Darts score calculator
Your score
T = treble, D = double, Bull = 50 (the inner bull counts as a double), 25 = outer bull. Routes favour trebles of 20 and 19 and the doubles players like most: 20, 16 and 8.
Checkout chart, 170 to 2
Tap a score to see other ways out.
The darts checkout calculator gives you the finish for any score from 170 down to 2. Type what’s left and it shows the route most players go for, plus up to five others. 121 on three darts? T19, T16, D8. With two darts, it only shows outs you can actually hit with two. It’s free, and the full checkout chart sits underneath.
Darts score calculator: scoring a leg
Keeping score as well? The darts score calculator at the top runs a whole leg of 501, 301 or 701. Enter each dart (treble 20, double 16, miss) and it adds up the visit, applies the bust rules (below zero, left on 1, or finishing on anything but a double), and keeps your three-dart average. Once you’re on 170 or less, the checkout below updates to what you have left.
Darts checkout chart: how the routes are chosen
There’s more than one way out of most scores. The calculator ranks them the way players do:
- Fewest darts first. 100 is T20, D20 in two, so a three-dart route never comes first.
- Favourite doubles. D20, D16 and D8 come before the others, because missing D16 inside often leaves D8, and missing D8 leaves D4.
- Big trebles. T20 and T19 first, since that’s where players throw all day. T16 is a common third choice.
- Bull only when it has to be. 170 is T20, T20, Bull and nothing else will do. Where a double works just as well, the double gets picked.
Bogey numbers and the biggest finishes
170 is the highest checkout in darts. Seven scores under it can’t be finished in three darts at all: 169, 168, 166, 165, 163, 162 and 159. These are called bogey numbers, and leaving one is a mistake players try hard to avoid.
With two darts, the highest finish is 110 (T20, Bull). Below that, 109, 108, 106, 105, 103, 102 and 99 can’t be done in two. On 99 you need three darts: T19, 10, D16 or similar.
| Score | Usual finish |
|---|---|
| 170 | T20, T20, Bull |
| 167 | T20, T19, Bull |
| 160 | T20, T20, D20 |
| 141 | T20, T19, D12 |
| 100 | T20, D20 |
| 81 | T19, D12 |
| 64 | T16, D8 |
| 40 | D20 |
Why it matters for darts betting
Markets like “highest checkout” and “170 checkout in the match” depend on how often players get to big finishes. A 170 needs three perfect darts in a row, which even top players land rarely. When a bookmaker offers short odds on one being hit in a single match, think about how many attempts there will really be. Our implied probability calculator shows what a price is saying.
