Calculadora Alquiler 2026

Calculadora Alquiler 2026 is a focused Spain-only rental rule utility for the Ley 12/2023 framework (Ley por el Derecho a la Vivienda) and the BOE 2026 reference index from the Instituto Nacional de Estadistica. It is built for one job: helping landlords, tenants, and small property managers compare real Spanish rent scenarios more clearly, without a spreadsheet and without an account. Two clear calculators: - Annual rent update for ongoing contracts: applies the official 2026 reference index when the law requires it, with a transparent breakdown of the previous rent, the index value entered, and the new ceiling. - New contract in a restricted zone (zona de mercado residencial tensionado): compares your proposed rent to the prior contract reference and to the published index limits under articles 17 and 18 of the LAU as modified by Ley 12/2023. What you get: - Scenario comparison side by side - Zone and index assistant with direct links to the BOE consolidated text of the LAU, the SERPAVI listing of declared restricted municipalities, and the INE reference index page - Shareable premium PDF report for landlords, tenants, or asesorias - Local saved history with no cloud account - No registration, no in-house analytics, no tracking pixels Free version: - Rewarded ad before each calculation result - May also show banner or interstitial Google ads on free surfaces Premium one-time unlock: - Removes ads on result screens - Shareable PDF report - Unlimited saved scenarios - All future 2026 and 2027 index updates included for the same purchase Personas it fits: - Small landlords renewing one or two long-term contracts - Tenants checking that a renewal letter respects the legal ceiling - Asesorias and property managers preparing a contract review for clients in Madrid, Barcelona, Valencia, the Balearics, and other declared zones Important: - Results are guidance only and do not replace official restricted-zone verification at the SERPAVI or municipality level - When the law requires the official reference index value, you must enter the published value for the specific property - This app is an independent informational tool. It is not affiliated with the Ministerio de Vivienda, the BOE, the INE, the SERPAVI, or any Spanish public authority. It does not replace legal advice, a contract review by a colegiado lawyer, or a formal valoracion. (c) 2026 Cosmic Production d.o.o.
