Most people equate 'estate planning' with 'getting a will.' That's about 25% of what you actually need. A complete estate plan addresses: who decides if you can't speak for yourself (POA, healthcare directive), who gets your stuff when you die (will, beneficiaries, trusts), how your stuff transfers (probate vs. non-probate assets), what happens to your digital life, what your family needs to know.
The decisions you make in estate documents take effect at the worst moment — when you're incapacitated or deceased and your family is grieving. Doing the planning now prevents the family conflicts, expensive mistakes, and legal battles that uplanned estates create.
Cost reality: a comprehensive estate plan from a licensed attorney costs $500-$5,000 depending on complexity. For most middle-class retirees, $750-$1,500 covers the core package. That's a one-time cost. The lifetime savings (in tax + probate fees + family stress) is typically 10-100x.
