Legal calculators for lawyers: costs, deadlines, severance and compensation in one place

One client calls to ask how much compensation they would get for dismissal, another wants to know what losing a case could cost. You do these sums several times a month, usually in a spreadsheet inherited from a colleague, with a formula nobody remembers checking since the last reform.

The risk is not that the sum is hard. It is that it is slow, that every lawyer in the firm does it their own way, and that the figure that ends up in the email to the client cannot be reproduced when someone questions it.

How Lexiel solves it, step by step

Lexiel gathers the firm's everyday calculators on one screen, inside the app and also on the public website at lexiel.ai/en/tools. They are deterministic: no AI is involved, so the same input always gives the same result.

1. Open Tools from the side menu of the app. Calculators are grouped by category: Employment, Tax, Procedural, Social Security, Civil and family, Commercial, Privacy.
2. Filter by category or type what you need in the search box (for example "severance", "deadline" or "mortgage").
3. Open the calculator, fill in the case data and read the result. Available ones include court costs, deadlines, compensation, severance, capital gains tax, income tax and court fees.
4. From the "My day" screen you have quick shortcuts to the most used ones (deadlines, interest, compensation, seizure, severance and fees).

What it does not do

• It does not give a legal assessment of the case: it calculates from the data you enter, and making sure that data is right remains your responsibility.
• It does not replace reading the applicable rule: if a figure is decisive for a brief, check it against the official source.
• It does not use artificial intelligence: that makes it predictable, but it will not draft or explain the result either.
