A tariff is a schedule of rates or charges for a service, such as electricity, water, or telecommunication services. It outlines how much a customer will pay based on their usage or a fixed fee.

An advantage of Option A (Contract) is that it offers a predictable monthly cost for a set amount of call minutes, which can help with budgeting. If Lelo uses close to or less than the included 300 minutes, the per-minute cost is effectively lower than pay-as-you-go.

Choosing the wrong tariff can significantly affect Lelo's monthly budget by leading to unexpected or higher expenses. For example, if Lelo chooses a pay-as-you-go tariff (Option B) but makes many calls, her costs could be much higher than a contract (Option A) that includes a large bundle of minutes. Conversely, if she chooses a contract (Option A) but makes very few calls, she might be paying a fixed fee for minutes she doesn't use, which is also inefficient spending. This miscalculation can strain her budget, leaving less money for other necessities.
