How to Use the Dart Checkout Calculator
A checkout in darts means bringing your remaining score to exactly zero, with the final dart landing on a double (including the bullseye double worth 50). Finishing on a single or triple doesn't count - your turn just ends with points still on the board. This calculator takes your remaining score and finds valid checkout combinations, ranked by the fewest darts required.
For example, 170 is the highest checkout possible in darts, and it can only be finished with triple-20, triple-20, and the bullseye double (60 + 60 + 50). On the other hand, 159, 162, 163, 165, 166, 168, and 169 are "bogey numbers" - scores that cannot be reduced to zero on a double no matter which darts you throw, so you have to route through a different number first.
The calculator searches across all 62 possible dart values - triples, doubles, singles, the single bull, and the double bull - to find combinations that finish in one, two, or three darts. When multiple combos share the same dart count, up to four are shown so you can pick the one ending on a double you're confident hitting. If you're newer to darts, practicing wide, familiar doubles like D16 or D20 tends to build reliable checkout habits faster than chasing exotic combinations.
