About the product
The benefit in kind from the P11D value and the CO2 band, the tax the driver pays on it at their own rate, the employer's Class 1A on the same figure, the advisory fuel rate for the engine, and whether the cash allowance would have left the driver better off. You type the list price, the band, the fuel and the rate; the sheet works HMRC's own steps in front of you and asks for nothing else.

For product owners
Promote Carbikly
Every listing gets one post to our X and Threads followers. It is seen once, then the traffic stops. Promotion keeps Carbikly in front of people instead.
- Back in the X and Threads rotation: Carbikly gets posted again instead of once.
- A promoted slot on the AppRater homepage, carrying a Promoted badge.
- A direct link to Carbikly from a DR45 site (Ahrefs Domain Rating), with no redirect in between.
- A labelled spot in the weekly email to AppRater subscribers, one promoted app per issue.
- Stays on the first screen however old the listing is, while new submissions push everything else down.
