This salary tax calculator estimates take-home pay by applying your effective tax rate and a deductions percent to gross salary. Net pay = gross − gross × tax % − gross × deductions %. For example, $80,000 with 22% tax and 8% other deductions leaves $56,000 a year.

How to use the salary tax calculator
- Enter gross pay for a year, a month or one paycheck.
- Enter your effective income tax rate as a percent.
- Enter other deductions as a percent: payroll taxes, retirement contributions and benefits.
- Read net pay, the tax amount and the deductions amount for the same period.
What formula does the salary tax calculator use?
- Tax = gross × tax percent ÷ 100
- Other deductions = gross × deductions percent ÷ 100
- Net pay = gross − tax − other deductions
The salary tax calculator applies flat percentages to the whole gross amount. Real income tax in the US, UK, India and most countries is progressive: each bracket rate applies only to the income inside that bracket. So enter your effective rate (total tax ÷ gross), not your top bracket rate.
Salary tax calculator worked example
Gross $80,000, effective tax 22%, other deductions 8%:
- Tax = 80,000 × 0.22 = $17,600
- Other deductions = 80,000 × 0.08 = $6,400
- Net = 80,000 − 17,600 − 6,400 = $56,000 a year, about $4,666.67 a month or $2,153.85 every two weeks
Net pay at different rates
Net pay on $80,000 gross:
| Tax % | Deductions 5% | Deductions 8% | Deductions 12% |
|---|---|---|---|
| 10% | $68,000 | $65,600 | $62,400 |
| 15% | $64,000 | $61,600 | $58,400 |
| 20% | $60,000 | $57,600 | $54,400 |
| 22% | $58,400 | $56,000 | $52,800 |
| 25% | $56,000 | $53,600 | $50,400 |
| 30% | $52,000 | $49,600 | $46,400 |
Net pay per paycheck
Divide annual net pay by the number of paychecks in a year. For $56,000 a year:
| Pay frequency | Paychecks a year | Net per paycheck |
|---|---|---|
| Weekly | 52 | $1,076.92 |
| Every two weeks | 26 | $2,153.85 |
| Twice a month | 24 | $2,333.33 |
| Monthly | 12 | $4,666.67 |
Biweekly pay gives 26 checks, so two months each year have three paydays. Keep the period consistent: a weekly gross needs the same percentages as an annual gross.
How to find your effective tax rate
Divide the total income tax on a recent return or pay stub by your gross pay for the same period. If last year’s federal and state income tax totaled $11,400 on $76,000 of wages, the effective rate is 15%. Your marginal (top bracket) rate is higher, which is why using it here understates take-home pay.
US payroll taxes to include
In the US, put Social Security and Medicare in the deductions percent. Employees pay 6.2% Social Security tax on wages up to the yearly wage base and 1.45% Medicare tax on all wages, plus 0.9% Additional Medicare Tax on wages above $200,000. Together that is 7.65% for most employees. Pre-tax retirement contributions and health premiums also reduce take-home pay, so add them too. Use IRS Form W-4 and the IRS Tax Withholding Estimator to set actual withholding.
Estimates for education only, not tax, legal or financial advice. Check current rules with the tax authority or a qualified adviser.
Bonuses and other supplemental pay
Bonuses often look heavily taxed on the pay stub, and the reason is withholding, not a special tax rate. In the United States, employers can withhold federal income tax on supplemental wages at a flat 22%, as described in IRS Publication 15, up to $1 million in a year. Social Security and Medicare are withheld on top of that.
Take a $5,000 bonus, which a salary tax calculator can model. Flat federal withholding is $1,100, Social Security at 6.2% is $310 and Medicare at 1.45% is $72.50, so about $3,517.50 reaches you before any state tax. If your actual marginal rate is 12%, part of the $1,100 comes back as a refund when you file. If it is 24% or 32%, you may owe more, and the salary tax calculator will show roughly how much.
A salary tax calculator works on yearly income, so the cleanest way to see the real effect of a bonus is to run it twice: once with your base salary, and once with salary plus the bonus. The difference in annual tax is what the bonus truly costs, whatever was withheld at the time. That number also tells you whether to adjust your W-4 if the bonus will push you into a higher bracket.
