What does the insurance inertia cost from age 30 to 65?
The Insurance Inertia
$400 a year, age 30 to 65 — the long-term cost is $59,000.
How the number's built.
Auto-renewal is convenient and frictionless. It avoids the dry task of comparing policy quotes. But overpaying by $400 a year from age 30 to 65 adds up to $14,000 in out-of-pocket premiums — and $59,000 in compounding redirected by an unread renewal.
One policy review this year, not none.
$59,000 stays compounding.
No rush. It keeps until you want it.
