk’s Slow Fall. This will reveal further options.
3. Specify Reduction Type: If an immunity or reduction is active, choose the correct type. For a Monk, you’ll need to enter their level for an accurate calculation.
4. Use Tasha’s Rule (Optional): Check the ‘Falling Onto Another Creature’ box if you are using this optional rule from Tasha’s Cauldron of Everything. The calculator will note that the damage may be halved.
5. Interpret Results: The calculator provides the damage dice (e.g., “8d6”), the maximum and average damage, and notes about damage reduction or splitting. This is far quicker than checking the d&d 5e rules compendium every time.

Key Factors That Affect Fall Damage in 5e

• Feather Fall Spell: A 1st-level spell that can negate all fall damage for up to five creatures if they land before the spell ends. It’s a must-have for any party exploring high places.
• Monk’s Slow Fall: This class feature allows a Monk to use their reaction to reduce fall damage by five times their Monk level, often negating it entirely.
• Resistance to Bludgeoning Damage: Creatures with resistance (like a Barbarian raging) take half damage from the fall after the dice are rolled.
• Falling Onto a Creature: An optional rule from Tasha’s Cauldron of Everything states that if you fall on another creature, they must make a DC 15 Dexterity save. On a failure, the damage is split evenly between both, and both are knocked prone. On a success, only the falling creature takes damage.
• Rate of Falling: Xanathar’s Guide to Everything introduces an optional rule that a creature falls 500 feet instantly in a round. This is relevant for casting reaction spells like Feather Fall. You can find more details in our guide to calculating movement and speed.
• Immunity: Some creatures, particularly those with a flying speed who can hover, may be naturally immune to fall damage. A DM might also rule that landing in deep water or another soft surface could reduce or negate the damage.

Frequently Asked Questions (FAQ)

What’s the maximum fall damage in 5e?

The maximum damage is 20d6, which occurs from a fall of 200 feet or more. Any fall greater than 200 feet still only results in 20d6 damage.

Do you take fall damage in water?

The rules as written don’t specify an exception for water. Most DMs will house-rule that falling into deep water from a great height might reduce or negate the damage, but this is a DM’s call.

How does a Monk’s Slow Fall work?

Starting at 4th level, a Monk can use their reaction when they fall to reduce the damage by an amount equal to 5 times their Monk level. For example, a 10th-level Monk reduces fall damage by 50.

What does the Feather Fall spell do?

It’s a reaction spell that slows the rate of descent for up to five creatures. If they land before the spell’s 1-minute duration expires, they take zero damage and land on their feet. This is a crucial spell detailed on our Feather Fall spell page.

What are the “Tasha’s falling rules”?

This refers to the optional rule in Tasha’s Cauldron of Everything for falling onto another creature. It provides mechanics for splitting damage and knocking creatures prone.

Do you land prone after falling?

Yes, unless you take zero damage from the fall (e.g., through Feather Fall or Slow Fall), you land prone.

How does this calculator handle a Monk’s damage reduction?

The fall damage calculator 5e subtracts the Monk’s reduction (Level x 5) from the *average* and *maximum* potential damage, giving you a clear idea of the likely outcome before you roll the dice.

Can I use this fall damage calculator 5e for older editions?

No, this calculator is specifically designed for the D&D 5th Edition ruleset. Other editions have different, often more complex, rules for falling.
