13ª13th-month payItaly 13th-month pay calculator
Base pay and fixed monthly items, as shown on your payslip. No overtime.
A month counts if you worked at least 15 days in it.
Usually 9.19%.
Estimate using the 2026 IRPEF brackets (23, 33 and 43%) divided by twelve, as the employer does for the 13th-month pay. At year end the tax adjustment (conguaglio) recalculates the tax on the whole year's income, and the tax credits missing here show up in your other payslips.
Frequently asked questions
How the 13th-month pay works
How is the tredicesima worked out?
Divide the gross monthly pay by twelve and multiply by the months worked between 1 January and 31 December. With a full year of work the gross tredicesima equals one gross monthly salary.
Why is the net tredicesima lower than a normal month?
Because Italian income tax (IRPEF) on the tredicesima is withheld without the deductions for employees, which are already spread over the twelve ordinary payslips. INPS contributions are the same, usually 9.19%. The year end adjustment then recalculates the whole year.
When does a month count?
In most national collective agreements a month counts if you worked at least 15 days in it. Holidays, sick leave and compulsory maternity leave usually accrue the tredicesima, unpaid leave does not: your contract has the final word.
When is it paid?
Usually with the December salary, before Christmas. If you leave the job during the year, the share accrued so far comes in the last payslip, together with the TFR severance pay.
Does my data stay private?
Yes, and not because we promise it: this tool runs entirely inside your browser. What you type or upload never leaves your device, so it never reaches a server of ours and there is nothing we could keep, read or lose. You can check it yourself: open the page, disconnect from the internet, and the tool keeps working.
Do you store what I enter?
No. There is no database behind this tool: we do not store your files, your text or your results. When you close the tab nothing is left — not here with us, because it never arrived, and not anywhere else.
Do you profile me? Are you GDPR compliant?
We do not profile you: there is no account to create, we never ask for your email to use a tool, and we keep no profile of what you do. We are an Italian company and we work under the GDPR and the other European rules, with the privacy notice and the consent request in plain sight. One thing we say in full rather than hiding it behind a slogan: the ads are Google's, and Google may use cookies to personalise them. You decide from the consent banner: if you say no the ads stay, but they are not personalised, and the tool works exactly the same.
If it is free, how do you make money?
From advertising, and that is all. We do not sell your data, there is no hidden paid plan, there is no limit that eventually asks for your card, and you do not have to sign up. The ads pay for the servers and for the time we spend writing the tools: that is how we can keep them open to everyone.
