CPI readjustment calculator for contracts

The incessant phenomenon of inflation demands that various legal obligations, monetary debts, and alimony be duly updated over time. The law imposes the obligation to maintain the original purchasing power of the stipulated money through the technical application of the variations of the Consumer Price Index. Our readjustment calculator comprehensively uses the extensive official historical series published monthly by the National Institute of Statistics, performing the necessary mathematical multiplications to obtain the exact aggregate inflation between two periods.

Manually drafting these readjustments is prone to massive arithmetic failures, since the simple addition of the month to month percentages is not enough. The legally validated procedure requires calculating the compound interest resulting from the factor of each month. Applying this complex mechanism is extremely useful and practically recurrent when it is required to calculate the readjustment of value for lease contracts, both residential and commercial, which usually include clauses for quarterly or semiannual updating.

We suggest using this valuable platform before issuing liquidations of judicial sentences or invoicing exchange differences in continuous services. Having an indexed calculation tool that faithfully reflects the rise in the cost of living allows demanding the full payment of the real debt and avoiding unjust enrichment that would end in extensive collection disputes and long civil arbitrations over differences in the final amounts collected.

Compound calculation of the official monthly variation certified by statistical authorities.
Allows you to quickly bring the money of the past to its equivalent in present value.
It has a robust history of percentages that allows projecting long term obligations.

Frequently Asked Questions

What is the most common mathematical error when attempting to manually readjust an amount?+

The most widespread error is simply arithmetically adding the inflation of each month reported by the news. To obtain the real percentage for the complete period, it is strictly necessary to iteratively multiply all the consecutive monthly factors reported by the statistical authority.

Why does the absolute majority of contracts require a readjustment agreed upon annually?+

The national economy suffers from progressive devaluation, therefore, legislation encourages and protects readjustment clauses to prevent a payment frozen for years from dramatically losing its authentic purchasing power as a result of the increase in the cost of living.

Is there any legal maximum limit to apply the charges of readjustments indexed to the Price Index?+

There is no absolute cap or maximum limit predetermined by the legal system regarding the percentage of readjustment of the cost of living, since the judicial or conventional mandate simply orders to keep the constant value of the original money agreed between the parties intact.
