How it works
aviso previo calculadora — the short version
Use this Aviso Prévio calculadora when you need a aviso previo calculadora you can trust — clean inputs, transparent steps, zero fluff.
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.
On this page you will see Aviso prévio, Proporcional and Indenizado treated as first-class terms — each one is linked to the calculators and references that use it, so you can follow the thread without retyping queries into a search bar.
If it helps, jump straight to the Employment hub or compare with the Brazilian Termination Pay Calculator and the 13th Salary Calculator (Brazil) — those two calcs are the ones readers usually open right after this page.
A worked example, step by step
An example grounded in actual employment figures beats a generic one every time:
Work out the Brazilian proportional notice period (30 days + 3 per year of service, capped at 90) and notice-in-lieu amount.

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.
- Flipping the numerator and denominator — half the "wrong" answers on this type of calculation are an inverted ratio.
- Not noticing that one input is already pre-rounded by the source that gave it to you.
- Forgetting that negative inputs behave differently — the formula assumes positive magnitudes unless the tool says otherwise.
- Running the calculation once and believing it. Always sanity-check against an order-of-magnitude estimate done in your head.
- Copying numbers from a PDF and picking up hidden thousands separators as decimal points.
The sources behind the numbers
Where the maths needs an external authority, we cross-check against:
- CLT
- TST
