käyttöperusteiseen

Käyttöperusteiseen is a Finnish term that translates to "usage-based" or "pay-as-you-go" in English. It describes a pricing or service model where the cost or availability of a product or service is directly linked to how much it is used. This contrasts with fixed-fee or subscription models where a set amount is paid regardless of consumption.

In practice, usage-based models are found in various industries. For example, telecommunications companies might charge based on minutes of talk time, data consumed, or number of text messages sent. Cloud computing services often employ this model, billing customers for the amount of storage, processing power, or network bandwidth they utilize. Other examples include utilities like electricity and water, where consumption is metered and billed accordingly, and some software licenses that are priced per user or per transaction.

The primary advantage of a usage-based model for consumers is cost efficiency, especially for those who use a service infrequently or have variable needs. They only pay for what they consume, avoiding the cost of unused capacity. For businesses, this model can encourage adoption by lowering the initial barrier to entry and allowing customers to scale their usage as their needs grow. However, it can also lead to unpredictable costs if usage fluctuates significantly, which can be a drawback for budgeting. The transparency of billing is crucial for the success of any usage-based system.
