How It Works
Our Donor Advised Fund (DAF) calculator helps you quantify the tax advantages of contributing to a DAF, especially when employing a 'bunching' strategy. See how much you can save on federal income tax and avoid capital gains tax on appreciated stock by consolidating charitable contributions into a single year, particularly relevant for the 2026 tax year and beyond.
The calculator estimates federal income tax savings by multiplying your bunched charitable deduction by your estimated marginal tax rate. For appreciated stock, it calculates avoided long-term capital gains tax at either 15% or 20% (depending on income thresholds for 2026) on the fair market value of the contributed shares, assuming a zero cost basis for simplicity.
A common mistake is not considering your Alternative Minimum Tax (AMT) liability, as charitable deductions don't reduce AMT. Also, ensure you have sufficient itemized deductions to exceed the standard deduction (projected to be around $32,000 for married filing jointly in 2026) to fully benefit from bunching.
Example: DAF Bunching with Appreciated Stock for 2026
- 1 Input: Enter your anticipated taxable income for 2026, the fair market value of appreciated stock you plan to donate, your estimated cost basis for that stock, and your planned charitable contribution amount.
- 2 Calculate: The calculator will determine your marginal income tax bracket for 2026 based on your taxable income, estimate federal income tax savings from the deduction, and calculate avoided capital gains tax on your appreciated stock.
- 3 Result: View your total estimated tax savings from both federal income tax deduction and avoided capital gains tax. The calculator will also show the impact of bunching on your itemized deductions for the 2026 tax year.
- 4 Context: This provides a clear picture of the financial benefits of using a DAF, especially with appreciated assets and a bunching strategy. Remember that state and local tax implications are not included in this federal-focused calculation, and individual tax situations can vary.
