Your estimated tax savings: $0.00
Understanding Charitable Tax Deductions
Making charitable donations is a rewarding act, and the U.S. tax system offers incentives for taxpayers who give generously.
The IRS allows individuals to deduct qualified charitable contributions from their taxable income, effectively reducing their tax liability.
This calculator helps you estimate the potential tax savings based on your income, donation amounts, and tax bracket.
What Qualifies for a Deduction?
To be deductible, contributions must be made to qualified organizations. These are typically government entities,
religious organizations, educational institutions, hospitals, certain non-profits, and veterans' organizations.
You generally cannot deduct contributions made to specific individuals, political campaigns, or non-qualified organizations.
Types of Contributions:
Cash Contributions: This includes money, checks, credit card payments, and electronic fund transfers. For cash donations, you generally need reliable written records, such as a bank record or a written communication from the charity, showing the organization's name, date, and amount.
Non-Cash Contributions: This covers a wide range of donated property, such as clothing, furniture, vehicles, stocks, and artwork. The deduction for non-cash donations is generally limited to the fair market value (FMV) of the property at the time of the donation. For items valued over $500, you might need a qualified appraisal.
AGI Limitations
The IRS places limits on the amount of charitable contributions you can deduct in a single tax year.
These limits are typically based on your Adjusted Gross Income (AGI).
Cash Contributions: You can generally deduct cash contributions up to 60% of your AGI.
Non-Cash Contributions: Deductions for certain non-cash contributions (like appreciated property held for more than a year) are generally limited to 30% of your AGI. Other non-cash contributions may be limited to 50% of AGI. For simplicity, this calculator applies a combined limit.
If your contributions exceed these limits in a given year, you may be able to carry forward the excess contributions to future tax years, subject to the same limitations.
How the Calculator Works
This calculator estimates your potential tax savings by considering:
The total amount of your deductible contributions (cash and non-cash, subject to AGI limits).
Your marginal tax rate, which is the rate applied to your last dollar of income.
The calculation estimates the tax savings as:
Total Deductible Contributions * Your Marginal Tax Rate
Note that this is an estimation. Actual tax benefits depend on your specific tax situation, whether you itemize deductions, and the specific rules applicable to your donations.

var deductibleContributions = totalContributions; // Start with total
// AGI Limits (simplified for this calculator)
// For simplicity, we apply a general limit. In reality, cash and non-cash have different limits.
// For example, cash can often be up to 60% of AGI, while appreciated non-cash property might be 30%.
// We'll use a conservative combined limit here, but acknowledge this simplification.
var agiLimit60 = agi * 0.60; // 60% limit for cash
var agiLimit30 = agi * 0.30; // 30% limit for certain non-cash
// Determine the deductible amount considering limits
var deductibleCash = Math.min(cashContributions, agiLimit60);
var deductibleNonCash = Math.min(nonCashContributions, agiLimit30);
// If total non-cash deductions plus the cash deductions (which would be limited first in complex scenarios)
// exceed their respective limits, we need to adjust.
// A common scenario is that cash is prioritized.
var finalDeductibleAmount = 0;
if (cashContributions <= agiLimit60) {
// If all cash contributions are within the 60% limit
finalDeductibleAmount = cashContributions + Math.min(nonCashContributions, agiLimit30);
} else {
// If cash contributions exceed the 60% limit, we only deduct up to that limit
// and then see if there's room for non-cash within the *overall* AGI limit or
// if the non-cash itself is limited by its own AGI limit (30% or 50%).
// For simplicity in this calculator: We'll cap the total at 60% of AGI,
// prioritizing cash if possible, but acknowledging non-cash has its own stricter limits.
// A more accurate model would be complex. This is a common simplification.
finalDeductibleAmount = Math.min(totalContributions, agiLimit60); // Cap total deduction at 60% of AGI as a common upper bound
// More precise: finalDeductibleAmount = Math.min(cashContributions, agiLimit60) + Math.min(nonCashContributions, Math.min(agiLimit30, agi – Math.min(cashContributions, agiLimit60)));
// However, we will simplify and cap at 60% of AGI if the total exceeds it.
}
// Ensure the final deductible amount doesn't exceed the actual contributions made.
finalDeductibleAmount = Math.min(finalDeductibleAmount, totalContributions);
