When should I buy life insurance?
By Colson · Updated June 13, 2026
The best time to buy life insurance is when someone becomes financially dependent on you — or right now, if that's already true — because rates only rise with age and health changes. Buying younger and healthier locks in a lower premium for the entire term.

Getting married, buying a home with a mortgage, having a child, or becoming the primary earner for anyone are the classic triggers. If someone would struggle financially without your income — or you've taken on debt others would inherit — it's time to consider coverage.
Why buying younger saves money
Term life premiums are based largely on age and health, and they only go up. A policy bought at 30 locks in a 30-year-old's rate for the whole term; waiting until 40 or until a health issue appears can multiply the cost — or make coverage harder to get. If you'll need it, sooner is almost always cheaper.
How much and what type?
For most people, level term life sized with the DIME method (debts, income, mortgage, education) covers the dependent years affordably. Buy enough to replace your financial role, and choose a term that lasts until your dependents are independent or the mortgage is paid.
Frequently asked questions
What is the best age to buy life insurance?
Generally as soon as someone depends on your income — often your 20s or 30s. Rates rise with age and health changes, so buying younger locks in a lower premium for the full term.
Do I need life insurance if I'm single with no kids?
Often not, unless you have co-signed debt, support a parent or sibling, or want to lock in a low rate before future dependents. Otherwise you can usually wait until a life event creates the need.
Should I buy life insurance through work or on my own?
Employer group coverage is a good baseline but is usually limited and ends when you leave. An individual term policy is portable and can be sized to your actual needs — many people carry both.
