If you're working or planning to work in Portugal, understanding your net salary after taxes and social security deductions is essential. Whether you're a local resident or an expat relocating to Portugal, this free wage simulator gives you an instant, reliable estimate of your take-home pay — all directly in your browser.
This tool is particularly useful for:
- Professionals moving to Portugal
- Remote workers based in Portugal
- Employers estimating payroll costs
- Job seekers comparing gross offers with actual income
This lightweight, browser-based tool lets you simulate your monthly and annual net salary, taking into account:
- Gross wage
- Marital status
- Number of dependents (children)
- Non-Habitual Resident (NHR) tax regime
- Custom deductions
What is the Portugal Wage Simulator?
The Portugal Wage Simulator is a lightweight, interactive tool built using Vue.js (via CDN) that runs entirely in the browser — no installs, no logins, no tracking.
With just a few clicks, you can simulate:
- Gross monthly salary (with a dynamic slider)
- Marital status and household type
- Number of dependents (children)
- Special regimes like the Non-Habitual Resident (NHR) tax benefit
- Additional monthly deductions (e.g. union dues, meal cards)
The simulator then calculates:
- IRS tax (imposto sobre o rendimento de pessoas singulares) based on simplified 2024 brackets
- Employee Social Security contributions (11%)
- Employer Social Security costs (23.75%)
- Net monthly and annual income (considering 14 payments/year)
This allows users to better understand their expected net income in Portugal, especially useful for relocation planning, salary negotiations, and financial decisions.
You can move a slider to set your gross monthly income and instantly see how income tax (IRS), social security, and other deductions affect your take-home pay.
What’s Behind the Calculator?
The app is built using Vue 3 + CDN — meaning it’s fast, requires no installation, and works even offline. Here’s a breakdown of the main logic inside the JavaScript <script> block that powers the calculations:
const wage = ref(1500);
This stores your gross monthly wage, reactive to the slider input.
const dependents = ref(0);
const maritalStatus = ref('single');
const isNhr = ref(false);
const otherDeductions = ref(0);
These variables represent user-selected options:
- Marital status (single, married_one_income, married_two_incomes)
- Number of children/dependents
- Whether the user qualifies for NHR (Non-Habitual Resident tax regime)
- Any custom deductions (e.g. union dues, meal cards)
IRS Tax Calculation:
const irs = computed(() => { ... });
This block simulates Portugal’s IRS tax system, using simplified monthly brackets based on annual tax bands:
- If the user is under the NHR regime, a flat 20% tax is applied.
- Otherwise, a progressive tax rate is applied, with deductions:
- Married individuals receive a discount.
- Children reduce IRS by €50 per dependent (illustrative).
Note: This doesn't replace Finanças official calculations — it's educational and directional.
const ssEmployee = computed(() => salary * 0.11);
const ssEmployer = computed(() => salary * 0.2375);
These apply Portuguese standard rates:
Employees: 11%
Employers: 23.75%
Net and Annual Salary
const net = computed(() => salary - irs - ssEmployee - otherDeductions);
const annualNet = computed(() => net * 14);
In Portugal, salaries are commonly paid in 14 months per year (12 + Christmas + vacation pay), so both monthly and annual net salary are calculated.
