Monetary revaluation of an Italian claim
Enter the amount, the month it was due and the target month: the result is the same sum in money of that month.
Foreign creditors, heirs and buyers dealing with Italy often meet the phrase rivalutazione monetaria: a sum fixed in one month, restated in the money of a later month. It applies, for example, to unpaid debts, damages assessed long before payment, a price or penalty to bring up to date, or a deposit to return. The calculation follows Istat’s method: divide the FOI index excluding tobacco of the target month by that of the starting month, multiply by the base-linking coefficients if the period crosses a base change, and round to three decimals. With current data, €20,000 from June 2019 is worth €24,660.00 in September 2026, a coefficient of 1.233 (23.3%). This is only the purchasing-power adjustment. Whether revaluation is due at all, from which date and whether interest is added on top are legal questions that depend on the contract, the judgment or the rule behind the claim, and this tool does not answer them.

What the calculation leaves out
- Interest of any kind, which follows its own rules.
- Whether the claim is revaluable at all: some debts are by law or judgment, others are not.
- Reduced shares: a commercial rent at 75% is updated year by year, see the Istat rent update.
The method and the base-linking coefficients are explained in the Istat revaluation, based on the Istat methodological note. For a maintenance allowance, see the allowance update. For a real dispute, an Italian lawyer is the right person to fix the dates.
