$5,370 comes out of pay; another $5,370 is paid on top and you never see it
On a $60,000 salary the employee contributes $5,370 and the employer contributes the same again. Only the first half appears on the payslip. The second is a real cost of employing you — the total cost to the employer is $65,370, not $60,000 — and most employees never encounter the figure.
Economists generally argue the employer half is borne by the worker regardless, in the form of wages that are lower than they would otherwise be. Whether or not that holds in full, the practical point stands: the true tax wedge on employment is the sum of both halves, and quoting only the employee side understates it by half.
There is no employer, so both halves land on the same person
Someone self-employed pays both halves themselves. On the same $60,000 of profit the contribution is the full $10,740 rather than $5,370, which is why moving from employment to self-employment at an unchanged headline income produces a substantially lower net figure.
Most systems soften this. The self-employed typically deduct half the contribution when computing income tax, and the base is often slightly reduced before the rate applies. The relief rarely offsets the full doubling, and pricing self-employed work at an employed salary without accounting for it is a common and expensive mistake.
Social contributions usually cap; health contributions usually do not
Most systems apply the social security portion only up to an annual ceiling, above which the marginal payroll rate drops sharply. The health or medicare portion generally has no ceiling and often gains an additional surcharge above a high threshold, so the combined rate falls at one point and rises again at another.
This calculator applies flat rates throughout, which is accurate below the ceiling and overstates the contribution above it. For a high salary, the effective payroll rate can be several points below the headline figure computed here, and that gap matters when comparing total employment cost across salary levels.
Thresholds, caps, surcharges and every jurisdiction-specific rule
Rates, ceilings and the definition of qualifying pay differ by country and frequently by region. Some systems exempt an initial band entirely; others apply different rates to different categories of worker; several add employer-only levies that appear in none of these fields.
Benefits in kind, bonuses and equity compensation may be treated differently again, and pension contributions often reduce the base before the rate applies. Use this to understand the structure — two halves, a ceiling, and a total cost above the salary — and the official schedule for figures you will act on.
