Term life insurance comes in multiple lengths: 10, 15, 20, 25, 30, and 40-year options. Each has different costs and different implications for your family’s protection. Understanding how term length affects pricing, and aligning term length with your specific financial obligations, ensures you buy appropriate coverage without paying for unnecessary years or leaving gaps in protection.
Available Term Options: 10 to 40 Years
Every Term Length Serves a Different Purpose
Standard term lengths are 10, 15, 20, 25, 30, and 40 years. Some companies offer other lengths (35-year terms are less common), but these six cover most situations. Shorter terms cost less monthly but provide protection for fewer years. Longer terms cost more monthly but lock in rates for extended periods. The choice depends on your specific obligations and how long your family would need protection if you died today.
10-Year Term
Lowest cost. For temporary obligations (recent college graduates, new parents in the first 10 years only). Coverage ends when renewal rates spike significantly. Usually not recommended unless obligations genuinely end in 10 years.
15-Year Term
Moderate cost. Good for obligations ending around 15 years (youngest child in high school when term ends). Reasonable middle ground, but may expire before all children are independent.
20-Year Term
Most popular choice. Covers the main earning and child-raising years. The age 30-50 bracket finds this to be the sweet spot between cost and coverage duration. Works for most typical families.
25-Year Term
Extended protection. For those with longer obligations (youngest child born later, later career start, extended dependency). Slightly higher cost than a 20-year but provides five additional years of certainty.
30-Year Term
Maximum standard coverage. For younger purchasers (age 25-35), ensuring protection through age 55-65. Covers typical mortgage and full child-raising years. Significantly higher cost than a 20-year.
40-Year Term
Extended beyond typical needs. Rarely recommended. Only for those in excellent health starting in their 20s who want maximum length. Very expensive; a 30-year loan is usually more practical.
How Long Do You Actually Need Coverage?
Obligations Define Duration
Your need for life insurance is directly tied to your financial obligations. When those obligations end, your need for coverage typically ends. The key is identifying when your primary obligations—child support, mortgage, income replacement—actually conclude. Most people need protection for 20-30 years, though the exact duration varies significantly.
Timeline: Youngest Child’s Independence
Most families need protection until their youngest child graduates high school and becomes financially independent (approximately age 18). If your youngest is currently 3 years old, you need 15 years of coverage. If your youngest is 8, you need about 10 years. If your youngest is not yet born, you need approximately 18-22 years, depending on when you start your family. This single factor often determines appropriate term length.
Timeline: Mortgage Payoff
Your mortgage obligations typically define a lower bound on term length. A 30-year mortgage means you need at least 30 years of coverage. If your mortgage will be paid off in 15 years, you technically only need 15-year coverage for that obligation. However, this ignores other factors like income replacement. Use mortgage length as a baseline, not the only factor.
Timeline: Retirement Savings
If you’re building retirement savings, you might reasonably stop needing life insurance when you reach retirement age (typically 60-67). A 35-year-old who plans to retire at 65 might need 30 years of coverage. A 45-year-old planning to retire at 65 needs 20 years. This approach assumes you’ll accumulate sufficient retirement savings by retirement age—if you won’t, you may need longer coverage.
Realistic Approach: Most people should select a term length that extends 5-10 years beyond when they expect their primary obligations to end. This provides a safety margin. If obligations disappear earlier than expected, great—you had extra protection. If they extend slightly longer, you’re covered.

Why Longer Terms Cost Significantly More
The Math: Risk Compounds Over Time
A 20-year term covers years 1-20. A 30-year term covers years 1-30. In those additional 10 years (years 21-30), you’re significantly older and statistically more likely to have health issues. The insurance company’s risk of paying a claim increases substantially. This is why a 30-year policy costs roughly 50-75% more than a 20-year policy, not just 50% more as you might initially assume.
Example: The Cost Difference Compounds
A 30-year-old buying $500,000 coverage:
• 20-year term: $32-40/month = $7,680-9,600 total cost
• 30-year term: $44-56/month = $15,840-20,160 total cost
The 30-year term costs approximately 100-110% more than the 20-year term. You’re not just adding 50% more years; you’re adding years when mortality risk increases substantially. This illustrates why choosing the shortest appropriate term (rather than overshooting to maximum length) makes practical financial sense.
The Tradeoff: Monthly Cost vs. Coverage Certainty
If you choose a 20-year term when you actually need 25 years, you save money today but face problems 20 years from now. At that point, you’re older and have higher rates if you renew. You could be uninsurable if your health has changed. The question becomes: Is $200-300/year in savings today worth the risk of being uninsured or uninsurable in 20 years? For most people with dependents, the answer is no.
Strategy Consideration: Sometimes buying a slightly longer term (20 instead of 15, or 25 instead of 20) makes sense for peace of mind, even if it costs more. The incremental cost might be minimal compared to the security of guaranteed coverage through extended obligations.
Recommended Terms by Life Situation
Age 25-30, Single or Newly Married, No Children
Recommended: 20-25-year term. You have decades of earning ahead and likely have dependents or obligations that will exist 20+ years. Locking in low rates for 20-25 years provides protection and peace of mind. If children come later, you’ll still have substantial coverage remaining.
Age 30-40, Married with Young Children (Youngest Under 10)
Recommended: 25-30-year term. Your youngest child will be 10 years from now, 18-22 years from now. You likely have 20-30 years of mortgage remaining. A 25-30-year term ensures coverage through all major obligation years. The cost premium is worth the certainty.
Age 40-50, Married with Teenage Children (Youngest Over 10)
Recommended: 15-20 year term. Your youngest likely becomes independent within 15-20 years. Mortgage payoff might happen in 15-20 years. A 15-20 year term aligns with your actual obligations. You can always buy additional coverage if needed.
Age 50-60, Empty Nesters or Minimal Dependents
Recommended: 10-15-year term. Children are independent. Your mortgage is substantial but will be paid before you retire (in many cases). You primarily need coverage for estate purposes or to ensure your spouse isn’t burdened with final expenses. Shorter term reduces costs.
Age 60+, Approaching Retirement
Recommended: 10-year term or less (or permanent insurance). At this stage, term life insurance is less common because rates become expensive and needs are minimal. Consider permanent (whole life) insurance if coverage beyond retirement is needed, or accept that you’re moving into a stage where life insurance transitions from income protection to estate planning.
Flexibility Point: These are guidelines, not rules. Your specific obligations might vary. A 35-year-old with younger children might need 30 years. A 40-year-old planning early retirement might need only 10. Calculate your actual obligations and work backward.
Renewal and Conversion Options When Your Term Ends
What Happens When Your 20-Year Term Expires?
When your term ends, you have three options: let the policy expire (uninsured), renew for another term at new (higher) rates, or convert to permanent insurance. Most policies include automatic renewal options and conversion privileges. It’s crucial to understand these before your term ends so you don’t lose coverage unexpectedly.
Renewal at Higher Rates
Most term policies allow renewal without new medical exams (guaranteed renewable). However, the new rate is based on your age at renewal. A 20-year policy purchased at 30, renewing at 50, will have rates reflecting 50-year-old mortality risk, not 30-year-old risk. Renewal costs could be 3-5x higher than your original rate. If you still need coverage, renewal might still be worth it. If you don’t need coverage, you let it expire.
Conversion to Permanent Insurance
Many term policies include conversion rights, allowing you to convert to permanent (whole life or universal life) insurance without new medical exams. This is valuable because if your health has deteriorated, you can maintain coverage. Permanent insurance costs significantly more but provides lifetime coverage. Conversion is an option only if you want to continue coverage beyond your term.
Planning Ahead: When you buy your term policy, clarify renewal and conversion options. Don’t assume they’re automatic. Some policies have limited conversion windows or limited renewal periods. Understand these conditions now, not when your term ends.
Common Mistakes in Choosing Term Length
Mistake #1: Choosing Too Short a Term to Save Money
A 35-year-old with two young children buys a 15-year policy to minimize cost. At 50, when coverage expires, their youngest is only 18 and potentially in college. They need coverage, but now at much higher rates with health changes. The initial cost savings evaporate in renewal costs. Choose a term that lasts through your actual obligations, even if it costs more initially.
Mistake #2: Buying Too Long a Term Unnecessarily
A 45-year-old with teenagers buys a 30-year policy (until age 75) when a 15-year policy would last until their 60s, when they’re likely retired. The 30-year policy costs 50% more for coverage they don’t need. The 15-year term is more appropriate and leaves money for other financial priorities.
Mistake #3: Not Accounting for Changing Circumstances
A 30-year-old with no children buys a 20-year term, thinking they don’t have dependents. At 35, they have children and now wish they’d bought a 25 or 30-year term. Buying insurance is an opportunity to cover not just current obligations but reasonably anticipated future ones.
Mistake #4: Assuming You Can Buy More Insurance Later
At 30, you’re healthy and buy $250,000 thinking you’ll buy more at 40. At 40, you develop high blood pressure. New applications are declined or offered at much higher rates. You can’t increase the original policy without new underwriting (unless guaranteed increase options exist). Buy appropriate coverage now while healthy and rates are low.
Frequently Asked Questions About Term Length
Is a 20-year term the best length for everyone?
Direct answer: No. 20 years is the most popular, but the optimal length varies individually.
A 20-year term is the most common choice because it covers typical mortgage and child-raising years for many people. However, a 25-year-old with a newborn might need 30 years. A 50-year-old with teenage children might need only 10. Calculate your actual obligations, then choose accordingly.
Can I change my term length after I buy the policy?
Direct answer: No. Term length is locked when you purchase.
You can’t change a 20-year policy to a 30-year mid-term. When your term ends, you can renew for a new term or convert to permanent insurance, but you can’t modify the existing policy’s length. This is why choosing the right term length initially matters so much.
What’s the longest term I can buy?
Direct answer: 40 years, though availability decreases at longer lengths.
Most companies offer up to 40-year terms. Some have maximum ages for certain lengths (e.g., 40-year-olds only available to age 55). Anything beyond 40 years becomes permanent insurance (whole life). For most people, 30 years is the longest needed; 40 years is rarely optimal.
If my obligations end in 20 years, should I buy a 25-year policy?
Direct answer: It depends on the cost difference and your risk tolerance.
If obligations truly end in exactly 20 years, a 20-year term is appropriate. However, “exactly 20 years” rarely happens. Kids graduate at varying ages. Mortgages might extend longer. If the cost difference between 20 and 25 years is minimal ($10-15/month), a 25-year term provides 5 additional years of peace of mind. If the difference is substantial ($50+/month), stick with 20.
Do I pay less if I buy a longer term now instead of renewing later?
Direct answer: Yes, significantly. Buying long-term now is much cheaper than renewing at older ages.
A 35-year-old buying a 30-year policy costs less than a 35-year-old buying a 10-year policy and then renewing at 45. Renewal rates at 45 will be much higher than initial rates locked at 35. This is why buying an appropriate term length initially, rather than shorter and planning to renew, usually makes financial sense.
Can I buy multiple policies with different term lengths?
Direct answer: Yes, and this is a valid strategy for some people.
A person might buy a 20-year policy for $500,000 and a separate 10-year policy for $250,000. When the 10-year expires, they reassess. This strategy provides flexibility but adds complexity. Most people benefit from a single policy matching their total obligations and timeline, rather than juggling multiple policies.
