Enter the charge at each toll plaza on your route for your vehicle class. The calculator totals them for one-way or return journeys, applies any discount and spreads the cost over the trips and distance.

Also called: Road toll calculator.

## Inputs
- Toll at each plaza (one way) (default 5.50, 3.25, 7)
- Journey (options: One way, Return; default return)
- Return leg charged at (unit %; default 100)
- Number of trips (default 4)
- Discount (optional) (unit %; default 10; optional)
- One-way distance (unit km; default 210)
- Currency

## Results
- Total tolls for all trips
- Tolls per trip
- One-way tolls before discount
- Toll plazas
- Toll cost per km

## Formula

```
One way = Σ plaza tolls;  Per trip = One way × (1 + Return% ÷ 100 if return) × (1 − Discount% ÷ 100);  Total = Per trip × Trips
```

Where:
- Return%: share of the outbound toll charged on the way back
- Discount%: any tag or frequent-user reduction

## Worked example
1. One way = 5.50 + 3.25 + 7 = 15.75.
2. Return trip = 15.75 × 2 = 31.50; less 10% = 28.35.
3. Four trips = 28.35 × 4 = 113.40, or 28.35 ÷ 420 km = 0.0675 per km.

**Result:** Four return trips through three plazas cost 113.40 in tolls after a 10% discount.

## What the result means

Compare the toll cost per km with the fuel and time a toll-free route would add. For trucks, tolls often depend on axles or weight, so make sure the plaza charges match your vehicle class.

## Assumptions and limits
- The same plazas and charges apply on every trip.
- Distance-based or time-of-day tolling is not modelled; enter the charge you would actually pay at each point.

## Questions

### Where do I find the toll amounts?

From the toll operator’s published rate table for your vehicle class, or your route planner. Rates change, so check before relying on them.

### How do I handle a return-within-24-hours discount?

Set “Return leg charged at” to the percentage the operator charges for the return journey.
