How Long Should Your Term Life Insurance Be?
By Amara Taylor · Updated October 13, 2026 · 6 min read
How long should a term life insurance policy last? Long enough to cover the last year anyone depends on your income. In practice that is the later of three dates: when your youngest child is self-supporting, when the mortgage is paid off, and when your partner could manage on their own income and savings. Round up to the next term length insurers offer.
The timeline method
- Write down the dates that end a need. The year your youngest turns 18 or finishes college, the last mortgage payment, and the year your partner’s retirement savings would be enough without your income.
- Count the years to the latest of them. That is your minimum term.
- Round up, not down. Insurers sell set term lengths. Running out a year early leaves a gap at the age when new cover costs most.
- Check the amount for the same years. The years you pick here are also the income years in a needs sum such as the DIME method.
Three households, three answers
These profiles are invented to show the method. Bars run from today; the longest bar sets the term.
Age 32, children aged 1 and 4, mortgage with 28 years left
The mortgage outlasts the children’s dependence, so it sets the minimum at 28 years.
Term: 30 yearsAge 45, children aged 12 and 15, mortgage with 15 years left
Fifteen years covers both. A 20-year term costs more but adds a margin if the mortgage is refinanced or a child needs longer support.
Term: 15 or 20 yearsAge 55, no children at home, mortgage with 6 years left
The need here is short and shrinking. The partner’s retirement plan sets the minimum at 8 years.
Term: 10 yearsLaddering: two policies instead of one
A family’s need is usually largest now and falls as debts are paid and children grow up. Some buyers match that with two or more policies that end at different times.
The first household above might hold one policy for 20 years, covering the children’s years, and a second for 30 years, sized for the mortgage. The total cover steps down when the shorter policy ends, which can cost less than one large 30-year policy. Ask for quotes both ways before deciding.
What happens when the term ends
The cover stops and nothing is paid out. According to NAIC, most term policies can be renewed for further terms even if your health has changed, but premiums can rise with each renewal and some policies stop renewing at a certain age.
Many term policies can also be converted to a cash value policy during a conversion period, at a higher premium. If you think you may need some cover for life, check the conversion terms before you buy. To weigh term against permanent cover, use the term vs whole life calculator.
Common mistakes
- Choosing the term from the price. A shorter term is cheaper because it covers fewer years, not because it is better value.
- Ignoring a refinance. Refinancing into a new 30-year loan can push the mortgage date past the end of the term.
- Forgetting the youngest child. Use the youngest, not the oldest, and allow for college if you plan to fund it.
- Counting only work cover. Group life insurance often ends when you leave the job, so it cannot replace a term you own.
Decide the amount for the same years, using income, debts and what you already have.
