Station A vs station B comparison

A cheaper price is not always a better deal. This calculator compares pump savings, detour cost and real net savings before choosing a station.

Fuel prices A/B
Detour or position
Real verdict

Compare two stations

Enter two prices, planned fuel volume and detour distance. Coordinates are optional for prefilling or estimating distance.

Position, search or prefill

If you arrive from a station page, Tankly can prefill station A. Otherwise, enter prices manually. Without a routing API, coordinate-based distance is an estimate you should adjust.

Calculation method

How the best station is calculated

The calculation first compares the price gap over the refuel volume. It then subtracts the fuel consumed during the detour. If the result is positive, station B is truly profitable; otherwise, station A remains preferable.

real saving = ((price A - price B) × liters) - (detour km × consumption ÷ 100 × price B)
Example

Station A vs station B example

Station A at 1.86 EUR/L, station B at 1.78 EUR/L, 45 L to refuel, an 8 km detour and 6.5 L/100 km consumption.

Gross savings are 3.60 EUR, the detour costs 0.93 EUR and real net savings reach about 2.67 EUR. Station B is worth it.

Compare two fuel stations in a useful way

This station A vs station B comparison tool answers a simple question: is a cheaper station really worth the detour? It combines fuel prices, refuel volume, vehicle consumption and detour distance to produce a practical verdict.

Compare real pump scenarios

The tool helps you choose between two stations or two manually entered prices instead of looking only at the advertised price per liter.

Clear decision support

The result separates gross savings, detour cost and real net savings so you can instantly see whether station B is truly better.

Built for Tankly flows

From a station page, station A can be prefilled with its fuel and price. You then freely choose station B or enter a manual price.

When comparing two fuel stations, looking only at the price gap is not enough. If the cheaper station requires a detour, part of the apparent saving is lost in extra fuel consumed on the road. This station comparison calculator therefore focuses on real cost rather than on the sticker price alone.

The page targets searches such as fuel station comparison, is a cheaper station worth the detour, or compare two gas stations. It fits Tankly especially well because it extends price comparison into an actual user decision.
