Employer cost, not just take-home
The full cost of employing someone, including every employer-side contribution. This is the number behind “what does it cost us to hire in Germany?” — the question a quote, a budget or an offer is built on.
A European payroll tax engine you can licence, instead of building
Saldora calculates net pay, tax, social security and full employer cost across 15 European countries — for employees and freelancers, in both directions, from one REST API. If your product needs those numbers to be right and to stay right, this is what we sell.

Why teams stop building this themselves
One country is a week's work to get roughly right and a permanent commitment to keep right. Brackets move, contribution ceilings are re-indexed every January, and the errors that hurt are never in the headline rate — they hide in a social-security cap or a standard deduction that quietly went a year out of date, still returning a plausible number.
Multiply that by every country on your roadmap and it is not a feature any more, it is a standing research obligation that competes with your actual product for engineering time. That obligation is what you are buying here.
What you get that a calculator will not give you
Net-to-gross, both directions
Start from a target net and get the gross that produces it. Payroll and EOR flows need this constantly, and almost no competitor exposes it — it is far harder than running the calculation forwards.
Cross-country comparison in one call
Rank net pay across countries in a single request, converted across currencies with dated FX. Relocation, mobility and “where should this role sit?” tooling, without orchestrating 15 calls yourself.
Who watches the rules after you integrate
Naming a source proves where a figure came from. It does not prove anyone is still looking at it — and that is the part that decides whether an integration is still correct in eighteen months. Rates move mid-year and nobody tells the people who built on them. Czechia's self-employed figures changed in July 2026 and applied retroactively to January; Bulgaria's contribution ceiling moved on 1 August; the Greek healthcare branch was cut a full point and most published tables still carry the old number.
So every change to our tax data is dated, sourced and published — including the figures we had wrong and found by checking against the statute. A vendor with no corrections to show is one that has not looked, and you are entitled to see the difference before you depend on it.

Plain REST, no SDK
JSON in, JSON out, documented with OpenAPI and Swagger. Integrate in an afternoon in any language, with no client library to keep in step.
Nothing is stored
The service is stateless: salaries you send are calculated and discarded, never persisted. There is no personal data at rest here to appear in your DPA, your risk register or a breach.
Auditable answers
Every response carries its tax year and effective date, and /methodology returns the sources behind each country. When your customer asks why a figure is what it is, you can show them.
Maintained, not published once
Rates, bands, caps and thresholds are re-verified against primary sources — currently tax year 2026. Maintenance is the product; the code is the easy part.

Questions we get asked
- Which countries are covered?
- The live list is always at /api/v1/countries — it is the authoritative source, not a page that can go stale. If a country you need is missing, say so in your enquiry: demand from a paying customer is what decides the order they are added in.
- How do I know the numbers are right?
- Every country's figures are taken from the statute or the tax authority's own circular, and the sources are exposed through the /methodology endpoint so you can check them. The calculators are covered by an extensive automated test suite that pins published figures, so a change that moves a number has to be deliberate. Try any case on the public calculator before you talk to us — it runs on exactly the same engine as the API.
- How is this different from subscribing on RapidAPI?
- The same engine, bought differently. RapidAPI is self-serve, metered and billed by them, with fixed tiers — good for trying it out and for smaller volumes. A direct agreement means invoicing from us, limits set to what you actually need, a direct line for support, and a say in which countries come next.
- What does it cost?
- It depends on volume and on what you need beyond the standard endpoints, so there is no single number to quote honestly. Tell us your expected volume and we will come back with a concrete figure rather than a range.
- Can we trial it before committing?
- Yes. The public calculator uses the same engine and needs no signup, and we can issue a time-limited key for your own testing so you can integrate against the real API before anything is signed.
- Do you sign DPAs, contracts and security reviews?
- Yes — send yours over. It helps that the service holds no personal data at rest, which removes most of what a data-processing review is usually concerned with.
