How Car Insurance Premiums are Calculated

Understanding how your car insurance premium is determined can help you find ways to lower your costs. While every provider uses a unique proprietary algorithm, most calculations rely on a specific set of core risk factors.

Key Factors Affecting Your Rate:

  • Vehicle Value and Type: Expensive cars cost more to repair or replace. High-performance sports cars often carry higher premiums due to increased accident risks.
  • Driver Age: Statistically, drivers under 25 and over 70 are viewed as higher risk, which typically results in higher premiums.
  • No Claims Discount (NCD): This is a reward for safe driving. For every year you don't make a claim, your insurer provides a percentage discount, often up to 50% after five years.
  • Coverage Type: Third-party insurance is the legal minimum and usually the cheapest, while Comprehensive coverage protects your own vehicle but comes at a higher price.

Example Scenarios

Profile Car Value Est. Premium
New Driver, Economy Car $15,000 $900 – $1,200
Experienced Driver (5yr NCD), SUV $40,000 $800 – $1,100

Tips to Lower Your Premium

If your calculated estimate is higher than expected, consider increasing your voluntary excess (deductible), improving vehicle security with an approved alarm system, or opting for a higher NCD by avoiding small claims.
