Do I need life insurance if I'm single with no kids?

The whole purpose of life insurance is to replace income or pay obligations for people who depend on you. If nobody depends on your income, the default answer is straightforward: you do not need a life insurance policy right now. But there are three specific situations where buying a small, cheap policy in your 20s or 30s is one of the smartest financial moves you will ever make.

Reason 1: Lock in your insurability now

Life insurance gets dramatically more expensive — and harder to qualify for — as you age and as your health changes. A 25-year-old in good health can lock in 30 years of $500,000 term coverage for around $20 per month. That same person at 45 with a new diabetes diagnosis or sleep apnea may pay 5 to 10 times that amount, or be denied entirely.

If there is a reasonable chance you will have a spouse or children in the next decade, buying a long-duration term policy now is the cheapest way to guarantee they will be protected later. You are not buying death benefit for today. You are buying the right to keep being insured at today's price.

Reason 2: You have private student loan or business debt with a cosigner

Federal student loans are discharged on death. Most private student loans are not — and if a parent cosigned, the balance becomes their responsibility. The same is true for business loans, car loans, or any debt where someone else signed alongside you. Enough life insurance to cover those debts protects the cosigner from inheriting a bill.

Reason 3: You support a parent, sibling, or partner financially

If you regularly send money to a parent, support a younger sibling through school, or are the primary income for a long-term unmarried partner, you have dependents — even if no court would recognize them as such. A modest policy with that person named as beneficiary fills the gap that would open up if your income disappeared.

What to buy

For all three scenarios, term life is almost always the right answer. Skip whole life, universal life, and indexed policies — those are designed for people with specific estate-planning needs, not for buying low-cost protection. A 20- or 30-year level-premium term policy with a death benefit between $250,000 and $500,000 is a typical sweet spot in your 20s and 30s.

Whatever you buy, save the policy in one place and tell one person it exists. The whole point of the policy is to reach the right hands when you cannot tell them yourself.
