I'm afraid we can't calculate that - but here's some info you may find helpful. The fines and the penalties depend on the seriousness of the offence. Although, you can only do a speed awareness course every 3 years - so each of those 4 offences will be penalty points. The court will decide how long the disqualification will last, based on how serious they think the offence is. It's down to their discretion, but instant bans tend to be issued if you have been caught exceeding the speed limit significantly - say - by 45%. In most cases, an instant driving ban can last between seven and 56 days – depending on the nature of the speeding offence. For more serious speeding offences (over 100mph or 30mph over the limit, for example), an instant ban can last up to 120 days. Penalty points will typically range between 3 and 6, but the court may decide to issue an immediate ban with no penalty points.

If you’ve been caught speeding at an allegedly high speed, and already have 6 or more points on your licence, it is very likely the court will impose 6 more points, which would take your total to 12 or more. This will result in a totting up ban of 6 months. You can be banned from driving if you already have 12 or more penalty points on your licence. Your ban can last 6 months if you get 12 or more penalty points within 3 years, 12 months if you get a second disqualification within 3 years or 2 years if you get a third disqualification within 3 years.

If you’re disqualified for 56 days or more you must apply for a new licence before driving again. You might also have to retake your driving test or take an extended driving test before getting your full licence. The court will tell you if you have to do this. Lastly, this is a bit obvious, but I'd recommend sticking to the speed limits in future.
