[OT] business question

["Paul Gordon" <paul_gordon@xxxxxxxxxxx>]

I know there are a fair few self-employed/proprieters in here, so I'm
hoping
someone can cast some light on a hypothetical question...

Supposing a propieter was approaching a chosen retirement point and thus
considering selling the (successfull) business as a going concern....

On what basis is a sole propieters business value assessed?

is there a rule of thumb, such as (for example) a multiple of annual
turnover?... some other value?

Many thanks
