Costa Rica ICE, CNFL & AyA Utility Bill Calculator
Model monthly residential utility costs in Costa Rica across major distributors (CNFL, ICE, ESPH) and national water service (AyA). Integrates progressive kWh and m³ block rates, the 1.75% Bomberos charge, and exact 280 kWh & 30 m³ 13% IVA exemptions under Ley 9635.
Consumption & Utility Settings
In Costa Rica, energy efficiency directly eliminates tax overhead. Keeping electricity consumption at or below 280 kWh per month and water usage at or below 30 m³ per month saves the statutory 13% IVA on the entire bill.

Frequently Asked Questions (Costa Rica Electricity & Water)
When does 13% IVA apply to residential electricity in Costa Rica? ▾
Under Ley N° 9635 (Ley de Fortalecimiento de las Finanzas Publicas), residential electricity consumption up to 280 kWh per month is 100% exempt from the 13% Value Added Tax (IVA). If consumption exceeds 280 kWh in a billing cycle, the 13% IVA applies to the full bill.
When does 13% IVA apply to residential water bills (AyA)? ▾
Under Ley N° 9635, residential water service provided by AyA or municipal water boards is exempt from 13% IVA for consumption up to 30 cubic meters (30 m³ = 30,000 liters) per month. If water usage exceeds 30 m³, 13% IVA is assessed on the entire bill.
What is the Ley de Bomberos fee on electric bills? ▾
Ley N° 8641 establishes a 1.75% surcharge on all electric power bills where monthly consumption exceeds 100 kWh. The funds are channeled directly to the Benemerito Cuerpo de Bomberos de Costa Rica to finance nationwide firefighting and rescue operations.
How does CNFL electricity billing compare to ICE in provincial regions? ▾
CNFL serves the Greater Metropolitan Area (GAM / San Jose), while ICE serves provincial and coastal areas (Guanacaste, Puntarenas, Limon). Both apply ARESEP-approved progressive block tariffs where per-kWh costs increase once baseline blocks (200 kWh) are exceeded, though ICE coastal cooling demand typically leads to higher summer tier brackets.
What constitutes the AyA sewerage charge? ▾
For residences connected to a public sanitary sanitary network, AyA levies an alcantarillado (sewerage and wastewater treatment) fee, typically equivalent to 35% to 50% of the potable water consumption charge, plus a small fire hydrant maintenance stamp (~₡100).
