The Cost of Dying Without a Will
Intestacy — dying without a valid will — triggers statutory distribution rules that may not match wishes, delays estate settlement by months or years, produces legal fees for court-appointed administrators, and often results in asset loss through suboptimal distribution. Research suggests typical intestacy produces 3-8% asset loss compared to well-structured will plus probate delay costs of 1,000-5,000. Will setup costs typically 100-500 — massively positive expected value for anyone with meaningful estate.
Sources of Intestacy Loss
Statutory distribution may bypass unmarried partners entirely (common intestacy issue). Assets may transfer to unintended heirs (distant relatives over preferred beneficiaries). Property may be sold suboptimally to split between heirs. Court-appointed administrator fees 2-5% of estate. Probate delays 6-24 months during which assets may depreciate. Litigation between potential heirs in 10-15% of intestate estates. Specific tax consequences may be worse without planning. Combined impact typically 5-10% of estate value plus delay costs.
Worked Example for Moderate Estate
Will cost 250. Estate value 500,000. Intestacy loss 5%. Probate delay 2,000. Intestacy asset loss 25,000. Total intestacy cost 27,000. Will net saving 26,750. The 250 will investment produces over 100x return in expected value. Larger estates see proportionally larger intestacy losses. Smaller estates still benefit as probate delay cost is fixed and will avoids it regardless of asset size. Positive expected value for virtually any adult with assets.
What the Calculator Does Not Model
Specific jurisdictional differences in intestacy rules (huge variation). Complex family situations affecting intestacy outcomes significantly. Specific asset types with different intestacy treatment (retirement accounts often bypass probate regardless). Cost of will updates as life circumstances change. Legal complexity for business owners or international assets requiring more expensive wills. The calculator shows general framework; specific jurisdictional legal advice necessary for real planning.
Will Creation Options
Online will services (Trust and Will, LegalZoom): 100-200 for simple wills. Solicitor/attorney drafted: 200-800 for standard, 1,500-5,000 for complex estates. Joint wills (couples): 300-600 combined. Estate planning packages (will plus trust plus power of attorney): 800-3,000. Free options often available for specific situations (military, basic wills in some jurisdictions). Pick approach matching estate complexity — simple situations work with DIY/online; complex situations warrant attorney.
Will at $250 on $500,000 estate saves $26,750.00 versus intestacy.

Sources & Methodology
Methodology
Intestacy asset loss multiplies estate value by loss percent. Total intestacy cost adds probate delay. Net saving subtracts will cost from total. Results are estimates.
