Tax Break-Even Calculator
Updated May 2026· By Net Life Value Editorial
Pick two countries. We compute PPP-adjusted take-home across 8 salary levels and surface the salary at which one country overtakes the other on lived purchasing power. Both income tax and social contributions are included via our country-specific tax engines.
Break-even at $68,000 gross. Below this, 🇵🇹 Portugal gives more PPP-adjusted purchasing power. Above this, 🇺🇸 United States takes the lead.
| Salary (USD) | 🇺🇸 United States — PPP net | 🇵🇹 Portugal — PPP net | Winner |
|---|---|---|---|
| $30,000 | $25,762 | $28,668 | 🇵🇹 Portugal |
| $50,000 | $40,968 | $42,578 | 🇵🇹 Portugal |
| $75,000 | $58,131 | $57,467 | 🇺🇸 United States |
| $100,000 | $73,409 | $71,853 | 🇺🇸 United States |
| $125,000 | $88,538 | $85,520 | 🇺🇸 United States |
| $150,000 | $103,301 | $99,187 | 🇺🇸 United States |
| $200,000 | $134,308 | $126,520 | 🇺🇸 United States |
| $300,000 | $180,327 | $181,186 | 🇵🇹 Portugal |
PPP net = (USD take-home after taxes) ÷ (country price level / 100). Compares lived purchasing power, not raw USD income.
How the calculation works
For each salary level, we run the source and target through their country-specific tax engines (US progressive federal-only, France quotient familial, UK PA taper, etc.). The result is USD net income after all taxes and employee social contributions.
We then divide that USD net by the country's World Bank price level (US = 100). The result is PPP-adjusted purchasing power— roughly "how much US-equivalent stuff your salary buys". That's the column we compare across countries.
The break-even is the salary at which the two countries deliver equal PPP-adjusted purchasing power. We compute it via linear interpolation between the two adjacent salary points where the ordering flips — accurate to within a few hundred dollars.
What we don't capture: state/regional tax (US California adds ~5pp), wealth tax, capital gains, healthcare premiums for self-pay countries (US, AE), and quality-of-life dimensions. The break-even answers the literal financial question; for the full picture cross with NLV and the Safe-and-Cheap Pareto frontier.
