Are Fuel Cards Worth It? How Much Could Your Business Actually Save?
Are fuel cards worth it? There is no universal yes or no.
For some businesses, a fuel card can reduce the effective cost of regular fuel purchases. For others, the advertised saving may look better than the result once network coverage and fees are taken into account.
The important question is therefore not simply how many pence per litre a card advertises.
It is:
How much could your business actually save after considering where your drivers refuel and what the card costs?
Our guide explains how fuel cards work and how businesses use them. If you already understand the basics, this article looks at the more important question: whether a fuel card is financially worthwhile for your fleet.
Do Fuel Cards Actually Save Money?
They can, but the saving depends on how your fleet uses fuel.
A fuel card’s potential saving comes from the difference between the fuel price or discount available through the card and the amount your business would otherwise pay. But the calculation also needs to account for the proportion of your fuel that can actually be purchased through the card’s network and any applicable fees.
Bramley’s fuel-card calculation is:
Annual saving = pence-per-litre discount × the share of litres that land on the card’s network − account and per-card fees
That formula is deliberately simple.
A larger discount can produce a larger saving when your fleet uses enough fuel through the network. But a card with a smaller discount can potentially produce a better result if its network fits your routes more closely.
This is why there is no single fuel card that is automatically the most worthwhile for every business.
What Determines How Much You Save?
Several factors can change the result.
Your fuel usage
The amount of fuel your fleet uses is one of the starting points.
A per-litre saving has a larger potential effect when it is applied to more litres. A business using a small amount of fuel may see a relatively small gross saving, while a higher-volume fleet has more fuel purchases against which the saving can apply.
Bramley’s fuel calculator therefore starts by asking for the litres used by the whole fleet each month.
Your network coverage
This is just as important as the advertised discount.
Suppose a fuel card advertises a substantial saving per litre, but your drivers regularly refuel at locations outside its network.
Those litres do not benefit from that card’s saving.
The result is why Bramley’s comparison estimates the share of litres that land on each card’s network according to route type.
A card that fits your routes well can therefore be more useful than one with a larger headline discount but poorer practical coverage.
Your card and account fees
Fees reduce the saving.
Depending on the account, costs can include a monthly account fee, an annual fee per card or an underused-account fee where applicable.
The comparison therefore looks at the saving after fees rather than treating the gross fuel discount as the final result.
Because providers can price according to fleet size, volume and route profile, actual pricing can vary and may be negotiated.
Are Fuel Cards Cheaper Than Paying at the Pump?
Not necessarily.
A fuel card can offer a discount or a particular pricing arrangement, but that does not automatically mean it will produce the lowest overall cost for every business.
There are several reasons.
First, fuel-card pricing varies between providers.
Second, your drivers may only be able to use some of the card’s network.
Third, account and card fees can reduce the saving.
And fourth, different fuel cards can use different pricing models.
The useful comparison is therefore the overall cost to your business, rather than simply comparing the largest pence-per-litre figure.
Card A offers a larger discount but only fits a smaller share of your normal refuelling.
By comparison, Card B offers a smaller discount but fits a much larger share of your routes.
As a result, Card B could potentially produce the larger annual saving.
That is the kind of difference a simple headline comparison can miss.
Is a Bigger Fuel Discount Always Better?
No.
A fuel-card discount only has value when your business can actually use it.
This is particularly important for fleets with established routes. If drivers regularly have to detour to reach a participating station, the apparent saving needs to be considered against the practical cost of doing so.
Bramley’s fuel comparison accounts for this by estimating an on-network share for the relevant route type.
The result is not a promise that a particular fleet will achieve a specific saving. It is an estimate based on the assumptions shown for each card.
That distinction matters because fuel-card providers can price according to fleet size, volume and route profile, and negotiated pricing can differ between businesses.
Pump-Price Discounts vs Fixed Weekly Pricing
Another reason fuel cards cannot all be compared in exactly the same way is that they can use different pricing models.
A pump-price card takes a stated amount off the price at the pump.
A fixed weekly pricing card uses a set national price for the week rather than simply discounting the price displayed at the individual forecourt.
Commercial networks and reseller cards can use fixed weekly pricing, while branded and supermarket cards can use pump-price discounts.
Neither model is automatically better for every business.
The right comparison depends on your fleet’s routes, where it refuels and the pricing offered by the provider.
When Could a Fuel Card Be Worth It?
A fuel card is more likely to be worth considering when its network fits your normal routes and the resulting fuel saving is greater than the costs attached to the account.
That makes your own fuel usage the starting point.
Ask:
- How many litres does the fleet use each month?
- Where do drivers normally refuel?
- Which networks fit those routes?
- What saving is available?
- What fees apply?
- Does the card cover the way your fleet uses fuel?
There is no minimum fleet size or universal fuel volume at which a fuel card suddenly becomes worthwhile. The result depends on the particular pricing, network and usage involved.
For the same reason, a card that works well for one business may not be the right choice for another.
What About Electric Vehicles?
Fuel-card value can also change when a fleet includes electric vehicles.
Some cards support public EV charging on the same account and invoice, while others are fuel only.
If a significant part of your fleet is electric, a fuel-only card may cover a shrinking share of the fleet’s energy spending.
Bramley’s calculator flags fuel-only cards as a weak fit when 30% or more of the fleet is electric.
That doesn’t mean every mixed fleet needs the same solution. It means the type of energy your vehicles use needs to be included when assessing whether a card is worthwhile.
How Much Could a Fuel Card Save?
There is no reliable single figure for every business because the result depends on the fleet.
Bramley’s comparison uses 1,500 litres per month as its default example for comparing fuel cards.
The potential calculation starts with the fuel volume and then considers the share of litres that land on the relevant network and the applicable fees.
For illustration, if all 1,500 litres were eligible for a 5p-per-litre saving, the gross saving would be:
1,500 × £0.05 = £75 per month
or:
£900 per year before fees.
But that is only an illustration of the calculation. It should not be treated as a quoted saving from a particular provider.
If only part of the fleet’s fuel can use the network, the result changes. Fees then reduce the final figure further.
That is why Bramley’s calculator shows an estimated annual saving, rather than presenting the advertised discount as a guaranteed result.
Why Fuel-Card Quotes Matter
Fuel-card pricing can be different from the figures you see in a comparison.
Providers may price according to fleet size, volume and route profile, and negotiated pricing can affect the final pence-per-litre figure.
Bramley’s fuel-card figures are therefore labelled as indicative assumptions.
This is different from the credit-card comparison, where published issuer figures are used.
The purpose of the fuel-card comparison is to help a business understand the structure of the decision:
Which network fits my routes?
How much potential saving does the pricing create?
What fees reduce that saving?
The provider’s final quote should then be checked before making a decision.
How Bramley Decides Which Fuel Card Is Worth Considering
Bramley doesn’t simply rank fuel cards by the biggest advertised discount.
The comparison estimates:
pence-per-litre saving × on-network litres − fees
Network fit is estimated according to route type.
The calculator also considers EV suitability and flags fuel-only cards where they may be a weak fit for an EV-heavy fleet.
This approach is designed to answer a more useful question than “Which fuel card has the biggest discount?”
It asks:
Which card could produce the strongest estimated saving for this type of fleet?
The answer can change when the assumptions change.
So, Are Fuel Cards Worth It?
They can be, but there is no universal answer.
A fuel card is worth considering when the pricing, network and fees work for the way your business actually buys fuel.
The biggest advertised discount is not necessarily the biggest real saving. A card with broad practical coverage can potentially outperform one with a deeper discount if more of your fleet’s fuel purchases can use it.
The same applies to fees. A saving that looks attractive before costs may be much smaller after account and card charges.
So rather than asking:
“Which fuel card is cheapest?”
ask:
“Which fuel card gives my fleet the best estimated saving after network coverage and fees?”
Compare Fuel Cards Based on Your Fleet
Bramley Money’s fuel calculator lets you compare the fuel cards we track using your fleet’s monthly fuel usage and the assumptions behind each comparison.
The ranking considers the relationship between fuel savings, network coverage and fees rather than relying on a headline discount alone.
Because fuel-card pricing can vary and providers may negotiate individual rates, the results are estimates rather than quotes.
If you are deciding whether a fuel card is worth it for your business, put your fleet’s numbers into the calculator and see how the ranking changes.
