Direct answer
Buy the term length that matches the period you need financial protection for; if you expect major obligations to end within a decade, a 10‑year term is sufficient, otherwise a 20‑year term provides broader coverage.

Key factors to compare
- Duration of financial responsibilities (mortgage, childcare, education)
- Affordability of premiums over time
- Age and health at purchase
- Future income expectations and potential policy conversion options
Cost implications
Premiums for a 20‑year term are typically 20‑30% higher than a comparable 10‑year term because the insurer assumes risk for a longer period. The price gap narrows as you get older; younger buyers see the biggest savings with shorter terms.
Flexibility and conversion
Many carriers allow you to convert a term policy to permanent coverage without medical underwriting. A 20‑year policy gives you more time to evaluate conversion before the term ends, while a 10‑year policy may require an earlier decision.
