TL;DR: Use our tax loss harvesting tool to see if your losses can lower your tax bill.
Ever wonder if a loss could actually reduce your taxes? Our calculator lets you check your potential savings. For example, turning a $10,000 loss into a tax cut works in taxable accounts with stocks and mutual funds. Just plug in your numbers and see your estimated savings.
This guide walks you through simple steps to turn a loss into a smart tax advantage.
Tax Loss Harvesting Calculator: Estimate Your Potential Tax Savings
This simple tool shows you how selling your investments at a loss may lower your taxes. It works only with taxable accounts holding stocks, mutual funds, and securities. Just enter the amount of your loss and your gains details to instantly see potential tax savings. For example, if you input a $10,000 loss and a $15,000 gain along with your tax rate, the tool tells you how much your taxes could drop. Remember, a $10,000 loss can really cut your tax bill if your gains are high.
The calculator is interactive and user-friendly. You type your numbers into clearly marked fields. It figures out how your losses can create current tax savings and also lower your cost basis, which might boost future gains. Note that this tool applies only to taxable accounts. It does not work with IRAs, 401(k)s, municipal bonds, 529 plans, or HSAs.
Keep the wash sale rule in mind too. If you buy back the same or a very similar security within 30 days, the loss won’t count. The tool even reminds you of this when you check your entries.

Tax Loss Harvesting Calculator Inputs and Key Variables

Start by gathering your numbers. You need four inputs: your loss amount from investments, your gains from other investments, your tax bracket choice (short-term if held under a year or long-term if held over a year), and an option to offset ordinary income when there are no gains.
For example, if you have a $10,000 loss and $15,000 in gains, decide whether those gains are taxed at the short-term rate or at the long-term rate (15% or 23.8%). This matters because your tax bill will change based on the holding period.
Key inputs include:
- Realized loss: The amount your investment fell in value.
- Realized gains: Profits from other investments that help offset the loss.
- Tax bracket: Use short-term if the asset was held for less than a year and long-term if held for more than a year.
- Ordinary-income offset: When there are no gains, you can offset up to $3,000 per year. Any remaining loss carries forward for future use.
Also, remember the wash sale rule. If you buy a similar security within 30 days, your loss won’t count. Follow these steps to record your data correctly and boost your tax savings.
Tax Loss Harvesting Calculator: Step-by-Step Usage Guide
TL;DR: Use this tool to calculate how much your losses might save you in taxes.
Begin by entering your own loss and gain amounts. For instance, if you have a $10,000 loss and $15,000 in gains, plug in those figures to see your potential tax deduction.
Next, pick the right tax rate based on how long you held the asset. For assets held over one year, use the long-term rate (15% or 23.8%). If held for less than a year, select the ordinary rate. For example, with a 24% rate, a $10,000 loss on $15,000 of gains could save you about $2,400. Fun fact: a $10,000 loss can save you over $2,000 in taxes if your rate is 24%.
Keep in mind that losses first reduce your gains. If your losses are greater than your gains, you can apply up to $3,000 to lower your ordinary income, and any extra loss carries forward.
Steps to follow:
- Enter your loss and gain amounts.
- Choose the appropriate tax bracket based on your holding period.
- Select the tax year for applying the loss.
- Review the adjusted cost basis and any remaining carryforward balance.
The calculator updates your investment’s cost basis, making it easier to plan for deductions in future years.
Tax Loss Harvesting Calculator Results: Interpreting Outputs

This calculator shows three key numbers: total tax savings, adjusted cost basis, and a carryforward balance for future tax breaks. Total tax savings tell you how much your tax bill is reduced when you use losses to offset gains or even reduce up to $3,000 of ordinary income each year. The adjusted cost basis is the new starting value for your investment, showing how selling at a loss can change your future gain calculations.
You can review these results year by year using the table below:
| Year | Loss Used | Tax Savings | Carryforward Amount |
|---|---|---|---|
| 2024 | $10,000 | $2,400 | $5,000 |
There is also a chart option that shows cumulative savings over 5 to 10 years. A higher cumulative projection means you could enjoy stronger tax-deferral benefits, highlighting the long-term advantage of harvesting losses.
Tax Loss Harvesting Calculator Scenarios: Stocks, Crypto, and Property
TL;DR: Use our calculator to adjust your tax strategy across different assets.
Imagine your stock portfolio falls by 30%. This drop can change your tax outlook by lowering future gains through a revised cost basis. For a portfolio taxed at 15% over the long term, the calculator shows how tax savings build up over time.
Now think about the crypto market. A loss in crypto can let you reduce ordinary income by up to $3,000 each year under U.S. tax rules. Even in a volatile market, this loss can boost your tax strategy by carrying forward extra losses for later use.
Finally, consider real estate. If you sell a property at a loss, you can use that loss against capital gains from another sale, both federally and at the state level. The calculator displays how adjusting your cost basis cuts taxable gains, giving you a clearer picture of long-term savings.
This flexible tool lets you experiment with various loss scenarios. Tailor your approach to match your unique portfolio mix and make smarter tax decisions.
