Each column uses the country's own currency. The number you entered is treated as the gross salary in that currency — there is no FX conversion. USA figure shows federal tax plus FICA only (state tax excluded — use the main Take-Home Pay calculator for state-level detail).

Worked Example: 100,000 in Each Currency
Punching in 100,000 returns three sharply different take-home figures. In the United States, $100,000 with single filing status leaves roughly $74,400 net after federal income tax and FICA — an effective rate of about 25.6%. In the United Kingdom, £100,000 still benefits from the full Personal Allowance (the taper only starts above £100,000), so income tax runs around £27,432 and NI another £3,766, leaving £68,802 net at an effective rate near 31.2%.
South Africa's R100,000 is below the tax threshold for under-65s, so it pays zero income tax. UIF of R1,000 is the only deduction, leaving R99,000 net — an effective rate of 1%. This wide spread illustrates why the comparison only makes sense currency-by-currency: the same numeric gross sits at very different points in each country's bracket structure.
Pushing the input to 300,000 reveals where the systems converge. A $300,000 US salary nets about $213,500 (28.8%), £300,000 yields £170,500 (43.2%), and R300,000 yields R244,300 (18.6%). The UK's loss of Personal Allowance above £100,000 plus 45% additional rate makes it the harshest jurisdiction at upper-middle incomes, while South Africa's lower-bracket dominance keeps middle salaries lightly taxed.
Common Mistakes Comparing Salaries Internationally
- Comparing gross numbers in different currencies as if FX matters here — this calculator deliberately ignores exchange rates because a salary's purchasing power is tied to its local economy. A £50,000 UK salary buys a UK life; converting it to dollars to compare with a US salary tells you very little useful.
- Forgetting public versus private healthcare — UK take-home does not include NHS-equivalent cost, but US take-home must fund $5,000–$25,000 a year of family health insurance. Adjusting for healthcare often swings the apparent advantage between the two countries.
- Ignoring 401(k) or pension match — comparing pure salary ignores employer-funded retirement contributions. A US job with 6% 401(k) match is effectively higher comp than the headline; UK auto-enrolment minimum is 3% employer, which similarly raises the real take-home figure.
- Treating state tax as optional — California's 9.3%+ rate, New York's 6.85%, and the SALT deduction cap meaningfully reduce US take-home below the federal-only figure shown here. The country-level comparison overstates US take-home for high-tax states.
- Missing the deductions stack — South African RA, US 401(k), and UK pension salary-sacrifice all reduce taxable income. A worker maximising tax-advantaged retirement saving in all three countries enjoys very different effective rates from the gross-tax figures shown here.
When This Tool Does Not Apply
The comparison assumes a single PAYE-style salary. It does not model self-employed earnings (UK Class 4, US self-employment tax, SA provisional tax all change the calculation), dividend income (each country taxes dividends on separate schedules), or rental income. Anyone with a mix of income types should use the country-specific calculators and combine results manually.
It also does not reflect cost of living, public services, or quality-of-life adjustments. A net £60,000 in central London buys a very different lifestyle from a net R600,000 in Cape Town or a net $60,000 in Houston. Take-home pay is one input to relocation decisions, not the whole picture.
Sources and Methodology
US figures use 2026 federal brackets per IRS IR-2025-103, FICA caps from the Social Security Administration, and Medicare additional rate per IRS guidance. UK figures use HMRC's published 2026/27 rates, the £12,570 Personal Allowance frozen until 2028, and standard NI bands. South African figures use the 2026/27 SARS bracket table, primary rebate, and UIF cap. The calculator's bracket arrays are public in the page source for verification.
Actionable Next Steps
- Try your real annual gross to see take-home in each country.
- Then divide by 12 to get monthly net and compare against typical living costs in each market.
- If considering relocation, use this output alongside a cost-of-living comparison tool — both inputs matter.
- For self-employed equivalents, use the per-country Take-Home Pay calculator instead.
- Pension or 401(k) match figures should be added manually to total compensation comparisons.
- Run a second pass with state tax applied via the main Take-Home Pay calculator for US-specific accuracy.
