Is this the same as my full-year tax estimate?

No. This looks at one trade in isolation. For your total tax liability across all trading profit and losses this year, use the day trading tax liability estimator instead.

How much of this winning trade should I set aside for taxes before I reinvest or withdraw it?

Q: How much of this winning trade should I set aside for taxes before I reinvest or withdraw it?

Multiply the trade's profit by your combined federal and state marginal tax rate. That dollar amount is a reasonable estimate to set aside immediately, before deciding what to do with the rest.

You don't need a better indicator. You need a process you'll actually follow at 9:31am.

Most short-term trading profit is taxed as ordinary income at your marginal rate, not the lower long-term capital gains rate.

How this is calculated

The set-aside amount equals this trade's profit multiplied by your combined federal and state marginal tax rate.
This applies to a single realized profit, right after the trade closes. For your total tax picture across the whole year, use the day trading tax liability estimator or the quarterly estimated tax payment calculator instead.
This does not account for offsetting losses elsewhere in your account, the $3,000 annual limit on deducting net capital losses against ordinary income, wash sale rules, or your full tax return.
Use your own confirmed marginal tax bracket. A rough placeholder rate can make this estimate meaningfully wrong in either direction.

Risk & liability disclaimer: This calculator produces a rough estimate based on the numbers you enter and generic ordinary-income tax treatment. It is not tax advice and does not account for your full tax situation, deductions, other income, filing status brackets, or state-specific rules.
