Start lesson 1 How insurance works and makes money

Key takeaways

  • An insurer is paid first and pays later. It collects premiums today, pays claims when bad things happen, and invests the money in between.
  • An insurer's profit is premiums minus claims minus expenses, plus investment income.
  • Insurance is local. Rules, products, and distribution differ by country, so ask early which country, which line, and which channel the case is about.
By the end you will be able to
  • Explain the three main lines of insurance and who buys them
  • Calculate the loss ratio, expense ratio, and combined ratio, and add investment income
  • Explain reinsurance and work out what an insurer keeps after a large loss
  • Describe the main distribution channels and the takaful model
  • Crack typical insurance cases, starting with the right ratio
