Missouri Estate Planning Cost Calculator

In Missouri, use $1,500-$5,000 as the attorney-drafted range for a will, powers of attorney, healthcare directive, and trust review. Missouri online estate-planning forms often run $100-$500 before state-specific attorney review. Don't price the package without comparing it to the $40,000 small-estate threshold.

Missouri has no listed state estate tax, so the main transfer-tax screen is the $13,990,000 federal exemption for 2026. The working probate citation is RSMo § 473.153, so high-value estates should check both transfer-tax exposure and probate administration cost before choosing a will-only plan.

A simple Missouri will package normally includes the will, durable power of attorney, healthcare directive, HIPAA authorization, executor nomination, and guardian nominations if you have minor children. It is usually the lower-cost option when probate exposure is modest and assets already pass by joint title or beneficiary designation.

A trust package costs more because it adds the revocable trust, pour-over will, trust certificate, and asset-funding work. The attorney should review deeds, bank and brokerage accounts, life insurance, retirement beneficiaries, and any transfer-on-death or payable-on-death designations so the documents do not contradict each other.

Missouri's small-estate threshold is $40,000, and affidavit availability is recorded as available. If your estate is above that number, a funded trust can avoid a 6-12 months probate path.

The Missouri homestead exemption is $15,000 under Mo. Rev. Stat. § 513.475. That asset-protection number matters when you're choosing between a basic $100-$500 document bundle and a $1,500-$5,000 attorney plan.

A Missouri plan usually includes a will, durable power of attorney, healthcare directive, and trust decision tied to the $40,000probate threshold. The calculator uses those 4 document categories because that's where the largest fee swing appears.

Before asking for quotes, gather deeds, mortgage statements, account statements, business records, beneficiary forms, prior wills or trusts, divorce orders, prenuptial agreements, and a current list of beneficiaries and decision-makers. The quote is more reliable when the attorney can see which assets need probate avoidance work.

Online templates are riskiest in Missouri when the estate involves a second marriage, disabled beneficiary, minor children, unequal distributions, creditor concerns, Medicaid planning, business succession, or property in another state. In those cases, the legal review is usually the value, not the blank form.

Missouri cost and deadline signals is the right starting point because statewide law sets the baseline, while the facts of your estate plan determine the actual risk band. Use the calculator before you compare attorney quotes, court options, or settlement choices.

Factors that affect the Missouri estimate usually comes down to three inputs: the amount at stake, the deadline or statutory rule, and whether the matter can be resolved before a contested filing. The calculator keeps those inputs separate so the result is easier to challenge.

County variation matters in Missouri because clerk practices, hearing calendars, and local filing steps can change the time cost even when the statewide rule is fixed.
