How it works
aviso previo calculadora — the short version
The aviso previo calculadora question usually comes up mid-conversation — with a partner, a client, a tax adviser. Aviso Prévio calculadora is the tool you can pull up on a phone and settle it in thirty seconds.
Contracts are boring until something goes wrong; this gives you the paper trail in advance. Check the period you are paid for, not the calendar month — then work it out and the rest of this page explains what the answer means.
Work out the Brazilian proportional notice period (30 days + 3 per year of service, capped at 90) and notice-in-lieu amount.
A worked example, step by step
Consider a realistic scenario and follow it through:

Scenarios where Aviso Prévio calculadora pays off
Aviso Prévio calculadora is aimed at people arriving with questions like these:
- "Aviso prévio proporcional"
- "Aviso prévio indenizado"
- "Aviso trabalhado"
- "What is aviso previo"
- "How to calculate aviso previo"
- "Aviso previo formula"
When it isn't the right tool
Every tool has an edge where it stops being the right answer. Aviso Prévio calculadora is no exception:
- For legally binding tax or medical decisions — cross-check with HMRC, NHS or a qualified professional.
- For very large or very small extremes the rounding error outgrows the useful precision.
- When the underlying rate or threshold has changed since the page was last reviewed — always verify with the primary source.
- When the input you have is already a derived figure (net of something) — feeding it in as "gross" will double-subtract.
Five things that trip everyone up
Every time you work it out for a new scenario, one of these creeps in — it's worth knowing them ahead of time.
- Mixing up units — grams in one field, ounces in another, then wondering why the answer is off.
- Treating a percentage as a whole number. 20% means 0.20 in the maths, not 20.
- Rounding at every step. Keep four decimals internally and only round the final number.
- Using last year's thresholds. If the page isn't dated, assume it's stale and check GOV.UK.
- Reading a tool like this as advice. It is maths, not a decision — the decision is still yours.
The sources behind the numbers
Where the maths needs an external authority, we cross-check against:
- CLT
- TST
