How to Calculate Your Take-Home Pay: Step-by-Step Guide for 2025
Learn exactly how to calculate your take-home pay from gross salary. Understand federal tax, state tax, FICA, and deductions with real examples and a free calculator.
What Is Take-Home Pay?
Take-home pay (also called "net pay") is the actual money that hits your bank account after all deductions. It's not your salary or "gross pay."
The formula:
Take-Home Pay = Gross Pay - (Taxes + Pre-Tax Deductions + Post-Tax Deductions)
Most people are surprised when they realize their advertised salary isn't what they'll actually receive.
Why Your Salary ≠ Your Take-Home Pay
Let's start with a reality check. If you're offered $100,000/year, here's what you might actually take home:
Example: $100K salary in California (Single filer)
- Gross annual salary: $100,000
- Federal income tax: ~$14,260
- California state tax: ~$4,600
- Social Security (FICA): $6,200
- Medicare: $1,450
- Take-home pay: ~$73,490/year or $6,124/month
You're losing 26.5% of your gross salary to taxes alone. And we haven't even included 401(k) contributions, health insurance, or other deductions.

Step-by-Step: Calculate Your Take-Home Pay
Step 1: Start with Gross Annual Salary
This is the number in your offer letter or employment contract.
Example: $100,000/year
Step 2: Subtract Pre-Tax Deductions
These reduce your taxable income before taxes are calculated:
Common pre-tax deductions:
- 401(k) contributions: Up to $23,000 in 2025
- Traditional IRA: Up to $7,000 in 2025
- HSA (Health Savings Account): $4,150 (individual) or $8,300 (family)
- FSA (Flexible Spending Account): Up to $3,200
- Health insurance premiums: Varies by plan
- Commuter benefits: Up to $315/month for transit
Example calculation:
- Gross salary: $100,000
- 401(k) contribution (10%): -$10,000
- HSA contribution: -$4,150
- Health insurance: -$1,200/year
- Taxable income: $84,650
Why this matters: Every dollar you contribute pre-tax saves you money on taxes. That $10,000 in 401(k) saves you ~$2,200-2,800 in taxes (22-28% bracket).
Step 3: Calculate Federal Income Tax
Federal income tax uses a progressive bracket system. You don't pay one flat rate - different portions of your income are taxed at different rates.
2025 Federal Tax Brackets (Single Filer):
- 10% on income up to $11,600
- 12% on income $11,601 to $47,150
- 22% on income $47,151 to $100,525
- 24% on income $100,526 to $191,950
- 32% on income $191,951 to $243,725
- 35% on income $243,726 to $609,350
- 37% on income over $609,350
How to calculate:
For our $84,650 taxable income example:
- First $11,600 at 10% = $1,160
- Next $35,550 ($47,150 - $11,600) at 12% = $4,266
- Remaining $37,500 ($84,650 - $47,150) at 22% = $8,250
- Total federal tax: $13,676
Pro tip: Your "marginal rate" (22%) is different from your "effective rate" (16.2%). The marginal rate is what you pay on your last dollar earned.
Step 4: Calculate State Income Tax
This varies dramatically by state.
9 states with NO income tax:
- Alaska, Florida, Nevada, New Hampshire*, South Dakota, Tennessee, Texas, Washington*, Wyoming
- (*NH taxes interest/dividends; WA has capital gains tax)
States with FLAT tax rates:
- Colorado: 4.40%
- Illinois: 4.95%
- Indiana: 3.05%
- Michigan: 4.25%
- And others...
States with PROGRESSIVE rates (like California):
- California: 1% to 13.3%
- New York: 4% to 10.9%
- Hawaii: 1.4% to 11%
Example for California (progressive): On $84,650 taxable income:
- State tax: ~$4,200
Example for Texas (no income tax):
- State tax: $0
The difference: Texas saves you $4,200/year in this example! See your state →
Step 5: Calculate FICA Taxes
FICA = Social Security + Medicare. Everyone pays these, regardless of state.
2025 FICA Rates:
- Social Security: 6.2% on first $168,600 of income
- Medicare: 1.45% on all income
- Additional Medicare Tax: 0.9% on income over $200,000 (single) or $250,000 (married)
Example on $100K gross:
- Social Security: $100,000 × 6.2% = $6,200
- Medicare: $100,000 × 1.45% = $1,450
- Total FICA: $7,650
Note: If you're self-employed, you pay DOUBLE (employer + employee portion) = 15.3% total.
Step 6: Calculate Local/City Taxes (If Applicable)
Some cities and counties charge income tax:
Cities with local income tax:
- New York City: 3.078% to 3.876%
- Philadelphia, PA: 3.75%
- Detroit, MI: 2.4%
- Cleveland, OH: 2.5%
- Baltimore, MD: 3.2%
- And 14+ other cities
Example: NYC resident On $100K salary, add ~$3,800 in city tax.
Step 7: Subtract Post-Tax Deductions
These come out after taxes are calculated:
Common post-tax deductions:
- Roth 401(k) contributions
- Roth IRA contributions (done outside payroll usually)
- Disability insurance premiums
- Life insurance
- Union dues
- Parking fees (if not pre-tax)
- Wage garnishments
Example:
- Additional life insurance: $50/month = $600/year
- Parking: $100/month = $1,200/year
- Total post-tax deductions: $1,800/year
Step 8: Calculate Final Take-Home Pay
Putting it all together:
Starting point: $100,000 gross salary (California, single filer)
Pre-tax deductions:
- 401(k): -$10,000
- HSA: -$4,150
- Health insurance: -$1,200
- Taxable income: $84,650
Taxes:
- Federal income tax: -$13,676
- California state tax: -$4,200
- Social Security: -$6,200
- Medicare: -$1,450
- Total taxes: -$25,526
Post-tax deductions:
- Life insurance: -$600
- Parking: -$1,200
- Total post-tax: -$1,800
Final calculation: $100,000 - $10,000 - $4,150 - $1,200 - $25,526 - $1,800 = $57,324/year
Monthly take-home: $57,324 ÷ 12 = $4,777/month
Your $100K salary becomes $4,777/month in reality.
Real Examples by State
Same $100K salary, different states:
Example 1: California (High Tax)
- Federal + FICA: -$21,326
- California state: -$4,200
- Pre-tax deductions: -$15,350
- Take-home: ~$59,124/year ($4,927/month)
Example 2: Texas (No State Tax)
- Federal + FICA: -$21,326
- State tax: $0
- Pre-tax deductions: -$15,350
- Take-home: ~$63,324/year ($5,277/month)
Example 3: New York (High Tax + NYC)
- Federal + FICA: -$21,326
- New York state: -$4,800
- NYC city tax: -$3,800
- Pre-tax deductions: -$15,350
- Take-home: ~$54,724/year ($4,560/month)
The difference: Texas vs NYC = $717/month more ($8,600/year) on the same $100K salary!
Common Mistakes People Make
Mistake 1: Forgetting About Medicare
People remember to account for Social Security (6.2%) but forget Medicare (1.45%). That's an extra $1,450 on $100K.
Mistake 2: Using Old Tax Brackets
Tax brackets change annually. Always use current year rates (2025 in this example).
Mistake 3: Not Accounting for Local Taxes
If you work in NYC, Philadelphia, Detroit, or other cities with local tax, you're losing another 2-4% you might not expect.
Mistake 4: Confusing Marginal vs Effective Tax Rate
Your top bracket (marginal rate) isn't what you pay on all your income. On $100K, you might be in the 22% bracket, but your effective rate is only ~16%.
Mistake 5: Ignoring Pre-Tax Savings Benefits
Every $1 you put in 401(k)/HSA saves you $0.22-0.37 in taxes (depending on your bracket). It's not just savings - it's instant ROI.
How to Increase Your Take-Home Pay
Strategy 1: Maximize Pre-Tax Contributions
- Max out 401(k): $23,000 in 2025
- Use HSA if eligible: $4,150 (individual)
- Contribute to FSA: $3,200 for healthcare
Tax savings on $100K salary:
- Contributing $27,150 to pre-tax accounts
- Saves you ~$5,974 in federal taxes (22% bracket)
- Plus state tax savings of ~$1,357 (CA)
- Total tax reduction: $7,331
You're paying $7,331 less in taxes while saving $27,150 for retirement/healthcare!
Strategy 2: Move to a Lower-Tax State
We showed this above: Texas saves you $4,200/year vs California.
Over 10 years, that's $42,000 more in your pocket (same job, same salary).
Strategy 3: Optimize Your Filing Status
- Married Filing Jointly: Lower tax rates than single
- Head of Household: Better than single if you qualify
- Adjust W-4 withholdings: Get more per paycheck (but be careful of tax bill at year-end)
Strategy 4: Increase Your Gross Salary
Obviously, but how much do you need to increase to hit your take-home goal?
Example: You want $6,000/month take-home (California)
- After taxes (~27%), you need $8,219 gross/month
- Annual salary needed: ~$98,630
Use this formula:
Desired Take-Home ÷ (1 - Tax Rate %) = Required Gross
Strategy 5: Negotiate Benefits, Not Just Salary
Sometimes benefits are worth more than salary increases:
Example:
- $5,000 salary increase = ~$3,650 after taxes
- $5,000 in employer 401(k) match = full $5,000 value (no taxes now)
- $3,000 in HSA employer contribution = full $3,000 + tax savings
