Calculate how much life insurance coverage you need based on income, debts, and dependents. Get a personalized recommendation to protect your family.
The DIME formula — Debt, Income, Mortgage, Education — is the standard method for calculating life insurance needs. This calculator walks through each component to determine the coverage amount that would protect your family's financial future if something happened to you.
This life insurance needs calculator uses the income replacement method to determine how much life insurance coverage you need to financially protect your dependents. The methodology calculates the total coverage needed by multiplying your annual income by the number of years your family would need support, then adds outstanding debts (mortgage, car loans, student loans, credit cards), adds future obligations like college education costs for each child, and subtracts any existing coverage you already have. The underlying premise is that if you died, your family would need enough to replace your income stream and cover known expenses without depleting assets. Real-world use cases include purchasing new life insurance, evaluating whether existing coverage is adequate after major life events (marriage, baby, home purchase), and adjusting coverage as income changes over time. Key limitations include not accounting for Social Security survivor benefits (which can provide a base level of income), life insurance through employer group plans, existing savings and investments outside retirement accounts, or inflation over the coverage period. This calculator provides a starting point based on a commonly taught formula; comprehensive insurance needs analysis should account for your complete financial picture and goals.
Result: For a 35-year-old earning $75,000/year with 10 years of income replacement needed: income replacement equals $750,000. Adding $150,000 in debts, $160,000 for two children's college funds ($80,000 each), minus $100,000 existing coverage gives a total recommended coverage of approximately $960,000. This provides a financial buffer for the family to adjust to life without the primary earner's income.
