Formula

Net beneficiary income = trust balance × income yield × distribution share × (1 − tax rate)

What the result means

The main result is cumulative after-tax beneficiary income across the selected forecast period.

This is a planning estimate, not tax, legal, or investment advice. Actual treatment depends on jurisdiction, trust terms, holding periods, and individual circumstances.

Example calculation

A $750,000 trust yielding 4%, distributing 80% of income, taxed at 25%, and growing 2% for 10 years produces $18,000 of first-year net income and about $197,094 cumulatively.

Tips for better results

  • Use a sustainable yield estimate, not total return.
  • Confirm whether income is actually required to be distributed.
  • Model beneficiary and trust-level tax separately when needed.
  • Run a zero-growth case for a conservative comparison.

Frequently asked questions

Is undistributed portfolio income added back to the trust?

Yes. The model retains the undistributed share of income in the trust balance.

Is tax charged to the trust or beneficiary?

The entered tax rate is applied to distributed income as a beneficiary-level planning estimate.

Why is yield separate from asset growth?

Yield generates income, while asset growth changes principal value; combining them would obscure distributions.

Can the trustee distribute more than portfolio income?

Not in this model. Use the withdrawal-schedule calculator for principal distributions.

Does this forecast account for changing tax brackets?

No. It uses one effective rate for all modeled years.
