The CPI rent increase formula
CPI is not added month by month: you divide the index of the last month by the one of the month before the first, so each month's inflation compounds on the previous one.
Current rent times CPI of the last month divided by CPI of the month before the first, equals New rent
CPI over the last 12 months
National general level, base December 2016 = 100. The indices are the ones published by INDEC.

Which law governs your lease
A lease follows the rule in force on the day it was signed, even if the law changes later. Law 27,551 leases have already ended and Law 27,737 leases end before the end of 2026: almost every lease running today follows Decree 70/2023, which sets no index and no minimum frequency.
| Signed | Rule | Index | Adjustment |
|---|---|---|---|
| July 1, 2020 to October 17, 2023 | Law 27,551 | Central Bank ICL | Yearly |
| October 18 to December 28, 2023 | Law 27,737 | Casa Propia coefficient | Every 6 months or more |
| Since December 29, 2023 | Decree 70/2023 | Whatever the parties agree, usually CPI | Whatever the parties agree |
How the increase is calculated
Each adjustment multiplies the current rent by the CPI change over the months it covers: the index of the last month divided by the index of the month before the first one. For a quarterly adjustment in April, the calculator takes the months of the period by default, January, February and March: rent × March CPI ÷ December CPI. If your lease uses the latest months published on the adjustment date (December to February), switch with one tap.
We use INDEC's national general-level CPI, base December 2016 = 100, the index most Argentine leases name. We read it from INDEC's official API and update it when new data comes out, in the middle of each month. If an adjustment needs a month INDEC has not published yet, we repeat the latest published change until the figure comes out; you can pick another scenario, such as what the market expects in the BCRA's REM survey, or change each month.
Each increase is rounded to one decimal before it is applied, as the market does: if the index rises 5.91%, the rent rises 5.9%. Each adjustment starts from the previous amount.
Frequently asked questions
Still have a question?
Message us on WhatsAppIt depends on your lease. There are two readings: the months of the period itself (for a quarterly increase in April, January, February and March), which is what the calculator takes by default, or the latest months INDEC has published on the adjustment date (December, January and February). With the months of the period, the final amount is known when INDEC publishes March, in mid-April. The calculator lets you switch readings with one tap.
The one in force when you signed it. Leases signed between July 2020 and October 17, 2023 keep Law 27,551: yearly adjustment by ICL. Those signed from October 18 to December 28, 2023 follow Law 27,737: adjustment every 6 months by the Casa Propia coefficient. Since December 29, 2023, Decree 70/2023 lets the parties agree on the index, frequency and currency. If the lease sets no term, a home rental lasts 2 years, and the tenant can leave early by paying 10% of the remaining rent.
Check the adjustment clause. If you signed under Law 27,551, it uses the ICL published by the Central Bank, an average of inflation and wages. This calculator is for leases adjusted by CPI, the most used index in new leases since 2024.
Yes, as an estimate. For months INDEC has not published yet, the calculator repeats the latest published change; you can pick another scenario, such as what the market expects in the Central Bank's REM survey, or change each month by dragging its bar or typing the figure. The final amount is confirmed when the data comes out, in the middle of each month.
Yes. Enter the lease and copy the notice, or send it straight on WhatsApp: it includes the new amount, the percentage, the math and the INDEC link. If you manage many leases, Orbi can answer your tenants' and leads' questions on WhatsApp.
