IRR is the discount rate at which the value of a stream of payments and receipts is exactly zero. For an insurance policy, the payments are the premiums and the receipts are the maturity or death benefit; the IRR is the policy's return as a yearly rate, comparable with a deposit's.
When the flows have irregular dates, the same calculation is called XIRR.
