How we calculate and rank EOR costs

What we calculate

For every salary + country + provider combination, we compute the total monthly employer outlay as:

total_monthly =
    gross_salary
  + statutory_employer_contributions(country, gross_salary)
  + platform_monthly_fee
  + fx_spread * (salary + employer_contributions + fee)
  + amortised_one_time_fees (setup + offboarding, spread over expected tenure)

Data sources

• Statutory employer contributions: each country's tax authority and social-security agency, plus the OECD Taxing Wages dataset as cross-check.
• Platform monthly fees: each provider's public pricing page, captured on the date shown on the provider's pricing route.
• FX rates: mid-market rates plus an explicit platform spread assumption shown on every calculation (typical range 0.5%–3% depending on provider).
• Country deep-dives: statutory contributions, mandatory benefits, and termination rules sourced from local labour codes; dates of last review are shown on each country page.

How rankings work

Provider cards are ordered by lowest total monthly cost for the salary and country you enter. The badge labelled "Lowest total cost" marks the cheapest provider for the current inputs and updates on every change. Ranking is arithmetic — we do not accept payment for placement, and commission rates do not influence order. Details and legal basis on our Affiliate Disclosure page.

What we don't model

• Volume discounts negotiated with individual providers.
• 13th- and 14th-month payments where they are paid in lump sums (we annualise into monthly cost).
• Employee-side income tax (we only model the employer-side cost).
• Equity, bonuses, and one-off relocation expenses.

Update cadence

Platform fees and FX assumptions are reviewed monthly. Country statutory rates are reviewed quarterly and whenever a country publishes a budget or tax-table change. Each country page shows its individual last-reviewed date.

Corrections policy

If you spot an outdated rate, a missing statutory contribution, or a provider fee that has changed, email hello@eorlens.com with a primary source. Corrections are applied within five business days and the country page's last-reviewed date is bumped. Material corrections are noted at the bottom of the affected page.
