This is not intended to be article quality at the moment.

1st/2nd/Club

Step Score = J * (floor(C/4)^2 + 1)

where

• C = combo count after step
• J = 300 if Perfect, 100 if Great, 0 otherwise

3rd

Official description of the scoring system: https://web.archive.org/web/20080604023941fw_/http://www.konami.jp/bemani/ddr/jp/am/ddr3rd/plan/score.html

Let the base score for step calculation be B = floor(1000000 / (N*(N+1)/2)) where N = number of steps in the song. Then for the kth step,

Step Score = J * (K * S + Q)

where

• B = 1000000
• S = floor(B / (N*(N+1)/2)
• J = 10 if Perfect, 5 if Great, 0 otherwise
• Q = B - S*(N*(N+1)/2) if the last step, 0 otherwise

4th

Step Score = J + 333 * C

where

• C = combo count after step
• J = 777 if Perfect, 555 if Great, 0 otherwise

5th

Step Score = J * (K * S + Q)

where

• B = 500000 * (1 + D)
• D = difficulty rating if not an edit, 7 if an edit
• S = floor(B / (N*(N+1)/2)
• J = 10 if Perfect, 5 if Great, 0 otherwise
• Q = B - S*(N*(N+1)/2) if the last step, 0 otherwise

At the end of the stage a bonus is applied:

• Grade Bonus = 10000000 for AAA, divide by 10 for each lower rating down to 100 for D, 0 for E
• Combo Bonus is accumulated per step:

Step Combo Bonus = C * J'

where

• C = combo count after step if life bar not empty, 0 otherwise
• J = 55 if Perfect, 33 if Great, 0 otherwise

DDRMAX

Step Score = J * (K * S) + Q

where

• B = 5000000
• S = floor(B / (N*(N+1)/2)
• J = 10 if Perfect/OK, 5 if Great, 0 otherwise
• Q = B - S*(N*(N+1)/2) if the last step, 0 otherwise

At the end of the stage a bonus is applied for each Groove Radar category.

DDRMAX2/Extreme

Step Score = J * (K * S) + Q

where

• B = 1000000 * D
• D = difficulty rating if not an edit, 5 if an edit
• S = floor(B / (N*(N+1)/2)
• J = 10 if Perfect/OK, 5 if Great, 0 otherwise
• Q = B - S*(N*(N+1)/2) if the last step, 0 otherwise

SuperNOVA

Step Score = 10000000 * J / (2*N)

where

• J = 2 if Marvelous/Perfect/OK, 1 if Great, 0 otherwise

Score is rounded down to nearest integer for output but fractions are retained internally.

SuperNOVA2 to 2014

Step Score =

• S if Marvelous
• S - 10 if Perfect
• S/2 - 10 if Great
• 0 otherwise

where

• S = 1000000 / N

Score is rounded down to nearest 10 for output but fractions are retained internally.

A

Step Score =

• S if Marvelous
• S - 10 if Perfect
• S * 0.6 - 10 if Great
• S * 0.2 - 10 if Good
• 0 otherwise

where

• S = 1000000 / N

Score is rounded down to nearest 10 for output but fractions are retained internally.
