Darts Checkout Calculator for 501
The D-Artist darts checkout calculator is a free interactive finishing tool built specifically for competitive 501 players. Enter any score from 2 to 170 and instantly see the optimal checkout route, preferred miss direction, alternate finish, and a live dartboard highlighting exactly where to aim. Unlike a static darts checkout chart, this calculator updates in real time as you tap each dart result — so you always know your next move, even after a miss.
Most darts calculators show one route and stop. This tool gives you the full picture: primary checkout route, alternate finish, 2-dart out where available, setup shots for bogey numbers, and miss management guidance built from dartboard geometry. It is designed for players who want to understand why a checkout works — not just memorise a number off a chart.
How to Use the Darts Checkout Calculator
Type your remaining 501 score into the input field at the top of the tool. The darts calculator immediately displays the optimal checkout route and highlights the first target on the interactive dartboard. The miss grid below shows every surrounding number — tap any result to record a miss and the calculator instantly recalculates your new score and updates the recommended route for your next dart.
Where an alternate checkout exists, an ALTERNATE — tap to use link appears below the primary route. This lets you switch to a preferred double mid-throw or choose a route that better suits your throwing style under match pressure. The calculator tracks your session dart by dart, so it functions as both a reference tool and a live checkout trainer during practice.
2-Dart Finishes in 501 Darts
The highest 2-dart finish in 501 is 110 — treble 20 followed by the bullseye. All even scores from 2 to 40 can be finished with a single dart followed by a double. Scores such as 50 (bull), 76 (T20, D8), 82 (bull, D16), 85 (25, D20), 100 (T20, D20), and 104 (T18, Bull) are also 2-dart finishes. The calculator identifies every 2-dart out automatically and flags it with a green indicator so you never miss the opportunity to close a leg in two.
Knowing your 2-dart finishes is one of the fastest ways to improve your winning percentage in 501. When a leg reaches a 2-dart score, the pressure shifts entirely onto your opponent — and players who recognise these positions convert more legs than those who treat them as ordinary 3-dart scores.
3-Dart Checkouts: Route Selection and Miss Planning
For 3-dart checkouts, route selection matters as much as accuracy. The standard approach is to play a treble to reduce the score, then a second dart to set up a clean double. The most common 3-dart routes finish on D16, D20, D18, or the bullseye — doubles that sit on reliable parts of the board and offer good recovery options when the first or second dart misses.
Consider 81 — the standard route is T19, D12. The reason T19 is preferred over T20 is dartboard geometry: a miss inside T19 (hitting the 7 segment) leaves 74, which has a clean finish on T14, D16. A miss inside T20 from 81 leaves 61 — a much harder position. This kind of geometry analysis is built into every route this calculator recommends, for every score from 61 to 170.
Bogey Numbers in Darts
The bogey numbers in 501 darts are scores that cannot be finished in three darts: 169, 168, 166, 165, 163, 162, and 159. When you are on a bogey number, no combination of three darts — trebles, doubles, singles, or bull — can reach exactly zero. Players on bogey numbers must play a setup shot on the first visit and aim to finish on the next.
The correct setup for each bogey number is specific. From 169, the standard setup is T20, T19, leaving 32 (D16) for the next visit. From 168, T20, T20 leaves 28 (D14). Getting bogey number strategy right is one of the fastest gains available in competitive 501, because leaving the wrong score from a bogey number hands the leg to your opponent. This calculator shows the correct setup shot for every bogey number automatically.
Preferred Miss Direction and Dartboard Geometry
Every segment on a dartboard is flanked by two different numbers. Treble 20 sits between 1 and 5. Treble 19 sits between 7 and 3. Where your dart misses is not random — and where you intend it to miss should not be random either. The principle of miss direction means deliberately biasing your throw toward the side of a segment that leaves the most useful recovery score if the dart lands off-target.
From a score of 92, the standard route is T20, D16. If you miss T20 to the right, you hit 5, leaving 87 — a difficult three-dart position. If you miss T20 to the left, you hit 1, leaving 91 — still a clean finish on T17, D20. So the correct throw on T20 from 92 is biased left. This calculator displays the preferred miss direction for the first dart of every checkout route, so players can make this decision before they throw rather than reacting to a miss after the fact.
The same logic applies to doubles. D16 is widely considered the best finishing double in 501 not only because it is large, but because a miss inside leaves 16, then you aim D8; miss inside again leaves 8, then D4; then D2; then D1. Every miss on D16 stays on a double. No other segment on the board offers that halving chain. The calculator accounts for this when recommending finishing doubles.
501 Darts Checkout Chart — Common Finishes
The most frequently encountered checkout scores in competitive 501 are listed below with the recommended route and the reason it is preferred over alternatives.
170 — T20, T20, DBull. The maximum three-dart checkout in 501, known as the Big Fish. Requires two perfect treble 20s followed by the bullseye.
167 — T20, T19, DBull. The highest finish reachable without two T20s.
160 — T20, T20, D20. The highest non-bull three-dart finish.
121 — T20, T11, DBull. Standard bull finish from a common score. Alternate: T17, D20, D20 via a different setup.
110 — T20, DBull. The highest 2-dart finish in darts. Miss T20 inside and you face a harder position — aim left of T20.
100 — T20, D20. The cleanest 2-dart finish. A benchmark score every competitive player should close without hesitation.
96 — T20, D18. Missing T20 inside leaves 76, still finishable. D18 is a reliable double with a good miss pattern.
92 — T20, D16. Bias left on T20. Miss to 1 leaves 91 — still a solid 2-dart position.
81 — T19, D12. Preferred over T20, D21 (not valid) or T15, D18. T19 geometry is kinder on misses.
76 — T20, D8. Missing T20 inside leaves 56 — still a clean 2-dart finish.
65 — 25, D20. Single bull then double tops. The simplest 2-dart out for an odd score below 70.
40 — D20. Direct double tops. The most hit finishing double on the PDC tour.
32 — D16. The most reliable finishing double in 501. Miss inside and halve down indefinitely.
Darts Calculator vs a Checkout Chart
A printed darts checkout chart shows one route per score. It cannot tell you what to do after a miss, cannot adjust for your current score mid-leg, and cannot flag bogey numbers or 2-dart finishes dynamically. A darts checkout calculator does all of this. The D-Artist calculator goes further by adding miss direction guidance and live dartboard visualisation — features no static chart can offer.
For players learning checkouts, a chart is a useful starting point. For players competing at any level above casual pub darts, a calculator that responds to misses and updates in real time is the correct tool. The D-Artist darts calculator is free, works in any browser, and requires no download or account.

Darts Checkout Calculator — Frequently Asked Questions
The highest checkout in darts is 170, finished with T20, T20, Bull. It requires two perfect treble 20s followed by the bullseye and is known as the Big Fish. It is the maximum three-dart finish possible in a 501 double-out game. The next highest checkouts are 167 (T20, T19, Bull) and 164 (T20, T18, Bull).
The bogey numbers in darts are scores that cannot be finished in three darts: 169, 168, 166, 165, 163, 162, and 159. No combination of three darts — including trebles, doubles, singles, and bull — can reach exactly zero from these scores. When you land on a bogey number, you must play a setup shot on your current visit and aim to finish on the next. The darts calculator shows the correct setup for each bogey number automatically.
D16 is widely considered the best finishing double in 501. The reason is the halving chain — if you miss D16 inside and hit single 16, you are left on 16 and aim D8. Miss D8 inside and you face D4, then D2, then D1. Every miss stays on a double. No other segment on the dartboard offers this self-correcting property. D20 is the most frequently hit finishing double on the PDC tour due to its position at the top of the board, but D16 is the strategic choice for players managing misses.
The standard 81 checkout in darts is T19, D12. The reason T19 is preferred over alternatives is dartboard geometry — a miss inside T19 (into the 7 segment) leaves 74, which finishes cleanly on T14, D16. Missing inside T20 from 81 leaves 61, a much harder position to recover from. The D-Artist darts checkout calculator displays this geometry analysis for every score from 61 to 170.
Preferred miss direction is the principle of biasing your throw toward the side of a target that leaves the most useful recovery score if the dart misses. For example, from 92 (T20, D16), a miss left on T20 hits the 1 segment, leaving 91 — a clean 2-dart position. A miss right hits the 5 segment, leaving 87 — a harder score. So the correct throw on T20 from 92 is deliberately biased left. This principle is built into every route recommendation in the D-Artist darts calculator.
The highest 2-dart finish in darts is 110 — T20 followed by the bullseye. Other common 2-dart finishes include 100 (T20, D20), 104 (T18, Bull), 85 (25, D20), 82 (Bull, D16), 76 (T20, D8), and all even scores from 2 to 40. The darts calculator highlights every 2-dart finish automatically so you never miss the chance to close a leg in two visits.
A darts checkout calculator takes your remaining 501 score and returns the optimal sequence of throws to reach exactly zero, ending on a double or the bullseye. The D-Artist calculator shows the primary checkout route, an alternate finish where one exists, the preferred miss direction for each target, and live dartboard geometry. When a dart misses, you tap the result and the calculator immediately recalculates your new score and updates the recommended route — so it functions as both a reference tool and a live practice trainer.
The standard 121 checkout in darts is T20, T11, DBull. It is one of the most commonly encountered bull finishes in competitive 501 and requires precise execution on all three darts. An alternate route is T17, T10, D20 for players who prefer to avoid the bull. The D-Artist darts calculator shows both routes and indicates the preferred miss direction for the first dart.
