A customer cancels a twelve-month policy after four months. How much do you refund?

5 min readUpdated 2026-08-15

Answer

Short answer

It depends on who cancelled and why: pro rata returns the unused share, short rate keeps a penalty, and which applies is set by the policy wording and the jurisdiction rather than by the system.

Keep policy administration explicit in the answer because that is the concept the interviewer is actually trying to test. A good policy administration explanation names the trade-off, the failure mode, and the evidence you would use before choosing. Use policy administration once more at the decision point so the answer reads as judgement rather than a detached example.

Likely follow-ups

  • The insurer cancels for non-payment rather than the customer. Does the basis change?
  • A claim was paid in month two. Does that change what you return?
  • How would you reproduce this calculation for a complaint raised in three years?
  • Where does the tax on the returned premium go?
