Bonus Calculator

Estimate taxes withheld and net take-home pay on a bonus.

These calculators are for informational purposes only and do not constitute financial, legal, or tax advice.

These figures are estimates only, based on simplified, configurable tax assumptions, and are not tax advice. Actual withholding and net pay depend on your complete tax situation — consult a qualified tax professional or your payroll provider.


Bonus Calculator
Estimate how much of your bonus you’ll actually take home after federal, state, and payroll tax withholding.

Quick Answer
This Bonus Calculator estimates how much of a bonus payment goes to withholding and how much you’d actually take home. Enter your gross bonus amount and an optional state withholding rate, and it estimates federal withholding (using the IRS supplemental wage rate), Social Security, Medicare, and your estimated net bonus – all in USD ($). Whether it’s an annual bonus, a year-end bonus, a signing bonus, or a performance payout, the withholding math works the same way.
Getting a bonus is good news – until the payment lands and it’s noticeably smaller than you expected. This Bonus Calculator helps you see why, by estimating the withholding on a bonus payment and showing your likely take-home amount before it hits your bank account.
It works whether you’re estimating an annual bonus, a year-end bonus, a signing bonus, a performance bonus, or a commission-related payout – the federal and payroll tax withholding mechanics are the same regardless of what the bonus is called.
What Is a Bonus Calculator?
A Bonus Calculator estimates what happens to a bonus payment between the moment it’s announced and the moment it lands in your bank account. This tool specifically focuses on the withholding side: starting from your gross bonus amount, it estimates federal withholding, Social Security, Medicare, and (if you enter a rate) state withholding, then shows your estimated net bonus – the amount you’d actually receive.
It’s useful for anyone who’s been told a bonus number and wants a realistic sense of their actual take-home amount, rather than being surprised by the paycheck.
How to Use the Bonus Calculator
The calculator uses two inputs:
Input What to Enter
Bonus Amount The gross dollar amount of your bonus before any taxes or deductions – for example, $5,000.
State Withholding Rate (optional) Your state’s withholding rate on supplemental wages, if applicable – enter 0 if you’re in a state with no income tax.
Note: This calculator estimates withholding on a bonus amount you already know. It does not calculate a bonus FROM your salary and a bonus percentage – see the “Bonus Calculator Formula” section below for how to work out a percentage-based bonus amount manually before entering it here.
Once you enter your bonus amount, the calculator applies the IRS federal supplemental wage withholding rate, plus Social Security and Medicare, and your optional state rate, to estimate your net (take-home) bonus.
Bonus Calculator Formula
If your bonus is set as a percentage of your salary, here’s how to work out the dollar amount before checking its withholding:
Percentage-Based Bonus
Bonus = Annual Salary × Bonus Percentage
Total Compensation
Total Compensation = Annual Salary + Bonus
Example 1: Annual salary = $80,000, bonus percentage = 10%
Bonus = $80,000 × 10% = $8,000
Total compensation = $80,000 + $8,000 = $88,000
Example 2: Annual salary = $95,000, bonus percentage = 12%
Bonus = $95,000 × 12% = $11,400
Total compensation = $95,000 + $11,400 = $106,400
These are gross figures – before any taxes or withholding. Once you know your gross bonus dollar amount, you can enter it into the calculator above to estimate what you’d actually take home.
Bonus Percentage Examples
For a $75,000 annual salary, here’s how different bonus percentages translate into dollar amounts and total compensation:
Bonus Percentage Bonus Amount Total Compensation
5% $3,750 $78,750
10% $7,500 $82,500
15% $11,250 $86,250
20% $15,000 $90,000
25% $18,750 $93,750
30% $22,500 $97,500

How Are Employee Bonuses Calculated?
Employers use several common approaches, and actual bonus structures vary widely by company:
• Percentage of Salary – the bonus is calculated as a set percentage of annual salary (e.g., 10% of base pay).
• Fixed Bonus – the employee receives a predetermined dollar amount, regardless of salary.
• Performance-Based Bonus – the amount depends on individual, team, or company performance against goals.
• Target Bonus – the employee has a stated target percentage that can increase or decrease based on how performance measures up.
• Discretionary Bonus – the employer decides the amount based on business results or individual circumstances, without a fixed formula.
How Are Bonuses Taxed in the US?
Bonuses are considered “supplemental wages” by the IRS, and employers commonly withhold federal tax on them using a flat supplemental wage rate (22% for bonuses under $1 million, as of recent IRS guidance) rather than your regular paycheck’s withholding method.
On top of federal withholding, a bonus is also typically subject to:
• Social Security tax – 6.2% of the bonus, up to the annual Social Security wage base
• Medicare tax – 1.45% of the bonus, with no wage base cap
• State and local income tax – where applicable, at rates that vary by location
Withholding is not the same as your final tax liability. The 22% federal supplemental rate (or your employer’s chosen method) is simply how much gets held back from the bonus paycheck – your actual tax owed on that income is determined when you file your tax return, based on your total annual income, deductions, and credits. If too much was withheld, you’d get the difference back as part of your refund; if too little was withheld, you could owe more at tax time.
Why Is My Bonus Taxed So Much?
It usually comes down to the withholding method, not a higher actual tax rate. A 22% flat federal withholding rate, plus Social Security, Medicare, and state tax, can add up to 30% or more withheld from a bonus check, which can feel like a lot compared to a regular paycheck.
But withholding is just money set aside in advance – it isn’t necessarily your final tax rate on that income. Many people who have “too much” withheld from a bonus see that reconciled through a larger refund when they file their taxes. Bonuses aren’t automatically taxed at a higher final rate than regular income; they’re just often withheld differently upfront.
Gross Bonus vs. Net Bonus
Term Meaning
Gross Bonus The bonus amount before taxes and other deductions – the number your employer announces
Net Bonus The amount you actually receive after applicable withholding
Using this calculator’s own example: a $5,000 gross bonus, with a 5% state withholding rate and the default 22% federal supplemental rate, results in roughly $1,732.50 in total withholding (federal, state, Social Security, and Medicare combined) – leaving an estimated net bonus of about $3,267.50.
Bonus vs. Regular Salary
Feature Salary Bonus
Payment Structure Paid on a regular, recurring schedule Often paid once or periodically (annually, quarterly, etc.)
Predictability Generally consistent and known in advance Can vary year to year based on performance or company results
Performance-Related Typically not tied to short-term performance Often tied to individual, team, or company performance
Tax Withholding Withheld using regular payroll tax tables Often withheld using the flat IRS supplemental wage rate
Guaranteed Generally guaranteed under the employment agreement Often discretionary or performance-contingent, depending on the agreement
These are general patterns – actual terms always depend on your specific employment agreement and employer policies.
What Is a Good Bonus Percentage?
There’s no single bonus percentage that applies universally – it varies significantly based on industry, job level, company policy, individual and company performance, compensation structure, location, seniority, and the specific terms of your employment agreement.
Some roles are structured with a modest target bonus in the single digits as a percentage of salary, while others – particularly sales, executive, or finance-industry roles – may have target bonuses well into double digits or structured very differently (such as commission-based pay). Rather than comparing your bonus percentage to a generic benchmark, it’s generally more useful to understand how your specific employer structures bonuses and what’s considered typical within your role and industry.
Bonus Calculation Examples
Illustrative examples only. Figures are gross, before taxes, unless otherwise noted.
Example 1 – 10% Annual Bonus
Salary: $60,000. Bonus = $60,000 × 10% = $6,000. Total compensation = $60,000 + $6,000 = $66,000.
Example 2 – 15% Performance Bonus
Salary: $100,000. Bonus = $100,000 × 15% = $15,000. Total compensation = $100,000 + $15,000 = $115,000.
Example 3 – Fixed Bonus
Salary: $85,000. Fixed bonus: $5,000. Total compensation = $85,000 + $5,000 = $90,000.
Example 4 – Target Bonus
Salary: $120,000. Target bonus: 20%. Bonus = $120,000 × 20% = $24,000. Total compensation = $120,000 + $24,000 = $144,000 (assuming the full target bonus is paid – actual payout may be higher or lower depending on performance against the target).
Bonus Calculator vs. Salary Calculator
Use a Bonus Calculator when you want to understand withholding and take-home pay on a bonus payment specifically. Use a salary or paycheck calculator when you want to estimate your regular, ongoing take-home pay from your base salary. The two serve different purposes: one focuses on a one-time or periodic bonus payment, while the other focuses on your recurring paycheck.
Frequently Asked Questions
How do I calculate my bonus?
If your bonus is a percentage of salary, multiply your annual salary by the bonus percentage. If it’s a fixed amount, it’s simply that dollar figure. Once you know the gross amount, you can use the Bonus Calculator above to estimate withholding and your net take-home amount.
How do I calculate a bonus percentage?
Divide the bonus dollar amount by the annual salary, then multiply by 100. For example, a $6,000 bonus on a $60,000 salary is a 10% bonus.
What is a 10% bonus on $50,000?
$50,000 x 10% = $5,000 gross bonus, before taxes and withholding.
Are bonuses taxed differently from salary?
Bonuses are often withheld differently – commonly at a flat federal supplemental wage rate (22% for amounts under $1 million) rather than your regular paycheck’s withholding tables. This affects withholding, not necessarily your final tax rate on that income.
Why is my bonus paycheck smaller than expected?
Bonus payments combine federal supplemental withholding, Social Security, Medicare, and often state tax, which together can withhold 30% or more of the gross amount – larger than many people expect compared to a regular paycheck.
What is the difference between gross and net bonus?
Gross bonus is the full amount before taxes and deductions. Net bonus is what you actually receive after withholding – the gross amount minus federal, state, Social Security, and Medicare withholding.
Are bonuses subject to Social Security and Medicare taxes?
Yes. Bonuses are generally subject to the same 6.2% Social Security tax (up to the annual wage base) and 1.45% Medicare tax that apply to regular wages.
Can I calculate my bonus from my salary?
Yes, if your bonus is structured as a percentage of salary: multiply your annual salary by the bonus percentage to get the gross bonus amount.
How does a performance bonus work?
A performance bonus ties the payout to individual, team, or company results against specific goals. The exact structure, target percentage, and payout conditions vary by employer and role.
Does a bonus increase my total compensation?
Yes. Total compensation generally includes your base salary plus any bonus received, along with other benefits your employer may count toward total compensation.
Whether you’re estimating a percentage-based bonus from your salary or checking how much of an already-known bonus amount you’ll actually take home, this Bonus Calculator can help you plan around the real number rather than the gross figure alone. Try entering your own bonus amount above to see an estimated breakdown of withholding and net pay.
