Charitable Giving Tax Savings Calculator
Use this calculator to determine your potential tax savings with a tax deductible gift to charity. This calculator sorts through the tax brackets and filing options to estimate the actual tax savings of your charitable gift.
How the charitable giving tax savings calculator works
It multiplies your donation by your marginal tax rate to find the tax it saves (if you itemize), then subtracts that from the gift to reveal its real after-tax cost.
Worked example: with annual donation of $5,000 and marginal tax rate of 24.00%, the charitable giving tax savings calculator shows tax savings from your gift of $1,200.
- Donation
- $5,000
- Tax savings
- $1,200
- After-tax cost
- $3,800
- Effective discount
- 24%
The formula
Tax savings = donation × marginal tax rate. After-tax cost = donation − tax savings.

Questions about the charitable giving tax savings calculator
How much do I save by donating to charity?
If you itemize, you save your marginal tax rate times the donation. A $1,000 gift at a 24% rate saves $240, so it really costs you $760.
Do I have to itemize to benefit?
Generally yes — charitable deductions only help if your total itemized deductions exceed the standard deduction. Many filers no longer itemize after the 2018 increase.
Is donating stock more tax-efficient?
Often yes — giving appreciated stock you have held over a year lets you deduct its full value and avoid the capital-gains tax you would owe if you sold it.
Is the Charitable Giving Tax Savings Calculator free to use?
Yes. Every calculator on FinCalculators is completely free, with no sign-up, login or paywall. You can run as many scenarios as you like.
