Life insurance is a letter you write to people who will open it on the worst day.
The letter says: I cannot be there, but the rent will be paid; the school will be funded; the grief will not be compounded by invoices.
It is tender math.

The core decision is term versus permanent.
Term is pure insurance: coverage for a defined period, low premiums, no cash value.
For most families, sufficient term coverage—often 10–20 times annual income during the years of dependence—is the efficient answer.
Permanent policies (whole, universal, variable) combine insurance with a savings component.
They can be appropriate for specific needs—lifelong dependents, estate planning—but are frequently oversold.
Calculate needs pragmatically: debts to eliminate, years of income to replace, future obligations like college, final expenses.
Subtract existing assets and other coverage.
Buy from strong carriers, ladder policies to match declining needs (e.g., 10-year and 20-year terms), and favor level premiums.
Avoid riders you do not understand; some add value (disability waiver), others pad commissions.

Underwriting will ask about health, lifestyle, and sometimes financials.
Be truthful.
Shop across carriers; risks are priced differently.
If you are uninsurable or rates are prohibitive, consider employer group coverage while you can and build assets aggressively.
Do not delay because the topic is uncomfortable.
