It’s a powerful first step in estate planning — completely free and private.
What Is an Estate Tax Calculator?
An estate tax calculator is a free online tool that estimates the federal estate tax liability of a deceased person’s estate. You provide the gross value of all assets (real estate, investments, business interests, life insurance proceeds, etc.), subtract allowable deductions (mortgages, administrative expenses, charitable gifts, and the unlimited marital deduction), and the calculator determines the taxable estate. It then subtracts the applicable exclusion amount (the “exemption,” $13.99 million per individual in 2025) and applies the graduated federal estate tax rates. The result is an approximate tax bill that can guide your estate planning decisions. It does not account for state‑level estate or inheritance taxes, which vary widely.
How to Use the Estate Tax Calculator
Enter the Gross Estate
Sum the fair market value of all assets — real estate, bank accounts, stocks, life insurance, and business interests.
Add Deductions & Marital Status
Input any debts, funeral expenses, charitable bequests, and the marital deduction if leaving assets to a U.S. citizen spouse.
View the Estimated Tax
Instantly see the taxable estate, the exemption amount applied, and the projected federal estate tax — no sign‑up required.
How the Estate Tax Calculation Is Performed
The calculator follows IRS Form 706 logic. First, it computes the taxable estate = gross estate – allowable deductions. Then it calculates the tentative tax on the taxable estate using the unified rate schedule (18% to 40% brackets). Finally, it subtracts the unified credit (equivalent to the exemption amount) to arrive at the net estate tax. For married individuals, the unlimited marital deduction can reduce the taxable estate to zero if all assets pass to the spouse; the calculator also supports portability of the unused exemption. All calculations are performed locally in your browser — your financial data stays private.
Core Calculation Steps
Taxable Estate = Gross Estate – Deductions
Tentative Tax = Progressive Rate × Taxable Estate
Net Tax = Tentative Tax – Unified Credit
For 2025, the unified credit effectively exempts the first $13.99 million per individual.

Federal Estate Tax Exemption & Rates
2025 Exemption
Each individual can pass $13.99 million free of federal estate tax. Married couples can shield up to $27.98 million with portability.
Graduated Rates
Taxable amounts above the exemption are taxed at rates starting at 18% and rising to 40% for amounts over $1 million.
Unlimited Marital Deduction
Assets left to a U.S. citizen spouse are fully deductible, deferring all estate tax until the surviving spouse’s death.
What Counts as Gross Estate?
The gross estate includes the fair market value of everything you own or have an interest in at death: real estate, bank accounts, stocks, bonds, business interests, retirement accounts, life insurance proceeds (if you owned the policy), annuities, and even certain gifts made within three years of death. It’s a comprehensive snapshot. The calculator lets you enter a single total or add up major categories to arrive at a realistic gross estate value.
Deductions That Reduce the Taxable Estate
Debts & Expenses
Mortgages, credit cards, funeral costs, and estate administration expenses are subtracted from the gross estate.
Charitable Bequests
Amounts left to qualified charities are fully deductible, allowing you to lower your taxable estate while supporting causes you care about.
Marital Deduction
Property passing to a surviving U.S. citizen spouse is not taxed at the first death — the most powerful deduction available.
Using the Calculator to Explore Gift & Estate Strategies
Lifetime gifts reduce your gross estate and use up part of your exemption. The calculator can’t model a full gift history, but you can decrease your gross estate by the value of gifts already made to see the effect. Also, by toggling the marital deduction you can see how much tax is deferred until the second spouse’s death — a critical insight for couples deciding on a credit shelter trust or outright spousal bequest.
Portability: Doubling the Shield
Portability allows a surviving spouse to use any exemption that the deceased spouse did not use. For example, if the first spouse dies with a $5 million estate (well under the exemption), the remaining $8.99 million exemption can be transferred to the survivor, who then has up to $22.98 million exempt. The calculator can simulate this by allowing you to enter an additional portable exemption amount. This makes a huge difference for wealthy couples and is one of the most valuable estate planning elections.
Example Estate Tax Calculation
James has a gross estate of $18 million. He has $1.2 million in debt and leaves $500,000 to charity. He is unmarried. His taxable estate is $18M – $1.2M – $0.5M = $16.3 million. After subtracting the $13.99M exemption, $2.31 million is subject to tax. Applying the unified rate schedule gives a tentative tax of roughly $870,000, and after the unified credit, the net tax is about $870,000. The calculator shows this breakdown instantly, helping James’s family plan for liquidity needs.
How to Use the Results in Your Estate Plan
If the calculator shows a substantial tax, work with an estate planning attorney to implement strategies like irrevocable trusts, annual exclusion gifts (up to $18,000 per recipient in 2025), or charitable remainder trusts. You can also model the effect of reducing your gross estate by making large gifts today — just subtract the gift amount from your gross estate input. The calculator gives you the numbers; your attorney will help you act on them.
Factors That Affect Estate Tax Liability
- 💰 Gross value of all assets
- 📊 Debts and administrative deductions
- 📅 Charitable gifts and bequests
- 👫 Marital status and citizenship of spouse
- 📈 Lifetime taxable gifts (using exemption)
- 📉 State estate or inheritance tax (separate)
- 💲 Portability election
- 🏦 Valuation discounts for certain assets
Detailed Couple’s Scenario
Scenario: Married couple, total gross estate $25 million, $2 million in debts, leaving entire estate to each other (no charitable bequests). Each spouse has their own $13.99M exemption. First death: taxable estate is $23M but marital deduction reduces taxable to $0. No tax owed. At second death, if no portability, taxable estate is $23M minus $13.99M exemption = $9.01M taxed. Tax ≈ $3.2M. With portability, the surviving spouse can add the first spouse’s unused exemption, covering the entire $23M — zero tax.
- ✅ Scenario 1: No portability — estimated tax at second death ≈ $3,200,000
- ✅ Scenario 2: With portability — estimated tax $0
- ✅ The calculator shows the huge value of electing portability.
