Take-Home Pay Calculator Guide — US & UK 2026
Your gross salary is the number on your contract or offer letter. Your take-home pay — also called net pay — is the amount that actually lands in your bank account after taxes, National Insurance (in the UK), Social Security and Medicare (in the US), and any other deductions have been removed. For most people in middle-income brackets, take-home pay is 65–80% of gross salary. Understanding what reduces it, and why, is one of the most useful pieces of financial knowledge you can have.
How US Take-Home Pay Is Calculated in 2026
American paychecks go through several layers of deduction before you see the final number. Understanding each layer helps you plan more effectively — and spot errors on your pay stub.
Step 1 — Start with Gross Pay
Your gross pay is your full earnings for the pay period before any deductions. For salaried employees this is simply annual salary ÷ pay periods. For hourly workers it is hourly rate × hours worked in the period.
Step 2 — Subtract Pre-Tax Deductions
Pre-tax deductions reduce your taxable income before federal (and often state) taxes are calculated. Common examples include 401(k) or 403(b) retirement contributions, health insurance premiums paid through your employer, HSA (Health Savings Account) contributions, and FSA (Flexible Spending Account) contributions. Maximising pre-tax deductions is one of the most effective ways to reduce your tax bill legally — every dollar contributed pre-tax reduces your taxable income by a dollar.
Step 3 — Apply the Standard Deduction and Federal Tax Brackets
After pre-tax deductions, you subtract the standard deduction for your filing status. For 2026, the estimated standard deduction is:
- Single / Married Filing Separately: $16,100
- Married Filing Jointly: $32,200
- Head of Household: $24,150
The remaining taxable income is taxed at progressive federal rates. The 2026 brackets run from 10% on the lowest income tier up to 37% on income above roughly $640,000 (single). Because the US tax system is progressive, only income within each bracket is taxed at that bracket's rate — your entire income is never taxed at your "top" marginal rate.
Step 4 — FICA Taxes (Social Security + Medicare)
FICA (Federal Insurance Contributions Act) taxes fund Social Security and Medicare:
- Social Security: 6.2% of wages up to the 2026 wage base of $184,500.
- Medicare: 1.45% of all wages (no cap).
- Additional Medicare: 0.9% on wages above $200,000 (single), $250,000 (MFJ), or $125,000 (MFS).
Note: your employer also pays a matching 6.2% Social Security and 1.45% Medicare contribution on your behalf — this does not come out of your paycheck but is part of the total employment cost your employer pays.
Step 5 — State Income Tax
43 states levy a state income tax on wages. Rates vary enormously — from a flat 3.07% in Pennsylvania to progressive top rates above 13% in California. Eight states have no state income tax at all: Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington and Wyoming. This calculator uses a simple flat-rate estimate for states; for exact state withholding, consult your state's withholding tables or a payroll service.
Step 6 — Post-Tax Deductions
After taxes come post-tax deductions: Roth 401(k) contributions, union dues, garnishments, and any other deductions taken from your after-tax pay. These reduce your take-home cash but do not reduce your tax liability.
Gross annual: $75,000 | Pre-tax deductions (401k): $6,000
Federal taxable income: $75,000 − $6,000 − $16,100 = $52,900
Federal income tax: ~$6,600 | FICA: ~$5,738
NY state tax (est. ~6%): ~$4,140
Estimated net annual: ~$52,522 (~$2,020 bi-weekly)
How UK Take-Home Pay Is Calculated in 2026
UK take-home pay is calculated under the PAYE (Pay As You Earn) system, which deducts Income Tax and National Insurance directly from each payslip through your employer's payroll.
Personal Allowance (2025/26)
The first £12,570 of earnings is tax-free — this is the Personal Allowance. It begins to taper away for earners above £100,000 (losing £1 of allowance for every £2 of income above that threshold) and disappears entirely at £125,140.
Income Tax Bands (England, Wales and Northern Ireland)
- 20% Basic Rate: £12,571–£50,270
- 40% Higher Rate: £50,271–£125,140
- 45% Additional Rate: Above £125,140
Scottish Income Tax (2025/26 estimate)
Scotland sets its own income tax rates. There are currently six bands ranging from 19% (Starter Rate) to 48% (Top Rate), with the Intermediate Rate of 21% applying between roughly £14,877 and £26,561. Scottish taxpayers with the same salary as English taxpayers typically pay slightly more income tax on earnings in the intermediate bands.
National Insurance (Employee Contributions)
Employee NI in 2025/26:
- 8% on earnings between the Primary Threshold (£12,570) and the Upper Earnings Limit (£50,270).
- 2% on earnings above £50,270.
This means most basic-rate taxpayers pay a combined marginal rate of 28% (20% income tax + 8% NI) on earnings in the basic rate band — not the 20% that is often quoted in casual conversation.
Personal Allowance: £12,570 (tax-free)
Income Tax: 20% × (£45,000 − £12,570) = 20% × £32,430 = £6,486
National Insurance: 8% × (£45,000 − £12,570) = £2,594
Total deductions: £9,080
Estimated net annual: £35,920 (~£2,993/month)
Pre-Tax vs Post-Tax Deductions — Why It Matters
Not all deductions are equal. Pre-tax deductions (in the US: traditional 401k, HSA, FSA, employer health insurance; in the UK: salary sacrifice pension contributions) reduce your taxable income before taxes are applied. This means you save tax on every pound or dollar contributed. Post-tax deductions (Roth contributions, union dues) come out after tax and don't change your tax bill.
If you have the option to make pension or retirement contributions pre-tax, it is almost always advantageous to do so — especially at higher marginal rates where the tax saving is largest. Use the pre-tax deductions field in this calculator to model how increasing your pre-tax contributions affects your net paycheck and your annual tax bill.
Pay Frequency — How It Affects Your Paycheck
Your annual salary is the same regardless of how often you are paid, but the tax withheld per paycheck varies with frequency. US biweekly employees get 26 paychecks per year; semimonthly employees get 24. The annual tax liability is the same, but the per-paycheck withholding differs. In some years, biweekly-paid employees receive 27 paychecks instead of 26 — a "bonus paycheck" month — which some payroll systems handle by withholding slightly more throughout the year.
UK employees are almost universally paid monthly (12 paychecks per year), which simplifies the PAYE calculation considerably.
How to Maximise Your Take-Home Pay
- Max out pre-tax retirement contributions. In the US, the 2026 401(k) employee contribution limit is estimated at $23,500 ($31,000 if age 50+). Every dollar contributed reduces federal and state taxable income.
- Use an HSA if you have a qualifying high-deductible health plan. HSA contributions are triple tax-advantaged: pre-tax going in, tax-free growth, and tax-free withdrawals for qualified medical expenses.
- Check your W-4 (US). Claiming the correct withholding allowances means you neither owe a large amount at filing nor overpay throughout the year.
- UK: consider salary sacrifice. Employer-arranged salary sacrifice pension contributions reduce both income tax and National Insurance, saving more than a personal pension contribution would.
- UK: check your tax code. An incorrect HMRC tax code can cause significant under or over-deduction of income tax. Common errors include carrying forward emergency codes or not claiming Marriage Allowance.

Frequently Asked Questions
1) Is this take-home pay calculator accurate for 2026?
It is a close estimate using 2026 tax brackets, standard deductions and FICA rates. Actual paychecks can differ due to local income taxes (US), exact benefit plan types, tax credits, bonus withholding rules and employer-specific configurations. Use this for planning; verify with your pay stub or a payroll professional.
2) What should I enter as gross pay?
Enter your gross pay for the selected frequency. If you are paid bi-weekly, enter your gross bi-weekly amount (not your annual salary). If you select Annually, enter your full annual salary. For Hourly, enter your hourly rate and hours per week — the calculator converts this to gross for you.
3) What are pre-tax deductions and why do they matter?
Pre-tax deductions (such as traditional 401(k) contributions, health insurance premiums or UK salary-sacrifice pension) are withheld before income tax is calculated. This reduces your taxable income, lowering your tax bill. A $500/month pre-tax 401(k) contribution does not reduce your take-home by $500 — it reduces it by $500 minus the tax you save, making it one of the most efficient ways to build long-term wealth.
4) Why is state tax optional in the US section?
State income tax rules vary enormously — from 0% in states like Texas and Florida to progressive top rates above 13% in California. If you know your effective state rate, enter it directly. If not, select your state and the calculator will apply a simple estimate (or 0% for no-income-tax states). For precise state withholding, consult your state's official withholding tables.
5) Does the UK result include pension contributions and student loan repayments?
This calculator includes estimated PAYE income tax and employee NI. Student loan repayments (Plan 1, 2 or 4) and pension auto-enrolment contributions are not calculated automatically, but you can model them using the pre-tax or post-tax deductions fields. Enter your estimated monthly pension or loan repayment amount there for a more complete picture.
6) Which US states have no income tax?
Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington and Wyoming have no state income tax on wages. New Hampshire taxes only investment income. If you select one of these states, this calculator will return $0 for state tax. Note that some of these states have higher property or sales taxes to compensate — overall tax burden varies.
7) What is the difference between marginal and effective tax rate?
Your marginal rate is the rate applied to the last dollar of your income — i.e., the bracket you're in. Your effective rate is the total tax paid divided by total income — always lower than the marginal rate because lower brackets apply to lower slices of income. This calculator shows your effective tax rate in the results summary. The marginal rate is useful for deciding whether additional income (a raise or bonus) is worth it; the effective rate shows your overall tax burden.
8) How does the UK Personal Allowance tapering affect me?
If your UK income exceeds £100,000, you lose £1 of Personal Allowance for every £2 of income above that threshold. This creates an effective marginal rate of 60% on income between £100,000 and £125,140, because you are paying 40% income tax on the extra income and losing allowance that was previously protecting income from 40% tax. This calculator accounts for the tapered allowance in its UK calculation. Above £125,140 the allowance is fully gone and the 45% additional rate applies.
