What is Proportional Insurance?

Pro Rata is a Latin term meaning "in proportion." In the context of insurance, a prorated premium is the amount an insurance company charges for a policy that covers less than the full term.

This calculation is commonly used in situations such as:

  • A new policy begins in the middle of the billing cycle
  • An existing policy is canceled before its renewal date
  • Coverage is increased or decreased during the policy term

By using a prorated calculation, insurers ensure that policyholders only pay for the coverage they actually receive. It's a fair and cost-effective way to adjust premiums, benefiting both insurance companies and their customers.

Common Scenarios

Mid-Term Policy Start

If you start a new auto insurance policy 3 months into the year, you'll only pay for 9 months of coverage instead of the full year.

Example: $1,200 annual premium for 275 days = $904.11

Early Cancellation

When canceling a homeowners policy after 7 months, you may receive a refund for the unused 5 months of premium.

Example: $900 annual premium used for 210 days = $517.81 (refund $382.19)
