Donation Value Calculator
What is your donation really worth? The answer depends on what you gave. This calculator answers three versions of the question: the Cash donation mode estimates your tax savings and true net cost with the itemizing check and the 60% of AGI limit built in, the Donated goods mode estimates fair market value from item type and condition, and the Match + fees mode adds an employer match and processing fees to show what the charity actually receives.
Most donation tools do one of those jobs. Cash tools cannot price a couch, goods tools know nothing about AGI limits, and neither shows the match. Here all three sit in one card, with the guardrails stated in the open instead of buried in footnotes.
Estimates for planning only, based on US federal rules. State taxes, AMT, and special situations can change the result; confirm with a tax professional.
Quick Answer
Key takeaways
- Tax savings are roughly your deductible amount times your marginal rate, and only if you itemize. Without itemizing, the itemized saving on a gift is $0.
- Cash gifts to public charities are generally deductible up to 60% of AGI. Anything above the limit carries forward for up to five years.
- Donated goods deduct at fair market value, not purchase price. This tool estimates it with condition percentages of the original price: 40% excellent, 30% good, 20% fair, 10% poor.
- An employer match is the employer gift, not yours. It multiplies the charity impact and never adds to your deduction.

Three kinds of donation, three different answers
Pick the mode that matches what left your hands. The three modes share a card because donors mix them in the same month, but each answers a different question.
Cash donation
Question: what did this gift cost me after tax? Enter the amount, your marginal rate, whether you itemize, and optionally your AGI. You get the tax saving and the net cost, with the 60% of AGI cap applied when it binds.
Donated goods
Question: what were these items worth? Enter the item type, condition, original price and quantity, plus your bracket. You get an estimated fair market value and the tax saving that value would produce if you itemize.
Match + fees
Question: what did the charity actually receive? Enter your gift, your rate, the employer match and its cap, and any processing fees. You get the total charity impact alongside your own net cost.
For a donation that is only clothing, priced piece by piece from thrift-store ranges, the dedicated donated clothing value calculator is the narrower and better tool. This page handles clothing too, inside the goods mode, when it arrives mixed with cash and matched gifts.
How to use each mode
Start on the tab that matches your gift, and leave optional fields blank rather than guessing at them. Blank is handled honestly here: no AGI means no AGI check, and no match means no match.
Cash donation. Enter the amount and your marginal rate. Set itemizing to Yes if your itemized deductions beat the standard deduction; set it to No and the mode shows the $0 itemized saving plainly instead of flattering you. Add your AGI only if you want the 60% limit tested against a large gift.
Donated goods. Choose the item type and the condition honestly. Good means sound and saleable, not nearly new. Enter what one item cost new and how many you gave. The condition percentage does the valuation, and the bracket turns the value into an estimated saving.
Match + fees. Enter your gift and your rate first. Add the match percentage and cap from your employer plan summary, and the fee your giving platform charges. The result separates three numbers donors usually blur together: what left you, what the charity netted, and what the gift cost you after tax.
The three formulas, stated plainly
Each mode runs one short formula. The rules around the formulas matter more than the arithmetic, so they are printed with it.
Deductible amount is the gift itself, reduced to $0 if you do not itemize, capped at 60% of AGI when an AGI is entered and the gift exceeds it, and then, for itemizers from 2026, reduced by 0.5% of AGI under the floor described below.
Condition percentages: excellent 40%, good 30%, fair 20%, poor 10%.
Match is your gift times the match percentage, held at the cap when a cap is entered. Fees are the gift times the fee percentage, plus any flat fee.
The cash formula follows the structure in IRS Publication 526, Charitable Contributions: a deduction times your marginal rate is an estimate of saving, not a refund, and it only exists once the gift clears the itemizing and percentage-limit gates. The goods formula is an estimator built on the Publication 526 definition of fair market value, the price a willing buyer would pay in the item current condition, which IRS Publication 561 develops in full for donated property.
Worked examples, checked against the tool
Every number below is the tool own output for the pre-filled values, so you can reproduce each one by switching to its tab and clicking Calculate.
Cash: a $1,000 gift at 24%
Enter $1,000 at a 24% marginal rate with itemizing set to Yes. Tax savings = $1,000.00 × 24% = $240.00; net cost = $1,000.00 − $240.00 = $760.00. Set itemizing to No and the saving drops to $0.00 with the net cost back at the full $1,000.00, because an itemized deduction you never claim saves nothing. Now keep Yes, raise the gift to $50,000 and add an AGI of $80,000: the 60% limit is $48,000, so the deductible amount caps there, and the 2026 floor then subtracts 0.5% of AGI ($400), leaving a deductible amount of $47,600, so the saving is $11,424.00, the net cost is $38,576.00, and the extra $2,000 carries forward for up to five years.
Goods: two pieces of furniture in good condition
Switch to Donated goods: Furniture, Good condition, original price $500, quantity 2, bracket 22%. Fair market value ≈ $500.00 × 30% × 2 = $300.00; estimated tax savings at 22% = $66.00. Note what the estimate is doing: it prices the furniture at thrift value, roughly a third of its new price in good condition, which is the honest order of magnitude for used furniture.
Match + fees: a $500 gift your employer doubles
Switch to Match + fees: a $500 gift at a 24% rate, a 100% match capped at $1,000, and a 2.9% processing fee with the flat fee left blank. Fees = $14.50, so $485.50 reaches the charity from you; the match adds $500.00; the total charity impact is $985.50. Your tax saving is $120.00 on your own gift only, so your net cost is $380.00. Add the common $0.30 flat fee and the charity total moves to $985.20, which is exactly the kind of small leak this mode exists to make visible.
The guardrails: itemizing, AGI limits, and the 2026 change
Three gates decide whether an estimated saving ever reaches your tax bill. The calculator applies the first two in cash mode and states the third openly here, because it is newer than the tool guardrail text.
Itemizing is the first gate. Charitable deductions live on Schedule A. If the standard deduction is bigger, the itemized saving is zero, and the cash mode says so when you set itemizing to No. You can model the return side of that choice with the 1040 calculator.
Percentage limits are the second gate. Cash to public charities is generally capped at 60% of AGI, and the excess carries forward up to five years, a pattern taxpayers already know from the carryforward logic in the capital loss deduction calculator. Other gift types carry their own limits under Publication 526: most noncash property to public charities sits under a 50% ceiling, and appreciated capital gain property under 30% when you deduct full fair market value. The goods mode estimates value and saving before those ceilings, so a very large goods donation still needs the Publication 526 limits checked against your AGI.
A new floor applies to itemizers from 2026. Section 70425 of the One Big Beautiful Bill Act (OBBBA) added IRC §170(b)(1)(I): for tax years beginning after December 31, 2025, an itemizer’s charitable deduction is allowed only to the extent aggregate contributions exceed 0.5% of AGI. In plain terms, the first 0.5% of your income given away earns no deduction: on an AGI of $100,000, the first $500 of giving is subtracted before the deduction is figured. The cash mode applies this floor whenever you itemize and enter an AGI, after the 60% cap; if you itemize but leave AGI blank, the result notes that the floor could not be applied.
The 2026 change is the third gate, and it cuts the other way. From tax year 2026, taxpayers who do not itemize can deduct up to $1,000 of cash contributions, or $2,000 if married filing jointly, to qualified organizations, as the IRS explains in its tips for tracking charitable donations. The cash mode models the itemized rules, where the non-itemizer saving is $0, so treat its $0 result as the itemized answer and add the 2026 cash provision on top if it applies to you. It covers cash only; donated goods still need itemizing.
One more boundary worth naming: only the deductible part of a payment counts. A $1,000 gala ticket with $200 of dinner and entertainment in return is an $800 contribution, not $1,000, whichever mode you run it through.
What competing donation calculators miss
The tools ranking for this keyword each cover a slice of the problem and stop there.
The broad deduction calculators skip the match entirely. The most complete cash competitor models filing status, AGI limits and appreciated property, then stops at your tax return. It never asks about an employer match or a processing fee, so it cannot answer the question donors in workplace giving programs actually ask: what did the charity end up with?
The goods estimators skip the tax gates. Itemized-list estimators value clothing and furniture well and export tidy records, but they apply no itemizing check and no AGI limit. A perfectly valued $300 couch still saves $0 for a non-itemizer, and a tool that prints a saving without testing that gate overstates the benefit.
The full tax engines skip the goods. Microsimulation giving tools model your whole return to find an optimal gift, which is powerful and slow, and they have no way to price a bag of clothes or a used sofa. Most donors do not need a tax model; they need three short answers they can trust.
Two honest limits of this tool. The goods percentages are rules of thumb, not appraisals: Publication 561 warns that value is what a buyer would actually pay, so cross-check anything valuable against thrift or consignment prices, and get a qualified appraisal for a single item claimed over $5,000. And the tool covers federal rules only; state treatment of charitable giving varies enough to change the net cost on larger gifts.
Frequently Asked Questions
Roughly your gift times your marginal tax rate, if you itemize: a $1,000 gift at 24% saves about $240. Without itemizing, the federal saving is usually $0.
Cash donations to public charities are generally deductible up to 60 percent of your adjusted gross income in the gift year. Donations above that carry forward for up to five years.
At fair market value: what they would sell for today. The goods mode estimates this from the original price and condition; document anything valuable with photos and receipts.
No. You deduct only what you gave; the match is your employer’s gift. It does multiply the charity impact, which the match mode shows.
You deduct your full gift; the fee just reduces what the charity nets. The match mode separates the two so you see both.
No. The IRS does not allow deductions for the value of your time or services, though mileage driven for charitable work is deductible at the standard charitable rate.
When you claim more than $5,000 for a single item or a group of similar items. The appraisal supports the value on Form 8283, which itself is required once your noncash donations for the year pass $500. Below those lines, photos, receipts and a written valuation note are the documentation that matters.
From tax years beginning after December 31, 2025, IRC §170(b)(1)(I), added by OBBBA §70425, allows an itemizer a charitable deduction only to the extent aggregate contributions exceed 0.5% of AGI. On an AGI of $100,000, the first $500 of contributions earns no deduction. This calculator subtracts the floor in cash mode after the 60% of AGI cap whenever you itemize and enter an AGI; without an AGI it cannot apply the floor and says so in the result.
From tax year 2026, yes, within limits: taxpayers who do not itemize can deduct up to $1,000 of cash contributions, or $2,000 if married filing jointly, to qualified organizations. This calculator cash mode models the itemized rules, where the saving without itemizing is $0, so add the 2026 provision on top of its result if it applies to you. It covers cash only, not donated goods.
