I see a lot of people miscalculate their gross distribution from their IRAs when they have a specific net /after tax amount they need.

For example, you want to take a net/after tax distribution of $5,000 from your IRA, and you are in the 28% tax bracket. You want to calculate how much your gross distribution should be so that you end up with a net/after tax distribution of $5,000.

A 28% tax would be represented in decimals as 0.28.

First subtract 1 -(minus) 0.28 on your calculator and you get = 0.72

Take the net distribution you would like so in this case $5,000 and divide it by 0.72 = $6,944.44

So if you take a distribution from your IRA for $6,944 and have 28% or $1,944.32 withheld for taxes, you would net $5,000 after tax from your IRA.

$6,944 was the gross distribution-$1,944.32 was the 28% tax withholding =$5,000 Net IRA distribution after tax.

Here is the formula for this scenario:
1-0.28 = 0.72

$5,000/0.72 = $6,944.441 – tax bracket converted to a decimal = X

Net distribution/X = gross distribution.

A lot of people start with the net distribution ($5,000 in this example) and multiply it by the tax rate (28% in the example). If you do this you get $1,400.

They then add the $1,400 plus the $5,000 to come up with $6,400.

The problem is if you request a gross distribution of $6,400 multiplied by 28% it equals $1,792, and you end up with a net distribution of $4,608 which was not the desired outcome.

Formula: gross = net ÷ (1 − rate), where rate is expressed as a decimal (e.g., 28% → 0.28). This tool is for illustration only and does not provide tax advice. Actual withholding rules for IRAs (e.g., default federal 10% and state rules) may differ. Consult your tax professional.
