Term life insurance is the simplest and cheapest way to protect the people who depend on your paycheck. Unlike whole life, which bundles insurance with an expensive investment account, term life pays out a fixed death benefit if you die during a chosen window — typically 10, 20, or 30 years — and costs a fraction of a permanent policy. The hard question is not whether to buy it, but how much. This calculator estimates the death benefit your family would need to replace your income, clear your debts, and fund your children's education, then turns that number into a rough monthly premium based on your age.
Adjust the sliders and every figure updates instantly. Because rates rise quickly with age, running this number in your thirties or forties can lock in a rate you will not see again.
How to Use
- Enter your Annual Income — your gross household pay before taxes. This is the money your family would lose if you were gone tomorrow.
- Set your Current Age. This drives the premium band; a 30-year-old pays roughly a third of what a 50-year-old pays for the same death benefit.
- Choose your Planned Retirement Age. The difference between that and your current age is the number of years your family still relies on your paycheck.
- Add Total Debts — mortgage balance, car loans, student loans, and credit cards you want paid off in a lump sum.
- Add Future College Costs if you are raising children. A single in-state degree can run $100,000 or more; two children doubles it.
- Subtract your Current Savings & Investments — cash, 401(k), and brokerage accounts that would already help your family survive.
- Pick a Term Length. Twenty years is the sweet spot for most young families; thirty years matches a long mortgage; ten years works if your kids are nearly grown.
The result card shows your years of income to replace, the total financial need, the recommended death benefit, the coverage as a multiple of your salary, and an estimated monthly premium.
The Income-Replacement Formula
Most planners use a variation of the DIME rule — Debt, Income, Mortgage, Education. This calculator condenses it into one transparent equation:
Recommended Coverage = (Annual Income × Years Until Retirement) + Total Debts + Future College Costs − Current Savings
Worked example on the default numbers: a 35-year-old earning $80,000, planning to retire at 67, with $250,000 of debts, $150,000 of projected college costs, and $60,000 saved. Years to replace = 32, so income replacement is $80,000 × 32 = $2,560,000. Add debts and college: $2,560,000 + $250,000 + $150,000 = $2,960,000. Subtract savings: $2,960,000 − $60,000 = $2,900,000 recommended. That is about 36 times annual income — higher than the old "ten times salary" rule of thumb, because the old rule ignored mortgage, college, and how long you actually have left to work.
If your planned retirement age equals your current age, years to replace is zero; the calculator still covers your debts and remaining education costs, which is the right result for someone already on the verge of stopping work.
How Premiums Are Estimated
Term premiums are priced almost entirely by age, health class, and face amount, bundled into age bands. The rates below reflect a healthy non-smoker buying a level term policy, averaged across male and female rates:
- Under 30: about $0.05 per $1,000 of coverage per month.
- 30–39: about $0.06 per $1,000.
- 40–49: about $0.11 per $1,000.
- 50–59: about $0.25 per $1,000.
- 60 and over: about $0.45 per $1,000.
So the default $2,900,000 policy at age 35 works out to 2,900 × $0.06 = $174 per month. A 50-year-old buying the same $2,900,000 would pay roughly $725 — more than four times as much. Smoking, obesity, diabetes, or a dangerous hobby can push you into a higher band; excellent health can nudge the rate down.
Examples
Example 1 — The default young family. A 35-year-old teacher earning $80,000, with $250,000 mortgage debt, one child and a planned $150,000 college fund, and $60,000 in savings. The calculator recommends a $2,900,000 20-year policy at about $174/month. That is roughly the price of a single streaming subscription plus a phone bill for a level of protection that would pay off the house, put the child through school, and replace 32 years of salary.
Example 2 — High earner with a big mortgage. A 45-year-old engineer earning $200,000, planning to retire at 65, carrying a $1,200,000 mortgage, $200,000 of projected college costs, and $300,000 saved. Years to replace = 20; total need = $4,000,000 + $1,200,000 + $200,000 = $5,400,000; recommended coverage = $5,100,000. At the 45-year-old band of $0.11 per $1,000, the monthly premium is about $561.
Example 3 — Near retirement. A 67-year-old still working, planning to retire this year, with $200,000 of remaining debt and no college ahead. Years to replace = 0, so the calculator recommends $150,000 of coverage (debts minus savings) at the 60+ band — roughly $68/month. At this stage a small 10-year policy covers the mortgage without overinsuring.
FAQ
How much term life insurance do I actually need?
A common rule of thumb is 10 to 12 times your annual income, but that shortcut ignores your mortgage, children's college costs, and savings. This calculator uses the fuller income-replacement formula: income times years until retirement, plus debts and college, minus what you have already saved. For most households in their thirties and forties, that lands between $1,000,000 and $3,000,000.
Is term life insurance worth it?
For the vast majority of families, yes. A healthy 35-year-old can buy a $1,000,000 20-year policy for $40–$60 per month. Whole life costs 10–15 times more for the same death benefit because it bundles a savings account with historically modest returns. Buy term and invest the difference if you want the investment piece.
What is the difference between term and whole life?
Term life covers you for a fixed number of years (10, 20, or 30) and pays out only if you die during that window. Whole life covers you for your entire life and builds a cash value, but premiums are much higher and fees eat into returns. Choose term if you need protection during your working years; choose whole life only for estate-tax or permanent-trust needs.
How long should my term be?
Pick a term that lasts until your youngest child is financially independent, your mortgage is paid off, and your savings have grown enough to replace your income. For most couples buying in their thirties, a 20- or 30-year term matches the length of a mortgage and the cost of raising a family.
Does term life insurance increase in price as I age?
Your premium is locked for the level term period — a 20-year policy costs the same each month for 20 years. But if you let it expire and buy a new policy at age 55, the new rate is based on your older age and possibly poorer health. That is the main reason to buy the longest term you can afford while you are young.
Can I buy term life insurance if I have health issues?
Yes, but you may be rated into a higher premium band or asked for a medical exam. Conditions like diabetes, high blood pressure, or a history of smoking can raise the price. Some carriers offer no-exam policies with slightly higher rates and lower face amounts, typically capped at $500,000 or less.
What happens at the end of the term?
You can let the policy expire, convert part of it to a permanent policy without a new medical exam (many 20- and 30-year policies include a conversion option), or renew annually at a much higher rate. Most people let it lapse once the mortgage is paid and the kids are grown.
