About the Capital Gains Estimator
The Capital Gains Estimatoroffers a clear way to measure and compare the tax effects of selling investments. By analyzing your holdings, the tool calculates your projected taxes for each potential sale and displays possible outcomes for short-term and long-term gains. This feature is available in Quicken tiers that include investment tracking, helping you make informed decisions about when and how to sell shares for the greatest financial advantage.

The setup process helps you prepare for informed investment decisions before making sales. To begin using the Capital Gains Estimator, follow these steps:

Reviewing and Refining Results
Once you’ve selected your securities and adjusted your tax rates, the Capital Gains Estimator provides a detailed overview of the potential tax implications of selling your investments. You can fine-tune your results by making adjustments to the number of shares, tax rates, or security prices. Here’s how to review and refine your estimates for more accurate decision-making.
Review the Calculation Results
The estimator will calculate three key figures for each security:
Gross Proceeds: This represents the total amount you would receive from selling the selected number of shares.
Taxes Owed: The estimator calculates the taxes you would owe based on your selected tax rates (federal, state, and any applicable net investment income tax).
Net Proceeds: This is the final amount you will receive after taxes are deducted from your gross proceeds.
At the bottom of the screen, the estimator provides a Summary View, which shows the overall impact of your selected sales. This summary includes:
Total Short-term Gain/Loss: The combined gain or loss for any short-term sales (investments held for less than a year).
Total Long-term Gain/Loss: The combined gain or loss for long-term sales (investments held for more than a year).
Overall Gain/Loss: This figure combines both short-term and long-term gains or losses, providing an overall picture of how your sales will affect your portfolio.
These results allow you to quickly assess the tax impact of your sales and adjust your strategy as needed.
Search for specific securities
If you have a large portfolio, you can use the Search Bar to locate specific securities or lots. You can search by:
Name: Type in the name of the security you want to find.
Ticker Symbol: Enter the ticker symbol (e.g., AAPL for Apple).
Acquisition Date: You can also search by the date the security was purchased.
It’s important to note that the search function only applies to the Name/Lot column. You won’t be able to search based on numerical data such as gains, losses, or holding periods.
Modify tax rates
You can adjust your tax rates at any point during your analysis. To do this, select Edit Rates at the top of the screen. This feature allows you to see how changing your federal, state, or custom tax rates will affect your estimated taxes. Adjusting tax rates is particularly useful if you’re considering different tax brackets or planning for future income changes.
Refresh security prices
The estimator allows you to refresh prices without leaving the tool. By selecting 
, you can update the market prices of your securities to reflect the most current data. This ensures that your estimated proceeds and tax liabilities are based on the latest available prices. Using this feature can be especially helpful when market conditions are volatile, and you want to ensure accuracy in your estimates.
About the Net Investment Income Tax (NIIT)
The Net Investment Income Tax (NIIT) is a 3.8% tax on certain types of investment income for individuals, estates, and trusts that exceed specific thresholds. The rate may change based on future legislation. Introduced in the Health Care and Education Reconciliation Act of 2010 to fund healthcare reform, the NIIT applies to the lesser of a taxpayer’s net investment income or the amount by which their modified adjusted gross income (MAGI) exceeds $200,000 for single filers, $250,000 for married couples filing jointly, and $125,000 for married couples filing separately. Investment income includes interest, dividends, capital gains, rental income, and certain passive business activities. It excludes wages, Social Security benefits, and distributions from qualified retirement plans. The NIIT does not apply to nonresident aliens, and careful tax planning can help manage its effect.
