Bridge Scoring:
It can be difficult to remember every possible score in bridge, but by using a formula every score can easily be calculated as set out below.
The following abbreviations are used here.
NV = Non Vulnerable, V = Vulnerable, ND = not doubled, X = doubled, XX = redoubled, OT=Overtrick.
SCORE = Tricks + Contract bonus + Overtricks + Game OR small slam OR grand slam bonus + Insult as applicable (TCOGI)
| TRICKS |
 20 each,
 30 each, NT 40 for first trick, 30 for others |
| CONTRACT MADE | 50 for ND and X, 100 for XX |
| OVERTRICKS Not Doubled |
20 each,
NT 30 each, |
| - Doubled | 100 per OT NV, 200 per OT V, |
| - Redoubled | 200 per OT NV, 400 per OT V. |
| Game: | NV = 250, V =450 |
| Small Slam: | NV = 500, V = 750 |
| Grand Slam: | NV = 1000, V =1500 |
| Insult: | 50 |
