Enter the total score and the scores of the first, second, and third darts into the calculator to determine the remaining score.

Darts Score Formula

The following formula is used to calculate the remaining score in a game of darts.

RS = TS - (D1 + D2 + D3)


  • RS is the remaining score after a turn

  • TS is the total score at the start of the turn

  • D1 is the score of the first dart thrown

  • D2 is the score of the second dart thrown

  • D3 is the score of the third dart thrown

To calculate the remaining score, start with the total score at the beginning of the turn. Subtract the score of the first dart, the score of the second dart, and the score of the third dart from the total score. The result is the remaining score after the turn. If the remaining score reaches exactly zero and the final dart is a double or the bullseye, the player wins the game. If the score goes below zero or ends on a number that cannot be finished with a double or bullseye, the score for that turn is invalidated, and the player’s score reverts to what it was at the start of the turn.

What is a Darts Score?

A darts score refers to the number of points a player accumulates by throwing small, pointed missiles, known as darts, at a circular target called a dartboard. Each section of the dartboard has a designated point value, with the outer rings generally doubling or tripling the score of the section hit, and the bullseye in the center offering a higher score. Players take turns throwing a set number of darts, typically three, and the score from each throw is subtracted from a predetermined total, often starting at 501 or 301. The objective is to reach exactly zero points before the opponent, with the final dart needing to land in a double segment or the bullseye to “check out” and win the game.

How to Calculate Darts Score?

The following steps outline how to calculate a Darts Score.

  1. First, determine the points scored in each throw.
  2. Next, determine the number of throws.
  3. Next, gather the formula from above = DS = Σ(points per throw).
  4. Finally, calculate the total Darts Score.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem :

Use the following variables as an example problem to test your knowledge.

Points scored in each throw: 20, 5, triple 20 (which equals 60), and a bullseye (50).

Number of throws: 4

Calculate the total Darts Score using the formula DS = Σ(points per throw).

Total Darts Score = 20 + 5 + 60 + 50

Total Darts Score = 135
