How much life insurance do I actually need?

The short answer

Add up what you owe, what your household would need to replace your income for the years it matters, and any future costs you want covered, then subtract savings and existing coverage. For most Long Island families that lands somewhere between ten and fifteen times household income, though the honest number depends on your mortgage balance and how many years your dependents still need support.

Start with the four numbers that matter

Every reasonable method for sizing life insurance is doing the same four things in a different order. You can skip the acronyms and just answer these directly.

Debts. Mortgage balance, home equity line, car loans, student loans, credit cards, and anything you personally guaranteed for a business.
Income replacement. Your annual contribution to the household, multiplied by the number of years it would need to be replaced.
Future obligations. College, a special needs family member, care for an aging parent, a funeral.
Existing resources. Savings, retirement accounts you would actually be willing to spend down, and any coverage already in force.

Coverage need equals the first three added together, minus the fourth. That is the entire calculation. Everything else is refinement.

How many years of income should you replace?

This is where the number moves the most, and where people guess instead of thinking. The right answer depends on who is depending on you and for how long.

Young children at home: replace income until the youngest is finished with school, which is often eighteen to twenty two years.
Teenagers: five to ten years is often enough to get them launched and let a surviving spouse restabilize.
A spouse who would need to retrain or return to work: at least three to five years, more if their earning capacity is far below yours.
No dependents, but shared debt: enough to clear the debt, and not much more.

The common shortcut of ten times income is a reasonable starting point for a working parent, but it is a starting point. A thirty two year old with a newborn and a five hundred thousand dollar mortgage needs more than ten times. A fifty eight year old with grown kids and a nearly paid off house probably needs less.

Do not forget the non earning spouse

A parent who stays home is doing work that would otherwise be paid for. Childcare, transportation, meals, and the coordination that keeps a household running all have market prices, and a surviving spouse who has to keep working will be paying them.

The practical test is simple: if that person were not here next month, what would you have to hire, and what would it cost annually? Multiply by the years the children are still at home. On Long Island that number is regularly well over half a million dollars, and the coverage to address it is inexpensive because the insured is usually young and healthy.

Why Long Island numbers run high

National calculators assume national costs, and the gap here is not small.

Home values in Nassau and Suffolk sit far above national medians, so mortgage balances are larger and last longer.
Property taxes here rank among the highest in the country, and they are a fixed cost that does not shrink when a household loses an income.
Childcare, commuting, and everyday costs all run above national averages.

The result is that a family here typically needs meaningfully more coverage than the same family would in most of the country, while paying essentially the same rate per thousand dollars of benefit. Coverage is priced on your age and health, not your zip code.

What about coverage you already have?

Subtract it, but subtract it carefully.

Group life through your employer usually ends when the job does, and typically runs one to two times salary. Count it, but do not build on it.
Union or fund death benefits are often a flat amount and are tied to your standing. Find out the actual dollar figure before you subtract anything.
Old policies may be nearing the end of their term. Check the expiration date and the conversion deadline, which usually comes first.
Retirement savings count only to the extent your family would really spend them down, which for most people is less than the balance suggests.

Two examples

A young family in Suffolk County

Two parents, ages 34 and 36, one earning ninety thousand and one earning sixty thousand, two children under five, four hundred and forty thousand left on the mortgage, thirty thousand in savings, and a group policy worth one times salary on each.

Debts of four hundred and forty thousand, plus roughly eighteen years of replacing the larger income, plus a college goal, minus savings and group coverage, puts the higher earner somewhere near one and a half million dollars of need and the lower earner near nine hundred thousand. A thirty year term on each, bought while both are in their thirties, is far more affordable than those figures suggest.

A Nassau County couple in their late fifties

Children grown, one hundred and ten thousand left on the mortgage, solid retirement savings, and no dependents. The need has collapsed to clearing the remaining loan, covering final expenses, and leaving a spouse comfortable. That is a much smaller policy, and permanent coverage starts to make more sense than another thirty year term.

A rule worth remembering

Buy the amount your family would actually need, at a premium you will still be paying in ten years. A policy you cancel in year three protects nobody.

If the right number is not affordable as permanent coverage, buy it as term. A large term policy beats a small permanent one for a household that would be in trouble without the income. You can convert some of it later, when there is more room in the budget.
