Donor-Advised Fund Calculator

A donor-advised fund (DAF) lets you make a single, deductible charitable contribution today, then grant the money to charities of your choice over time. Compare giving cash versus donating appreciated stock — and see why what you give often matters as much as how much.

What it is

A charitable investment account at a sponsor (Fidelity Charitable, Schwab Charitable, NPT, community foundations). Contributions are irrevocable charitable gifts — you take the deduction now, then recommend grants to qualified 501(c)(3) charities later.

How it works

Contribute cash, appreciated securities, or other assets. Take an income-tax deduction for the year of contribution (subject to AGI limits). Assets grow tax-free inside the DAF. Recommend grants on your timeline — this year, next year, or over decades.

Where it fits

High-income years (liquidity event, big bonus, Roth conversion). "Bunching" several years of giving into one to clear the standard deduction. Donating low-basis stock to wipe out an embedded gain. Building a multi-generational giving vehicle without the cost of a private foundation.

The Gift

The amount you intend to give to charity.

Original purchase price. Assumes long-term holding (> 1 year).

The Bottom Line

Donating appreciated stock in-kind delivers the same gift to charity at the lowest after-tax cost.

Talk through your giving plan

What assets to consider giving

  • Long-term appreciated public stock or ETFs — the cleanest win. Deduct FMV, skip the gain entirely.
  • Concentrated low-basis positions — trim risk and capture full FMV deduction in one move.
  • RSU/ISO stock held > 1 year — same treatment as any LTCG security.
  • Pre-IPO or restricted shares — possible but requires a qualified appraisal and sponsor acceptance.
  • Privately-held business interests, real estate, crypto — many DAF sponsors accept these; appraisal and timing rules apply.
  • Cash — simplest and gets the highest AGI limit (60%). Use when you have no embedded gains worth harvesting.
  • Avoid donating losers. Sell first, claim the loss, then donate the cash — you get both tax breaks.
  • Avoid short-term holdings. Deduction is limited to basis, not FMV.

How this works

Cash donation generates a deduction equal to the gift, valued at your combined federal + state marginal rate. Selling stock first triggers capital gains tax (LTCG + NIIT + state) on the appreciation, leaving less to donate and a smaller deduction. Donating stock in-kind to a public-charity DAF lets you deduct full FMV and permanently avoid the embedded gain — the charity inherits your zero-cost basis but pays no tax when it sells.

AGI limits for gifts to a DAF: 60% of AGI for cash, 30% of AGI for long-term appreciated securities at FMV. Anything above the limit carries forward up to 5 years. The deduction only matters if you itemize — "bunching" several years of gifts into one DAF contribution is a common way to clear the standard deduction.

Important Disclosure: This calculator provides rough estimates for educational and illustrative purposes only and does not constitute tax, legal, financial, or investment advice. Rubiq Financial Partners is not a tax advisor, CPA, or attorney, and does not provide tax preparation, legal, or accounting services. The model assumes long-term holding, full itemization, that the entire deduction is usable in the contribution year (subject to the displayed AGI check), state conformity to federal charitable rules, and ignores AMT, Pease-style limits, phase-outs, and the alternative minimum tax. Actual tax outcomes depend on many factors not captured here, including individual taxpayer circumstances, AGI limitations, carryforward rules, and state-by-state tax conformity. Tax rates, charitable deduction limits, and DAF-related rules are subject to legislative change. Donor-Advised Fund contributions are irrevocable — once contributed, assets cannot be returned to the donor. DAF sponsors typically charge administrative and investment management fees that reduce account growth and are not reflected here. Investment performance inside the DAF is not guaranteed and may produce returns lower than illustrated. Past performance does not guarantee future results. Always consult with a qualified tax advisor, attorney, and financial advisor before executing any charitable giving strategy.
