Insurance Coverage Calculator

Rules of thumb like "ten times your income" are popular because they are easy, not because they are accurate. They ignore whether you have a mortgage, whether your children are two or twenty, and whether you already hold coverage through an employer.

This calculator adds up the actual obligations that money would need to cover, subtracts the resources already in place, and reports the difference. The output is a needs analysis, not a sales figure.

Result

Additional coverage needed

$1,498,000

Total need: $1,688,000
Income replacement portion: $1,275,000
Debt payoff portion: $278,000
Education portion: $120,000
Final expenses portion: $15,000
Existing coverage and savings: $190,000
Share of need already covered: 11.26%
Surplus over the stated need: $0

This is an estimate based on the values you entered. Actual premiums, coverage, eligibility and pricing vary by provider and by individual circumstances.

This method adds up obligations rather than applying a rule of thumb multiple of income. It ignores inflation and any investment return on the payout - the present-value tool handles those.

Coverage needs change with every major life event. Re-run this whenever income, debts or dependants change.

How to use the insurance coverage calculator

Enter the annual income that would need replacing and the number of years it should last.
Add the mortgage balance, other debts, expected education costs and final expenses.
Enter any existing coverage and liquid savings that would be available.
Read the coverage gap - the amount of additional protection the numbers support.

What people use this for

Deciding how much life cover to buy before requesting quotes.
Checking whether employer-provided group coverage is enough on its own.
Re-running the numbers after a mortgage is paid down or a child finishes school.
Documenting the reasoning behind a coverage amount for your own records.

Worked examples

Every figure below is produced by running this calculator against the example inputs, so the numbers always match the tool.

Household with young children

$85,000 of income to replace for 15 years, a $260,000 mortgage, $18,000 of other debt, $120,000 of expected education costs, $15,000 of final expenses, against $150,000 of group coverage and $40,000 of savings.

Additional coverage needed: $1,498,000
Total need: $1,688,000
Share of need already covered: 11.26%

Mortgage nearly paid, children independent

The same income but only 5 years of support needed, a $40,000 remaining mortgage, no education costs and $300,000 of existing coverage.

Additional coverage needed: $95,000
Surplus over the stated need: $0

What belongs in a coverage calculation

Four categories cover most households. Income replacement keeps the household running. Debt payoff removes obligations that would otherwise fall on survivors. Education costs are usually the largest single future commitment for families with children. Final expenses cover the immediate costs that arrive within weeks.

What does not belong is a target lifestyle upgrade. Insurance is there to prevent a financial shock, not to fund something the household was never going to afford.

Why the gap shrinks over time

A coverage need is highest in the years when debt is largest and dependants are youngest. As the mortgage amortises and children become independent, the same household needs materially less coverage. This is the main argument for term insurance that matches the period of highest need rather than permanent coverage sized for a moment that passes.

Re-running this calculation every few years, or after any major change, usually reveals that the honest number has moved.

Methodology and assumptions

What this calculator does, and what it deliberately does not do.

Total need = (annual income × years) + mortgage + other debts + education + final expenses.
The gap subtracts existing coverage and liquid savings from that total. Inflation and investment return on a payout are not modelled here - the income replacement tool handles that separately.
All figures are estimates produced from the values you enter. This site has no rate feed and no carrier data, so it cannot quote or price a policy.

No result produced here is an offer of insurance or a guarantee of coverage. Only a licensed insurer or agent, working from your verified details, can quote or bind a policy.

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. There is no single correct answer - it depends on who relies on the income and for how long.

Should I count employer group life cover?

Count it, but be aware most group cover ends when employment ends. If it is a large share of your protection, that dependency is worth noting.

Does this calculator account for inflation?

No. It adds up needs in today’s money. To account for inflation and the return a lump sum could earn, use a present-value income replacement calculation instead.

Is a coverage gap always a problem?

Not necessarily. It means the obligations you listed exceed the resources you listed. Whether that matters depends on who would be affected and what other support exists.
