How to Use the Darts Average Calculator
The three-dart average is the most important performance metric in darts. It tells you how efficiently you score across your throws, independent of lucky finishes or unlucky busts.
Step 1: Enter Your Leg Data
For each leg you play, record the starting score (501, 301, etc.) and the total number of darts you threw to win the leg. If you didn't win the leg (your opponent won), you can still calculate your partial average from how many darts you threw and what score you reached.
Understanding the Formula
Three-dart average = (total score closed × 3) ÷ total darts thrown. Example: Win 501 in 18 darts = (501 × 3) ÷ 18 = 1503 ÷ 18 = 83.5. Alternatively: Win 501 in 21 darts = 1503 ÷ 21 = 71.6.
Benchmark Averages
30–50: casual player. 50–70: regular club player. 70–90: competitive amateur. 90+: strong county-level player. 100+: professional standard. World championship level regularly sees averages of 105–115 or higher in televised matches.

What is a three-dart average?
The three-dart average is the primary performance metric in darts. It represents the average score per three darts thrown. Formula: (total points scored ÷ total darts thrown) × 3. Professional players average 100+ per 3 darts; recreational players typically average 30–70.
How do I calculate my darts average from a 501 leg?
For a 501 leg: your three-dart average = 501 ÷ (total darts thrown ÷ 3) × ... or more simply: average = 1503 ÷ total darts thrown. Example: finishing 501 in 18 darts = 1503 / 18 = 83.5 average.
What's a good three-dart average?
Amateur players: 30–50 average. Intermediate club players: 50–70. Strong club players: 70–90. County/state level: 90–100. Semi-professional: 95–105. Professional tour players: 100+. Phil Taylor's career average was over 100.
Can I track multiple legs?
Yes — add each leg with its starting score (501 or 301) and darts thrown. The calculator shows per-leg averages and cumulative average across all entered legs.
What's the difference between 501 and 301 average?
The same formula works for both — your average is the same regardless of starting score, since it's just total score ÷ total darts ÷ 3. A 501 leg won in 9 darts has the same 167.0 average as a 301 leg that's mathematically equivalent.
