Insurance premiums explained

How age, health, occupation, location, insured amount, deductibles, and renewal shape the price.

Direct answers

Premiums depend on the insured amount and risk factors — age, health, occupation, location, vehicle, pet, deductible, and selected benefits — and can rise sharply on age-based renewal.

Key points

  • A published example premium is an illustration, not a quote for you.
  • A higher deductible lowers the premium but raises your out-of-pocket loss.
  • Renewable term cover reprices upward at each renewal because you are older.
  • Auto and pet premiums also reflect no-claim class, breed, and age.

Compare benefits before price

Normalize the benefits — amounts, definitions, waiting periods, and renewal — before comparing premiums. The cheapest first-year premium can become the most expensive over time if it renews steeply or pays a narrower benefit.
