Fully burdened employment cost
Total amount an employer pays to keep one employee on staff, including gross salary, employer-side social security and payroll taxes, mandatory benefits, statutory leave loadings, voluntary benefits, and indirect overhead. Often called true employment cost or loaded labour cost. Typically 1.20 to 2.00 times base salary depending on country.
Fully burdened employment cost is the total amount an employer pays to keep one employee on staff, summing far more than gross salary.
For global payroll and finance teams, the real question isn't whether to include the on-costs. It's which lines actually belong in the figure, and which the EOR or local payroll provider is quietly carrying on the buyer's behalf.
The gross salary on the offer letter is usually the smallest visible line. Employer social security, mandatory benefits, statutory leave loadings, voluntary benefits, and indirect overhead stack on top.
The multiplier varies sharply by country. The US runs around 1.25 to 1.35 times base; the UK sits at 1.20 to 1.30.
France pushes 1.45 to 1.55 once URSSAF contributions land. Brazil reaches 1.80 to 2.00 once INSS, FGTS, and the 13th-month obligation are stacked.
What the gross salary on the offer letter leaves out
Offer letters and headcount-plan spreadsheets usually carry one number: the gross annual salary. That figure is the floor of the employment cost, not the ceiling.
What the headline number misses
Five other cost lines sit below the visible gross. Each is mandatory, country-specific, and rarely modelled at offer-letter stage.
- Employer social security: levied on top of gross at country rates ranging from 7.65% (US FICA) to 30%+ (France URSSAF).
- Statutory benefits: mandatory health, pension, unemployment, workers' compensation, family leave funds.
- Statutory leave loadings: 13th-month salary in Italy, Spain, Brazil, and most of Latin America; holiday allowances in the Netherlands and Belgium.
- Voluntary benefits: private health, life insurance, equipment, software licences, learning budgets.
- Indirect overhead: payroll software, HR admin, statutory filings, audit fees, legal, EOR margin.
Why finance teams miss them
The on-costs sit on different invoices and different cycles. Social charges show on the monthly payroll report; statutory benefits land on quarterly contribution returns.
EOR margin appears on the provider seat fee. By the time year-end reconciliation joins them up, the headcount plan is already a year out of date.
Accurate employer contributions modelling has to capture every line at hiring approval, not at year-end.
The six layers that stack into fully burdened cost
The build-up follows a consistent shape across countries, even though the percentages differ. Six layers, one stacked on the next.
| Layer | What it covers | Typical range | Who confirms it |
|---|---|---|---|
| 1. Gross salary | Base pay before deductions | Offer letter figure | Hiring manager |
| 2. Employer social security | Statutory payroll contributions | 7.65% to 40% of gross | Local payroll or EOR |
| 3. Statutory benefits | Mandatory health, pension, workers' comp | 2% to 12% of gross | Benefits provider |
| 4. Statutory leave loadings | 13th month, holiday allowance, vacation reserves | 0% (US) to 16.7% (Brazil) | Local payroll |
| 5. Voluntary benefits | Private health, equity, equipment, training | 3% to 12% of gross | People Ops |
| 6. Indirect overhead | Payroll software, HR admin, EOR margin, audit, legal | 5% to 15% of gross | Finance plus EOR |
Where statutory leave loadings actually bite
Italy, Spain, and Latin America require a 13th-month payment in December (and Brazil pays a 14th-month vacation bonus too). The Netherlands runs an 8% holiday allowance on top of base. These show as 0% on the monthly payroll but materialise in the annual cost.
Where the EOR margin sits
Most global EOR providers price at 10 to 15% of gross or a flat $599 to $699 per seat per month, whichever is higher. The margin covers local entity maintenance, statutory filings, and the indemnity the EOR carries as legal employer of record. See our Deel review for the line-item view.
Country-by-country: how much gross gets multiplied where
The headline social-security rate is only the first layer. Statutory leave, mandatory funds, and country-specific surcharges shift the multiplier well above the simple percentage suggests.
| Country | Employer social charges | Statutory leave loading | Typical multiplier | Watch-out |
|---|---|---|---|---|
| United States | 7.65% FICA + FUTA + SUTA | None statutory | 1.25 to 1.35x | Health insurance is the heavy line |
| United Kingdom | 13.8% NI above £9,100 | Statutory holiday accrual | 1.20 to 1.30x | Apprenticeship Levy at £3m wage bill |
| Germany | Approx. 20% to 21% to contribution ceiling | 20 days statutory minimum | 1.28 to 1.35x | Employer accident insurance on top |
| France | URSSAF 25% to 30%+ | 25 days plus RTT | 1.45 to 1.55x | Highest mandatory load in the EU |
| Italy | INPS 28% to 32% | 13th + 14th month + TFR | 1.35 to 1.50x | TFR severance reserve at 7.4%/year |
| Brazil | INSS 20% + FGTS 8% + others | 13th month + 1/3 holiday bonus | 1.80 to 2.00x | Provisão for vacation and termination |
| India | PF 12% + ESI on lower bands | Gratuity at 4.81% accrual | 1.20 to 1.25x | Lower mandatory load than EU |

Why Brazil and France cost so much more
Brazil layers INSS, FGTS, system-S contributions, and the 13th-month obligation on the same payroll, then requires the employer to hold provisões against future vacation and termination liability. France runs URSSAF at 25 to 30% plus separate retirement and unemployment funds. Both push the multiplier well past 1.5x.
Why the US looks cheap until benefits land
US employer payroll taxes look low (7.65% FICA plus FUTA and SUTA). Then private health insurance, 401(k) match, and short-term disability coverage land on top, often adding 15 to 25% of gross before the headcount plan is signed.
What changes when you hire through an EOR
An EOR shifts the cost structure but doesn't shrink it. The same statutory contributions still fund the same statutory schemes. The EOR adds a margin and removes the entity-maintenance line.
| Cost line | Own entity | EOR route | Net difference |
|---|---|---|---|
| Employer social charges | Paid direct | Paid via EOR; pass-through | Same |
| Statutory benefits | Paid direct | Paid via EOR; pass-through | Same |
| Payroll software | Buyer pays | Bundled in seat fee | Lower for EOR |
| Local HR admin | In-house team | Bundled in seat fee | Lower for EOR |
| Statutory filings | In-house plus tax adviser | Bundled in seat fee | Lower for EOR |
| Audit and legal | Annual entity audit | Carried by EOR | Lower for EOR |
| EOR service fee | Not applicable | $599 to $699 / month or 10 to 15% of gross | Added line |
The crossover usually sits at 3 to 5 employees per country. Below that, the EOR seat fee is cheaper than entity maintenance. Above that, an own entity is normally cheaper per head, depending on country.

Whichapp view
The fully burdened cost is the only honest figure for headcount planning. Approving hires on gross salary alone routinely underprices the headcount budget by 25 to 40%, and the variance lands as a finance surprise nine months later.

Modelling fully burdened cost before you sign the offer
The point of the calculation is the approval gate, not the year-end report. Three checklists keep the figure honest at hiring.
Pre-offer modelling checklist
- Has gross salary been confirmed in offer-letter currency?
- Are employer social charges modelled at country-specific rates, not a blanket 20%?
- Are statutory leave loadings (13th month, holiday allowance) included?
- Is mandatory health, pension, and workers' comp counted separately from voluntary benefits?
- Are voluntary benefits set against company benefits policy, not the local market average?
- Is the EOR margin included on the all-in figure?
- Is the multiplier compared against country-band data, not a US default?
- Has the figure been run against the employer cost burden calculator?
Questions for the EOR or local payroll provider
- Which employer-side contributions are passed through versus loaded?
- How is the seat fee priced: flat, percentage of gross, or hybrid?
- Are statutory leave provisions held in a reserve or accrued live?
- What does the provider charge for terminations, bonuses, and equity grants?
- How are FX conversions handled when the offer letter is in USD or GBP and payroll is local?
Worked example: Germany €100,000 hire
Illustrative case: a Berlin-based employee hired on a €100,000 base via an EOR. Figures rounded; exact treatment depends on age, family status, and provider pricing.
| Line | Amount (EUR) | Notes |
|---|---|---|
| Gross base salary | €100,000 | Offer letter figure |
| Employer social contributions | €14,500 | Approx. 21% up to ceiling |
| Employer accident insurance | €800 | Berufsgenossenschaft |
| Statutory holiday accrual | €2,500 | Reserve for unused leave |
| Voluntary private health top-up | €3,000 | Company policy |
| EOR seat fee | €8,400 | €699/month flat |
| Equipment and software | €3,800 | Laptop, licences, home-office |
| Total fully burdened cost | €133,000 | 1.33x base salary |
The €100,000 base on the offer letter is 75% of the actual employment cost. A finance team approving hires on the gross figure alone is underbudgeting by a third on every German seat.
For mobility cases that layer host-country tax on top, see tax equalisation and gross-up. France adds further on-cost complexity (see the France country guide).

How is fully burdened cost different from gross salary?
Gross salary is the base pay figure on the offer letter, before any deductions. Fully burdened cost adds employer social security, mandatory benefits, statutory leave loadings, voluntary benefits, and indirect overhead.
The fully burdened figure is usually 1.20 to 2.00 times gross, depending on country, and it's the only honest number for headcount budget approval.
What's a typical multiplier for fully burdened cost?
The multiplier varies sharply by country. The US sits around 1.25 to 1.35 times gross; the UK runs 1.20 to 1.30.
Germany lands at 1.28 to 1.35. France pushes 1.45 to 1.55, and Italy reaches 1.35 to 1.50 once 13th and 14th-month obligations are included.
Brazil tops the table at 1.80 to 2.00 once INSS, FGTS, and provisões land. See employer cost ratio for the comparable per-country figure.
Does fully burdened cost include the EOR fee?
Yes. The EOR margin is part of the indirect-overhead layer when the buyer hires through an employer of record.
It typically runs $599 to $699 per seat per month, or 10 to 15% of gross, whichever is higher. Excluding it from the fully burdened figure understates the true cost of the EOR route and makes the comparison against own-entity hiring misleading.
Is fully burdened cost the same as total cost of employment?
Mostly yes. The terms are used interchangeably, alongside loaded labour cost and true employment cost.
All of them refer to the all-in figure that sums gross salary, mandatory contributions, voluntary benefits, and overhead. The only nuance: some finance teams exclude voluntary benefits to keep the figure comparable across countries with different benefits norms.
When should fully burdened cost be modelled?
At offer-letter stage, before the hiring decision is approved. Running the figure later doesn't change the budget; it just confirms the variance.
Use a calculator or country-specific employer-rate table at the moment the hire is being signed off, and store the figure against the headcount line for actuals tracking. The employer cost burden calculator covers the standard layers.
