Gross salary
Salary is set by the local market rather than by the provider, and it dwarfs everything else on the invoice. Because every other layer is calculated as a percentage of gross pay, one salary decision at hiring compounds through contributions, severance accrual, and any percentage-based fee.
Mandatory employer contributions
Statutory contributions are the layer buyers underestimate most, because they barely register in a US-anchored view of payroll. OECD data for 2025 puts employer contributions and payroll taxes at 26.7 percent of total labor cost in France, the highest in the OECD, with eight other countries above 20 percent, including Austria, Belgium, Italy, Spain, and Sweden [7]. Ask for the country-specific employer burden before you agree a salary.
Statutory benefits and mandated insurance
Benefits arrive as their own line because many countries require cover a US employer would treat as discretionary. Deel's cost calculator returns a benefits array with a plan name, a cost, and any attached fees, separate from employer costs and the platform fee [6], and providers differ on whether a medical top-up is bundled or billed.
The EOR platform fee
The platform fee buys the entity, the compliance work, and the payroll operation. Deel describes its fee as covering onboarding and local compliance, payroll processing and tax filings, benefits administration, and ongoing HR and legal support [1], while Remote charges no separate platform or setup fee [2] and Oyster includes setup, onboarding, and offboarding [3].
Severance accrual and security deposits
Cash gets tied up here long before anyone is terminated. Oyster requires a refundable deposit to start an engagement [3] and Remote collects reserves only in rare, high risk circumstances [2], while Deel treats severance accrual as its own field, so where termination pay scales with service the accrual is billed as you go [6].
Currency conversion and payment fees
You pay the provider in your billing currency and the provider pays the worker in theirs, and the gap between those rates is a real cost. Remote states that its FX rate varies over time and by currency pair [2], Oyster charges conversion only when the payment currency differs from the contract currency [3], and Safeguard Global lists FX markups and wire fees among charges outside the base rate [14].
Onboarding, offboarding, and administrative charges
One-time charges vary more between providers than the monthly rate does. RemoFirst publishes no setup, onboarding, or termination fees [4] and Oyster folds setup and offboarding into its rate [3], while Safeguard Global names setup fees, off-cycle payroll charges, and termination processing fees as common extras [14].
