What DIME covers
DIME is a quick way to make sure a policy would actually replace what you provide:
- Debt — non-mortgage balances (cards, car, personal loans) so your family isn’t left with them.
- Income — your annual income times the number of years your family would need it. Replacing 10 years is a common middle ground; until the youngest child is independent is another.
- Mortgage — enough to pay off the home so housing is secure.
- Education — a fund for your children’s schooling.
Then subtract what you already have — existing policies and liquid savings. What’s left is the gap. A simpler cross-check is the “10–12× income” rule; if the two land far apart, dig into why.
A worked example (the estimator's defaults): $20,000 debt + ($80,000 income × 10 years = $800,000) + $250,000 mortgage + $100,000 education = $1,170,000 of need. Subtract $100,000 of existing coverage and savings and the gap is $1,070,000 — round to a $1M–1.1M term policy. Change any input above and watch the number move.
One nuance DIME skips: it adds up raw dollars, but a lump sum your family invests also earns returns while they spend it down. If you'd rather not overshoot, the present-value approach — the amount that, invested conservatively, replaces the income stream — often lands a bit lower than DIME's straight multiplication. DIME errs on the safe side, which for most families is the right direction to err.
Two common mistakes
Leaning only on work coverage. Group life is usually one to two times salary and disappears when you change jobs — fine as a top-up, risky as your whole plan. Buying the wrong type. For income replacement and a mortgage, term insurance is usually the cheapest fit; permanent policies earn their place for lifelong needs. See types of life insurance to match the product to the job.
What that coverage costs
Once you have a number, the natural next question is what it will cost. There’s no single price — premiums swing enormously based on a few factors you can partly control. The good news: for most people the right coverage is far cheaper than they expect.
A note on numbers: any “average premium” you see online is close to meaningless for you, because your age and health dominate. The only figure that matters is a real quote based on your profile.
Two of the price factors below connect directly to the estimate you just made. The size of the gap is your coverage amount, and the number of years you chose to replace income is a useful guide when you think about how long the coverage needs to last. Sizing the need first and pricing it second keeps you from paying for coverage you don’t need — or from trimming coverage you do need just to hit a premium.
What drives the price
- Age. The single biggest lever. Premiums rise steeply with age, so the same policy costs a healthy 30-year-old a fraction of what it costs a 50-year-old. Buying earlier locks in a lower rate.
- Health. Conditions, weight, blood pressure, and smoking status all matter — tobacco use can multiply the premium. Family history and prescriptions factor in too.
- Coverage amount. More death benefit costs more. That’s why it pays to size it with the DIME method above rather than guessing.
- Term length. A 30-year term costs more than a 10-year term because the insurer is on the hook longer.
- Policy type. The biggest split: term vs permanent. Permanent coverage (whole or indexed universal life) costs many times more than term for the same death benefit, because it lasts for life and builds cash value.
The hidden lever: your underwriting health class
Two people the same age can pay very different premiums for the same policy because the insurer sorts applicants into health classes after underwriting. Roughly, best to worst: Preferred Plus → Preferred → Standard Plus → Standard → Substandard/Table ratings, plus a separate, much higher smoker track. Moving up even one class can cut the premium meaningfully, and the class you're quoted at application isn't final until underwriting confirms it. Two practical takeaways: the "as low as" price in an ad assumes Preferred Plus (few people qualify), and it's worth addressing controllable factors — especially tobacco — before you apply.
Two stable rules of thumb also help you sanity-check a quote: for level term, the premium roughly doubles for each decade older you buy, and tobacco use can roughly double or more the rate versus a nonsmoker. Neither replaces a real quote — they just tell you whether a number is in the right ballpark.
Why term is so much cheaper
Term insurance is pure protection for a set window and pays only if you die during it — no cash value, no lifelong guarantee. That’s why, for a temporary need like covering a mortgage or replacing income while kids are dependent — exactly the needs DIME measures — term delivers the most coverage per dollar by far. Permanent insurance earns its higher price only when you have a permanent need.
Practical ways to lower your premium
- Buy younger and healthier — the rate you lock in reflects today’s age and health.
- Match the product to the need — don’t pay for permanent coverage if the need is temporary.
- Right-size the death benefit — enough to cover the gap your DIME estimate shows, not a round number.
- Improve controllable factors — quitting tobacco, in particular, can dramatically cut the rate.
- Pay annually — many insurers add a fee for monthly billing.
- Compare insurers — for the same applicant, prices vary widely between carriers; one quote is not the market.
Frequently asked questions
- How much life insurance do I need?
- A common starting point is DIME: Debt + Income × years + Mortgage + Education, minus coverage and savings you already have. The “10–12× income” rule is a quick cross-check. Both are estimates; your situation may differ.
- Does DIME overestimate?
- It can, slightly, because it adds raw dollars without crediting the investment return a lump sum would earn while it's spent down. A present-value estimate often lands a bit lower. DIME deliberately errs on the safe side.
- Does employer coverage count?
- You can subtract it, but cautiously — group life is usually limited (often one to two times salary) and ends when you leave the job, so treat it as a supplement rather than your core coverage.
- What determines the cost of life insurance?
- Mainly age and health, the coverage amount, the term length, and the policy type. Younger, healthier applicants pay less; larger death benefits and longer terms cost more; and permanent coverage costs far more than term for the same death benefit.
- Why is term so much cheaper than permanent?
- Term covers a set period with no cash value; permanent lasts for life and builds cash value, so it costs many times more for the same death benefit. For income replacement and a mortgage, term is usually the cheapest fit; permanent is for lifelong needs, and many people combine both.
- What is a health class and how much does it matter?
- After underwriting, insurers rate you Preferred Plus, Preferred, Standard, or a substandard/table rating, with a separate smoker track. The class drives a large share of your premium — moving up even one class can lower it meaningfully, and tobacco use can roughly double or more the rate.
- How can I lower my premium?
- Buy younger, choose term for temporary needs, right-size coverage, improve health factors before applying, pay annually, and compare multiple insurers.
