The four parts of the need
Income replacement is the years of pay the household would lose, chosen by you rather than assumed: ten years is a common answer for a family with young children, five for a household close to financial independence, and none is a legitimate answer when a pension or a second income already covers the spending.
The debts are what has to be cleared so the family keeps the house and the car. Education is a figure you set per child, which may be the cost of a state degree or simply a fund you mean to leave behind. Final expenses cover the funeral and the work of administering an estate.
