| Accuracy | Turn | River | Turn+River | Comments |
| Excellent | Outs times 2.13% | Outs times 2.17% | *Turn odds plus River odds minus Turn odds times River odds | More accurate than you'll ever need |
| Very Good | Outs times 2-1/8% | Outs times 2-1/6% | **Outs times 4%, minus (Outs - 8) if 9 or more Outs | As accurate as you'll ever need |
| Good | Outs times 2%, plus 1% if 5+ Outs, plus 2% if 13+ Outs | Same as Turn | **Outs times 4%, minus (Outs - 8) if 9 or more Outs | The easiest reasonable approximation |
| Bad | Outs times 2% plus 1% | Same as Turn | Outs times 4% | Not good if low or high numbers of outs |
* For example, using the Good approximation, if you have 9 Outs, then you have a 19% chance on the turn, a 19% chance on the river, and a 38% minus 19% of 19% (close to 20% of 20%, which is 4%) equals a 34% chance on the turn and river combined.
