UK insurance calculators

How insurance calculators work

Our calculators use published data from the Association of British Insurers (ABI) and Defaqto ratings to produce cost estimates. They aren't quotes. No insurer will hold you to these numbers. But they give you a realistic starting point before you start comparing actual policies.

The average UK household spends around £23 per month on pet insurance and £509 per year on car insurance for a petrol vehicle. EV owners pay roughly £558 per year on average. These figures shift depending on dozens of variables, and that's exactly what our calculators help you explore.

What affects pet insurance cost

Four things drive your pet insurance premium more than anything else: breed, age, location, and cover type.

Breed matters because some dogs and cats have known hereditary conditions. A French Bulldog costs around £45 per month to insure because flat-faced breeds suffer from breathing problems (BOAS), spinal issues, and eye conditions that generate expensive vet bills. A Labrador sits closer to £25 per month. Mixed breeds tend to be cheaper because they're less prone to inherited conditions; a moggy cat averages just £12 per month.

Age is the second biggest factor. Premiums typically double between age 3 and age 10 for most breeds. A healthy 2-year-old Cocker Spaniel might cost £18 per month, but by age 9 that same dog costs £38 per month or more. Insurers know older pets claim more frequently. The data backs this up: pets over 8 account for 62% of claims by value, according to ABI figures from 2025.

Your postcode affects pricing because vet costs vary by region. London and the South East are the most expensive areas, with premiums running 15-20% higher than the national average. Scotland and the North East tend to be the cheapest regions for pet insurance.

Cover type makes a big difference too. Lifetime cover (which resets your benefit limit each year) costs roughly 40% more than accident-only cover. But lifetime policies pay out far more over a pet's life. Accident-only cover starts from around £5 per month, while lifetime cover for a medium-risk breed typically runs £20-35 per month.

What affects car insurance cost

Car insurance pricing in the UK revolves around five core factors: your vehicle's insurance group, your age, where you live, your no-claims bonus, and annual mileage.

Insurance groups run from 1 to 50. A group 1 car like a Citroen C1 might cost £400 per year to insure for a 35-year-old with 5 years no-claims. A group 40 car like a BMW M3 could cost £1,200+ for the same driver. The group number reflects repair costs, performance, and theft rates.

Age hits young drivers hardest. A 17-year-old pays an average of £1,800 per year. By age 25 that drops to around £700. And by 40, with a full no-claims bonus, you're looking at £350-500 depending on the car. The cost curve flattens significantly after age 30.

Location matters because some postcodes have higher theft and accident rates. Inner-city Manchester and parts of East London consistently rank among the most expensive areas. Rural postcodes in Devon or the Scottish Highlands are often 30-40% cheaper.

Your no-claims discount is the single most valuable thing on your policy. Nine years of no-claims can reduce your premium by 60-70%. Losing it after a fault claim can double or triple your renewal quote overnight. Protecting your no-claims bonus adds around £30-60 per year to most policies, but it's often worth the money.

EV vs petrol: the insurance gap

Electric vehicles cost 10-15% more to insure than their petrol equivalents in 2026. This gap has closed significantly from 25% in 2024. The reasons EVs cost more come down to repair economics: battery packs cost between £5,000 and £15,000 to replace, fewer garages are certified to work on high-voltage systems, and parts take longer to source.

But this is changing fast. More independent garages are getting EV certification every month. Battery repair techniques (rather than full replacement) are becoming standard. And insurers have 3 more years of claims data to work with compared to 2023, which means they can price risk more accurately rather than adding a blanket loading.

Our data sources

We pull data from the ABI's published market statistics, Defaqto's product ratings database, and individual insurer pricing pages. Our pet insurance figures are based on averages across 15 major UK pet insurers. Car insurance data comes from ABI quarterly reports and the FCA's general insurance market study.

We update our calculator models quarterly. The figures you see reflect Q2 2026 market data. They won't match any specific insurer's quote exactly, because every insurer weighs factors differently. But they'll put you within 10-15% of what you'll actually be quoted in most cases.

Guides and further reading

Our blog covers the questions people ask most about insurance. You'll find guides on how pet insurance works, which breeds are cheapest to insure, how age affects premiums, and the current state of EV insurance. Each guide uses real numbers and specific examples rather than vague generalities.
