Salary Calculator — Gross to Net Pay with Progressive Tax Brackets
This salary calculator estimates your net (take-home) pay from your gross salary using configurable progressive tax brackets. In a progressive system, income is taxed in slices: each portion of your salary that falls within a bracket is taxed at that bracket's rate, so a raise never reduces your take-home pay. The tool shows a full breakdown of deductions and your effective tax rate — the real percentage of your salary that goes to taxes.
Because tax rules vary by country and change over time, the brackets are fully editable: adjust thresholds, rates, and fixed deductions to match your local payroll rules, social security contributions, or pension deductions. This makes the calculator useful whether you are evaluating a job offer, planning a budget, or simply checking that your payslip adds up.
How it works
Tax = Σ (taxable amount within each bracket × bracket rate); Net salary = Gross − Tax − other deductions; Effective rate = Total tax ÷ Gross × 100. Only the portion of income inside each bracket is taxed at that bracket's rate (marginal taxation).
Use cases
- Converting a gross salary offer into the real monthly take-home amount
- Comparing two job offers with different gross salaries and deductions
- Checking whether the deductions on your payslip match the official brackets
- Estimating how much of a raise actually reaches your bank account
- Planning a household budget based on realistic net income
- Simulating payroll costs and net pay for freelancers or small employers
Frequently asked questions
What is the difference between gross and net salary?
Gross salary is the total amount agreed with your employer before any deductions. Net salary, also called take-home pay, is what actually lands in your bank account after income tax, social security contributions, and other mandatory or voluntary deductions. The gap between the two depends on your income level and local tax rules, and this calculator itemizes exactly where each part goes.
How do progressive tax brackets work?
In a progressive system, your income is divided into slices and each slice is taxed at its own rate. For example, if the first bracket covers income up to 2,000 at 0% and the next taxes 2,000–3,000 at 10%, someone earning 2,500 pays tax only on the 500 that falls in the second bracket. This is called marginal taxation, and it means moving into a higher bracket never reduces your net pay.
What is the effective tax rate?
The effective rate is the total tax you pay divided by your gross salary, expressed as a percentage. It is always lower than your top marginal rate because the first slices of your income are taxed at lower rates or not at all. For instance, someone in a 27.5% top bracket might have an effective rate of only 15%, since much of their income was taxed in the lower brackets.
Why can I edit the tax brackets in this calculator?
Income tax tables, social security ceilings, and deduction values differ by country and are updated regularly by governments. Editable brackets let you enter the exact current values for your jurisdiction — Brazil's IRRF and INSS tables, Spain's IRPF, US federal brackets, or any other system — so the estimate stays accurate instead of relying on hardcoded rules that go stale.
Does the result match my official payslip exactly?
It is a close estimate, but payslips often include items the calculator cannot know in advance: dependent allowances, union dues, health plan copayments, meal vouchers, benefits, or court-ordered deductions. Enter those as additional deductions to refine the result. For official figures, always check your payslip or consult your HR department or an accountant.
