Here's what you could expect, if your app/game is good enough, based on 100,000 copies of a game sold.
Game cost (0.99 x 100000) = $99,000
After iPhone App Store's cut, you're left with 70% of $99,000 (99000 x 0.70) = 69,300
After TGC take their cut you're left with 70% of $69,300 (69300 x 0.70) = $48,510
If you live in the UK, you are taxed at 40% for anything over ?35,000 and 50% for ?150,000 and over, as far as I
know.
With the current USD-GBP conversion rate at rougly (?0.63), (48510 x 0.63) = ?30,561.30p.
After the UK Inland Revenue take their 40%, you are left with 60% (30561.30 x 0.60) = ?18,336.78p
Considering TGC takes care of the deployment through tier-1, what is everyone complaining about?. If you game takes
you about a month then 18 grand for a month's work is great. Most people have to work an 8 hour/day for a year, hard
graft, to take home that amount after tax.
