Formula Used

Cost Calculation

The cost is calculated based on the selected zone and the number of days you'll be traveling. The base cost is the same for both Oyster Cards and Travelcards in the same zone.

For Oyster Cards: Cost = Base Cost × (Number of Days / 30)

For Travelcards: Cost = Base Cost × (Number of Days / 7)

Assumptions

This calculator assumes you'll use the ticket for the maximum number of days it's valid. For example, a 7-day Travelcard will be fully used if you travel for 7 days.

Costs are based on standard adult fares and may vary for children, seniors, or other special cases.

Worked Example

Let's say you're traveling in Zone 2 for 14 days. Here's how the calculation works:

Oyster Card Calculation

Base cost for Zone 2: £38.50

Number of days: 14

Cost = £38.50 × (14 / 30) = £15.47

Travelcard Calculation

Base cost for Zone 2: £38.50

Number of days: 14

Number of 7-day Travelcards needed: 2

Cost = £38.50 × 2 = £77.00

In this example, the Oyster Card is significantly cheaper at £15.47 compared to £77.00 for Travelcards.
