Restricted Stock Units (RSUs) are one of the most common forms of equity compensation in the U.S., especially in the tech and finance industries. While they can grow into a significant wealth-building tool, the complexities of taxes, vesting schedules, and market volatility can make financial planning daunting. Many employees are left wondering: "What will my RSUs actually be worth after taxes?" and "Should I sell immediately or hold for the long term?"
Our comprehensive RSU Future Gain & Tax Calculator is designed to demystify this process. It helps you project your future vesting value, estimate your total tax liability, and understand your net after-tax gains, empowering you to make smart, strategic financial decisions about your equity compensation.
Restricted Stock Units (RSUs)
What Are RSUs?
Restricted Stock Units (RSUs) are a promise from an employer to grant an employee a set number of shares of company stock at a future date, once certain conditions (primarily time-based vesting) are met. Unlike stock options, which give you the *right* to buy shares at a fixed price, RSUs are simply shares granted to you for free upon vesting. You don't own them immediately, and there's no purchase price involved.
How RSUs Work
The lifecycle of an RSU follows a predictable path:
- Grant Date: Your company awards you a specific number of RSUs.
- Vesting Period: You must remain employed for a specific period (typically 3-4 years) to earn the right to the shares.
- Vesting Date(s): On each vesting date, a portion of your RSUs "vests," meaning the restrictions lapse, and they convert into actual shares of company stock deposited into your brokerage account.
- Post-Vesting: Once you own the shares, you can choose to either sell them immediately or hold them as an investment.
RSU Vesting Schedules
Understanding your vesting schedule is critical for accurate planning. The two most common types are:
- Cliff Vesting: A one-time, large vesting event after an initial period, usually one year. For example, in a 4-year schedule with a 1-year cliff, 25% of your total grant vests after the first year.
- Graded Vesting: Shares vest incrementally over time. After the initial cliff, vesting might occur monthly or quarterly. A common pattern is "4-year vesting with a 1-year cliff, then quarterly thereafter." This means you get 25% after year one, and the remaining 75% vests in equal increments each quarter for the next three years.
RSU vs Stock Options vs ESPP
It's easy to confuse RSUs with other forms of equity compensation. Here’s a quick comparison:
| Feature |
Restricted Stock Units (RSUs) |
Stock Options (NSOs/ISOs) |
Employee Stock Purchase Plan (ESPP) |
| What you get |
Shares granted for free upon vesting |
The right to buy shares at a fixed price (strike price) |
The right to buy shares at a discount (up to 15%) |
| Cost to Acquire |
None |
You must pay the strike price to exercise |
You use payroll deductions to purchase shares |
| Taxation Point |
At vesting (as ordinary income) |
At exercise (and sale for NSOs); complex rules for ISOs |
At purchase and sale; discount is taxed as income |
| Downside Risk |
Low. Value can't go below zero. |
High. Options can become worthless if stock price falls below strike price. |
Low. You start with an instant discount. |
RSUs are generally considered lower-risk than options because they always have some tangible value unless the company stock becomes worthless.
The Financial Impact of RSUs
The Value of RSUs Over Time
The value of your RSU grant is directly tied to your company's stock price. If the stock price increases between the grant date and the vesting date, the value of your shares increases. This potential for growth is a key benefit. However, it's a double-edged sword; if the stock price declines, so does the value of your unvested and vested shares. Market volatility means your RSU future value is a projection, not a guarantee.
Taxes on RSUs
Taxes are the single biggest factor that reduces the value of your RSUs. In the U.S., RSUs are subject to a two-step tax process:
- Vesting Tax (Ordinary Income): On the day your RSUs vest, the fair market value of the shares is treated as supplemental income by the IRS. This amount is added to your W-2 and taxed at your federal, state, and FICA (Social Security & Medicare) income tax rates.
- Sale Tax (Capital Gains): If you decide to hold the shares after vesting, any subsequent change in value is subject to capital gains tax when you sell.
- Short-Term Capital Gains: If you sell within one year of the vesting date, the profit is taxed at your ordinary income tax rate.
- Long-Term Capital Gains: If you hold the shares for more than one year after vesting, the profit is taxed at a lower, preferential long-term capital gains rate.
Example: How Taxes Affect Net RSU Value
Let's say you have 1,000 RSUs vesting when the stock price is $100, for a total value of $100,000.
- At Vesting: The entire $100,000 is reported as income. Your employer will likely withhold shares to cover taxes (e.g., sell 300 shares to cover an estimated ~30% tax, leaving you with 700 shares).
- Your True Tax Liability: If your combined marginal tax rate (federal, state, FICA) is 40%, your actual tax due is $40,000. If withholding only covered $30,000, you may owe an additional $10,000 when you file your tax return.
- At Sale: If you immediately sell your 700 net shares for $100 each, you get $70,000 cash. If you hold and the price rises to $120, selling would trigger a capital gains tax on the $20 per share gain ($14,000 total).
This complexity is precisely why an RSU tax calculator USA is essential for accurate planning.
Common RSU Tax Mistakes
- Assuming Withholding Covers Everything: The flat 22% federal supplemental withholding rate may be lower than your top marginal tax bracket, leading to a surprise tax bill.
- Ignoring State Taxes: Employees in high-tax states like California (13.3%) or New York (up to 10.9%) can see nearly half their RSU value go to taxes if they don't plan accordingly.
- Holding Too Much Company Stock: For emotional reasons or a belief the stock will only go up, employees fail to diversify, exposing them to unnecessary risk.
RSU Future Gain & Tax Calculator Overview
Why Use an RSU Calculator?
Manually projecting the future value and tax impact of your RSUs across multiple vesting dates is a complex task involving compound growth and tiered tax rates. An RSU future gain calculator automates this math, providing you with a clear, data-driven picture of your potential net worth. It helps you answer critical questions like, "What will my net income be from my next vesting event?" and "How much more could I earn by holding shares for long-term gains?"
Key Features of This Calculator
Our tool is built specifically for U.S. employees and incorporates all the necessary variables:
- Grant & Vesting Details: Input your grant date, total RSUs, and detailed vesting schedule (including cliffs).
- Comprehensive Tax Inputs: Account for your specific federal, state, and FICA tax rates, as well as long-term capital gains rates.
- Realistic Growth Assumptions: Apply an expected annual stock price growth rate to see how your RSU value could appreciate.
- Strategic Modeling: Toggle between an "immediate sale" strategy and a "hold for long-term gains" strategy to compare outcomes.
How the RSU Calculator Works
Restricted Stock Units (RSUs) are a valuable part of modern compensation in the U.S.
This calculator helps you estimate your future RSU value, taxes at vesting,
long-term gains, and net cash after all deductions.
Grant & Vesting Details
This section defines how and when your RSUs are awarded and converted into shares.
1. Grant Date
- Definition: The date when your company granted you the RSUs.
- Purpose: Starting point for vesting schedule and projections.
- Example: January 1, 2024, with a 12-month cliff → first vesting on January 1, 2025.
2. Total RSU Granted

Output Section
Based on your inputs, the calculator provides the following projections:
- Future Value at Vesting: Total pre-tax value of all RSUs when fully vested.
- Tax at Vesting: Total income taxes due on vested shares.
- Net Shares Received: Shares you actually keep after withholding.
- Future Sale Value: Estimated value if shares are held and sold later.
- Capital Gains Tax: Additional tax due when selling held shares.
- Net Cash After All Taxes: Actual take-home profit from RSUs.
Example Scenarios
Example 1: Employee with Quarterly Vesting
Scenario: A software engineer in Texas (0% state income tax) is granted 1,000 RSUs. The vesting schedule is 4 years with a 1-year cliff, then quarterly. The current stock price is $50, with an expected annual growth rate of 10%. They plan to sell all shares immediately upon vesting. Their federal tax rate is 32%.
Calculator Insight: The tool would project the total value at each vesting date, calculate the income tax due (only federal and FICA in this case), and show the engineer that their net after-tax cash from the grant will be significantly less than the headline $50,000 value, helping them plan their budget and investments.
Example 2: Holding RSUs for Long-Term Gains
Scenario: Using the same grant as above, but the employee decides to hold all net shares for more than one year after each vesting event.
Calculator Insight: The model would show a higher potential future sale value due to continued growth but also factor in the long-term capital gains tax upon the eventual sale. The user can clearly see the trade-off between the immediate cash from selling and the potential for higher, but riskier, returns from holding.
Example 3: State Tax Comparison
Scenario: Compare two employees with identical RSU grants: one in California (13.3% state tax) and one in Washington (0% state tax).
Calculator Insight: The RSU after tax value for the California employee would be dramatically lower. This stark comparison is vital for financial planning and can even influence decisions about remote work or relocation.
How to Maximize Your RSU Value
- Understand Your Vesting Dates: Mark your calendar for every vesting event. This allows you to plan for tax payments and decide on a sell/hold strategy in advance, not under pressure.
- Plan for Taxes in Advance: Use our RSU tax calculator to estimate your true tax liability. If your employer's withholding is insufficient, set aside money or make estimated tax payments to avoid penalties.
- Diversify After Vesting: Your income (salary) is already tied to the company's health. Holding a large amount of company stock concentrates your risk. A common strategy is to sell a majority of vested shares immediately to diversify your investments.
- Use the Long-Term Capital Gains Advantage: If you believe in your company's long-term prospects and can afford the risk, holding shares for over a year after vesting can qualify you for lower tax rates on the growth. Weigh the potential tax savings against the risk of the stock price falling.
- Integrate RSUs with Your Overall Financial Plan: Don't treat RSUs in isolation. Consider using the cash from sold RSUs to max out your 401(k), IRA, or pay down high-interest debt as part of a holistic financial strategy.
Pros and Cons of RSUs
✅ Advantages of RSUs
- Lower Risk: Unlike options, RSUs always have value unless the stock goes to zero.
- Simple & Straightforward: No need to decide when to exercise or come up with cash to buy shares.
- Powerful Retention Tool: The multi-year vesting schedule incentivizes you to stay with the company.
- Direct Alignment with Shareholders: Your financial success is directly tied to the company's performance.
❌ Disadvantages of RSUs
- Tax Timing is Not Flexible: You are taxed at vesting, regardless of the stock price, which can be a burden if the stock is highly volatile.
- Concentration Risk: It's easy to end up with a portfolio over-weighted in a single stock, which is inherently risky.
- Value is Tied to Company Performance: Your compensation can be negatively impacted by market downturns or company-specific issues.
- No Voting Rights/Dividends Until Vested: You don't get the benefits of stock ownership until the shares are officially yours.
RSU Tax Rules in the U.S.
Federal Taxation
The entire value of the shares on the day they vest is considered ordinary income and is subject to federal income tax. It is reported on your Form W-2 by your employer.
State Taxation
You must also pay state income tax on the vested value based on your state of residence on the vesting date. This is a crucial point for remote workers or those who move between states. Moving from a high-tax state (e.g., CA) to a no-tax state (e.g., TX, FL, WA) *before* a major vesting event can save you a substantial amount of money.
FICA & Medicare
For most employees, the value of vested RSUs is subject to Social Security and Medicare taxes (FICA) in the same way your regular salary is.
Capital Gains Tax
This is a separate tax on the growth of the stock after it vests. The rate depends on your holding period:
- Short-Term: Held for one year or less. Taxed at your ordinary income tax rate.
- Long-Term: Held for more than one year. Taxed at preferential rates (0%, 15%, or 20% for most people).
Common Questions About RSUs (FAQ)
Do I pay taxes when RSUs are granted?
No. Taxes are not due when RSUs are granted. The taxable event occurs when the RSUs vest and you officially take ownership of the shares.
How do I calculate how much tax will be withheld?
Most companies use a flat 22% for federal supplemental withholding and the applicable state rate. However, this is just an estimate. Your actual tax liability will depend on your total annual income and tax bracket. Our RSU vesting schedule calculator helps you find your true liability.
What happens if I leave my company before vesting?
Any RSUs that have not yet vested are typically forfeited and returned to the company. Always check your specific equity agreement for details.
Is it better to sell RSUs immediately or hold them?
There's no one-size-fits-all answer. Selling immediately locks in your gain, pays taxes, and allows you to diversify risk. Holding offers the potential for higher returns and lower capital gains taxes but carries the risk of the stock price falling. This is the core decision our calculator helps you model.
Can RSUs lose value?
Yes, absolutely. The value of your vested shares fluctuates with the company's stock price. If the price drops after you vest, the value of your holdings decreases.
Are RSUs part of my W-2 income?
Yes. The value of the shares on the vesting date is included in your W-2 as part of your taxable income for that year.
Do RSUs affect AMT (Alternative Minimum Tax)?
No. Unlike Incentive Stock Options (ISOs), RSUs are not a trigger for the Alternative Minimum Tax. This simplifies tax planning significantly.
How do I report RSU sales on my tax return?
You will receive a Form 1099-B from your brokerage detailing the sale. You must report this on your tax return (Schedule D) to calculate your capital gain or loss. The cost basis for the shares is the value on the vesting date, which is already reported on your W-2.
