How Much Insurance Coverage Do I Need?
Coverage amounts should come from adding up obligations, not from a multiple of income. Here is what belongs in the calculation and what does not.

Why rules of thumb fail
"Ten times your income" is popular because it is easy to say. It ignores whether you have a mortgage, whether your children are two or twenty-two, and whether an employer already provides coverage.
Two households with identical incomes can have coverage needs that differ by several hundred thousand dollars. The only way to know which one you are is to add up the actual obligations.
What belongs in the calculation
Four categories cover most situations. Income replacement keeps the household running for a defined number of years. Debt payoff removes obligations that would otherwise transfer to survivors. Education costs are usually the largest single future commitment for families with children. Final expenses cover the immediate costs that arrive within weeks.
Subtract what already exists: employer group cover, individual policies already in force, and liquid savings that would genuinely be available rather than earmarked for something else.
- Income replacement - annual income × years of support needed.
- Mortgage balance and other debts.
- Expected education costs for dependants.
- Final expenses and estate settlement costs.
- Less: existing coverage and accessible savings.
Liability coverage is a separate question
Life cover protects the people who depend on your income. Liability cover protects your assets and future earnings from a claim made against you, and it is sized completely differently - against net worth plus the income a judgment could reach.
Default liability limits on home and auto policies are usually set to satisfy a state minimum, not to protect what you own. Umbrella policies exist precisely because the underlying limits are often far below the exposure.
The number changes over time
Coverage need peaks when debt is highest and dependants are youngest, then falls steadily. A mortgage amortises, children become independent, and savings accumulate.
This is the practical argument for matching a term to the period of highest need rather than buying permanent cover sized for a moment that passes. Re-running the calculation after any major change almost always shows the honest number has moved.
What to do with the result
Treat it as a starting figure to take into a conversation, not a final answer. Coverage decisions interact with tax treatment, estate structure and local law - all of which sit outside any calculator.
What the calculation does give you is a documented basis for the amount, which is far more defensible than a multiple someone quoted at you.
Frequently asked questions
How many years of income should I replace?
A common approach is the number of years until the youngest dependant is financially independent, or until a surviving partner reaches retirement age. There is no universally correct figure.
Should employer coverage count?
Count it, but note that most group cover ends when employment does. If it is a large share of your protection, that dependency is worth recognising.
Is more coverage always better?
No. Coverage costs money every year. Buying substantially more than the obligations justify diverts money from other goals without protecting anyone further.
How often should I review the amount?
After any major change - a new mortgage, a birth, a job change, a debt paid off - and otherwise every two or three years.
