Daily commuter cost at the Dartford Crossing
Twice a day, five days a week, on the 2026 Dart Charge rates: that comes to £1,750 a year on pay-as-you-go, £1,400 on pre-pay, or £25 a year on the resident pass if you live in DA or RM postcodes. This page shows the maths, the break-even points, and the answer to the question most commuters actually ask: which option is worth the bother?
Annual cost for a 5-day-a-week car commute
Two crossings a day (one in, one out) over 250 working days a year. The ONS standard year minus eight bank holidays and 23 days of average annual leave. Rounding to whole pounds.
Pay-as-you-go
£1,750/yr
£7.00 per working day at £3.50 per crossing.
Pre-pay account
£1,400/yr
£5.60 per day. Saves £350 a year against PAYG.
Resident pass
£25/yr
Flat fee, unlimited crossings, DA or RM postcodes only.
Annual commute cost by vehicle class
Same 5-days-a-week, 2-crossings-a-day, 250-day assumption. Pre-pay savings vary by class; the multi-axle HGV saves £1.20 per crossing, equivalent to £600 a year for a daily commuter.
| Vehicle | PAYG / yr | Pre-pay / yr | Saved | Resident pass / yr | Saved vs PAYG |
|---|---|---|---|---|---|
| Motorcycle | Free | Free | n/a | n/a | n/a |
| Car / van under 3.5t | £1,750 | £1,400 | £350 | £25 | £1,725 |
| 2-axle goods over 3.5t | £2,100 | £1,800 | £300 | not eligible | n/a |
| Multi-axle HGV | £4,200 | £3,600 | £600 | not eligible | n/a |
Rates and saving values per crossing are: car £3.50 / £2.80 / 70p, 2-axle goods £4.20 / £3.60 / 60p, multi-axle £8.40 / £7.20 / £1.20. The resident pass covers cars, motorhomes, minibuses (9 seats or fewer) and privately owned two-axle vans; company vehicles and HGVs are not eligible.
When each option pays for itself
Three break-even moments to know if you're weighing up the £15 pre-pay deposit and the £25 resident pass:
- £15 deposit pays back at 22 crossings. At 70p saved per car crossing on pre-pay, the £15 deposit covers itself in 22 crossings, or 11 commuting days. Daily commuters return their deposit by the end of the second week.
- £25 resident pass beats pre-pay at 9 crossings/year. If you pay £2.80 a crossing on pre-pay, 9 crossings = £25.20. The flat resident pass £25 wins from crossing #9 onward and runs unlimited from there. Daily commuters break even on day 5.
- Resident pass beats PAYG at 8 crossings/year. At £3.50 PAYG, 8 crossings = £28. The £25 pass wins from crossing #8 onward. Even a once-a-week commuter is in the money in February.
What changes the maths
- Hybrid or 4-day-week commute. Two days in, three from home cuts the year to £728 PAYG / £582 pre-pay. The £25 resident pass still wins by a huge margin if you qualify.
- Annual leave above 23 days. Each extra week off saves £35 PAYG / £28 pre-pay. Doesn't affect the resident pass.
- Sick days, weather, school holidays. The pre-pay account doesn't expire balances, so anything you don't spend stays for the next month. PAYG is per-crossing so unused days simply don't cost anything.
- Crossing only once (e.g. you cycle back). Halve every number. The case for pre-pay is still strong but the resident pass is less compelling at 1 crossing a day, 125 a year.
- Crossing during the free window. 10pm-6am is always free regardless of vehicle. Night-shift commuters get a free year, no account or pass needed.

Daily commute questions
How much does a daily Dartford commute cost in 2026?+
A 5-day-a-week car commuter doing two crossings a day spends £1,820 a year on pay-as-you-go (£3.50 x 250 working days x 2 directions). Pre-pay drops it to £1,456 (£2.80 x 500). The £25 resident pass, if you qualify, drops it to £25 flat. Vans and HGVs scale up: a Class C 2-axle goods vehicle pays £2,184 PAYG, multi-axle HGV £4,368.
When does the £15 pre-pay deposit pay itself back?+
After 22 crossings: the 70p saved per car crossing covers the deposit in about 11 days of normal commuting. After that, every crossing is pure 70p saving. By the end of a year of daily commuting, pre-pay has saved you £350 and earned its keep many times over.
Should a daily commuter use the resident pass or pre-pay?+
If you're eligible for the resident pass (DA or RM postcode), it's a no-brainer. £25 a year buys unlimited crossings. The next-cheapest option, pre-pay at £2.80, costs £1,456 a year for the same commute volume, a £1,431 difference. The pass pays for itself after 9 crossings, less than a week of commuting.
What if I commute four days a week?+
Four days at two crossings per day for 50 working weeks (200 days) costs £1,400 on PAYG, £1,120 on pre-pay, or £25 on the resident pass. The percentage savings are identical because the rate is per-crossing. The £15 deposit pays back in 11 days regardless of frequency.
Can I claim the daily Dart Charge against business mileage?+
Yes, if the crossings are business-related. The HMRC business-mileage system allows tolls and parking on top of the 45p/25p per-mile car allowance. Keep your Dart Charge account statement as proof; pre-pay accounts include downloadable monthly summaries.
What about a couple where both partners commute through?+
Two separate vehicles, one Dart Charge account: £15 deposit, both VRMs added, both get the pre-pay £2.80 rate. Annual cost for two cars commuting daily: £2,912 (vs £3,640 PAYG). The shared £25 resident pass only covers one specific vehicle, so two-commuter households can buy two passes for £50 a year total if both qualify.
