Paycheck Calculator: How to Estimate Your Take-Home Pay
How to Calculate Your Paycheck: The Short Answer
A paycheck calculator turns your gross pay into take-home pay by subtracting every deduction in order. The math is identical across all 50 states—only the tax rates change. Here's the gross-to-net formula that every free tool (ADP, SmartAsset, PaycheckCity, Gusto) runs behind the scenes:
- Start with gross pay — your salary or hourly earnings for the pay period.
- Subtract pre-tax deductions — 401(k) contributions, health insurance premiums, HSA/FSA. These lower your taxable income.
- Subtract federal income tax withholding — based on the filing status and steps on your W-4.
- Subtract FICA — Social Security at 6.2% and Medicare at 1.45% (7.65% combined).
- Subtract state and local taxes — varies widely; some states charge nothing.
- Subtract post-tax deductions — Roth 401(k), wage garnishments, some benefits.
What's left is your net pay—the number on the check. If you understand this sequence, you understand every paycheck calculator on the internet. The rest of this guide breaks down each line, walks through real scenarios, and—because we build HR software for small teams—explains how to run these numbers accurately from the employer side.
Salary vs. Hourly Paycheck Calculations
The gross-to-net formula is the same for everyone, but the way you arrive at gross pay differs for salaried and hourly workers.
Salaried employees
Divide the annual salary by the number of pay periods:
- Weekly: salary ÷ 52
- Bi-weekly: salary ÷ 26
- Semi-monthly: salary ÷ 24
- Monthly: salary ÷ 12
A $65,000 salary paid bi-weekly is $2,500 gross per check ($65,000 ÷ 26). A monthly paycheck calculator would show $5,416.67 gross.
Hourly employees
Multiply the hourly rate by hours worked, then add overtime (typically 1.5× for hours over 40 in a week), plus tips, commissions, and bonuses. ADP's and Gusto's hourly paycheck calculators handle these add-ons automatically.
How much is $20 an hour per paycheck?
At $20/hour working 40 hours a week, gross weekly pay is $800. Bi-weekly gross is $1,600. After FICA (7.65% = about $122) and a rough federal withholding of $130–$160 for a single filer with no pre-tax deductions, take-home lands near $1,280–$1,320 per bi-weekly check in a no-income-tax state. Add state tax and the net drops further. These are estimates—your W-4 elections change the result. For a fast personal number, you can run the figures through our take-home pay estimator for all 50 states.
What Gets Deducted From Your Paycheck
Every deduction falls into one of four buckets. Understanding them is the difference between guessing at your take-home pay and knowing it.
Federal income tax withholding (W-4 driven)
Your employer withholds federal income tax based on the W-4 you submit. The form was redesigned in 2020—it no longer uses allowances. Instead it asks about filing status, multiple jobs, dependents, and extra withholding. Because of that change, some tools (like Maryland's Central Payroll Net Pay Calculator) offer two versions: one for pre-2020 W-4s and one for the current form. PaycheckCity even includes a W-4 assistant to help you fill it out correctly.
FICA: Social Security and Medicare
FICA is a flat payroll tax split into two parts:
- Social Security: 6.2% of wages, up to the annual wage base limit.
- Medicare: 1.45% of all wages, with an extra 0.9% on high earners.
Employers match the Social Security and base Medicare amounts dollar for dollar—a cost employees don't see on their stub but founders must budget for.
State and local income tax
Some states have no income tax; others reach past 10%. Cities like New York and several in Ohio and Pennsylvania add local income taxes on top. We cover this variation in the next section.
Pre-tax vs. post-tax deductions
Pre-tax deductions (traditional 401(k), health premiums, HSA) come out before income tax is calculated, lowering taxable wages. Post-tax deductions (Roth 401(k), garnishments) come out after. A dollar into a traditional 401(k) reduces your taxable income by a dollar—PaycheckCity's 401(k) planning feature shows exactly how a contribution change affects your net check.
Why Paycheck Amounts Differ by State
Two employees earning the same $60,000 salary can take home noticeably different amounts depending on where they work. The federal tax and FICA are identical—state and local taxes are the swing factor.
- Texas, Florida, Washington, Nevada: no state income tax, so more of the gross survives to net.
- California: progressive state income tax that climbs steeply for higher earners.
- Virginia, Wisconsin, Connecticut: moderate flat-ish or progressive state rates that trim the paycheck.
- New York City: state income tax plus a city income tax layered on top.
This is why searches like "paycheck calculator California" and "paycheck calculator Texas" exist—people want the number for their exact location. California businesses have extra costs to weigh too, like the $800 minimum franchise tax. Any paycheck calculator by state applies the same gross-to-net formula, then swaps in the correct state and local rates.
How much is $65,000 a year after taxes in NYC?
A single filer earning $65,000 in New York City faces federal income tax, FICA (7.65% ≈ $4,973), New York State income tax, and NYC local income tax. After all four, take-home typically lands in the rough range of $48,000–$50,000 per year, or about $1,850–$1,920 per bi-weekly check before any 401(k) or benefits deductions. The NYC local tax is what makes this net lower than the same salary in a no-local-tax city. Treat this as an estimate—dependents and pre-tax benefits shift it.
Worked Examples: Common Paycheck Scenarios
Here are quick, rounded walkthroughs for the questions people ask most. All figures assume a single filer with no pre-tax deductions unless noted, and are estimates for illustration.
How much tax would you pay on $1,200 a week?
- Gross: $1,200/week ($62,400 annualized)
- FICA (7.65%): about $92
- Federal withholding: roughly $120–$150
- State tax: $0 in a no-income-tax state; $40–$70 in a moderate-tax state
- Estimated net: around $960–$990/week in a no-income-tax state
$65,000 salary, bi-weekly, moderate-tax state
- Gross per check: $2,500
- FICA: about $191
- Federal + state withholding: roughly $450–$550 combined
- Estimated net: around $1,760–$1,860 per bi-weekly check
$20/hour, bi-weekly
- Gross: $1,600 (80 hours, no overtime)
- FICA: about $122
- Federal withholding: roughly $130–$160
- Estimated net: around $1,280–$1,320 in a no-income-tax state
These numbers move with your W-4, benefits, and location. Run your exact figures through a calculator—or, if you're the one cutting the checks, a payroll system that applies the current rates automatically.
Running Accurate Paychecks for a Small Team (The Employer Side)
Most paycheck calculators are built for employees checking a single number. If you're a startup founder or HR manager, your job is harder: you have to produce that correct net pay for every person, every pay period, without errors. Here's what that actually involves.
Collect and store W-4s correctly
Every employee needs a completed, current W-4 before their first paycheck. The 2020 redesign means you may have older forms and newer ones in the same file—your withholding logic has to handle both. Store them securely and update them when life events change an employee's elections. Getting this right from day one is easier with automated employee onboarding that captures clean data.
Set and track pay periods consistently
Decide whether you pay weekly, bi-weekly, semi-monthly, or monthly—and stick to it. The pay-period choice drives how you divide salaries and how often you calculate withholding. Switching mid-year creates reconciliation headaches at tax time.
Handle multi-state employees
Remote hiring means a five-person team can span three states. Each employee's paycheck must apply the correct state and local tax rules for where they work. This is where manual spreadsheets break down fast—a single wrong state rate compounds across every pay period.
Stay compliant
Beyond withholding, employers owe the matching share of FICA, must remit taxes on schedule, and have to file quarterly and year-end reports. Overtime rules, minimum wage, and pay-stub requirements vary by state, too. A calculator estimates a number; compliance is an ongoing process.
When a calculator isn't enough
A free paycheck calculator is perfect for a one-off estimate or a job offer comparison. It is not built to run recurring payroll, file taxes, track PTO, or keep employee records connected to performance and reviews. That's the gap between a calculator and an HR system. If you're weighing your options, our guide on how to choose HR software for a small business walks through the features that matter most.
HR HiFi is an AI-native HR OS built for small teams—so the same place that holds your employee records, performance reviews, and OKRs also keeps the accurate data your payroll depends on. Where standalone tools like Gusto focus on payroll and platforms like BambooHR center on records, HR HiFi ties HR workflows together so a five- or fifty-person team can scale without stitching systems by hand. Clean W-4 data, correct pay periods, and up-to-date employee records make every paycheck calculation trustworthy from the start.

Frequently Asked Questions
How do I calculate how much my paycheck will be?
Start with gross pay for the period, subtract pre-tax deductions, then federal income tax withholding, then FICA (6.2% Social Security + 1.45% Medicare), then state and local taxes, then post-tax deductions. What remains is your net pay. Any online paycheck calculator runs this exact sequence.
How much is $65,000 a year after taxes in NYC?
Expect roughly $48,000–$50,000 in take-home for a single filer, because New York City adds a local income tax on top of federal, FICA, and New York State tax. Pre-tax benefits and dependents will change the figure.
How much tax would you pay on $1,200 a week?
FICA alone is about $92. Add federal withholding of roughly $120–$150, plus state tax where it applies. In a no-income-tax state, total deductions are around $210–$240, leaving roughly $960–$990 net. These are estimates driven by your W-4.
How much is $20 an hour per paycheck?
At 40 hours a week, that's $800 gross weekly or $1,600 bi-weekly. After FICA and rough federal withholding, take-home is about $1,280–$1,320 per bi-weekly check in a no-income-tax state, before benefits and state tax.
Are online paycheck calculators accurate?
They're accurate estimates when you enter correct W-4 status, pay frequency, and deductions. They may not capture every local tax, benefit, or edge case, and tool providers state they aren't a substitute for a tax professional. For running real payroll, use a system that applies current rates and files taxes—not just a one-time estimate.
