The problem
Two drivers can be offered the same fare and still get a different result from the job.
Why?
Because the car costs money to move.
A fuel-efficient petrol car, a less efficient petrol car and an electric vehicle can all have different energy costs over the same distance.
The headline fare does not show that difference.
Why it matters
Suppose two drivers both see a £30 offer.
If one vehicle uses about £3.60 of fuel or energy over the analysed distance and another uses £6.60, the fare is the same but the amount left after that known running cost is different.
That does not mean the first driver made £26.40 profit or the second made £23.40 profit. There can be many other business costs.
But it is still more useful than pretending the £30 headline fare costs nothing to deliver.
How to work it out
A simple approach is:
- Work out the analysed distance for the offer.
- Estimate the fuel or energy cost for that distance using the vehicle’s real-world settings or a reasonable configured assumption.
- Subtract that known cost from the fare.
Simple formula:
Fare − estimated fuel/energy cost = after-fuel estimate
That result is useful for comparison, but it is not net profit.
Simple worked example
Illustrative example
A ride has:
- Fare: £30
- Analysed distance: 30 miles
Vehicle A
Illustrative fuel/energy cost: 12p per mile
30 miles × £0.12 = £3.60
£30 − £3.60 = £26.40 after fuel/energy
Vehicle B
Illustrative fuel/energy cost: 22p per mile
30 miles × £0.22 = £6.60
£30 − £6.60 = £23.40 after fuel/energy
Same fare. Same distance. Different known vehicle cost.
The difference is £3 on one offer.
Across a full week, those differences can add up.
What to watch out for
Fuel or energy is not the only vehicle cost
Other real-world costs may include:
- insurance;
- finance or depreciation;
- maintenance and tyres;
- tax;
- licensing;
- cleaning;
- and other business costs.
This guide does not claim FareWorth currently calculates all of them.
Real-world efficiency changes
Cold weather, traffic, driving style, tyre pressure, speed and heating or air conditioning can affect actual consumption.
Electricity pricing can vary
Home charging, public charging and rapid charging can have very different prices.
A cheaper vehicle does not automatically make every offer good
Time, pickup and total distance still matter.
How FareWorth helps
FareWorth lets the driver use their own vehicle and fuel or energy settings instead of relying on one generic vehicle assumption.
Those settings can be used to add estimated running-cost context to the offer analysis.
FareWorth can show an After Fuel Est. in reporting where the required data is available.
That wording matters. It is an estimate after the known fuel or energy calculation. It is not the same as full business profit.
The driver can therefore compare offers using more than just the headline fare.
Practical takeaway
- The same fare can be worth different amounts in different vehicles.
- Fuel or energy cost belongs in the decision.
- “After fuel” is not the same as net profit.
- Use settings that reflect your own vehicle as closely as practical.
- Keep other business costs in mind when judging your wider earnings.
