Term Life Insurance Needs Calculator
The DIME method is the standard approach recommended by the Life Insurance and Market Research Association (LIMRA) and many financial planners for estimating life insurance needs. DIME stands for Debt, Income, Mortgage, and Education. Add your total non-mortgage debts, the present value of your future income for the years your dependents need support, your outstanding mortgage balance, and estimated education costs for each child. The total is your gross coverage need. Subtract existing life insurance and liquid savings to find your net insurance gap.
DIME method formula
DIME Total = Debts + (Annual Income x Years) + Mortgage + Education
Net Gap = DIME Total - Existing Coverage - Liquid Assets
Each component addresses a specific financial obligation your family would face. The income component is a simplified present value using a straight multiplier rather than a discounted cash flow, which is the standard DIME convention.
DIME method breakdown
- Debt (D): All non-mortgage liabilities such as credit cards, auto loans, student loans, and personal loans your family would need to pay off.
- Income (I): Annual income multiplied by the number of years your dependents need financial support. This replaces lost earnings.
- Mortgage (M): The outstanding balance on your home loan so your family can keep or sell the home without that burden.
- Education (E): Estimated total cost of college or university for all dependent children.
Frequently asked questions
What is the DIME method for life insurance?
DIME stands for Debt, Income, Mortgage, and Education. You add your total debts, the present value of your future income (years remaining times annual income), your outstanding mortgage balance, and the estimated cost of your children's education. The sum is your recommended life insurance coverage amount.
How many years of income should I include?
Most financial planners suggest including the number of years until your youngest dependent is financially independent, typically age 18 to 22. If you have 15 working years left, multiply your annual income by 15 as a starting point.
Does the DIME method account for existing assets?
The basic DIME method does not subtract existing savings or other life insurance. After calculating your DIME total, subtract liquid assets such as savings accounts and existing coverage to arrive at the net insurance gap.
Should I include my spouse's income in the calculation?
You should calculate separately for each income earner. If your spouse also provides income, a separate DIME calculation for them will help determine their coverage need. Each policy covers one insured person.
What term length should I choose?
Choose a term that covers your longest financial obligation. If your youngest child is 5 and you have 20 years left on your mortgage, a 20-year term typically makes sense. Match the term to when your dependents will be financially independent.
