Why is your average claim the wrong number?

Thirty settled files, five cost bands, and one number that decides the year. Half the claims close under ten thousand dollars, and a single file is worth more than the twenty cheapest put together.

What Do Claims Actually Cost?

  1. In your spreadsheet, click the Sortia icon in the strip of icons down the right-hand edge. No strip? Click the arrow at the bottom-right to open it. You can also use Extensions, then Sortia, then Open Sortia.
  2. Click Start from a template and put that name in the search box.
  3. Pick the card with that name and click Load this template. It arrives on a new tab with real numbers already in it.

The answer

Where the files land, and where the money goes:

Under $10,000
50% of the files
Under $80,000
96.7% of the files
The one in "More"
23.4% of everything paid out
The twenty cheapest
25.1% of everything paid out

The arithmetic that matters is not the average claim of $20,247 and it is not the median of $10,200. It is that one file in thirty decides roughly a quarter of the annual cost, so a reserve set from the average is wrong in both directions at once: too high for the ordinary file and far too low for the one that matters. Move the top band down to $40,000 and four claims land in "More", which is a useful reminder that where you put the last band is a decision about what you are calling a large loss, and it should match the definition your reinsurance already uses.

The model

One row per settled claim with the amount and each claim as a share of the year, plus five band limits. The Histogram tool counts the bands and returns the cumulative column beside them.

Once it is in your sheet

  1. The model arrives with real numbers in it and runs as it stands, so you can press the button first and understand it second.
  2. Change the numbers to yours. The sheet marks which cells are inputs and which hold formulas, and most labels carry a note explaining the row.
  3. Press the run button at the bottom of the panel. It is labeled for the tool you are in, and the result lands on its own tab, with a written reading of it beside the figures.
