How to Use This Calculator
  1. Enter total QSOs worked and unique multipliers (DXCC entities, states, zones, etc.).
  2. Set the QSO point value for your contest category (CW vs. phone, band, distance).
  3. Select the contest type to apply the correct scoring formula.
  4. Review your final score, total QSO points, QSO rate, and points per hour.
  5. Use the rate output to track logging pace and optimize operating strategy.

What each input means

Total QSOs
Total number of contacts made during the contest
Unique Multipliers
Unique multipliers worked (states, countries, zones, etc.)
Points per QSO
Point value per QSO (used for Standard contest type)
Contest Type
1=Standard (QSO×Pts), 2=ARRL (CW=2, Phone=1), 3=CQ WW (DX=3)
CW QSOs
Number of Morse code contacts
Phone QSOs
Number of voice (SSB/FM) contacts
Digital QSOs
Number of digital mode contacts (FT8, RTTY, etc.)
Bonus Points
Any bonus points (power multiplier, special stations, etc.)
Operating Hours
Total hours spent operating during the contest

How this is calculated

Formula

Score = (QSO Points × Multipliers) + Bonus

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Total QSOs = 150, Unique Multipliers = 35, Points per QSO = 2, Contest Type = 1 = 9 input(s) provided
  2. Calculate Final Score
    Final Score
    10500 = 10500
  3. Calculate QSO Rate
    QSO Rate
    12.5 = 12.5
  4. Calculate Value of +1 Multiplier
    Value of +1 Multiplier
    300 = 300
  5. Calculate Total QSO Points
    Total QSO Points
    300 = 300
  6. Calculate Points per Hour
    Points per Hour
    875 = 875
