How It Works

Speeding fines in England and Wales are calculated using a banding system based on how far over the speed limit you were driving. Band A (1-10 mph over in a 30 zone equivalent) starts at 25-75% of weekly income. Band B (11-20 mph over) is 75-125% of weekly income. Band C (21+ mph over) is 125-175% of weekly income with possible disqualification.

The minimum fine is £100 with 3 penalty points. In some cases of minor speeding, you may be offered a speed awareness course (typically £100, no points) instead of prosecution. Penalty points range from 3-6, and accumulating 12 points within 3 years results in a minimum 6-month driving ban.

Fines are capped at £1,000 (or £2,500 on a motorway). Aggravating factors such as poor road conditions, driving near schools or previous convictions can push the fine towards the top of the band. This calculator estimates the likely fine and points based on the speed recorded, the speed limit and your circumstances.

Example: 42 mph in a 30 mph zone, Band B

  1. Speed over limit: 12 mph (Band B)
  2. Starting point: 100% of weekly income
  3. Weekly income: £600
  4. Base fine: £600
  5. Penalty points: 4-6
  6. Speed awareness course alternative (if offered): £100, no points
