Rolling a Saving Throw instead?

Skill checks (ability checks) are different from saves. Use the D&D 5e Saving Throw Roller for STR/DEX/CON/INT/WIS/CHA saves vs spell save DCs.

How Skill Checks Work in D&D 5e

A skill check is a simple test: roll a d20, add your skill modifier, and compare the result against a Difficulty Class (DC). This page lets you roll instantly with advantage/disadvantage and see a clean breakdown.

Core formula

d20 + skill modifier vs DC
  • DC is the target number set by the DM (higher DC = harder task).
  • Modifier usually comes from an ability modifier + proficiency bonus (if proficient).

Advantage & disadvantage

  • Advantage: roll 2d20 and take the higher result.
  • Disadvantage: roll 2d20 and take the lower result.

Common examples

  • Perception: spot a hidden lever, trap, or enemy movement in a noisy room.
  • Stealth vs passive Perception: sneak past a guard — your roll is compared to the guard’s passive score.
  • Athletics / Acrobatics: jump a gap, climb quickly, resist being shoved, or escape a grapple.

DM tips

  • Call for a roll only when failure has a consequence.
  • Use passive checks for repeated actions (like watching a hallway for minutes).
  • Keep DCs consistent so players learn what “hard” looks like at your table.

How to Use the Skill Check Calculator

  1. Choose a skill such as Acrobatics, Investigation, or Stealth. The calculator automatically displays which ability modifier the skill uses.
  2. Enter your ability modifier, proficiency bonus, and any extra bonuses (guidance, magic items, etc.).
  3. Select whether you are proficient or have expertise, and decide if the roll uses advantage or disadvantage.
  4. Press Roll Skill Check or tap the space bar to roll a d20, add modifiers, and see if you meet the DC.
  5. Optional: calculate passive skill (10 + modifiers) to compare against traps or hidden creatures.

Quick Rules Recap

  • Roll: d20 + modifier vs a DC set by the DM.
  • Advantage/Disadvantage: roll 2d20 and take the higher/lower.
  • Proficiency: add your proficiency bonus if proficient; with Expertise, double your proficiency bonus for that skill.
  • Passive: typically 10 + modifiers (often used for Perception/Investigation).

Features for Players and DMs

  • All 18 skills: Acrobatics through Survival with automatic ability references.
  • Proficiency/Expertise toggles: Adds proficiency or doubles it for rogues/bards.
  • Advantage/Disadvantage: Roll two d20s and keep the higher/lower automatically.
  • DC comparison: The summary displays success/failure instantly.
  • History + passive scores: View recent rolls and passive skill values for exploration scenes.

Examples and Tips

Example: a rogue with Dexterity +5, proficiency bonus +4, and expertise in Stealth rolls with a +13 modifier (plus any situational bonuses) and compares the total to a DC set by the DM. Use passive scores for repeated situations (like keeping watch), and keep the history panel open for contested checks. For combat flow, pair this with the attack roller and saving throw roller.
