Divide the score you used (starting score minus remaining score) by the number of darts you threw to get your per-dart average. Multiply that by 3 to get the standard three-dart average. For example, finishing 501 in 19 darts gives a per-dart average of 26.37 and a three-dart average of 79.1.
The three-dart average is the most widely used statistic in darts. It represents the average score you achieve per three darts thrown. Professional players typically average above 90, with the elite reaching 100+.
Yes. Simply enter your remaining score (the points still left on the board when your opponent finished) and your total darts thrown. The calculator subtracts your remaining score from the starting score to find the score you actually used, then calculates your average from that.
For recreational players, a three-dart average of 40–60 is typical. Club-level players often average 60–80, county-standard players around 80–95, and professional tour players regularly exceed 95–100+. A 180 checkout in 9 darts gives a perfect average of 180.
501 is the standard format used in professional darts (PDC, BDO) because it balances skill, strategy, and game length. Players start at 501 and must finish exactly on zero, typically ending on a double. Other formats like 301 are used in quicker games or local leagues.
The theoretical minimum to finish 501 is 9 darts — three maximums of 180 (540 total is too high, so it's actually achieved with scores like 180, 180, 141 checkout). This is called a nine-darter and is the most celebrated feat in darts.
Add up the total score used across all legs, then divide by the total number of darts thrown across all legs. Multiply by 3 for your overall three-dart average. This gives a more accurate representation of your performance over a full match.
Yes — the starting score determines how much you scored. If you're playing 301 instead of 501, the same number of darts will produce a different average. Always match the starting score to the format you actually played.
