What it does

Gifts cost less than their face. A deductible donation at a 22 % bracket returns nearly a quarter in tax savings for itemizers.

The tool above prices the gift. Five thousand dollars at 22 % saves $1,100.00, so the net cost is $3,900.00, or $91.67 a month of value.

Brackets set the discount. Ten percent brackets save dimes per dollar, thirty seven percent brackets save more than a third, all before state effects.

Itemizing gates the gain. Gifts past the standard deduction save per dollar, while standard deduction filers may need bunching across years.

Stock gifts stretch further. Appreciated shares skip capital gains plus earn the deduction, beating cash from savings.

How to use

  1. Enter gift amount.
  2. Enter marginal bracket: 22 suits many filers.
  3. Read savings first.
  4. Read net cost next.
  5. Read monthly value.
  6. Keep receipts and file correctly.

Formula

Savings = gift x bracket / 100. Net = gift - savings. Monthly = savings / 12.
gift
Cash gift amount.
bracket
Marginal tax bracket, in percent.

Bracket is the marginal federal rate from 10 to 37 %. Real savings need itemizing past the standard deduction.

Worked example

Example: $5,000 gift at 22 %

Defaults: $5,000 gift at a 22 % bracket. These are also the default values, so the page opens on this answer.

  1. Gift: $5,000.
  2. Bracket: 22 %.
  3. Savings: 5000 x 0.22 = $1,100.00.
  4. Net: 5000 - 1100 = $3,900.00 cost.
  5. Monthly: 1100 / 12 = $91.67.
  6. Tool shows $1,100.00, $3,900.00 net cost, $91.67 per month.

Savings are 10000 x 0.24 = $2,400.00. Net is $7,600.00. Monthly is 2400 / 12 = $200.00.

$1,000 at 12 %?

Savings are 1000 x 0.12 = $120.00. Net is $880.00. Monthly is $10.00.

Questions

Tax savings?

Multiply the gift by the bracket. Here 5000 x 0.22 = $1,100.00.

True gift cost?

Subtract savings from the gift. Here 5000 - 1100 = $3,900.00 net cost.

Which bracket?

Use the marginal bracket on the last dollars, often 10 to 37 %. Standard deduction takers may gain nothing extra.

Must I itemize?

Itemizers past the standard deduction gain per dollar. Non itemizers need bunching or donor funds.

Cash or stock?

Yes. Cash, stock, and QCD rules differ, with appreciated stock often winning.

State taxes included?

No. State rules and AMT need pro advice.
