What Is an Estate Tax Calculator?
This calculator estimates federal estate tax owed on an estate exceeding the federal exemption amount, using a simplified flat top-rate approximation. The US federal estate tax only applies to estates above a large exemption threshold, which most estates never reach.
How to Use the Estate Tax Calculator
- Enter the total estate value.
- Enter the applicable federal exemption amount for the relevant tax year.
- View the estimated tax on any amount exceeding the exemption.
2024 Federal Estate Tax Exemption
For 2024, the federal estate tax exemption is $13.61 million per individual (effectively double for married couples with proper planning). Estates below this threshold owe no federal estate tax. The top federal estate tax rate is 40%.
Simplified Estate Tax Formula
This is a simplified approximation using the top marginal rate. The actual federal estate tax uses a graduated rate schedule below 40%, so this calculator provides a conservative (upper-bound) estimate for amounts modestly above the exemption.
Worked Example
Taxable amount: $15,000,000 − $13,610,000 = $1,390,000
Estimated tax (40% approximation): $1,390,000 × 0.40 = $556,000
Important Limitations
- Most states also have their own estate or inheritance taxes with different (often much lower) exemption thresholds — this calculator covers federal tax only.
- The actual federal rate schedule is graduated, not flat 40%, so this is a simplified upper-bound estimate.
- Complex estate planning (trusts, gifting strategies, marital deductions) can significantly change actual tax owed — always consult an estate planning attorney or tax professional.
