Is $250,000 enough? Should it be ten times your salary? Those are the two questions most Chicago parents bring when they start asking how much life insurance a family needs, and neither one has a universal answer. A rule of thumb ignores the things that make your household yours: a two-flat in Avondale with a 30-year loan, a car payment, two kids in grade school, a spouse who works part time. The better approach is a short worksheet that adds up what your family would actually have to pay for, then subtracts what would already be there. Planners often call it the DIME method, for debt, income, mortgage and education. Below, it is broken into six steps, with the Cook County and Illinois details that national calculators leave out.
Key Takeaways
- The right amount of life insurance is the gap between what your family would need to pay for after your death and the resources they would already have.
- The DIME method adds four needs: non-mortgage debt, years of lost income, the mortgage balance and education costs.
- Paying off a Chicago-area mortgage does not end housing costs, because Cook County property tax bills keep arriving in two installments every year.
- Social Security survivor benefits can cover part of the income gap for children under 18, but they are not a substitute for coverage.
- Group life through an employer usually ends when the job does, so count it carefully.
- The term length should match your longest need, usually the year your youngest child becomes independent.
Step 1: Add up the debts that would outlive you
The first line of the worksheet is every debt other than the mortgage that your family would have to keep paying. That means car loans, credit card balances, personal loans, private student loans you co-signed and any money borrowed against a retirement account. Write down the current balance, not the monthly payment.
Add a line for final expenses as well. The Illinois version of the NAIC Life Insurance Buyer’s Guide, which the state adopted in its administrative code, asks buyers directly how their family would pay final expenses and debts. Funeral and burial bills tend to arrive within weeks, long before an estate is settled, so they belong on this line rather than in a later step.
Not every debt belongs on the list. A loan that is in your name alone and is not secured by anything your family keeps may be handled differently than a joint balance or a co-signed loan, so read the terms of each one and list it at its full balance if you are unsure.
Step 2: Put a number on the income your family would lose
Income replacement is usually the largest line and the one with the most judgment in it. Start with your take-home pay, not your gross salary, because your family would not be paying your payroll taxes or your 401(k) contributions. Then decide how many years that income needs to last.
For most parents, the answer is the number of years until the youngest child is on their own. A household whose youngest is four might plan for eighteen years; one whose youngest is fifteen might plan for seven or eight. If a surviving spouse earns a solid income, some families replace only part of the lost paycheck. If a spouse would need to cut back work to handle childcare, they may need more than your full salary for the first few years.
Social Security can fill part of this gap. According to HealthCare.gov’s definition of Social Security survivors benefits, benefits can go to unmarried children under 18 (or under 19 and still in school) and to a widow or widower of any age who is caring for a child under 16. Those payments stop as the children age out, and the one-time lump sum is only $255, so treat Social Security as a partial offset to the income line, never the whole answer.
Step 3: Decide what happens to the mortgage and the tax bill
The mortgage line is simple to fill in: use the remaining principal balance on your loan, not the original amount. Many families want enough coverage to pay the house off entirely so a surviving spouse is never forced to sell, especially if the kids are settled in a school they love.
What the simple version misses in Cook County is that a paid-off house still has bills attached. The Illinois Department of Revenue explains that Cook County bills property taxes in two installments, with the first installment set at 55 percent of the prior year’s bill and the second covering the balance. Those bills keep coming after the mortgage is gone, and so do upkeep costs and, for condo owners, association dues. If your monthly escrow payment is a meaningful share of your housing cost, add several years of property taxes to the mortgage line or fold them into the income line in Step 2.
If you rent, skip the payoff and instead include rent in the income you are replacing.
Step 4: Price out school with Illinois numbers in mind
The education line is the most personal. Some parents want to cover four years at a state university, some want to cover community college and a transfer, and some leave college out entirely and focus coverage on the years at home. There is no wrong answer, but there should be a deliberate one.
Write down a target per child and then subtract what you have already saved. Illinois families often save through the state’s 529 plans; the Illinois State Treasurer notes that Bright Start contributions are deductible on Illinois income taxes, up to $10,000 for individual filers and $20,000 for joint filers. Whatever is already in those accounts reduces the amount the policy needs to provide.
Step 5: Subtract what is already in place
Once the four needs are added up, subtract the resources your family would already have. The Illinois buyer’s guide lists the life insurance you have now, Social Security, pension survivor benefits and savings and investments as things to count against the total.
Be careful with two of them. Group life insurance through an employer is often set as a multiple of salary, and it usually ends when you leave the job, so a family that relies on it can lose a big piece of protection after a layoff. Retirement accounts can be tapped by a surviving spouse, but drawing them down to pay the mortgage today means less to live on later. Many households count only part of those balances for that reason.
Step 6: Match the term length to the longest need
The amount is only half the decision; the other half is how long the coverage needs to last. Look back at the worksheet and find the need that runs the longest. It is usually the income line, which ends when the youngest child is independent, or the mortgage, which ends at payoff. A term life policy of 20 or 30 years is often chosen to cover that window, because premiums stay level for the whole term.
Some families split the total across two policies with different lengths so coverage drops as the mortgage shrinks and the kids grow up. Others buy one policy and review it every few years.
A worked example, step by step
The table below is a hypothetical household, not a client, built only to show how the arithmetic works. Assume two parents in Chicago, children aged three and six, one parent earning $70,000 in take-home pay.
| Worksheet line | How it is figured | Amount |
|---|---|---|
| Debts and final expenses | Car loan, credit cards, funeral estimate | $45,000 |
| Income | $70,000 x 15 years until the youngest is 18 | $1,050,000 |
| Mortgage and taxes | Remaining loan balance plus five years of property tax | $340,000 |
| Education | Target per child minus current 529 savings | $120,000 |
| Minus existing coverage | Group life at work, one times salary | -$70,000 |
| Minus savings | Half of liquid savings | -$15,000 |
| Coverage gap | Total needs minus resources | $1,470,000 |
The total looks large, and that is normal. Income replacement over many years is a big number for almost any family with young children, which is exactly why term coverage exists.
What to do if the total feels too big
If your number comes out higher than you expected, do not round it down to whatever feels comfortable. Go back through the worksheet and test the assumptions instead: could a working spouse carry part of the income line, could the education target be lower, could two policies with different lengths cover the early years more heavily than the later ones? Each of those is a real decision that changes the price, while simply buying less coverage leaves a hole you cannot see.
It also helps to run the worksheet again after big moments: a new baby, a move from a city condo to a house in Oak Park or Park Ridge, a raise, or a paid-off loan. If you already own a policy and are not sure it still fits, a policy review is a good place to start, and Life Insurance Chicago Illinois can walk through the numbers with you when you want a second set of eyes.
