Initiative Order Calculator

Tabletop initiative order is determined by adding each combatant's d20 roll to their Dexterity modifier, then acting from highest total to lowest. This calculator does that math for up to five combatants at once and breaks ties by the higher DEX modifier -- the rule in D&D 3.5, 4th Edition, and Pathfinder 1e, and one of the most common house rules at 5e tables. Note that 5e as written does not use a DEX tiebreak: the Player's Handbook has the DM decide the order among tied monsters and the players decide among tied characters, with an optional d20 re-roll. If your table follows that, use this tool for the totals and settle ties yourself.

Leave a combatant's Roll at 0 to drop them from the encounter entirely -- they're excluded from the sort and don't count toward Active Combatants. The 1st through 5th Place Total outputs show the sorted totals themselves, not which combatant produced them, so pair this tool with your own notes on who's who. Raising any combatant's Roll or DEX Mod can only push that combatant's total up, which in turn can only raise or hold steady the highest total shown in 1st Place -- it never lowers it. Initiative Spread is simply the gap between the highest and lowest totals in the encounter, a quick read on how bunched together or spread out the turn order is this round.
