Understanding the Life Insurance Calculator
This calculator estimates how much life insurance coverage a household may need using the DIME method, a widely used rule of thumb. DIME stands for Debt, Income, Mortgage, and Education. The goal is to size a policy that could repay debts, replace lost income for dependents, clear the mortgage, and fund children's education if the insured person dies. It is aimed at anyone with financial dependents who wants a realistic starting figure before talking to an insurer or advisor. Results are educational estimates, not a recommendation to buy a specific policy.
How it works
You enter four inputs that map to DIME: total outstanding debts (excluding mortgage), your annual income multiplied by the number of years your family would need support, the remaining mortgage balance, and projected education costs for your children. The tool sums these and can subtract existing coverage and liquid savings to show the additional coverage gap. Read the result as a target sum assured, typically met with term life insurance, which is inexpensive relative to permanent policies. The income component is the largest driver, so the years-of-support assumption strongly affects the total.
Worked example
A parent earns $60,000 a year and wants 10 years of income replacement, giving $600,000. Add $20,000 in credit-card and car debt, a $250,000 remaining mortgage, and $120,000 for two children's college costs. The DIME total is $990,000. Subtracting $50,000 in existing group coverage leaves a recommended gap of about $940,000, a figure typically covered by an affordable 20-year term policy.
Tips & common mistakes
- DIME is a starting estimate; it ignores future raises, inflation, and your spouse's own income, so refine it for your situation.
- Choose the income years deliberately: cover until the youngest child is independent, or until a surviving spouse reaches retirement.
- Term life is usually the cheapest way to hit a large coverage target; permanent insurance costs far more per dollar of cover.
- Subtract existing employer and personal policies so you do not over-insure and overpay on premiums.
- Revisit coverage after major life events such as a new child, home purchase, or paying off the mortgage.

Frequently Asked Questions
What is the DIME method?
DIME adds up four needs your life insurance should cover: Debt, Income replacement, Mortgage, and Education. It then subtracts your existing savings and insurance to find the gap.
Which methods does this calculator compare?
It runs four side by side: DIME (debt + income + mortgage + education), simple income replacement (income x years), Human Life Value (the present value of your future income to retirement, discounted), and the rule-of-thumb 10x annual income. A bar chart and table show all four so you can sanity-check the suggested figure.
What is Human Life Value?
Human Life Value estimates the present value of all the income you would earn between now and retirement, discounted to today's money. Enter your current age, retirement age, and a discount rate and the calculator does the math.
How many years of income should I replace?
A common guideline is until your youngest child is independent or your partner reaches retirement — often 10 to 20 years. Adjust based on your family's situation.
Is this financial advice?
No. It is a general estimate to help you start the conversation. Each method makes different assumptions, so the figures differ on purpose. A licensed insurance advisor can tailor coverage to your needs.
