How to use this calculator

  1. Enter values for the scenario and jurisdiction you are testing.
  2. Check rates, time periods, and dollar amounts carefully.
  3. Select Calculate or change an input and calculate again.
  4. Review the main estimate together with every supporting result.
  5. Use Reset to restore the example assumptions.

Formula

Net estate = gross estate − deductions. Taxable estate = max(0, net estate − exemption). Estimated tax = taxable estate × entered rate.

What the result means

After-tax estate value is the modeled net estate after the estimated transfer tax. Supporting results expose the taxable base and tax amount.

This simplified estimate does not model graduated rates, elections, credits, portability, marital or charitable deductions, or beneficiary-level inheritance tax.

Example calculation

A $5,000,000 estate with $500,000 of deductions and a $3,000,000 exemption has a $1,500,000 taxable estate. At 20%, estimated tax is $300,000 and after-tax value is $4,200,000.

Tips for better results

  • Confirm the valuation date and asset values.
  • Use only legally supportable deductions.
  • Enter rules for the correct year and jurisdiction.
  • Test both current-law and sunset scenarios.
  • Review liquidity separately from total net worth.

Frequently asked questions

Why are the exemption and tax rate editable?

Estate tax rules change by jurisdiction and year, so the tool does not hardcode a legal threshold.

What belongs in estate deductions?

Use obligations or deductions appropriate to your scenario after confirming their legal treatment.

What is the liquidity shortfall?

It is estimated tax minus liquid funds available, floored at zero.

Does a taxable estate always mean tax is owed?

Not necessarily; credits, elections, deductions, and filing rules can change actual liability.

Does this include inheritance tax paid by beneficiaries?

No. Beneficiary-level inheritance tax requires a separate jurisdiction- and beneficiary-specific analysis.
