2. How much life insurance do you need? Calculating needs - Part1 Larry and Ginny Stewart are 52 years old and have one daughter, age 14. Larry is the primary earner, making $80,000 per year. Ginny does not currently work. The Stewarts have decided to use the needs analysis method to calculate the value of a life insurance policy that would provide for Ginny and their daughter in the event of Larry's death. Larry and Ginny estimate that while their daughter is still living at home, monthly living expenses for Ginny and their child will be about $3,300 (in current dollars). After their daughter leaves for college in 4 years, Ginny will need a monthly income of $2,750 until she retires at age 65 . The Stewarts estimate Ginny's living expenses after 65 will only be $2,300 a month. The life expectancy of a woman Ginny's age is 87 years, so the Stewart family calculates that Ginny will spend about 22 years in retirement.
