How it works

A risk is a chance of a costly surprise, like a river flooding a cellar.

Many families pay a small share into a pot, so a few who have a big bill are helped. That is insurance.

The small yearly payment is a premium. Asking the pot to pay is a claim.

Coins nobody needs stay in the pot for a wetter year. A calm year is the plan working.

Flooded cellars00.511.522.532Year 11Year 23Year 3cellars
Flooded cellars on Marsh Lane. Each one is a 10-coin bill.
Before the plan• 2 of 20 houses pay 10 coins each• 18 houses pay nothing• Only luck decidesWith the pot• All 20 families pay 1 coin• The pot pays the bills• Nobody pays alone
Before the plan and with the pot.

Example 1: The pot in year one

  1. 20 families each put in 1 coin: 20 × 1 = 20 coins.
  2. Two cellars flood at 10 coins each: 2 × 10 = 20 coins.
  3. The pot pays both bills and is empty.

Example 2: The pot in year two

  1. Another 20 coins go in.
  2. One cellar floods, so the bill is 10 coins.
  3. 20 − 10 = 10 coins stay in the pot.

Example 3: The pot in year three

  1. 10 coins are left over and 20 new coins go in: 10 + 20 = 30 coins.
  2. Three cellars flood at 10 coins each: 3 × 10 = 30 coins.
  3. The pot holds exactly enough.

Example 4: The fair share

  1. One year's bills were 20 coins, shared by 20 families.
  2. 20 ÷ 20 = 1 coin each.
  3. That fair share is the premium.

Try at homeAsk a grown-up about one big surprise cost that people share, like a storm or a broken car. Who helps to pay for it?
For grown-upsReal insurers keep extra coins for a very wet year and charge a little more to cover their own work, and real rules differ by place. Talk about one big surprise cost that many people share, like a storm, and who helps to pay for it.
