How to use this calculator
The DIME method adds up Debt (mortgage + other debts), Income replacement (annual income × years), and Education fund. Existing savings and coverage are subtracted to arrive at additional coverage needed.
- 1
Enter your annual income and the number of years your family would need income replaced if you passed away.
- 2
Add your mortgage balance, other debts, and any education fund you want to leave for your children.
- 3
Enter your existing savings and current life insurance coverage — the calculator subtracts these to show your additional coverage gap.
Frequently asked questions
What method does this tool use?
A DIME-style tally. Debt is the mortgage balance plus other debts, Income is annual income × the years you enter, and Education is the single fund amount you type in. Those three are added, then existing savings and existing life cover are subtracted. The mortgage balance is therefore folded into the debt line rather than shown as its own total.
What is the exact calculation with the default inputs?
Debt = 200,000 + 25,000 = 225,000. Income = 60,000 × 10 = 600,000. Education = 50,000. The total need is 875,000. Subtracting 30,000 of savings and 0 of existing cover leaves 845,000, which the tool labels the recommended additional coverage.
Why can the result be zero?
The additional coverage is floored at zero. If savings plus existing cover exceed the total need, the tool shows $0. With the defaults and 900,000 of existing cover, the subtraction is 930,000 against an 875,000 need, so the result is $0 and the premium estimate is also $0.00.
Where does the monthly premium estimate come from?
It is the additional coverage multiplied by 0.0004, a flat rate built into the tool (equal to $0.40 per $1,000 of cover each month). It does not consider age, health, tobacco use, policy length or insurer, so treat it as a placeholder. A licensed agent’s or insurer’s own quote is the figure that applies.
Are savings treated as fully available to the family?
Yes. Whatever you enter as existing savings and investments is subtracted in full, with no allowance for taxes, market changes or the fact that the funds may be needed for other things. The tool also does not tell income apart from the capital left behind.
What is not in the calculation?
Inflation, investment returns on a payout, taxes, final expenses, a surviving partner’s earnings, childcare costs, and ongoing needs beyond the years you enter. It is a snapshot of four buckets, so the years-of-income figure is the main assumption you control.
Should I treat the number as the amount to buy?
No. It is a tally of the inputs you provided, shown in dollars with no currency logic. The tool does not recommend a cover amount or policy type, and a licensed adviser can help interpret your situation. Unusual circumstances, such as a dependent with lifelong needs, are not captured.
Life insurance needs calculator: a DIME-style tally with savings and existing cover subtracted
What gets added and what gets subtracted
The calculator adds three buckets: debts (mortgage balance and other debts together), income replacement (annual income multiplied by the years you want covered) and a lump sum for education. It then subtracts existing savings and existing life insurance. If what remains is negative the result is shown as zero. The final line applies a flat 0.0004 monthly rate to that net figure, which is a built-in placeholder rather than a quote.
The default case, line by line
The table breaks the default inputs into the same lines the tool displays, so you can see how each input flows into the result.
| Line | How it is formed | Amount |
|---|---|---|
| Debt coverage | 200,000 mortgage + 25,000 other debts | $225,000 |
| Income replacement | 60,000 income × 10 years | $600,000 |
| Education fund | Entered directly | $50,000 |
| Total need | Sum of the three lines | $875,000 |
| Less savings and cover | 30,000 savings + 0 existing cover | $30,000 |
| Additional coverage | Total need − subtractions | $845,000 |
More worked runs
Beyond the default, which shows a rough monthly premium of $338.00, a household with 90,000 income over 15 years, a 300,000 mortgage, 10,000 of other debts, an 80,000 education fund, 50,000 of savings and 250,000 of existing cover has a total need of 1,740,000. Subtracting 300,000 leaves 1,440,000 of additional coverage and a placeholder premium of $576.00. When existing cover is raised to 900,000 in the default scenario, the subtraction is 930,000, which exceeds the 875,000 need, so the tool shows $0 and a $0.00 premium.
Why the years input matters most
Of the four inputs, the number of years of income is the one that scales fastest, because it multiplies annual income. In the default scenario every extra year adds 60,000 to the need. The tool uses no growth rate or discount, so a year far in the future is counted at the same value as the next one. Education and debt amounts are taken as given.
What the tally cannot say
The method is a rule of thumb: nothing in it knows your tax position, the age of your children, your partner’s earnings, or what a life policy would cost for your health and age. The tool does not suggest a policy type or amount. Use the result to organize your own inputs, and take the numbers to a licensed adviser or insurer for a real quote.
