Day tickets or a monthly pass?

Commute cost calculator

Estimate monthly park-and-ride spending from your travel days, daily parking and return fare. Compare a monthly pass, including the parking it leaves you to pay, and find the first whole day it saves money.

1. How often do you commute?

Enter travel days by

Travel days per weekA whole number from 0 to 7.

Weeks per month52 ÷ 12 is about 4.33 weeks. For a particular month, use its actual travel-day count.

Travel days this monthA whole number from 0 to 31. Exclude holidays and days at home.

2. Your day-by-day costs

Daily parking (£ per vehicle)Total for one commuting day.

3. Optional monthly pass

What does this pass include?

Select both only when the operator confirms it. Pass validity must match the month, route and travel times used here.

All example values are illustrative inputs, not live fares. Amounts are in pounds sterling (£).

Your cost comparison

The monthly cost formula

Monthly travel days = travel days per week × weeks per month, or your entered actual monthly days. Day-ticket spending = monthly travel days × (daily parking + daily return fare).

For a transport-only pass, monthly spending = pass price + monthly travel days × daily parking. When a pass includes parking as well, monthly spending = pass price. The comparison assumes you buy one pass covering the same period as the day-ticket estimate.

How many days make a monthly pass worthwhile?

Divide the pass price by the daily cost it replaces. A transport-only pass replaces the return fare; a pass covering both replaces parking plus the return fare. If the answer is a whole number, that day is a tie: the following day is the first saving. If the replaced daily cost is £0, a paid pass cannot save money on these inputs.

Worked example: three days a week

At 3 days per week × 52 ÷ 12 weeks, the average is 13 travel days a month. With £2 daily parking and a £5 return fare, day-ticket spending is £91. An illustrative £60 transport-only pass still needs £26 parking, giving £86 total: £5 less.

The pass equals 12 × £5 return fares, so 12 days is a tie and day 13 is the first saving. If the same £60 pass also includes parking, it first saves money on day 9 (£63 day-ticket spending versus £60).

Plan for the month you actually travel

Weekly averages spread travel across a year; they do not deduct annual leave or bank holidays. Use actual monthly days when comparing a calendar-month pass, especially with hybrid working. Four-week tickets, flexi bundles and annual passes have different validity periods: compare those separately rather than treating them as monthly passes.

Fuel, time, refunds, tax treatment and other travel expenses are outside this estimate. A pass may be useful for other trips, but their value is not included. For a family or group outing, try the whole-trip park-and-ride cost calculator.

Use the right local ticket rules

Ticket conditions vary by operator and location. Check child ages, accompanying-adult rules, group limits, travel times, routes, zones and whether a return is included before entering a price. Unknown prices should be checked, not entered as zero.

Our methodology separates parking from transport because an offer may combine them or cover only one. For a combined ticket, enter its full amount once and set the other component to £0 only when inclusion is confirmed. These calculators compare entered costs; they do not verify availability, eligibility or live tariffs.
