# Check Whether Cheaper Fuel Pays for the Detour — Free

The station with the lower board price is not always the cheaper fill-up once the detour burns fuel of its own. One receipt line: purchase saving on the litres you buy, minus the fuel the extra kilometres consume.

**Free and complete.** This guide is a standalone free tool — no account, no card, anywhere. The only paid option is one optional extra outcome: $4 one-time. Nothing in the free tier is gated.

## Who it's for

Drivers comparing two fuel stops with a detour

## What's free

- one complete unwatermarked fuel-detour receipt run in the app
- three labeled samples and unlimited article-demo calculations
- complete result text and a user-triggered input-state link

## Optional paid add-on

**$4 one-time.**

- unlimited subsequent fuel-detour receipt app calculations after a local convenience signal
- print the fuel-detour receipt with visible assumptions and its safety boundary
- CSV of the displayed net currency units and row workings; conditional estimate uses your manual-retyping minutes
- five local reading summaries (headline/count/time), not saved full inputs or cross-device backups

## Sources & verification
