Contract adjustment by inflation (IPCA)

Every annual contract gets adjusted, and almost nobody runs the numbers at renewal. Here the accumulated index comes straight from the Central Bank.

Frequently asked

What is the 12-month accumulated IPCA?

The figure shown in the tool comes from the Central Bank's official series and is recalculated on each monthly release. A price index compounds month by month, it is not summed.

Can I use another index?

Yes. The index field is editable, so you can apply IGP-M, INPC or a rate agreed in the contract without redoing the maths by hand.

This is the pocket version

The tool above solves one calculation. What I do under contract is keep it running inside your system, on your data, with nobody typing anything.
