Gross vs net salary: how to compare job offers across countries

A $100,000 offer in the US, a £75,000 offer in London, a R$ 200,000 offer in São Paulo, and a 60.000 € offer in Madrid are not directly comparable. Each country has different income tax structures, social security contributions, and embedded benefits. Comparing them with a simple exchange rate is the fastest way to make a bad career decision.

Why gross-to-net ratios differ wildly

Three factors dominate the gap between gross and net pay:

Income tax progressivity — flat-rate countries (e.g., Bulgaria 10%) leave very different net pay than steeply progressive systems (e.g., Belgium up to 50%)
Social security weight — Spain takes ~6.4% from the employee but 30% from the employer, creating a big gap between "cost to company" and "take-home pay"
Embedded benefits — Brazilian CLT includes a 13th salary, 1/3 vacation bonus, and 8% FGTS deposit, all paid by the employer on top of the headline salary

The United States

Federal income tax (10–37% progressive) + state tax (0–13%) + FICA (7.65% Social Security and Medicare) + health insurance premiums (often $200–800/month from paycheck even with employer plan).

Effective gross-to-net for a $100,000 single filer in California: about $68,000–72,000 take-home depending on 401k contributions, deductions, and health plan.

The US system is unique in tying healthcare to employment. Losing the job means losing health coverage (with COBRA available at full premium for 18 months). Bake the value of employer-provided health insurance into any offer comparison.

The United Kingdom

Income tax (20% up to £50,270, then 40% to £125,140, then 45%) + National Insurance (8% in band, 2% above) + employer pension contributions (3% minimum auto-enrolment).

Effective gross-to-net for a £75,000 salary: about £52,000–54,000 take-home, depending on pension contributions. National Insurance is mostly invisible to workers but adds about 8 percentage points to the effective tax burden.

Brazil (CLT regime)

INSS (progressive, capped around R$ 951/month at the ceiling) + IRRF (progressive 0–27.5%) + sometimes union contributions or occupational risk levies.

For a R$ 12,000/month CLT salary: about R$ 8,900 net per paycheck, but with substantial extras: 13th salary (one extra month per year), vacation with 1/3 bonus, 8% FGTS (employer-funded fund the employee can access on dismissal). True annual compensation is around R$ 17,500/month-equivalent when amortized.

Spain

IRPF (progressive, with state and regional brackets, effective 19–47%) + Social Security (6.35% employee). Salary is paid in 12 or 14 payments per year — the 14-payment structure spreads the same gross over more checks but doesn't change the annual total.

For a 60,000 €/year (in 14 payments): about 45,000 € annual take-home. Spanish offers are typically negotiated as gross annual; always confirm whether the figure is in 12 or 14 payments before comparing monthly numbers.

How to actually compare offers across countries

Translate everything to net annual pay in local currency. Use our Spain calculator and Brazil CLT calculator for accurate per-country numbers.
Adjust for cost of living using comparable cities. $100K in Manhattan ≠ $100K in Memphis. Use Numbeo or Expatistan for COL ratios.
Add the value of healthcare and pensions. US offers without health insurance need an extra $8K–15K/year added; UK private-sector pensions of 5%+ are real money.
Factor in tax-free benefits. Spanish "ticket restaurante", German company cars at low BIK, Brazilian VR/VA — all reduce taxable income or increase real purchasing power.
Consider exchange rate volatility. If you plan to repatriate savings, a salary in BRL or ARS carries currency risk a USD or EUR salary doesn't.

The hidden traps

The 14-payment trick: Spanish "60.000 € en 14 pagas" means 60,000 € total annual gross, paid in 14 installments. Some companies advertise the figure misleadingly. Always confirm: is this annual or monthly?

Bonus structures: A "target bonus of 30%" is wildly different from "guaranteed bonus of 30%". Most American tech offers tie bonus to performance ratings, with actual payouts averaging 70–90% of target.

Equity vs salary: RSUs vesting over 4 years aren't cash this year. Apply a discount (30–50%) for vesting risk and tax timing before comparing to a higher cash offer.

Conclusion

Headline salary numbers across countries are nearly meaningless without translation to net pay, cost-of-living adjustment, and benefits inclusion. Take the time to do the math properly. The wrong currency in your bank account at the end of the year doesn't care that the offer letter looked impressive.
