How Yepaa builds a planning estimate
France uses Urssaf for the salary and profile. Other countries use the latest complete OECD average-wage reference, with planning bands and identified adjustments. ECB rates update automatically. Service and entity budgets are separate assumptions.
1. Employer contributions
France uses Urssaf for the salary and profile. Other countries use the latest complete OECD average-wage reference, with planning bands and identified adjustments. ECB rates update automatically. Service and entity budgets are separate assumptions.
The OECD employer burden is (labour cost ÷ gross wage − 1) × 100, using one common year and the same PPP unit for both values. PPP amounts are never converted with market exchange rates. The planning band subtracts 2 and adds 3.5 percentage points.
The matching OECD NTCP table adds modelled mandatory private employer payments to labour cost before computing the ratio. All 38 countries must match the CSV reference year; incomplete or changed-format publications preserve the validated snapshot.
Full-time permanent contract, mainland France excluding Alsace-Moselle, general rules, VAT-liable company. Workforce includes planned hires. Empty optional fields use Urssaf defaults. Additional benefits exclude health cover already included by Urssaf.
2. Route costs
Default EOR allowance: US$599–699 per employee/month. Entity incorporation and overhead, contractor administration and optional benefits are planning assumptions. They can be replaced with a quote in the calculator. No public tax API supplies these commercial costs.
The comparison uses the selected horizon: midpoint setup plus prorated midpoint annual overhead, divided by midpoint EOR fees per employee over the same period. The highlighted route has the lower midpoint budget, excluding contractor classification. It is not a legal recommendation.
3. Currency and limits
OECD references are checked daily; the latest complete common year is retained. French calculations are refreshed daily for each anonymous profile, including Urssaf defaults. Results use one coherent ECB dataset. Invalid responses preserve the last validated data with a visible notice; unavailable French calculations fall back to the OECD band. Future law changes and special cases are not forecasts.
The OECD benchmark does not cover every mandatory cost: occupational accident insurance, sector pensions, severance funds and local obligations can require additional budgets. It describes an average-wage profile, not individual payroll law. Bonuses, immigration, deposits, FX margins and future law changes are not included unless explicitly entered. The planning band is an assumption, not a statistical confidence interval.
