- Existing savings and any employer-sponsored life insurance reduce the total amount you need to buy.

Why a Worksheet Beats a Guess
Most people pick a term life coverage amount the same way they pick a Wi-Fi password — quickly, without much thought, hoping it works out. That's how you end up either over-insured and paying premiums you can't afford, or under-insured and leaving your family short when it matters most.
The good news: sizing a term life policy doesn't require a financial planner or a spreadsheet degree. It does require about 30 minutes of honest number-crunching. This worksheet walks you through exactly that — income replacement, outstanding debts, your mortgage, dependent care, future education costs, and the assets you already have working for you.
Think of it like packing for a trip. If you just throw things in a bag, you'll either forget something critical or drag around a suitcase that's too heavy. A checklist keeps you efficient and confident. The same principle applies here.
If you want a deeper dive into the underlying calculation methods before you begin, this coverage sizing guide walks through the expert approaches in detail. And if you're building a broader financial picture, the full planning roadmap covers every dimension from income replacement to dependent care.

What You'll Need Before You Start
Gather these documents and figures before you begin — having them on hand will cut your working time in half and make your estimates much more accurate.
Recent pay stubs or tax return (Form 1040)
Used to confirm your gross annual income for the income replacement calculation.
Latest mortgage statement
Provides your current outstanding principal balance for the mortgage payoff section.
Debt account statements
Lists current balances on auto loans, student loans, credit cards, and other liabilities.
Current savings and investment account balances
These assets reduce the total coverage you need to purchase.
Existing life insurance policy documents
Used to subtract current coverage from your worksheet total to avoid over-insuring.
Calculator or simple spreadsheet
Makes it easy to add, subtract, and total the figures across all six worksheet groups.
College cost estimator tool
Helps project future tuition costs adjusted for inflation when completing the education section.
Childcare cost database (Care.com or local provider quotes)
Provides a realistic annual cost figure for dependent care if you are a stay-at-home parent or caregiver.
Don't Rely Solely on Employer Life Insurance
Many people assume their workplace group life policy — often 1x or 2x salary — is enough coverage. It rarely is. More importantly, that coverage disappears the moment you change jobs or get laid off. Treat employer coverage as a supplement, not your primary plan.
Estimated Figures Are Fine — Missing Categories Are Not
You don't need exact balances to the penny, but skipping entire categories — like childcare costs or education funding — will leave a real gap in your coverage. Even rough estimates beat a zero in any category.
Don't get paralyzed looking for exact figures. Round numbers are fine for this exercise. The goal is an informed range, not a figure precise to the dollar.
The Term Life Coverage Worksheet
Work through each group in order. Each section adds to or subtracts from your total coverage target. At the end, you'll combine all the figures into a single recommended coverage amount.
Not every section will apply to everyone — skip any group that genuinely doesn't fit your situation, but be honest with yourself before you skip. Underestimating today creates real gaps tomorrow.
Group 1: Income Replacement
Group 2: Outstanding Debts
Group 3: Mortgage Payoff
Group 4: Dependent and Childcare Costs
Group 5: Education and Future Milestones
Group 6: Final Expenses and Adjustments
Your Coverage Number Will Feel Large — That's Normal
Most families following this worksheet land on a coverage target between $500,000 and $1.5 million. That range is not a mistake. It reflects the real financial weight your income carries for the people who depend on you. The reassuring part: term life premiums for these amounts are far lower than most people expect — often just $30–$60 per month for a healthy person in their 30s.
Beneficiary Designations Override Your Will
This is one of the most misunderstood facts in personal finance. No matter what your will says, the death benefit from your life insurance goes to whoever is named as beneficiary on the policy. An outdated beneficiary — an ex-spouse, a deceased parent — can redirect your policy proceeds away from the people you intend to protect. Review and update beneficiary designations whenever your life changes.
Once you've worked through all six groups, your formula looks like this:
Coverage Target = (Income Replacement + Debts + Mortgage + Education + Final Expenses) − (Savings + Existing Life Insurance)
If that number feels surprisingly large, remember: term life insurance is significantly cheaper than most people expect. A healthy 35-year-old can often get $500,000 in coverage for less than the cost of a streaming subscription bundle per month.

Two Quick Calculation Methods to Cross-Check Your Number
Once you have your worksheet total, it's worth running two quick sanity checks against established calculation methods. If your worksheet number and one of these benchmarks are close, you can feel confident in your figure. If they're far apart, dig into the group where the gap likely lives.
The Income Multiplier Method
Multiply your gross annual income by 10 to 12. A household earning $70,000 per year would target $700,000 to $840,000 in coverage. This method is fast but doesn't account for debt, mortgage payoff, or existing savings — use it as a floor, not a ceiling.
The DIME Method
DIME stands for Debt, Income, Mortgage, and Education. Add those four figures together for a coverage target. It's more precise than a straight multiplier and aligns closely with the worksheet groups above. For a step-by-step walkthrough of DIME, see the full DIME method guide.

After the Worksheet: What to Do With Your Number
You've got a figure. Now what?
Step 1: Choose a term length
Match the policy term to your longest financial obligation. If you have a 15-year-old child and a mortgage with 20 years left, a 20-year term covers both. Common options are 10, 15, 20, and 30 years.
Step 2: Get quotes based on your health profile
Term life premiums are heavily influenced by age, gender, tobacco use, and health history. Apply soon — every year you wait, premiums go up. A quote from two or three insurers gives you a competitive range.
Step 3: Name your beneficiaries carefully
This is where many people get sloppy. Name a primary beneficiary and at least one contingent (backup) beneficiary. Review these names whenever you have a major life event — marriage, divorce, a new child.
Step 4: Schedule a check-in
Set a calendar reminder to revisit this worksheet in two to three years, or immediately after any major financial change: a new baby, a home purchase, a significant raise, or a paid-off debt. Your coverage needs evolve — your policy should keep pace.
For a complete audit that includes assets, liabilities, and dependent obligations in one place, the full audit checklist is a useful companion resource. And if this is your first time thinking through how much life insurance your family genuinely needs, this family needs guide is a solid next read.
Term life isn't glamorous. It's also not complicated once you've done the math. A policy sized correctly to your household is one of the highest-leverage financial moves a budget-conscious family can make — and this worksheet gives you the foundation to do it right.
