Payroll Calculator

This calculator gives estimates, and each country's result names the tax year its rates were checked against. For the United States, it uses the 2026 IRS federal income tax brackets, the 2026 standard deduction ($16,100 for single filers), the 2026 Social Security wage base ($184,500), and current FICA rates. For the UK, it uses the 2026/27 personal allowance (£12,570), income tax rates, and NIC thresholds. Some inputs are simplified averages, such as US state tax and Canadian provincial tax. Actual deductions may vary based on: state/provincial taxes (for US/Canada), local taxes, additional voluntary contributions, tax credits, and employer-specific deductions. Always confirm final calculations with your payroll department or a tax professional.

Gross pay is your total salary before any deductions — the number typically quoted in job offers and employment contracts. Net pay (also called "take-home pay") is what actually lands in your bank account after income taxes, social security contributions, health insurance premiums, pension contributions, and any other deductions are removed. The gap between gross and net can be significant: in the US, a $100,000 gross salary typically results in $68,000–$75,000 net pay. In Germany, the same €100,000 gross may yield only €55,000–€62,000 net.

These are two different ways to measure tax burden. The marginal tax rate is the rate applied to the last dollar (or pound/euro) of your income — it is the rate of your highest tax bracket. The effective tax rate (also called average tax rate) is the total tax paid divided by your gross income. Because most countries use progressive taxation, your effective rate will always be lower than your marginal rate. For example, a single US taxpayer earning $150,000 in 2026 has a federal marginal rate of 24% but an effective federal income tax rate of about 16.5%, because the $16,100 standard deduction is not taxed and the first $50,400 of taxable income is taxed at 10-12%. This calculator shows both rates.

US payroll taxes consist of federal income tax, state income tax, and FICA taxes. Federal income tax uses seven progressive brackets (10%, 12%, 22%, 24%, 32%, 35%, 37%) with the standard deduction ($16,100 for single filers in 2026) reducing your taxable income. FICA taxes are: Social Security at 6.2% on wages up to $184,500 (the 2026 wage base), and Medicare at 1.45% on all wages (plus an additional 0.9% surtax on wages exceeding $200,000). State income taxes vary from 0% (Texas, Florida, etc.) to over 13% (California top rate). This calculator uses a weighted average state rate.

Employee social contributions take a large share of French gross pay before income tax; this calculator applies a simplified flat 21%. In 2026 they include basic pension contributions (6.90% up to the social security ceiling plus 0.40% on all pay) and CSG/CRDS (9.70% on 98.25% of gross pay), plus supplementary pension contributions; outside Alsace-Moselle, employees pay no separate health insurance contribution. On top of these, income tax is progressive up to 45% (2026 scale). For a single person earning €80,000 gross, this calculator estimates about €51,100 net, an effective deduction rate of about 36%. The tradeoff is comprehensive public healthcare, generous unemployment benefits, and a strong pension system.

Singapore's Central Provident Fund (CPF) is a mandatory social security savings scheme. From 1 January 2026, employee CPF contribution rates for Singapore Citizens and Permanent Residents (from the third year) are 20% for employees aged 55 and below, 18% above 55 to 60, 12.5% above 60 to 65, 7.5% above 65 to 70, and 5% above 70. Contributions on ordinary wages are capped at the ordinary wage ceiling (S$8,000/month = S$96,000/year). While CPF reduces monthly take-home, it is not "lost" money — it accumulates in CPF accounts (Ordinary Account for housing/education, Special Account for retirement, MediSave for healthcare) and earns 2.5% to 4% base interest, and up to 6% with extra interest.

The additional deductions field is for voluntary pre-tax contributions that further reduce your taxable income. Common examples include: US — 401k contributions (up to $24,500 in 2026), HSA contributions ($4,400 self-only/$8,750 family in 2026), FSA contributions, traditional IRA contributions; UK — SIPP pension contributions, salary sacrifice arrangements; Germany — Riester pension (Vorsorgeaufwendungen); Canada — RRSP contributions, DPSP; Australia — salary sacrifice contributions (in addition to employer Super). Note: some deductions are post-tax (Roth 401k, etc.) and would not reduce your taxable income — only include pre-tax contributions in this field.

Odoo Payroll includes country-specific localizations that automatically apply the correct tax brackets, social security rates, and deduction rules for 50+ countries. Instead of manually tracking which bracket each employee falls into each month, Odoo calculates the correct withholding, generates payslips, handles year-end adjustments, and produces the statutory reports required by each jurisdiction. For companies with employees in multiple countries, this eliminates the complexity of maintaining separate payroll systems or spreadsheets. ECOSIRE specializes in implementing Odoo Payroll for international organizations, including custom country localizations and integration with local labor law requirements.
