How could our car insurance calculator help you save money? 

You can use our comparison tool to answer questions on things that could affect the overall price of your car insurance premium, and see how you can make adjustments to make savings:

  • The type of car you drive – if you're buying a new car, you can use the calculator to find out how the insurance premiums might change from one model you’re considering to the next. The value of the car, engine size and even desirability are all taken into account when calculating your premium.
  • Your car's security – you could save on your insurance premium if you improve your car's security. Using the calculator, you'll be asked about any security features, and will be able to compare cost against the potential savings if you have an industry-approved alarm or immobiliser fitted. You can then decide if making these improvements is worth it.
  • The level of cover – third party cover isn't necessarily always the cheapest, as the price depends on individual circumstances. Use the calculator to check the differences between third party cover, third party fire and theft, and fully comprehensive car insurance to see how they affect the price of your premium.
  • Your voluntary excess – you can use the calculator to adjust your voluntary excessthe amount you choose to pay towards a claim. If you choose a higher excess, it will likely reduce your premium, so the calculator can help you work out which level of excess suits you the most. Just remember, if there’s a claim, you'll have to pay a compulsory excess as well as your chosen voluntary excess, so make sure you can afford both.

How is car insurance calculated?

Car insurance is tailored to you, your car and where you live. Risk is the key factor for insurance providers when it comes to working out how much your premium will cost. They’ll look at a wide range of factors including:

  • Your age - car insurance for young drivers is by far the most expensive because insuring them involves more risk: it’s estimated by the Department for Transport that 10%-20% of new drivers have a crash within the first six months of passing their test. More accidents result in more claims, so insurance providers have to offset this cost by raising premiums for young drivers. On the other hand, if you’re over 50, the assumption is that you have more driving experience, so your premiums are likely to be lower if your driving history bears that out.
  • Your car - the type of car you drive is also a deciding factor when calculating the cost of car insurance. Generally, more expensive and powerful cars will cost more to insure, with repairs often more expensive. Any modifications you make to your car, like alloy wheels or a new stereo system, can raise the cost of your premium too.
  • Where you live - the risks that insurance providers look at include the possibility of your car being stolen or damaged, so they’ll consider where you live and where you keep your car overnight. They’ll look at the local crime rate, whether the area is urban or rural, and the road accident statistics for that area. Keeping your car parked overnight on a private driveway, or in a locked garage, reduces the risk of it being stolen or vandalised, and may help to cut the cost of your premium.
  • Insurance Premium Tax - there’s one other element that gets added onto the cost of your insurance and that’s insurance premium tax (IPT). It’s currently charged at 12%.

You may also want to consider a black box policy, also known as telematics. This is more popular with younger drivers, who usually face more expensive car insurance, but can potentially lower the cost by proving they are a safe driver.

The cost of your car insurance is calculated by insurance providers assessing the level of risk you pose to them. For example, if you’re young and have minimal driving experience, you’ll typically find that your car insurance costs more than for someone who has been driving for decades. You’ll also find that those who have a clean driving record, with no previous accidents and a lengthy no claims bonus, will normally get cheaper car insurance.

Car insurance providers are no longer allowed to factor gender into their quotes. Since the European Court of Justice’s gender ruling in December 2012, men and women are legally required to be treated equally when calculating the cost of car insurance.

Things which can affect the cost of your car insurance include:

  • Your age
  • The car’s value
  • The type of car
  • Your no claims bonus
  • Any previous driving convictions
  • Your annual mileage
  • Where you keep the car
  • What you use the car for
  • Your job

How can I cut the cost of my car insurance?

  • Reduce your annual mileage - statistically, the more you drive, the more likely you are to have an accident. Limiting your annual mileage could reduce your risk and that could help lower your premium
  • Drive well - a whole year of claim-free driving will earn you a no claims discount which could help reduce the cost of your car insurance. Each year you’re driving without making a claim, the greater the potential discount could be. Getting points on your licence – for speeding, for example – can result in your premium going up.
