Speeding Fine Calculator

If you have received a notice of intended prosecution for a speeding related offence, then you may be wondering about the penalty that you could face if found guilty in court. Whilst there is no guarantee as to the exact sentence that you will receive, it is often possible to predict a speeding penalty with a certain level of accuracy. This is because the courts use a set of sentencing guidelines when issuing penalties and fines for speeding offences. Using these guidelines, as well as details of the offence you have been accused of, we can predict the most likely penalty that you could face.

Use the speeding fine calculator below to find out the penalty that your speeding offence could result in.

Speeding Fines: Aggravating & Mitigating Factors

As mentioned above, there are a number of factors that could influence the exact penalty that you receive, and no two cases are likely to be exactly the same. If any ‘aggravating factors’ apply to your case, then you could receive a more serious penalty than the one indicated by the above tool. Some of the most common aggravating factors for speeding offences include:

  • The weather conditions were poor
  • The road surface was in a poor state of maintenance or repair
  • You were carrying passengers in the vehicle
  • You were carrying a heavy load
  • You were driving a LGV, HGV, PSV, etc.
  • There was a lot of traffic on the road
  • There was a lot of pedestrian traffic nearby.

All of the above factors would increase the level of danger presented by driving over the speed limit, and so ‘aggravate’ or increase the severity of the offence, and therefore the penalty, too. There are also mitigating factors that could apply to your case – such as the presence of a genuine emergency – which could serve to lessen the sentence that you receive.


Maximum Speeding Fines

As you may have noticed in the speeding ban calculator above, fines for speeding offences are typically represented in terms of a ‘band’, rather than an actual monetary value. This is because different people could receive different fines, depending on their income. The table below illustrates the typical starting point for each fine band, as well as the minimum and maximum range that each band could stretch to.

Starting PointPotential Range
Band A Fine50% of relevant weekly income25 – 75% of relevant weekly income
Band B Fine150% of relevant weekly income75 – 125% of relevant weekly income
Band C Fine150% of relevant weekly income125 – 175% of relevant weekly income

As an example, if you were issued with a Band A fine, then this would automatically equate 50% of your weekly income. If mitigating factors are present, then the fine could be reduced to as little as 25% of your weekly income, and if aggravating factors are present, then you could face paying up to 75% of your weekly income.

Fixed speeding penalties

It could be the case that you receive a fixed penalty as a result of committing a speeding offence, which will not fluctuate depending on the amount that you earn. If this applies to your case, then the following amounts apply:

Level 1£200
Level 2£500
Level 3£1000
Level 4£2,500
Level 5£5,000

Remember that the penalty you receive may comprise of more than just a monetary fine – you may also receive points on your license and a potential ban from driving. It is also worth noting that you may be offered the opportunity to take a speed awareness course in order to reduce the severity of your penalty, though this is never a guarantee.
