Term life vs whole life

Purpose, premium, renewal, cash value, and cost over time for each design.

Direct answers

Term costs less for a temporary income need and usually has no cash value; whole life costs more but continues for life and may build surrender value — most households use large term for dependent years plus a small permanent policy only if a lifelong need exists.

Key points

  • Term: low premium, fixed period, little cash value, age-based renewal.
  • Whole life: higher premium, lifelong, possible surrender value.
  • The cheapest first-year premium can be the costliest over time.
  • Large term + small permanent is a common efficient structure.

Compare cost over the whole horizon

Do not compare only the first-year premium. Model the total cost over the period you actually need cover, including renewal repricing for term and the guaranteed surrender value for whole life, and match each to a temporary or permanent need.
