Introduction
“How much coverage do I need?” is the question that stops more people from buying life insurance than price ever does — not because the math is hard, but because most people have never actually done it. The default move is picking a round number that feels big ($250,000, $500,000) and hoping it’s close enough. It usually isn’t. Here are three real methods, from quickest to most precise, so you can land on a number you’re actually confident in.
Quick answer: Most financial guidance points to somewhere between 10 and 15 times your annual income as a starting benchmark, but the most accurate number comes from adding up your specific debts, income replacement years, and future obligations — not from a generic multiplier alone.
Method 1: The Income Multiplier (Fastest, Least Precise)
Take your annual income and multiply it by 10-15. It’s a rough starting point, useful if you want a ballpark figure in ten seconds, but it ignores your actual debts, number of dependents, and existing savings — so treat it as a floor, not a final answer.
Method 2: The DIME Method (More Precise)
We covered this in detail in our guide on [common life insurance buying mistakes], but as a refresher, DIME adds up four categories:
- Debt — total non-mortgage debt (credit cards, loans)
- Income — years of income replacement needed × annual income
- Mortgage — remaining balance on your home
- Education — future education costs for your children
This method tends to produce a more realistic (and usually larger) number than the income multiplier alone, because it accounts for your actual financial obligations instead of a flat ratio.
Method 3: The Full Needs-Based Worksheet (Most Precise)
This is the version financial planners actually use. Fill in your own numbers below — it takes about five minutes if you have your debt and savings figures handy.

| Step | What to enter | Your number |
|---|---|---|
| 1. Final expenses | Funeral/burial costs (avg. $8,000-$12,000) | $______ |
| 2. Outstanding debt | Credit cards, personal loans, car loans | $______ |
| 3. Mortgage balance | Remaining balance on your home | $______ |
| 4. Income replacement | Annual income × years you want to cover | $______ |
| 5. Future education costs | Estimated per child × number of children | $______ |
| 6. Subtotal (add lines 1-5) | $______ | |
| 7. Existing coverage | Employer policy + any current personal policy | −$______ |
| 8. Existing savings/investments | Liquid assets that could offset the need | −$______ |
| 9. Your coverage target (line 6 minus lines 7-8) | $______ |
The subtraction step (lines 7-8) is the part most people skip, and it matters — if you already have $200,000 in savings or a $100,000 employer policy, your gap is smaller than your subtotal suggests, and you may be able to buy less coverage than the raw DIME or multiplier number implies.
A Note on “Rounding Up”
Life insurance is priced in bands, and the cost difference between, say, $475,000 and $500,000 of coverage is often small relative to the total premium. If your worksheet number lands close to a round figure, it’s usually worth rounding up slightly rather than buying an oddly specific amount — the extra cushion rarely costs much more per month.
When to Recalculate
Your number isn’t permanent. Recalculate after a major life change: a new mortgage, a new child, a significant income change, or paying off a large debt. Many policies allow you to layer an additional policy rather than replacing the original, so recalculating doesn’t necessarily mean starting over.
Frequently Asked Questions
Is it bad to buy more coverage than I calculate I need? Not necessarily — a modest buffer is reasonable, especially since premiums are cheapest while you’re young and healthy. The bigger risk is usually under-insuring, not over-insuring.
Should I include my spouse’s income in the calculation? Only if your household genuinely depends on both incomes to cover expenses. If one income alone could sustain the household, the calculation may not need to fully replace the other.
Does this worksheet work the same way for a stay-at-home parent? The income replacement line changes — instead of replacing a salary, estimate the cost of replacing the unpaid work they do (childcare, household management), which is often underestimated and can run higher than expected.
