What does the estate distribution planner calculate?

The planner estimates how your estate will be distributed after taxes and fees. It calculates a net distributable estate and then allocates that amount across heirs and charities based on the percentage shares you enter.

How are taxes and fees modeled?

Taxes and fees are modeled as simple percentages of the gross estate value. The tool subtracts the tax percentage and fee percentage from the total to estimate the net distributable estate. Actual tax rules are more complex, so treat this as a planning approximation.

What if my beneficiary shares do not add up to 100%?

If the total of all beneficiary shares is greater than zero but not equal to 100%, the planner normalizes the shares proportionally so they sum to 100%. This keeps the distribution consistent while preserving the relative weights you entered.

Can I include charitable giving in the plan?

Yes. You can assign a percentage share to a charity or philanthropic fund. The planner will treat it like any other beneficiary and show the estimated net amount that would go to charitable giving.

Is this tool a substitute for legal or tax advice?

No. The estate distribution planner is an educational tool that helps you visualize potential outcomes. Estate law and tax rules vary by jurisdiction and can be complex. Always consult an attorney or qualified tax professional before finalizing an estate plan.

Can I export the distribution breakdown?

Yes. Use the Export CSV button to download a table of beneficiaries, their normalized shares, and estimated net amounts. You can import this file into a spreadsheet or share it with your estate planning team.

Estate Distribution Planner

Estimate how your estate will be distributed among heirs, charities, and taxes. Model net amounts after fees, normalize shares, and export a clear distribution breakdown you can share with your planning team.

Total estate value Estimated estate tax rate (%) Legal & administrative fees (%)

Heir 1 share (%) Heir 2 share (%) Heir 3 share (%)

Charity / philanthropic fund (%) Family trust / reserve (%) Rounding mode

Tip: Enter approximate tax and fee percentages, then adjust beneficiary shares to see how net amounts change.

Important: This planner uses simple percentage-based estimates for taxes and fees. Actual estate tax rules, exemptions, and legal costs vary by jurisdiction and situation. Use this tool for planning and discussion, and confirm details with qualified professionals.

Estate distribution formulas

Behind the scenes, the estate distribution planner uses straightforward formulas to estimate how your estate might be divided. These formulas help you understand the impact of taxes, fees, and beneficiary shares on the final amounts each person or organization receives.

1. Net distributable estate

Gross estate = Sum of all assets

Tax cost = Gross estate × (Estate tax rate ÷ 100)
Fee cost = Gross estate × (Fee rate ÷ 100)

Net distributable estate = Gross estate − Tax cost − Fee cost

The net distributable estate is the amount available to be allocated among heirs, charities, and any family trusts after estimated taxes and fees.

2. Beneficiary share normalization

Total raw share = Heir1% + Heir2% + Heir3% + Charity% + Reserve%

Normalized share for beneficiary i =
  (Raw share i ÷ Total raw share) × 100

If your raw shares do not add up to exactly 100%, the planner rescales them proportionally so the normalized shares sum to 100%. This preserves the relative weights you chose while ensuring a consistent distribution.

3. Beneficiary amount calculation

Beneficiary amount i =
  Net distributable estate × (Normalized share i ÷ 100)

Each beneficiary’s estimated amount is calculated by applying their normalized share to the net distributable estate. Optional rounding modes can adjust these amounts to whole dollars for easier communication.

These formulas are intentionally simple. Real-world estate planning may involve progressive tax brackets, exemptions, special rules for charitable giving, and complex ownership structures. Use the planner as a starting point to explore scenarios and prepare for conversations with your advisors.

Planning your estate distribution across generations

Estate planning is about more than drafting a will. It is about deciding how your wealth will support the people and causes you care about, and how to do so in a way that is clear, fair, and tax-efficient. The estate distribution planner helps you visualize how your estate might be divided among heirs, charities, and family trusts after estimated taxes and fees.

Clarifying your goals

Before you think in percentages, it helps to clarify your goals. Do you want to prioritize financial security for a spouse or partner? Equal treatment among children? A meaningful gift to a charity or foundation? A reserve for future generations through a family trust? Writing these goals down makes the numbers more meaningful and reduces the chance of misunderstandings later.

Once your goals are clear, you can translate them into shares. For example, you might decide that 40% of your net estate should go to a surviving spouse, 35% split between children, 15% to a family trust, and 10% to charitable giving. The planner lets you test these ideas and see the approximate dollar amounts they imply.

Understanding taxes and fees

Taxes and fees can significantly change what your heirs actually receive. Estate taxes may apply only above certain thresholds, and some assets may be treated differently. Legal and administrative fees can include probate costs, attorney fees, and executor compensation. In this tool, you model these costs as simple percentages of the gross estate value. While this is not a substitute for detailed tax analysis, it helps you see how sensitive your plan is to different assumptions.

For instance, a 20% estate tax and 3% fee rate on a $1.5 million estate reduces the net distributable amount to roughly $1.155 million. Seeing that number can prompt useful questions: Should you explore strategies to reduce taxable estate value? Would charitable giving or lifetime gifts change the picture?

Worked example

Imagine an estate with a gross value of $1,500,000. You estimate a 20% estate tax rate and 3% in legal and administrative fees. You set the following raw shares:

Heir 1 (spouse): 40%
Heir 2 (child): 35%
Heir 3 (child): 15%
Charity: 10%

The total raw share is 100%, so no normalization is needed. The planner calculates a net distributable estate of $1,155,000 and then allocates that amount according to the shares. Heir 1 would receive about $462,000, Heir 2 about $404,250, Heir 3 about $173,250, and the charity about $115,500. If you adjust the tax or fee assumptions, you immediately see how each amount changes.

If your raw shares did not add up to 100%—for example, 50% for a spouse, 30% for children, and 10% for charity—the planner would normalize them so the relative proportions are preserved. This avoids accidental over-allocation and keeps the distribution coherent.

Practical tips for using the planner

Start with conservative tax and fee estimates, then refine them after speaking with a professional.
Use the rounding options when you want clean, whole-dollar amounts that are easier to communicate in family discussions.
Export the CSV breakdown and bring it to meetings with your attorney or advisor as a visual starting point.
Experiment with different charitable shares to see how philanthropy affects the amounts going to heirs.
Consider modeling a separate “family trust” share if you want to preserve capital for future generations.

Estate planning can feel emotional and complex, but seeing the numbers laid out clearly often reduces anxiety. The estate distribution planner does not replace legal documents or professional advice, yet it gives you a concrete way to explore scenarios, align your plan with your values, and prepare for more productive conversations with the people who will help you implement your legacy.

Frequently Asked Questions

How precise are the tax and fee estimates?

The planner uses simple percentage-based estimates. Real estate tax calculations may involve thresholds, exemptions, and different rates for different asset types. Treat the results as directional rather than exact and confirm with a tax professional.

Can I model more than three heirs?

This version focuses on three heirs plus a charity and optional reserve. If you have more beneficiaries, you can group similar heirs together or export the CSV and build a more detailed model in a spreadsheet.

What happens if I leave some share fields blank?

Blank or zero shares are ignored. The planner sums all positive shares and normalizes them to 100%. This means you can start with just one or two beneficiaries and add more over time.

How does rounding affect the results?

Rounding changes the displayed amounts but not the underlying net estate calculation. If you choose rounding to the nearest dollar or rounding down, the individual amounts may not sum exactly to the net estate due to rounding differences, but they will be close.

Can I use this tool for cross-border estates?

Cross-border estate planning involves additional legal and tax considerations. This tool does not model specific jurisdictional rules. You can still use it to explore high-level scenarios, but you should work with professionals familiar with the relevant countries.

Is my data stored permanently?

The planner uses localStorage briefly to restore your last inputs after a refresh so it can auto-recalculate. After the calculation runs, the stored inputs are cleared. No data is sent to external services unless you have enabled analytics or ads via the cookie banner.
