About this tool

What the Private Foundation Payout Calculator does

US private non-operating foundations must make qualifying distributions roughly equal to 5% of the average value of their investment assets each year. The minimum investment return excludes a cash allowance (usually 1.5%) and is reduced by the excise tax on net investment income. Undistributed amounts must be paid out by the end of the following year.

It also works as a foundation payout rate calculator or a private foundation 5 percent rule calculator.

Formula

  • Minimum investment return = 5% × (assets − debt) × (1 − cash allowance)
  • Distributable amount = minimum investment return − excise tax
  • Shortfall = distributable amount − qualifying distributions

Worked example

Using the starting values in the calculator above:

Input Value
Average monthly fair market value of investment assets $20,000,000
Acquisition debt on those assets $0.00
Cash held for charitable activities 1.5%
Net investment income $900,000
Excise tax rate 1.39%
Grants paid $820,000
Reasonable charitable administrative expenses $110,000
Excess distributions carried over $0.00
Result Value
Distributable amount $972,490
Shortfall (negative = excess) $42,490
Minimum investment return (5%) $985,000
Excise tax $12,510
Qualifying distributions incl. carryover $930,000
Payout rate on assets 4.65%

How to read the result

A shortfall must be distributed by the end of the next tax year to avoid an excise tax on undistributed income.

Investment management fees are not qualifying distributions; charitable administrative costs usually are.

Not tax advice. Distribution rules have detail and exceptions; confirm with your accountant and the Form 990-PF instructions.
