How to Use

  1. Enter your current premium and the renewal quote.
  2. Add broker fees (percent or flat) if applicable.

  4. Calculate, then copy the summary to support negotiation and internal decision-making.

What Results Mean

Premium delta shows the renewal change in premium.

Expected out-of-pocket is a simple estimate: claims per year times average out-of-pocket per claim.

Total cost of risk (TCR) is premium plus broker fees plus expected out-of-pocket.

Common Pitfalls

  • Comparing premiums without normalizing coverage limits and exclusions.
  • Assuming claims frequency and severity without referencing actual loss runs.
  • Ignoring the operational cost of switching carriers or brokers.
