The One Rule That Cuts Through It
Insure against what you cannot afford to absorb; self-insure the rest. A catastrophic event - a disability that ends your income, a house fire, an early death with dependents relying on you - can erase a lifetime of saving. Those are the risks worth paying to transfer.
Small, survivable costs are not. Extended warranties, phone insurance, and low-deductible add-ons mostly transfer risk you could comfortably cover yourself - at a price that reliably favours the insurer. When the loss is one you could pay for out of your emergency fund, skip the policy.
Health Insurance
The single most important cover, because medical costs are both unpredictable and potentially unlimited. How you obtain it varies enormously by country - through a public system, an employer, or an individual policy - but the principle holds everywhere: an uninsured serious illness is one of the fastest routes to financial ruin.
Where you choose a plan, balance the premium against the deductible. A high-deductible plan with lower premiums can be the better deal if you are healthy and hold a solid emergency fund to cover the gap; a lower-deductible plan makes sense if you expect regular care.
Disability Insurance: The Most Overlooked
Your ability to earn is almost certainly your largest asset - larger than your home or your portfolio. Yet disability insurance, which replaces a portion of your income if illness or injury stops you working, is the cover people most often lack.
You are statistically more likely to face a period of disability during your working years than to die during them. If anyone depends on your income - including just yourself - long-term disability cover deserves a serious look, and it is cheapest when you are young and healthy.
Life Insurance: Only When Someone Depends on You
Life insurance exists to replace your income for the people who rely on it. If no one depends on you financially, you likely don't need it. Once you have a partner who shares expenses, children, or a mortgage on a shared home, it becomes essential.
- Term life covers a fixed period (say, until the kids are grown or the mortgage is paid) at low cost. For most families, this is the right answer.
- Whole / permanent life bundles insurance with an investment component. It is far more expensive and rarely the best home for investment money - keep insurance and investing separate unless you have a specific estate-planning reason.
A common sizing guideline is roughly 10 times your annual income, adjusted for existing savings and debts your family would need to clear.
Property and Liability
If you rent, renters insurance is one of the best-value policies in existence - it covers your belongings and, crucially, personal liability, usually for a small monthly cost. If you own, home insurance is typically mandatory with a mortgage and protects your largest physical asset.
Auto insurance is legally required in most places; carry enough liability cover that an accident you cause can't bankrupt you. Across all property policies, choose the highest deductible your emergency fund can comfortably absorb - it lowers your premium and keeps you from filing small claims that raise your rates.
How Coverage Changes Over a Lifetime
Insurance needs are not static - they track your obligations:
- Starting out: Health, renters, disability. Life insurance usually unnecessary.
- Partnering and home-buying: Add life insurance and home cover; increase disability as income grows.
- Raising a family: Peak coverage. Term life and disability matter most here, when dependents rely on you.
- Approaching retirement: Needs shrink as savings grow and dependents become independent - term life can often lapse. Long-term care cover enters the picture.
Because needs shift with each life stage, review your policies whenever a major life event happens - not on a fixed schedule. The wrong amount of insurance is as much a planning error as the wrong investments.
